Physics First

Physics First describes itself simply: "Video lectures I have created that go with my Physics First eTextbook. These are physics lectures." To AI engines like ChatGPT and Perplexity, though, it is barely visible: it scores 4.8 out of 10.

On the page itself the strengths are clear: a clear heading structure and a clearly stated business identity. It is passable on 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.

Away from its own site, other sites link to it. 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, nobody is discussing it where AI engines look 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 once in our tracking, including ClaudeBot (Anthropic). The site links to no social profiles, so there is nothing tying the brand to a wider presence.
