I guess the best term would probably be 'searchability' then. You want something where info comes up if you type it into Google/Bing/Kagi/your search engine of choice, and where there's enough of a community that other people will have experienced similar issues to you in the past. (for this reason, it's also probably better to choose projects with unique/well known names that don't conduct their support operations on Slack or Discord).
