Influencer marketing can be a powerful growth driver for small ecommerce businesses – if you know how to measure its impact.

Many store owners partner with influencers to boost brand awareness, engagement, and sales, but then struggle to quantify influencer campaign success. This how-to guide will walk you through setting clear goals, tracking influencer marketing metrics, calculating ROI, and using benchmarks and tools to interpret influencer performance. By the end, you’ll be able to confidently answer the question: “Was my influencer campaign worth it?”

Why Measurement Matters?

According to industry research, influencer campaigns deliver a high return – roughly $5 to $6 in revenue for every $1 spent on average.

But not every campaign hits that mark. Tracking the right KPIs for influencer marketing lets you double down on what works and fix what doesn’t, ensuring you get the most out of your budget. It also provides hard data to justify your influencer spend to stakeholders.

Let’s dive into a step-by-step approach to measuring influencer marketing success for your ecommerce store.

Set Clear Goals for Your Influencer Campaigns

Every successful marketing effort starts with a goal. In influencer marketing, setting specific objectives for each campaign is crucial. Ask yourself what you want to achieve with the influencer collaboration. Common goals include increasing brand awareness, boosting social engagement, driving website traffic, or generating conversions.

Make Goals SMART: Just as with any project, apply the SMART framework – make goals Specific, Measurable, Achievable, Relevant, and Time-bound. For example, instead of a vague goal like “get more sales,” a SMART goal would be: “Generate 50 new online orders from influencer referrals in Q3.” This clarity guides your strategy and provides a concrete target to measure against.

Setting clear goals upfront creates a roadmap for measurement. If your aim is brand awareness, you might track metrics like reach and follower growth. If it’s sales, you’ll focus on referral traffic, conversion rate, and revenue. The key is alignment: your metrics should map directly to your campaign objectives. For instance, an influencer campaign to improve brand awareness could use impressions and new social followers as KPIs, whereas a campaign for sales would prioritize click-throughs and conversions.

Finally, communicate these goals to your influencer. Ensure they know what success looks like for your brand – whether it’s driving 1,000 clicks to a landing page or achieving a 5% engagement rate on their posts. When both you and the creator understand the objectives, it’s easier to create content and track results that fulfill those goals.

Key Influencer Marketing Metrics to Track

Once your goals are defined, determine which influencer marketing metrics will signal success. There are tons of potential KPIs to choose from, so focus on the ones most relevant to your objectives. Below, we break down the key metrics and influencer engagement metrics that ecommerce brands should monitor, and how to interpret them.

1. Reach and Impressions

Reach is the number of unique people who see an influencer’s content, and impressions are the total number of times the content is displayed. These metrics tell you the potential audience exposure of your campaign. Essentially, reach answers “How many people could have seen our message?”

Why it matters: A high reach indicates your brand is getting in front of a lot of eyeballs, which is the first step in building awareness. If your goal is brand awareness or visibility, reach and impressions are critical KPIs. For example, if an influencer has 50,000 followers, that’s the maximum reach, but due to social algorithms, the actual post reach might be, say, 20,000. Impressions might be 30,000 if some people view it twice. By tracking these numbers, you gauge how widely your campaign is spreading.

Tip: Compare the reach to the influencer’s follower count to assess content distribution. If an influencer consistently reaches a low percentage of their followers, their audience may be inactive or the platform’s algorithm isn’t favoring their posts – a red flag for future partnerships. On the other hand, if impressions far exceed reach, it means some followers viewed the content multiple times or it was shared – a sign of strong interest.

2. Engagement  and Engagement Rate

Engagement measures how actively viewers interact with the influencer’s content. Key engagement metrics include likes, comments, shares, saves, and clicks. High engagement means the content resonated with the audience, prompting them to take action. Engagement goes beyond just being seen – it shows audience interest and interaction with your brand message.

Engagement rate is one of the most important metrics in influencer marketing analytics. It’s typically calculated as the percentage of an influencer’s audience that engages with a piece of content. For example, engagement rate =  × 100. This metric normalizes engagement to account for audience size, allowing you to compare influencers of different scales.

