Trainline: Search, Compare & Buy Cheap Train TicketsCloseBasketCloseLoading...Menu IconLoading...ChevronRightMultiPassengersPlusCheckExternalLinkTick IconPin IconGroup IconHelp Icon is a London business whose own site puts it this way: "Trainline is the world's leading independent rail and coach travel platform selling rail and coach tickets to millions of travellers worldwide, enabling them to seamlessly search, book and." To AI engines like ChatGPT and Perplexity, though, it is barely visible: it scores 4.5 out of 10.

On the page itself the strengths are clear: structured data describing the business, a clear heading structure, a clearly stated business identity, crawler access and the files AI engines look for and sitemaps and entity links AI can follow. What holds it back is credibility markers like credentials or reviews.

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. Those are earned elsewhere on the web, not fixed on the site itself.
