WellDuct

"Certified, professional air duct, dryer vent, chimney, and HVAC cleaning across New Jersey. NADCA-accredited. Transparent pricing." That is how WellDuct of Linden, NJ introduces itself. To AI engines like ChatGPT and Perplexity, though, it is barely visible: it scores 4.2 out of 10.

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

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.

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.
