Block Websites on Chrome, Edge & Firefox — Free Parental Control Extension (2026)

Website-Blocker is a business whose own site puts it this way: "Free extension to block any website on Chrome, Edge & Firefox. Set schedules, block by category, and manage remotely. Trusted by 400+ families. Try free, no card needed." 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 and sitemaps and entity links AI can follow. It is passable on some structured data, a partly stated business identity and basic crawler access. What holds it back is credibility markers like credentials or reviews.

Off the page there is only faint evidence that only a handful of sites link to it and 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.
