How cancer vaccines work

How cancer vaccines work is a business whose own site puts it this way: "Immune cells called T cells and B cells look for specific antigens, usually small pieces of cells or viruses that the immune system recognizes as foreign." When AI engines look at it, they find little to work with. It scores 4.5 out of 10.

On the page it is passable on a workable page structure, basic crawler access and partial sitemap and link coverage. What holds it back is a clearly stated business identity, structured data describing the business and credibility markers like credentials or reviews.

Off the page, other sites link to it. Beyond that, 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.

AI crawlers have visited once in our tracking, including ClaudeBot (Anthropic). The business dates to 2006.
