InfantChart

"Free baby growth percentile calculators using WHO, CDC, Chinese, Down syndrome, and Olsen preterm standards. Track weight, length, height, and head circumference." That is how InfantChart introduces itself. To AI engines like ChatGPT and Perplexity it is partially visible, scoring 5.2 out of 10, readable in places and missing in others.

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

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). The site links to no social profiles, so there is nothing tying the brand to a wider presence.
