The SEO & GEO Glossary by Nati Elimelech

Agentic SEO is adapting a site for AI agents that browse and act on it for users, not just crawlers reading it.

AI memory is what an assistant keeps about you from chats and files, and a main reason the same question gets different answers.

Crawl budget is the set of URLs Google can and wants to crawl on a site, set by crawl capacity and crawl demand.

Crawl capacity is Google's ceiling on the total time a server holds connections open for it.

Crawl demand is how much Google wants to crawl a site, separate from how much Google can crawl it.

An entity is a brand, person or concept search engines and AI models treat as one thing, with a name, attributes and links to other entities.

noindex is a rule in a meta tag or HTTP header that keeps a page out of the search index and out of results.

Platform properties are a Google Search Console property type that shows how social and video accounts perform in Google Search.

Query fan-out is the technique where an AI engine splits one question into several searches and builds one answer.

robots.txt is a text file that says which URLs crawlers may fetch. robots.txt controls crawling, not indexing.

Server-side rendering (SSR) is the approach where the server sends a page's HTML ready, instead of the browser building it in JavaScript.

A user-triggered fetcher is a bot that fetches a page because a user asked, not as part of proactive crawling.

web-bot-auth is an emerging protocol at the IETF: bots cryptographically sign requests, sites verify the sender.
