Captions are the text creators publish with Instagram photos or videos, and keywords are relevant words in that text that help match posts to searches.12 Creators can edit captions after publishing, but Mosseri says Instagram looks at the caption written when a post is first published to understand an account for account searches.34 Viewers can filter suggested posts by words or hashtags in their captions, with hashtags requiring an exact match; these filters do not cover comments, posts from followed accounts, or suggestions viewed on instagram.com.5 Meta’s Newsroom says writers of potentially offensive Feed captions receive a warning that their wording resembles captions reported for bullying, giving them a chance to reconsider before posting.6 In August 2022, Instagram for Creators advised putting relevant keywords and hashtags in captions rather than comments to help posts appear in Search, while Adam Mosseri recommended adding context about the photo or video and using just a couple of hashtags rather than 20.12

How captions help people find content

Instagram for Creators advises placing relevant search keywords and hashtags in a post's caption rather than its comments so the post can be found in Search.1 Mosseri recommends adding context about a photo or video to its caption to help Instagram figure out what it is about.2 For account searches, Mosseri specifies that Instagram looks at the caption written when the post is first published.4

Caption filters and offensive-language warnings

Instagram's caption filters cover suggested posts, but not posts from accounts the viewer follows.5 Instagram's Help Center says the filters apply to captions and hashtags rather than comments, and do not affect suggested posts viewed on instagram.com.5 For a potentially offensive Feed caption, Meta's Newsroom describes a prompt telling the writer that the wording resembles captions reported for bullying, giving them an opportunity to reconsider their words.6
