Enrich person has a model compare every account each platform’s search found with the person’s professional profile, and returns only the ones it’s confident are the person. On X, when the person’s profile links to an account, that account is looked up instead of a search (see Enrich person). Several accounts on one platform can match, for example a personal profile and the person’s own creator Page. A match is based on available public evidence and is not proof of account ownership. If a platform returns no accounts, the person may not be on it, their account may not say enough to connect it to them, or the lookup may have failed.

What the model compares

The model sees the person’s professional profile (name, headline, location, work history and education) and each account’s name, handle, bio, location, links and follower counts. It looks for overlap like the same employer, school, city or personal website, and for conflicts, like a bio that says “college student” for someone with a PhD. It doesn’t see profile photos. It never uses sensitive traits such as ethnicity, religion or health, even when a bio mentions them.

Videos

YouTube videos are matched the same way, and only matches are returned. A video matches when the person speaks in it, as a speaker, guest, interviewee or panelist, and its title, description or channel confirms it’s them with something from their profile, such as their employer, school or research topic. The channel can be anyone’s. A video where someone else talks about the person, their paper or their company doesn’t match, even when it names them; for a recorded paper talk, only the first-listed author counts as the likely presenter. The model reads the title, channel, the description snippet YouTube shows in search, and the view count and date. It doesn’t watch the video or read its transcript.

Accounts with nothing to compare

An account with no bio, links or location can only be compared by name. Instagram and TikTok search results have no bios, so each account’s full profile is read before ranking. If some can’t be read, those accounts are compared by name only. Those accounts usually aren’t confident enough to be returned. That doesn’t mean they aren’t the person; it means there’s nothing to confirm it. An empty, inactive account can still be theirs.

Ranking failures

Facebook requires a successful comparison and returns no matches if the model request fails. For the other account platforms, if the model request fails, every account found is returned, sorted by how closely the name matches, and none of them is enriched. The other platforms are unaffected.