Why it matters: Engagement rate indicates how compelling the content was to the audience. A post with 500 likes might sound great, but if the influencer has 100,000 followers, that’s only a 0.5% engagement rate – below average. Conversely, 500 likes on an account of 5,000 followers is a 10% engagement rate – outstanding performance. Generally, most influencers have an engagement rate between 1% and 3%, so anything above ~3% is considered strong.  Micro-influencers often see even higher engagement; around 5%+ is a very good engagement rate for them . These benchmarks help you gauge if your campaign under- or overperformed typical norms. For instance, if your campaign posts achieved a 4% engagement rate on Instagram and the platform average is ~1.5% , your content did well in capturing attention.

Track not just the quantity but the quality of engagements. Comments can indicate deeper interest – read them to gauge sentiment. Shares and saves are strong endorsements; they mean people found the content valuable enough to pass along or revisit. If an influencer’s post about your product is getting shared widely, that expands reach exponentially and signals your message is hitting a nerve.

Benchmark: On Instagram, an average engagement rate across all influencers was about 1.6% in 2024. Aiming for ~3% or higher per post is a good benchmark for success, with micro-influencers often achieving higher engagement due to their niche, loyal following. Always compare against similar influencer tier and platform – e.g., TikTok typically sees higher engagement rates than Instagram for the same follower count.

3. Follower Growth and Brand Awareness Metrics

One way to measure brand awareness from an influencer campaign is to look at growth in your own social following and brand mentions during and after the campaign. If an influencer introduces your brand to new people, you’d hope to see some of those people follow your account, subscribe to your newsletter, or search for your brand online.

Follower growth on your social media is a telling metric here. For example, track how many new Instagram followers your store’s account gains during the campaign period. Many platforms’ analytics will even show you which specific post or mention drove new followers. If you see a spike in followers on the days an influencer posted about you, that’s a clear sign of increased awareness.

Similarly, track brand mentions or tagged posts. Some of the influencer’s audience might start talking about your product or sharing their own content about it. You can manually search hashtags/mentions or use social listening tools to quantify this.

Why it matters: These metrics show you if the influencer buzz translated into more people entering your brand’s orbit. If “increase brand awareness” was your goal, an uptick in followers or mentions is a concrete indicator of success. It’s essentially measuring how much your audience grew thanks to the campaign.

Note: It’s normal for follower growth to be relatively modest per campaign. However, those new followers are often highly interested leads since they came via a trusted recommendation. Over time, multiple influencer collaborations can steadily build a larger, engaged audience for your brand.

4. Click-Throughs and Traffic

For ecommerce sellers, one big reason to use influencers is to drive traffic to your store or product pages. Thus, click-through metrics are vital. This can include:

• Link clicks: How many people clicked the link in the influencer’s bio, swipe-up story, or affiliate link directing to your site.
  
• Swipe-ups or tap-throughs: For platforms like Instagram Stories or Snapchat where viewers can swipe to your content.
  
• Referral traffic: Visits to your website that came from the influencer’s posts. You can see these in Google Analytics under referral sources or by using UTM parameters.
  

Tracking clicks usually requires giving the influencer a trackable link or code. For example, generate a unique URL  for each influencer or campaign. Many small businesses use URL shorteners like Bit.ly or custom affiliate links to monitor clicks. If the influencer is on Instagram and you don’t have link features, you might rely on promo codes to entice users to visit and buy – you can track usage of that code on your site.

Why it matters: Clicks are the bridge between social media engagement and on-site action. A high number of clicks means the influencer’s content not only interested people, but compelled them to take the next step to learn more or shop. If you got 1,000 clicks but only 100 conversions, that might indicate a landing page or offer issue. If you got very few clicks relative to reach, perhaps the call-to-action in the influencer’s content wasn’t strong enough or the audience wasn’t motivated – an insight for future campaign messaging.

Action point: Set up Google Analytics  on your store if you haven’t already. It’s invaluable for seeing traffic spikes and sources. You can tag your influencer URLs with campaign identifiers to easily filter traffic and conversions from that campaign in GA.

5. Conversions and Sales

Ultimately, most ecommerce brands care about conversions – typically making a sale, but it could also be email sign-ups, app installs, etc., depending on your goal. Conversion metrics show the direct outcomes an influencer campaign produced.

Key conversion metrics include:

• Number of conversions attributed to the campaign.
  
• Conversion rate of the traffic coming from the influencer. For example, if 500 people clicked the link and 50 made a purchase, that’s a 10% conversion rate for that traffic segment.
  
