TL;DR
- Facebook Dark Posts (now called 'unpublished posts') let you run highly targeted ads to specific audiences without the post appearing on your public Page—making them essential for A/B testing creative, targeting different customer segments with tailored messaging, and keeping your feed clean.
- In Wpromote's tests across three ad accounts, one dark post reused across ad sets averaged a 43% higher click-through rate and a 30% lower cost per acquisition than standard ads.
What are Facebook dark posts?
Dark posts are ads created inside Meta Ads Manager that do not appear on your organic page feed - they only show to targeted audiences. They are now the standard for paid ads, letting brands run dozens of creative variations without flooding their page.
Why use Facebook dark posts?
Dark posts let you A/B test creative, copy, and audiences without cluttering your organic page or confusing followers. Reusing one dark post across ad sets also keeps its likes and comments in one place, which is where most of the performance gain comes from.
How do you create a Facebook dark post?
Inside Ads Manager, build a new ad with creative and copy, choose an objective, and select 'Use Existing Post' or 'Create New Ad' - if you create new, the post will not appear on your page. You can also use Page Posts > Create Post in Page Posts to draft a dark post for later use.
A dark post is a Facebook or Instagram ad that never appears on your Page’s public feed. Only the people you target in Ads Manager see it, and Meta officially calls it an unpublished Page post. Every ad you build in Ads Manager is technically one.
What makes dark posts useful is the post ID. Run the same post across several ad sets and every like, comment and share lands on one post, so the social proof builds instead of starting from zero each time you duplicate an ad.
This guide covers what dark posts are, how they compare with boosted posts and standard ads, how to create one step by step, and the process we use to scale them.
What Is a Dark Post?
A dark post is an unpublished Page post used as an ad: it carries your Page’s name and looks like a normal post in the feed, but it is not shown on your Page, so only the audience you target ever sees it. Wpromote notes that “unpublished page posts” is the name Facebook uses for them.
Dark posting is the practice of building ads this way on purpose: writing ads that only make sense for one audience, testing several versions side by side, and reusing the winning post across campaigns.
Dark Posts vs Boosted Posts vs Standard Ads
| Boosted post | Standard Ads Manager ad | Reused dark post | |
|---|---|---|---|
| Shows on your Page | Yes | No | No |
| Where it is built | Page or Meta Business Suite | Ads Manager | Ads Manager, using an existing post ID |
| Likes and comments | Shared with the organic post | Split across every duplicate | Collected on one post across all ad sets |
| Best for | Amplifying a post that already works organically | Testing new creative | Scaling a proven ad |
Which Ad Types Cannot Be Dark Posts?
Collection ads and dynamic catalog ads cannot be turned into a reusable dark post, because their content is assembled per person instead of fixed. Single image, video and carousel ads work.
Why Use Facebook Dark Posts?
Use dark posts to keep social proof in one place while you scale. In Wpromote’s tests across three ad accounts, a manual dark post reused across ad sets averaged a 43% higher click-through rate, a 22% higher conversion rate, a 15% lower cost per click and a 30% lower cost per acquisition than standard ads, which each create their own post.
In money terms, a 30% lower CPA turns a $40 cost per purchase into $28 ($40 × 0.70), so the same $2,800 buys 100 purchases instead of 70.
- Social proof: comments and reactions pile up on one post instead of being split across duplicates.
- Testing: run several versions of an ad to different audiences without any of them appearing on your Page.
- Segment offers: show a returning-customer discount or a regional promotion only to the people it is meant for.
- A clean Page: your organic feed stays focused on content, not twenty variations of one ad.
Meta has added options to carry engagement over when you duplicate an ad, but in our accounts the post ID method is still the reliable way to keep it. For more on why engagement matters, see our guide to social validation.
How to Create a Facebook Dark Post, Step by Step
To create a reusable Facebook dark post, publish an ad once, copy its post ID, then build every other ad from that existing post. The screenshots below are from an earlier version of Ads Manager; the option names are the same.
Step 1: Create Your Ad
Build the ad in Ads Manager as normal: creative, primary text, headline and call to action. Use the version that has already won your creative test.
Step 2: Publish the Ad
Publish it so Meta creates the unpublished post behind it. The post exists from this point, even though it never appears on your Page.
Step 3: Open the Post
From the ad preview, open the option to view the Facebook post with comments. This opens the dark post itself.
Step 4: Copy the Post ID
The post ID is the long number in the post’s URL. Copy it, or copy it from the ad preview details if your Ads Manager view shows it.
Step 5: Switch the Next Ad to an Existing Post
In the next ad set, create an ad and choose Use existing post instead of building new creative.
Step 6: Enter the Post ID
Choose to enter a post ID and paste the number you copied. The preview should show the same post, with its likes and comments.
Step 7: Check the Dark Post
Confirm the preview matches the original ad, including the destination URL and the tracking settings, then publish.
Step 8: Scale Across Ad Sets and Campaigns
Repeat steps 5 to 7 in every ad set and campaign where you want the ad to run. All of them now feed one post, so its social proof keeps growing.

