Last updated:
Google Search and other revenue hit $63.3 billion in Q2 2026, up about 17% from $54.2 billion a year earlier, per Alphabet’s Q2 2026 results. More advertisers are bidding on the same shoppers, and Shopping and Performance Max now decide a big share of where that money goes.
For a Shopify store, that makes the agency choice more expensive to get wrong. A strong Google partner fixes your product feed, splits brand from non-brand, and tells you what Performance Max is actually buying. A weak one hands you a blended ROAS and a monthly invoice. This list covers 10 Google Ads and PPC agencies worth a call, what each is built for, and what to ask before you sign.
TL;DR
- Google Search ad revenue grew about 17% year over year in Q2 2026, so competition for Shopify shoppers keeps rising.
- For eCommerce, the product feed and Merchant Center matter as much as keywords.
- Always ask an agency to split brand from non-brand search and to show what Performance Max spends on.
- In our pooled 2026 DTC data, median Google Ads ROAS was 4.07 across 19 stores. Use that as a sanity check, not a promise.
What does a Google Ads agency do for a Shopify store?
It connects your Shopify catalog to Google Merchant Center, cleans up the product feed, and runs Search, Shopping, Performance Max and YouTube campaigns. A good one separates branded from non-branded search, manages negative keywords, and reports on new-customer revenue, not just blended ROAS.
How much does a Shopify PPC agency cost?
Most eCommerce Google Ads agencies charge a monthly retainer, a percentage of ad spend, or both. Top Growth Marketing starts at $5,000 a month, month-to-month. Many agencies on this list don’t publish pricing, so ask for a written quote at your current spend level.
What is a good Google Ads ROAS for a Shopify store?
In Top Growth Marketing’s pooled 2026 data across 19 DTC stores, median Google Ads ROAS was 4.07, higher than Meta’s 2.70 because Google captures existing demand. Branded search inflates that number, so judge non-brand ROAS separately.
What to Look For in a Google Ads Agency for Shopify
Google Ads for eCommerce is different from lead generation. Most of the spend runs through Shopping and Performance Max, and both are driven by your product feed. Check these before anything else:
- Feed and Merchant Center work. Titles, product types, custom labels and disapproval fixes. If the agency doesn’t talk about the feed in the first call, it will treat Shopping like search.
- Brand vs non-brand split. Branded search looks great and would often convert anyway. Ask for ROAS and new-customer rate on non-brand campaigns only.
- Performance Max transparency. Ask how they see which channels, search terms and products PMax spends on, and how they keep it from cannibalizing branded search.
- Negative keywords and search terms. Weekly search-term reviews and a maintained negative list. Our guide to negative keywords covers what that looks like.
- Measurement past the platform. Google’s own numbers overlap with Meta and email. The agency should report against Shopify revenue or a blended MER.

How Much Does a Google Ads Agency Cost for a Shopify Store?
Pricing is less published in this category than in TikTok Shop. The common models are a flat monthly retainer, a percentage of ad spend, or a retainer with a percentage on top once spend crosses a threshold. Top Growth Marketing starts at $5,000 a month, month-to-month, with a first-month money-back guarantee. 20North Marketing’s contact form starts its budget options at $5,000 a month. Most others quote after a call.
Compare quotes at your real spend level. A 10% fee looks cheap at $20,000 a month in spend and expensive at $200,000. And ask what’s included: feed management, landing page testing and YouTube creative are often extra.

| ✅ Do | ❌ Don't |
|---|---|
| Ask for non-brand ROAS and new-customer rate | Accept a blended ROAS inflated by branded search |
| Audit the product feed before scaling spend | Scale Shopping or PMax on messy titles and missing attributes |
| Keep brand search in its own campaign | Let Performance Max quietly absorb your brand traffic |
| Review search terms and negatives weekly | Set negatives once and forget them |
| Report against Shopify revenue or MER | Judge the agency only on Google’s own conversion numbers |
The TGM Take
Most Shopify brands that feel their Google Ads have “stopped working” don’t have a bidding problem. They have a Performance Max campaign quietly buying their own branded searches, reporting a great ROAS, while non-brand growth flattens. It looks fine in Google Ads and shows up as flat new-customer revenue in Shopify.
Before you pick an agency, ask each one to split your last 90 days into brand and non-brand. The one that shows you that split without being asked is usually the one worth hiring.

Frequently Asked Questions
What is the best Google Ads agency for Shopify stores?
It depends on your size. Brands at $100K–$25M a year that want Google run with Meta and email usually fit a full-funnel team like Top Growth Marketing. Brands that want a large Google-first specialist fit Logical Position or Disruptive Advertising, and enterprise brands with Amazon and retail media fit Tinuiti or Wpromote.
How much does a Shopify PPC agency cost?
Top Growth Marketing starts at $5,000 a month, month-to-month. Most other agencies on this list quote after a call, using a flat retainer, a percentage of ad spend, or both. Always compare quotes at your actual monthly spend.
Is Performance Max good for Shopify stores?
It can be, if your product feed is clean and branded search is kept separate. Without those controls, Performance Max often spends on branded searches you would have won anyway, which inflates ROAS without adding new customers.
What ROAS should a Shopify store expect from Google Ads?
In Top Growth Marketing’s pooled 2026 data across 19 DTC stores, median Google Ads ROAS was 4.07. Treat branded and non-branded ROAS separately, since branded search usually runs far higher.
Should I hire a Google Ads agency or a freelancer?
A strong freelancer can work at lower spend if the account is simple. Once you run Search, Shopping, Performance Max and YouTube together, need feed work, or spend well into five figures a month, an agency’s wider team usually pays for itself.
