Chunking
Splitting a long page into smaller passages so an AI can retrieve just the relevant part. Pages with clear headings chunk cleanly; a single unbroken wall of text does not.

AI Citation
When an assistant names your website as the source of something it said, usually with a link. A citation is the AI-era equivalent of a first-page ranking — it is the thing worth competing for.
Google-Extended
The robots.txt setting that controls whether Google may use your content for Gemini and AI Overviews. It is separate from ordinary Google Search, so you can allow one and refuse the other.
Content Negotiation
When the same URL serves different formats depending on what the visitor asks for — HTML for a browser, Markdown for an assistant. It lets one address serve people and machines without either getting a compromise.
AI Search
Searching by asking a question in ordinary language and getting a written reply, rather than typing keywords and choosing from links. It changes what a website has to do: be readable and quotable by a machine, not just findable.
AI Share of Voice
How often your business is named when assistants are asked about your category, compared with competitors. There is no official figure, so it is measured by asking the same questions repeatedly and counting.
Reinforcement Learning
Training by trial, error and reward rather than by examples. It is how models are tuned to be helpful and to refuse things they should refuse.
