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.

Tool Use
An AI reaching outside itself to do something it cannot do alone: run a search, do arithmetic reliably, read a live page. Nearly every useful assistant depends on it.
Transformer
The model architecture behind almost every modern AI system, introduced in 2017. Its trick is paying attention to how every word in a passage relates to every other, which is what made fluent machine writing possible.
Well-Known URI
A standard location, always under /.well-known/, where machines look for information about a site — security contacts, API catalogues, agent details. Putting files there means they can be found without being linked.
AI Readiness
Whether a website can be reached, understood and quoted by AI assistants. It covers crawler access, structured data, clear headings, published contact details and speed — the unglamorous things that decide whether a model will name you.
Multimodal
An AI that handles more than one kind of input — text and images together, say, or audio and video. It is why you can now photograph a menu and ask an assistant what is in a dish.
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.