• Total revenue generated from those conversions.
  

To attribute sales to an influencer, use unique tracking methods: promo codes, affiliate links, or dedicated landing pages for each influencer. Promo codes are easy to set up with most ecommerce platforms and let you track how many people used the influencer’s code at checkout. Affiliate or referral links that the influencer shares will log traffic and sales from their audience. Some brands also use cookies or pixel tracking to follow when a user coming from an influencer eventually purchases.

Why it matters: These metrics tie the campaign to tangible business outcomes. While likes and shares are nice, conversions are usually the ultimate goal – they show that the influencer marketing effort resulted in real customers and revenue. For example, if you spent $1,000 on a one-off post and it directly led to $3,000 in sales, that’s clearly a successful outcome in terms of sales . On the other hand, if an expensive campaign yielded few conversions, you may need to reassess the influencer’s fit or the offer you promoted.

Pro Tip: Don’t expect 100% of influencer-driven sales to be trackable. Some people will see an influencer post, Google your brand days later, and buy without using the special link or code. This is why measuring overall lift during the campaign period is also useful. Compare your baseline sales before, during, and after the campaign. If you see a notable jump in the campaign window, that indicates additional influence. Surveys can also help – ask new customers how they heard about you.

6. Engagement Quality & Sentiment 

Not every result is purely quantitative. Qualitative indicators of campaign success include the sentiment and content of engagement. Are people leaving positive comments? Is the overall tone indicating excitement about your brand? Did the influencer’s content generate discussion or user-generated content?

Brand sentiment analysis can be more advanced. But as a small business owner, simply reading through the comment threads and DMs can give you a feel for how the campaign was received. If you notice lots of enthusiasm, questions about your product, or statements like “I need this!” – those are great signs. If you see negative or confused reactions, that’s feedback to note and address in future marketing.

While harder to measure, sentiment is important for understanding the quality of influencer engagements, not just the quantity. A campaign might have moderate reach and conversions, but if it significantly improves how people perceive your brand, the long-term benefits can be large.

7. Cost Metrics: CPM, CPE, CPA

In addition to outcome metrics, consider tracking cost-related metrics to evaluate efficiency:

• CPM  – cost per 1,000 impressions. Calculate by:  × 1000. This lets you compare the cost efficiency to other advertising channels.
  
• CPE  – cost per like/comment/share. Calculate: total cost / total engagements. If you paid $500 for a post that got 5,000 engagements, your CPE is $0.10. This is useful for brand awareness campaigns where engagement is the primary desired outcome.
  
• CPA  – essentially the same as Cost per conversion or cost per customer acquired via the campaign. Calculate: total cost/number of conversions. If that $500 post yielded 25 purchases, CPA = $20 per acquired customer.
  

Why they matter: These KPIs help you judge the cost-effectiveness of the influencer campaign. For example, if your CPA via influencer is $20 and your average CPA via Facebook Ads is $30, the influencer partnership was a more efficient way to get a customer. On the flip side, a very high CPE or CPA might signal that this campaign or influencer was not a great investment relative to other options.

Keep these in perspective of value: a higher CPA might be acceptable if those customers have high lifetime value or if the campaign also boosted brand sentiment. But tracking cost metrics ensures you’re not paying disproportionate amounts for minimal results. It helps you refine your influencer selection and negotiation.

Summary of Key Metrics: Below is a quick reference table of the main influencer marketing KPIs and how to use them:

