Codebymath.com

Codebymath.com describes itself simply: "At Codebymath.com, you can learn how to code in the context of solving mathematical puzzles." To AI engines like ChatGPT and Perplexity, though, it is barely visible: it scores 4.6 out of 10.

The page falls short on a clearly stated business identity, the technical files AI engines look for, such as llms.txt or an open robots.txt, sitemaps and entity links AI can follow, structured data describing the business, a heading structure that lays out what it offers and credibility markers like credentials or reviews.

Away from its own site, 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. Those are earned elsewhere on the web, not fixed on the site itself.

AI crawlers have visited 2 times in our tracking, including ClaudeBot (Anthropic). There is not much on the page to read either, about 144 words. The site links to no social profiles, so there is nothing tying the brand to a wider presence.
