Definition: A collab post is a single Instagram post or reel co-authored by two or more accounts, which appears on every collaborator’s profile and is shown to each of their audiences.
Also called: Instagram Collab, collaborative post, co-authored post

The account that creates the post invites one or more collaborators while publishing. Once a collaborator accepts, Meta says the content reaches each collaborator’s audience and appears on each account’s profile grid. It is one post shown on several profiles, not separate copies, and every author’s name appears in its header.
Instagram supports collabs on feed posts, carousels and reels. Per Meta, a private account can invite a collaborator only if that person follows it back. The number of collaborators allowed has changed over time, so check the invite screen in the app for the current limit.
Collabs suit any post that genuinely belongs to two accounts: a joint event, a product made together, a guest tutorial, or a creator partnership. Both audiences see the same post, so a smaller account gets in front of a larger one without a separate repost.
Because the post sits on both profiles, agree before posting who reports on it and which numbers you will compare. Track reach and new followers in the days after the post on each account, and compare the collab’s engagement rate with each account’s usual posts.
A local coffee roaster and a bakery post a collab reel about their new pastry pairing. The bakery creates the reel and invites the roaster, who accepts. The reel appears on both grids, and the roaster sees a jump in profile visits from the bakery’s followers that week.
Influencer marketing is a brand partnering with creators, by paying them or giving them products, to promote the brand to the creator’s own audience in the creator’s own voice.
User-generated content (UGC) is any content about a brand made by people outside it, such as customers’ photos, videos, reviews and posts, rather than by the brand itself.
Reels are short, vertical, full-screen videos on Instagram and Facebook that play with sound and are recommended to people who do not follow the account, as well as to followers.
Organic reach is the number of unique people who saw a post or account through unpaid distribution (feeds, search, shares and recommendations), excluding anyone reached through ads.
Engagement rate is the percentage of people who interacted with a post (liked, commented, shared, saved or clicked) out of the people who saw it or follow the account.
