Merck.com

Merck.com is a business whose own site puts it this way: "We aspire to be the premier research-intensive biopharmaceutical company." 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: a clear heading structure, a clearly stated business identity, visible credibility markers and sitemaps and entity links AI can follow. It is passable on some structured data and basic crawler access.

Off the page there is only faint evidence that only a handful of sites link to it. Beyond that, the domain does not yet read as established, 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.

AI crawlers have visited 3 times in our tracking, including ClaudeBot (Anthropic) and Applebot (Siri). It does link out to several social profiles, which helps engines tie the brand together.
