21 Lessons

21 Lessons is a business whose own site puts it this way: "Sharp thinking on software and business for customer success, sales engineers, and developers who need both worlds to make sense." Its AI visibility score is 5.6 out of 10: the engines can find it, but they do not have much to hold on to.

On the page it is passable on a workable page structure, a partly stated business identity, basic crawler access and partial sitemap and link coverage. What holds it back is structured data describing the business and credibility markers like credentials or reviews.

Off the page, other sites link to it and people discuss it in places AI engines read. There is some, but not much, sign that the domain is only lightly established. Beyond that, AI engines do not yet recognise it as a distinct business, there is no press coverage to draw on and it does not come up on Reddit. None of that can be fixed on the page: it has to be earned.

AI crawlers have visited once in our tracking, including ClaudeBot (Anthropic). The business dates to 2019.