Metric	What It Measures	How to Track or Calculate	Benchmark / “Good” Value
Reach	Audience size exposed to content	Provided by platform analytics	No hard “good” number; higher is better for awareness. Compare reach vs. followers.
Impressions	Total views of content	Provided by platform analytics	Can be higher than reach. Indicates virality if much higher than follower count.
Engagements	Audience interactions with content	Count likes, comments, shares, saves, link clicks	Depends on follower count. Raw numbers are less important than rate. High comments/shares indicate strong interest.
Engagement Rate	Engagement relative to audience size	× 100	~1–3% average; >3% is strong . Micro influencers: ~5%+ is excellent.
Follower Growth	New followers/subscribers gained	Track your follower count before vs. after campaign	Any noticeable uptick during the campaign is positive. E.g. +5% followers in a week is great for a small brand.
Clicks/Traffic	Traffic driven to your site or landing page	Use unique UTM links, affiliate links, or promo code redemptions in Google Analytics or Shopify reports	Varies by reach and offer. Measure click-through rate. E.g. 1-2% CTR from an IG Story swipe-up is common.
Conversions	Desired actions taken	Track via unique coupon codes, affiliate dashboards, or GA goals completed	Ultimately I want this to meet your goal. Conversion rate of influencer-driven traffic can be compared to your overall site conversion rate.
ROI	Revenue return for the cost	÷ Cost) × 100%	Aim for positive ROI. Many brands average ~5:1 to 6:1 ROI in influencer marketing. A campaign with ROI > 0%  might be acceptable if it has other benefits – but the higher, the better.
CPA	Cost to acquire one customer	Cost ÷ number of conversions	Compared to your typical CPA. If influencer CPA is lower, it’s cost-effective. If higher, evaluate why.

Use this table as a cheat sheet when reviewing your campaign results.

Calculating Influencer Marketing ROI

Return on Investment  is the north-star metric for many marketers because it directly answers “Was it worth it financially?” However, measuring the exact ROI of influencer marketing can be tricky. Unlike a pure ad campaign, an influencer’s impact might extend beyond immediate sales. Still, it’s important to crunch the numbers and see the direct return whenever possible.

The basic formula for ROI in marketing is:

∗∗ROI**ROI%** = \frac{\text{Net Profit}}{\text{Cost of Campaign}} \times 100

Where Net Profit = Revenue from the campaign − Cost of the campaign. For example, if you spent $1,000 on an influencer campaign  and it led to $3,000 in sales, the net profit is $2,000 and ROI =  × 100 = 200%. In other words, you earned $3 for every $1 spent, which is a 200% return.

Attributing Revenue: To measure revenue from the campaign, sum up all conversions you can attribute to the influencer’s efforts. This could be sales tracked via the influencer’s referral link, purchases using their promo code, or sales during the campaign window that you reasonably know came from the influencer’s audience.

Remember to account for all costs as well. Campaign cost isn’t just what you paid the influencer; include any free products you gave, shipping costs for those products, commissions on affiliate sales, and even the value of discounts offered. Also factor in any spend on content production if you, say, hired a photographer to help or boosted the influencer’s post with ad spend.

Once you have total revenue and total cost, plug into the formula. A positive ROI  means you earned more than you spent. If ROI is 100%, that means you doubled your money. An ROI of -100% would mean you earned nothing and lost your entire investment.

Many marketers find direct attribution ROI is not always huge for influencer campaigns, especially one-off collaborations. Perhaps you spent $500 and made $600 in immediate sales – that’s a +20% ROI, not very high compared to some channels. But don’t panic – influencer marketing also provides value in content creation, brand exposure, and long-tail sales that might occur later. As the Ahrefs marketing team notes, it’s not always easy to measure absolute ROI of influencer campaigns, but you can measure relative ROI by focusing on the KPIs tied to your goals . In practice, that means even if the dollars don’t fully add up today, track those intermediate metrics  that have future value.

Interpreting ROI: If your influencer campaign ROI is, say, 50%, what does that mean? It means for every $1 spent, you got $1.50 back. Whether that’s “good” depends on your goals and what the ROI would look like elsewhere. Compare it to your other marketing activities – if your email marketing typically has 300% ROI and this influencer campaign had 50%, the campaign wasn’t as cost-effective in pure sales terms. However, if that influencer content can be reused or if it brought you new customers who will buy again, the overall value may be higher.

Also consider incremental lift. Sometimes influencers help expand your audience or build social proof, which indirectly increases ROI over time. It’s wise to track those new customers acquired – do they have a higher lifetime value? Do they refer to friends? Such downstream effects won’t show up in a simple ROI formula immediately, but they’re part of the big picture.

If calculating ROI feels daunting, break it down:

• Determine the KPIs that feed into sales.
  
• Gather the costs related to the campaign.
  
• Use tools or spreadsheets to attribute sales and sum costs.
  
• Then do the math for ROI.
  

