ndbbio

"NDB Bio is the leading histopathology laboratory in providing comprehensive histology services to biomedical researchers performing research using human & animal tissue." That is how ndbbio of Baltimore, MD introduces itself. To AI engines like ChatGPT and Perplexity it is partially visible, scoring 5.3 out of 10, readable in places and missing in others.

On the page itself the strengths are clear: structured data describing the business, a clearly stated business identity and crawler access and the files AI engines look for. It is passable on partial sitemap and link coverage. What holds it back is a heading structure that lays out what it offers and credibility markers like credentials or reviews.

Away from its own site, 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. Those are earned elsewhere on the web, not fixed on the site itself.
