Skeptical Science

"Examines the science and arguments of global warming skepticism. Common objections like 'global warming is caused by the sun', 'temperature has changed naturally in the past' or 'other." That is how Skeptical Science introduces itself. To AI engines like ChatGPT and Perplexity it is one of the more visible businesses we measure, scoring 7.1 out of 10.

On the page itself the strengths are clear: a clear heading structure and sitemaps and entity links AI can follow. It is passable on a few credibility markers. What holds it back is a clearly stated business identity, structured data describing the business and the technical files AI engines look for, such as llms.txt or an open robots.txt.

Away from its own site, other sites link to it, the domain reads as established, AI engines recognise it as a distinct business, it turns up in press coverage, people discuss it in places AI engines read and it comes up on Reddit.

AI crawlers have visited once in our tracking, including GPTBot (ChatGPT). It does link out to several social profiles, which helps engines tie the brand together. The business dates to 2007.