The more you do this, the easier it gets to forecast ROI before you even run a campaign. For example, you might predict: “If this influencer can drive 1,000 clicks and I expect a 2% conversion rate at a $50 average order, that’s 20 sales × $50 = $1,000 revenue. If the collab fee is $300 and product cost is $200, ROI would be /$500)*100 = 100%.” You can play with those numbers to see if an influencer is likely to be profitable before you commit.

Remember: ROI is important, but it’s not the only measure of success. Especially for small businesses, building brand awareness and customer relationships can be just as valuable early on. Don’t kill a campaign just because the first outing didn’t make a profit. Look at all the metrics in context. Maybe the ROI was slightly negative, but you gained 500 new Instagram followers and lots of UGC  – those are assets that can lead to future ROI. Adjust your strategy and see if you can improve results in the next round.

Using Benchmarks to Gauge Performance

We’ve mentioned a few influencer marketing benchmarks above, but let’s consolidate some common points of reference. Benchmarks give you a frame of reference to interpret your metrics – they help answer “is this number good or bad?”.

• Engagement Rate Benchmarks: As noted, an average engagement rate on Instagram is around 1–3%. Influencers with highly engaged audiences can often hit 3–5%. Nano-influencers  and micro-influencers often see higher rates; for example, nano influencers  might see engagement rates around 5% or more, while mega influencers  might be under 1%. If your campaign posts exceeded the 3% mark, that’s generally a success on engagement. If they were below 1%, it could indicate content that didn’t resonate or an influencer whose followers aren’t that engaged.
  
• Reach Benchmarks: Organic reach on platforms like Instagram is typically a fraction of an influencer’s follower count due to algorithmic feeds. A very roughly expected reach might be 10-30% of followers on Instagram. On TikTok, reach can exceed follower count if content goes viral . So if an IG influencer with 100k followers delivered 20k reach for your post, that 20% is quite decent. If it was 5k , that’s below par – perhaps the post was made at a bad time or didn’t get picked up by the algorithm. Benchmark your reach percentage against the influencer’s averages too – many influencers will share their average story views or post reach with you if asked. Ensure your campaign post is in line with their norms; if not, debrief with the influencer to hypothesize why.
  
• Click-Through Rates: These can vary widely by platform. On Instagram, a 1% swipe-up rate on Stories was once considered standard, but with link stickers now, you might see anywhere from 0.5%–5% depending on how interested the audience is and how compelling the call-to-action is. On emails a 2-3% click rate is normal. So if 100,000 saw an influencer’s TikTok and 2,000 clicked the bio link , you did fairly well. If only 50 clicked , something didn’t connect – either the landing page wasn’t enticing or the offer was weak. Benchmark tip: Don’t just look at percent; consider absolute numbers relative to your business. If an influencer only got 100 clicks but those 100 people were super relevant and 10 bought, that’s better than 1,000 random clicks with 5 purchases.
  
• Conversion Rate: If you have data on your site’s usual conversion rate , use that as a benchmark. Traffic from influencer campaigns could convert higher if it’s very targeted and warmed up by the influencer’s endorsement, or sometimes lower if the traffic is more top-of-funnel . Suppose your average site conversion is 2% and the influencer’s referred traffic converted at 4% – that’s a strong result, showing the leads were high quality. If it converted at 0.5%, the campaign might have driven a lot of window-shoppers who didn’t buy. Industry-wide conversion benchmarks for influencer traffic aren’t well published, since it varies by product and influencer-type, but aim for equal or better than your other channels. Also compare conversion rates between influencers if you ran multiple campaigns; this can reveal who drove more ready-to-buy traffic.
  
• ROI Benchmarks: A widely cited stat  is an average of ~$5 return per $1 spent  in influencer marketing . Top brands even see up to $18 per $1 on some campaigns . If your campaign ROI was, say, 300%, it might sound low compared to that $5:$1 ideal, but consider your scale and maturity. Smaller brands or first-time campaigns might not hit that immediately. The trend of your ROI is what to watch: if your first campaign is -50% , your second is breakeven, and third is +50%, you’re moving in the right direction as you optimize creative and influencer selection. Over time, aim to approach or exceed that industry average ROI. Also, consider non-financial returns: content assets, new followers, etc., which have their own ROI if you monetize them.
  
