Semantic Search
Search that works on meaning rather than exact words, so a page can match a query it never literally contains. It is why writing naturally now beats repeating a keyword.

Structured Data Testing
Checking that your markup is valid and says what you meant. Worth doing after every template change, because broken structured data usually fails silently rather than visibly.
Content Signals
An extension to robots.txt that states not just who may crawl, but what they may do with what they find: appear in search, be quoted in answers, be used as training data. It lets you permit citation while refusing training.
JSON-LD
The format Google and the AI assistants prefer for structured data — a block of machine-readable facts tucked into the page. It states plainly what prose only implies: this is the business, this is the address, this is the price.
Product Schema
Markup for an item you sell: name, price, currency, availability, condition. Without it an assistant reading your shop has to guess the price from the page, and sometimes guesses wrong.
Computer Vision
AI that interprets images and video — reading a document, recognising a product, counting people. The part of AI that has been quietly working in industry for years.
HowTo Schema
Markup for step-by-step instructions, labelling each step in order. Useful for anything procedural, and easy for an assistant to reproduce accurately.
