Análisis de Aguas Residuales NOM

Análisis de Aguas Residuales NOM, based in San Andrés Cholula, PB, describes itself simply: "Laboratorio acreditado para análisis de aguas residuales bajo la NOM-001-SEMARNAT-2021, NOM-002-SEMARNAT-1996 y NOM-003-SEMARNAT-1997." To AI engines like ChatGPT and Perplexity, though, it is barely visible: it scores 4.0 out of 10.

On the page itself the strengths are clear: a clear heading structure, crawler access and the files AI engines look for and sitemaps and entity links AI can follow. It is passable on a partly stated business identity. What holds it back is structured data describing the business and credibility markers like credentials or reviews.

Away from its own site, other 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 once in our tracking, including ClaudeBot (Anthropic). It does link out to several social profiles, which helps engines tie the brand together.
