Johan de Jong

Johan de Jong describes itself simply: "Johan de Jong Home NL | ENG Johan de Jong is assistant professor in Continental Philosophy at Leiden University." When AI engines look at it, they find little to work with. It scores 3.6 out of 10.

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

Off the page, 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. None of that can be fixed on the page: it has to be earned.

AI crawlers have visited 2 times in our tracking, including ClaudeBot (Anthropic) and Applebot (Siri). There is not much on the page to read either, about 61 words. The site links to no social profiles, so there is nothing tying the brand to a wider presence.
