That is how Jacques Xu · Newsletter introduces itself. As far as answer engines are concerned it may as well not exist yet: 1.3 out of 10.

The page falls short on a heading structure that lays out what it offers, structured data describing the business, a clearly stated business identity, credibility markers like credentials or reviews, the technical files AI engines look for, such as llms.txt or an open robots.txt 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. None of that can be fixed on the page: it has to be earned.

There is not much on the page to read either, about 11 words. The site links to no social profiles, so there is nothing tying the brand to a wider presence.
