Yixin Tian

Yixin Tian is a Toronto, ON business whose own site puts it this way: "Personal website and blog of Yixin Tian, machine learning engineer." 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: crawler access and the files AI engines look for and sitemaps and entity links AI can follow. It is passable on a workable page structure. What holds it back is structured data describing the business, a clearly stated business identity and credibility markers like credentials or reviews.

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.
