NOAA Tide Chart

NOAA Tide Chart is a business whose own site puts it this way: "Powered by the National Oceanic and Atmospheric Administration's (NOAA) APIs, our app delivers accurate and reliable tide data straight to your device." To AI engines like ChatGPT and Perplexity, though, it is barely visible: it scores 4.9 out of 10.

On the page itself the strengths are clear: a clear heading structure and sitemaps and entity links AI can follow. What holds it back is a clearly stated business identity, credibility markers like credentials or reviews, the technical files AI engines look for, such as llms.txt or an open robots.txt and structured data describing the business.

Off the page there is only faint evidence that only a handful of sites link to it and 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.
