Linear Algebra Done Right

Linear Algebra Done Right describes itself simply: "Linear Algebra Done Right Sheldon Axler The fourth and most recent edition of Linear Algebra Done Right is an Open Access book available in English, Chinese, Greek, Farsi, and Portuguese." To AI engines like ChatGPT and Perplexity it is partially visible, scoring 6.8 out of 10, readable in places and missing in others.

On the page itself the strengths are clear: a clear heading structure. It is passable on partial sitemap and link coverage. What holds it back is 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 and a clearly stated business identity.

Away from its own site, other sites link to it, people discuss it in places AI engines read and it comes up on Reddit. There is some, but not much, sign that the domain is only lightly established. Beyond that, AI engines do not yet recognise it as a distinct business and there is no press coverage to draw on.
