Numdic home page

"Look up any integer on NumDic, the number dictionary: prime factorization, divisors, number-theory properties, and how the number is written in Roman, Greek, Arabic, Chinese, Hebrew and." That is how Numdic home page introduces itself. To AI engines like ChatGPT and Perplexity, though, it is barely visible: it scores 4.8 out of 10.

On the page it is passable on some structured data, a partly stated business identity and partial sitemap and link coverage. What holds it back is a heading structure that lays out what it offers, the technical files AI engines look for, such as llms.txt or an open robots.txt 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.
