Nulli

Nulli, based in Merelbeke, Oost-Vlaanderen, describes itself simply: "Nulli is uw specialist in houtwormbestrijding, schimmelbestrijding en het plaatsen van vogelwering. 25 jaar ervaring en de nodige technische kennis!." 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, a clearly stated business identity, crawler access and the files AI engines look for and sitemaps and entity links AI can follow. It is passable on some structured data. What holds it back is credibility markers like credentials or reviews.

Off the page there is only faint evidence that the domain is only lightly established. Beyond that, almost no other sites link to it, 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.

It does link out to several social profiles, which helps engines tie the brand together.