Over years of client spend, reusing a proven dark post has beaten duplicating ads in our accounts, because the engagement keeps building on one post.
Only turn your best ads into reusable dark posts. That way every dollar you scale goes behind creative that has already proven itself.
The Dark Post Building Process
We usually follow this process when building dark posts:
- Research customer and product
- Build an avatar (goals, fears, features & benefits)
- Write 2-3 copy variations (using different hooks and offers)
- Create 2-3 image and video variations
- Run all variations as individual ads or with dynamic creative
- Conclude the top copy and creative
- Make the Facebook dark post
- Scale across other ad sets and campaigns.

How Much Do Dark Posts Outperform Regular Facebook Ads?
A reused dark post outperforms standard ads that each create their own post. In Wpromote’s manual dark-post tests across three client ad accounts, dark posts averaged a 43% higher click-through rate and a 30% lower cost per acquisition than standard ads.
Wpromote puts the gap down to engagement: one post collects every like and comment, and that social proof makes the next person more likely to click. Its results are from three accounts, so treat them as a direction to test rather than a guarantee.
Frequently Asked Questions
What is a Facebook Dark Post?
A Facebook Dark Post (officially called an unpublished post or page post ad) is an ad that looks like a regular Page post but never appears on your public Timeline. It's visible only to the targeted audience you specify in Ads Manager.
How do Dark Posts differ from regular Facebook ads?
Regular boosted posts show on your public Page, while dark posts are invisible to anyone not in your target audience. This lets you run multiple versions of the same message to different audiences simultaneously without cluttering your Page.
What are the main use cases for Facebook Dark Posts?
Dark posts are ideal for A/B testing ad creative, targeting different customer segments with tailored copy, running regional promotions, testing messaging before publishing to your full Page, and separating retargeting ads from prospecting content.
How do I create a Facebook Dark Post?
In Meta Ads Manager, create a new ad and select 'Use Existing Post' or create a new post within the ad creation flow. Ensure the post is set as 'Unpublished' in Page settings or created directly inside Ads Manager so it never appears on your Page.
Are Facebook Dark Posts still relevant after iOS 14?
Yes. Dark posts remain useful for testing creative and targeting regardless of iOS privacy changes, and they are particularly useful for running segment-specific offers without broadcasting them to your full audience.
How many dark post variations should I test at once?
Test 2–4 variations at a time with equal budgets. Too many variations split your budget too thin to reach statistical significance quickly. Once a winner emerges, pause losers and build new tests from the winning creative.
How much better do dark posts perform than regular Facebook ads?
In Wpromote's tests across three client ad accounts, a manual dark post reused across ad sets averaged a 43% higher click-through rate and a 30% lower cost per acquisition than standard ads that each create their own post. The gain comes mostly from social proof building on one post.
Do dark posts work on Instagram too?
Yes. The same unpublished-post mechanism runs through Meta Ads Manager for both Facebook and Instagram, since Meta manages ad delivery for both from the same interface. The post never appears on either profile's public feed, only in the targeted audience's feed as a sponsored placement.
What is dark posting?
Dark posting is running ads as unpublished Page posts that only the targeted audience sees. Marketers use it to test several versions of an ad, show offers to specific segments, and reuse one proven post across ad sets so its likes and comments keep building.
How do I reuse a dark post across ad sets?
Publish the ad once, open the post and copy its post ID, then in each new ad choose Use existing post and enter that ID. Every ad set then runs the same post, so engagement collects in one place.

Hi, I just have a question I made an engagement ad (for likes on the webpage) now when I try to bring social proof to my new conversion add it’s not allowing me, facebook disable the fact I want to change it to conversion.
Is there any way to solve it? Thanks
So you can’t use your dark post from an engagement campaign to a conversion campaign? You can always make the dark post in a conversion campaign then add that dark post to an engagement campaign.
The author did a fantastic job of explaining what dark posts are, how they can be used effectively in Facebook advertising, and the benefits they can bring to a business. The article is well-structured, easy to understand, and includes useful examples to help illustrate the points being made.
