What exactly is a post ID?

Every Facebook post, including ad posts, has a unique identifier called a post ID. When you create a new ad, Meta generates a new post and a new ID. Post ID duplication reuses the original post, carrying all engagement forward.

Will this work if the original ad is paused?

Yes. The post ID exists independently of whether the ad is active or paused. You can duplicate from paused ads and the engagement will still carry over.

Can I duplicate across different ad accounts?

Post ID duplication works within the same ad account and page. Cross-account duplication requires additional steps since the post is tied to a specific Facebook page.

Does this affect the original ad?

Not at all. The original ad continues running exactly as before. The duplicated ad simply references the same underlying post, so engagement is shared between both.

Duplicate Ads Without Losing Social Proof

When you duplicate a Facebook ad the normal way, you lose all the likes, comments, and shares. Adship preserves the original post ID so your new ads carry forward every piece of social proof.

The Problem

Standard Ad Duplication Resets All Social Proof to Zero

You have an ad with 500 likes, 80 comments, and 120 shares. You want to test it with a new audience or in a new campaign. You duplicate it in Ads Manager and the new ad shows zero engagement. All that social proof, the trust signals that make people stop scrolling and actually click, is gone. Ads with visible social proof consistently outperform identical ads without it. Higher engagement signals credibility, which improves CTR and lowers CPA.

The Solution

Reuse the Original Post ID Across New Ad Sets

Adship duplicates your ads using the original post ID instead of creating a new post. This means the new ad references the exact same Facebook post, so all existing likes, comments, and shares appear on the duplicated ad. You can move winning ads into new campaigns, test new audiences, or restructure your account, all without sacrificing the social proof that took weeks to build.