• Engagement Benchmarks by Platform: Note that what’s “good” can vary by platform. For instance, TikTok engagement  tends to be higher percentage-wise than Instagram. Twitter  engagement might be lower typically. So calibrate your expectations based on platform norms. A 10% engagement rate on TikTok might be equivalent in success to a 3% rate on IG. If possible, gather benchmark data per platform or ask the influencer for their own average metrics as a baseline.
  

In summary, use benchmarks as a guide, not a strict pass/fail. They help you identify where you excel  and where you might need improvement . Over time, as you run more campaigns, create your own benchmarks too. You’ll learn what numbers are typical for your brand’s influencer efforts, which is ultimately the most relevant benchmark.

Influencer Reporting Tools and Analytics Platforms

Measuring influencer marketing performance can be time-consuming if you try to do it all manually. The good news is there are many influencer marketing analytics and reporting tools to make your life easier. These range from built-in platform insights to dedicated software solutions. Here are some tools and methods to consider:

• Social Media Platform Analytics: The first place to get data is from the social platforms themselves. Instagram, Facebook, Twitter, YouTube, TikTok – all offer native analytics for business accounts. Your influencers can usually access these for their posts and share screenshots or reports with you. For example, Instagram Insights will show reach, impressions, profile visits, and interactions for each post or story. You can ask influencers to send you these stats for their content featuring your brand. These native tools are free and provide the most direct data on reach and engagement.
  
• Google Analytics : As mentioned, GA is invaluable for tracking any traffic and conversions on your own website. By setting up UTM parameters for influencer links, you can see exactly how many visitors and purchases came from each influencer or campaign. GA will also allow you to see metrics like bounce rate and time on site for influencer-referred visitors – useful for understanding how engaged that traffic is once on your store. If you run an online store, make sure to set up Google Analytics goals or e-commerce tracking so that conversions and revenue are recorded. This way, when you log in to GA, you can quickly pull a report like “show revenue by campaign source” and isolate each influencer’s contribution.
  
• Influencer Marketing Platforms: These are specialized tools or software that streamline influencer campaigns from discovery to tracking. Examples include GRIN, Upfluence, Aspire , Tribe Dynamics, Klear, and Incense. Such platforms often let you find influencers, manage contracts, and automatically collect performance data. They provide dashboards where you can see metrics like engagement, clicks, conversions per influencer in one place. If you plan to do influencer marketing at scale, investing in a platform can save a ton of time. They often have built-in reporting templates and even ROI calculators. For instance, GRIN touts automated data collection so you get all the metrics in real time for each influencer. These tools are usually paid, so they make the most sense if influencer marketing is a significant part of your strategy.
  
• Affiliate Tracking Software: If you work with influencers on an affiliate or commission basis, you might use affiliate tracking software. These tools generate unique referral links or coupon codes for each influencer and automatically track clicks and sales. They often have dashboards where both you and the influencer can log in to see performance stats. This doubles as a reporting tool so you don’t have to manually calculate anything. Many ecommerce platforms  have plugins for affiliate tracking which can simplify measuring ROI per influencer.
  
• Spreadsheet + Manual Reporting: For a very small scale, you might track metrics in a simple spreadsheet. Create a sheet with columns for reach, likes, comments, new followers, clicks, sales, etc., and fill it in with data the influencer provides and what you see in Google Analytics. This can be a low-tech but effective “tool.” Over time, your spreadsheet becomes a record of all past campaigns to analyze. You might find it useful to add a column for notes/insights so you remember context.
  
• Social Listening and Brand Monitoring Tools: To capture those harder-to-measure things like sentiment and mentions, consider tools like Brand24, Mention, Sprout Social, or Hootsuite. Some of these allow you to input your brand name or campaign hashtag and will collect all mentions across social media. They might not directly tie a mention to a specific influencer campaign, but if you run a big campaign, you can observe spikes in mention volume or see the conversation it generated. These tools often provide sentiment analysis as well. For a small business, manual monitoring might suffice until volume grows, given these tools often come with a price tag. But many offer free trials or basic free plans you can experiment with during a campaign to gauge their usefulness.
  
• Influencer Reporting Templates: If you prefer a more guided approach, you can find reporting templates online – for example, an Excel or Google Sheets template where you just plug in numbers and it generates charts. Some marketing blogs and agencies share such templates for measuring influencer campaigns. Using a template ensures you don’t forget any key metrics when reporting.
  
