BlockSign.online

BlockSign.online is a business whose own site puts it this way: "BlockSign legt op de Bitcoin-blockchain vast dat uw contract is getekend. Het document zelf blijft privé. De bevestiging dat er getekend is, staat voor altijd publiek." To AI engines like ChatGPT and Perplexity, though, it is barely visible: it scores 3.4 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 basic crawler access. What holds it back is a clearly stated business identity, structured data describing the business and credibility markers like credentials or reviews.

Off the page, almost no other sites link to it, 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.

The site links to no social profiles, so there is nothing tying the brand to a wider presence.
