TST Prep

TST Prep describes itself simply: "Prepare for your English proficiency test with TST Prep. Access expert resources, practice tests, and study guides for TOEFL® and DET." To AI engines like ChatGPT and Perplexity, though, it is barely visible: it scores 4.7 out of 10.

On the page itself the strengths are clear: structured data describing the business, a clear heading structure, a clearly stated business identity, visible credibility markers, crawler access and the files AI engines look for and sitemaps and entity links AI can follow.

Away from its own site, other sites link to it 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, there is no press coverage to draw on and nobody is discussing it where AI engines look. Those are earned elsewhere on the web, not fixed on the site itself.

AI crawlers have visited once in our tracking, including ClaudeBot (Anthropic). It does link out to several social profiles, which helps engines tie the brand together. The business dates to 2019.
