Stacker

Stacker describes itself simply: "Stacker syndicates brand editorial stories across vetted publishers, building the credibility brands need, and giving news outlets content at no cost." Measured against the twelve signals AI engines rely on, it scores 7.0 out of 10, a strong showing.

On its own pages the site does well on a clear heading structure, crawler access and the files AI engines look for and sitemaps and entity links AI can follow. It is passable on a partly stated business identity. What holds it back is structured data describing the business and credibility markers like credentials or reviews.

Off the page, other sites link to it, it turns up in press coverage, people discuss it in places AI engines read and it comes up on Reddit. 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.

AI crawlers have visited 2 times in our tracking, including GPTBot (ChatGPT). The business dates to 2017.
