"serso.com Personal domain of Sergio de Sousa · since 1994 This is a personal domain." That is how serso.com introduces itself. To AI engines like ChatGPT and Perplexity it is close to invisible, scoring 1.3 out of 10.

The page falls short on credibility markers like credentials or reviews, the technical files AI engines look for, such as llms.txt or an open robots.txt, structured data describing the business, a heading structure that lays out what it offers, a clearly stated business identity and sitemaps and entity links AI can follow.

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.

There is not much on the page to read either, about 82 words. The site links to no social profiles, so there is nothing tying the brand to a wider presence.
