Placement asset customisation is an option in Meta Ads Manager that lets a single ad show different media, and sometimes different text, depending on where it appears. You might give feeds a 4:5 image, Stories and Reels a 9:16 video, and the right column a landscape crop, all inside one ad with one set of results.
How placement asset customisation works
When an ad set uses several placements, the ad-level media section lets you choose whether to use the same media everywhere or to customise by placement group. Ads Manager groups placements broadly into feeds, Stories and Reels, in-stream video, search results, messages, apps and sites, and the right column. You upload a version for each group you want to control, and any group you leave alone uses the default asset, cropped by Meta.
At the time of writing (October 2026), the option is available for single image and single video ads and, in a more limited form, for some other formats; it is not offered with every creative set-up. In some placement groups you can also change the primary text or headline, for example a shorter line for Stories where long copy crowds the screen. Meta may also apply automatic adjustments under Advantage+ creative, so check which enhancements are switched on so you know what is your asset and what is Meta’s crop.
Because it is still one ad, reporting stays in one place. A placement breakdown shows how each version performed.
Why it matters
Vertical placements are a large share of the inventory on Facebook and Instagram, and an ad that looks native in each spot generally holds attention better than a square image floating in a black frame. For a small UK business with a limited budget, this is one of the cheapest ways to improve creative quality: the message stays the same, only the shape changes.
It also keeps the account simple. Without it, people often create separate ad sets for feeds and for Stories, which splits the budget and slows learning.
There are cases where it adds little. If an ad set runs in feeds only, one well-made 4:5 asset is enough. If you rely on a catalogue or flexible format that assembles creative automatically, you control the inputs rather than each placement’s version, so the effort is better spent supplying good source images in several ratios.
Common mistakes
- Uploading one square asset and letting Meta crop it for every placement, which can cut off faces, logos or prices.
- Ignoring the safe zone in vertical versions So captions or offers sit under the profile name or call-to-action button.
- Telling different stories in different versions. If the feed image promotes one offer and the Reel another, the ad’s results become impossible to interpret.
- Customising placements you have excluded Which is wasted effort, or forgetting placements you left switched on.
How to act on it
Plan each creative in at least two shapes from the start: 4:5 (or 1:1) for feeds and 9:16 for Stories and Reels. Build vertical-first creative when video is involved, because cropping a landscape video down rarely works. Keep the same offer, wording and branding across versions.
Before publishing, open the ad preview for each placement group and check text, faces and buttons are visible. After a week or two, review results by placement and replace any version that clearly lags. Producing placement-ready video and image sets is part of my Facebook video, Reels and Stories ads service.
