Mark Johnson

Mark Johnson is a business whose own site puts it this way: "Product person, fitness enthusiast, and voracious reader and writer, living in Seattle, WA." To AI engines like ChatGPT and Perplexity it is close to invisible, scoring 2.4 out of 10.

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

Off the page there is only faint evidence that the domain is only lightly established and there is little discussion of it. Beyond that, almost no other sites link to it, 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.

The site links to no social profiles, so there is nothing tying the brand to a wider presence.
