Gmail

Gmail is a business whose own site puts it this way: "Gmail is email that’s intuitive, efficient, and useful. 15 GB of storage, less spam, and mobile access." To AI engines like ChatGPT and Perplexity it is one of the more visible businesses we measure, scoring 7.0 out of 10.

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

Away from its own site, other sites link to it, the domain reads as established, AI engines recognise it as a distinct business, it turns up in press coverage and people discuss it in places AI engines read. Beyond that, it does not come up on Reddit.

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