Author Authority
The weight given to content because of who wrote it. Advice attributed to a named person with a real background is treated very differently from advice signed by a company or by nobody.

Microdata
An older way of marking up facts, written as attributes on the HTML itself rather than in a separate block. Still understood, but JSON-LD is now the safer choice.
robots.txt
A plain text file at the root of a site listing which bots may read what. It is a request rather than a lock — well-behaved crawlers obey it, and all the major AI crawlers do.
Hallucination
When an AI states something false with complete confidence — an invented price, a policy you never had, a product you do not sell. The usual cause is that the correct fact was not available anywhere it could read.
AI Overviews
The written summary Google now places above its search results, assembled from several pages and citing a few of them. Appearing inside one can bring visitors; being left out of one can quietly cost you the clicks you used to get.
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.
Prompt
The instruction or question you give an AI. The wording matters more than people expect: the same request phrased two ways can produce noticeably different answers.
