Meta Ads: does leaving primary text/headline blank in placement customizations actually fall back to the main text?
One ad, video customized per placement group (Feeds, Stories, Reels, In-stream ads for videos and reels, Status, Search results, Right column) so the crops fit. Ads Manager copies primary text and headline into each group as separate fields.
Later we updated the ad copy. Edited the main text, saved. But every customized placement group silently kept the old text, so the outdated version kept showing. I had to edit every group individually.
Meta's AI support says: leave the text fields in the placement customizations empty and they fall back to the main text. I can't find that documented anywhere (in the API each placement text is its own asset, a fork with no merge back).
- Has anyone verified the blank-field fallback actually works?
- Can you customize media only per placement while text stays controlled in one place?
- Or is the answer "duplicate the ad and never touch text fields in placement groups"?
(Advantage+ creative enhancements already checked.)
Thanks in advance!
