OSOMac, Cesare Tagliaferri’s blog

OSOMac, Cesare Tagliaferri’s blog is a business whose own site puts it this way: "I created this site to talk about the applications I used to write. That part of my life is temporarily on pause, but the site lives mainly as my blog." To AI engines like ChatGPT and Perplexity, though, it is barely visible: it scores 4.7 out of 10.

On the page it is passable on a workable page structure, a partly stated business identity and basic crawler access. What holds it back is structured data describing the business, sitemaps and entity links AI can follow and credibility markers like credentials or reviews.

Away from its own site, other sites link to it. There is some, but not much, sign that the domain is only lightly established and there is little discussion of it. Beyond that, AI engines do not yet recognise it as a distinct business, there is no press coverage to draw on and it does not come up on Reddit. Those are earned elsewhere on the web, not fixed on the site itself.

AI crawlers have visited 2 times in our tracking, including ClaudeBot (Anthropic). The site links to no social profiles, so there is nothing tying the brand to a wider presence.
