RDFa
Another attribute-based markup standard for embedding machine-readable facts in a page. Less common on business websites than JSON-LD, and largely equivalent in what it can express.

PerplexityBot
Perplexity’s crawler. Perplexity cites its sources prominently, so being readable by it is one of the more direct routes to a visible citation.
Generative AI
AI that produces something new — text, images, code, audio — rather than only classifying or predicting. The generative part is why it can write an answer about your business instead of just linking to it.
ClaudeBot
Anthropic’s crawler, which reads public pages for Claude. Like the others it identifies itself and follows robots.txt.
Speakable Schema
Markup identifying the parts of a page suitable to be read aloud by a voice assistant. Narrow in application, but it removes the guesswork about which sentence answers the question.
BreadcrumbList Schema
Markup describing where a page sits in the site’s hierarchy. It helps both search engines and assistants understand that a page is a service under a category, not a stray document.
Organization Schema
Structured data describing the business itself: name, logo, address, contact details, social profiles. The single most useful markup for being recognised, and the one most small sites are missing.