• Ahrefs Tools for Indirect Impact: Beyond typical social and sales metrics, you might be interested in the broader impact of influencer marketing on your brand’s online presence. For instance, if an influencer campaign increases searches for your brand or product, you could detect that via SEO tools. An SEO tool like Ahrefs’ Keywords Explorer can help you see if your branded search volume went up during the campaign or if backlinks were created. While this is not a primary influencer metric, it’s part of the holistic view of performance. Using a tool like Keywords Explorer can reveal these secondary effects – e.g., an increase in people searching for “[YourBrand] reviews” after a big YouTube influencer mentioned you, indicating their audience is moving down the purchase consideration funnel.
  

In short, leverage technology to make tracking easier. Even if you start scrappy, as your influencer marketing grows, integrate more robust influencer reporting tools. They will save you time and provide professional-looking reports you can share with your team or investors. Plus, some platforms will aggregate industry data and influencer marketing benchmarks, giving you insight into how your campaigns stack up against others in your niche.

Lastly, always export and archive the data from each campaign. Whether it’s screenshots from Instagram Insights or a PDF report from your influencer platform, save it. Historical data is gold for refining your strategy. Over time, you’ll be able to identify trends like which influencer type yields the best ROI for you, which platform drives the most engagement, what posting schedule works best, etc. All of that comes from measured results.

Putting It All Together: Analyze and Improve

Measuring success isn’t just about gathering numbers – it’s about analyzing them and then taking action. After each influencer campaign, do a mini post-mortem:

1. Compare results to goals: Did you meet the goals you set? If you wanted 100 email sign-ups but got 50, dig into why. Perhaps the incentive wasn’t strong enough or the influencer’s audience wasn’t the perfect fit. If you exceed the goal, celebrate and identify what contributed.
   
2. Look at the full funnel: For example, maybe you reached a lot of people, they engaged moderately , many clicked, but few converted to sales. That points to a possible issue on the landing page or with the offer. Or maybe engagement was low but those who did engage converted at a high rate – meaning the content appealed strongly to a smaller segment of the audience. These funnel insights help you tweak the next campaign’s content or targeting.
   
3. Get influencer feedback: The influencer might have insights from their perspective. They have a pulse on their audience – perhaps they noticed people DMing them for a coupon or asking questions. Discuss what went well and what didn’t. This can uncover qualitative feedback that data alone won’t show.
   
4. Benchmark against other campaigns: If this isn’t your first rodeo, compare the metrics to previous influencer campaigns. Are your key metrics trending up, indicating you’re improving content and influencer selection? For instance, maybe last campaign had 2% engagement and this one hit 3% – what changed? Did you use a more niche influencer or provide a better creative brief? Continuously optimize based on past learnings.
   
5. Consider the broader marketing mix: Evaluate how the influencer campaign contributed to your overall marketing goals. Maybe it didn’t generate a ton of immediate sales, but you notice that other channels performed better during the campaign. Influencer marketing shouldn’t exist in a silo. It often works in tandem with other efforts. For example, an influencer might introduce new people to your brand who then sign up for your newsletter, and later your email converts them. In this case, the influencer was the top-of-funnel driver, even if the last-click attribution might go to email. Recognize those indirect effects.
   
6. Document benchmarks and insights: Write down what you consider a successful metric for next time . These become your new targets. Also note any benchmark deviations – maybe you learned that for YouTube influencers, a 1% click-through is actually good because people often watch and then search later instead of clicking immediately. So your benchmarks might be platform-specific.
   
7. Refine your influencer strategy: Use performance data to inform your next moves. If one influencer drove great ROI, consider an extended partnership or affiliate arrangement with them. If another underperformed, you might try a different influencer or platform next time. Also, metrics can guide finding the right influencers: for example, if you see micro-influencers are consistently delivering better engagement and ROI than a celebrity influencer you tried, you’ll focus on micro-influencers moving forward – quality over quantity in audience size.
   

In measuring influencer marketing, consistency is key. Make measurement an integral part of every campaign, not an afterthought. Over time, you’ll build a robust analytics approach that takes the guesswork out of influencer collaborations. As one influencer marketing guide notes, “You’ll need to know your objectives in order to measure if your campaign is successful… KPIs allow you to measure progress towards your objectives”.
