The SEO & GEO Glossary by Nati Elimelech

Agentic optimization is adapting a website so AI agents can complete tasks on it for a user.

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.
