This SEO and GEO glossary brings together, in short definitions, the terms that come up all the time in organic search and artificial intelligence optimization projects. The idea is to serve as a quick reference for anyone who needs to understand what each acronym means without relying on jargon. The entries are organized by topic, from the most basic to the most specific.
Organic search terms
SEO
SEO (Search Engine Optimization) is the set of techniques that improves a website's presence in Google's organic search, without paying per click. It involves content, technical structure and authority.
SERP
SERP (Search Engine Results Page) is the results page the search engine displays after a query. Today it mixes links, ads, maps, featured snippets and AI blocks.
CTR
CTR (Click Through Rate) is the ratio between how many times a result was shown and how many times it was clicked. It is used to assess how appealing a title and description are.
E-E-A-T
E-E-A-T stands for experience, expertise, authoritativeness and trust. These are the quality signals Google describes in its documentation and that help distinguish trustworthy content, according to Google Search Central.
AI optimization terms
GEO
GEO (Generative Engine Optimization) is optimization so that content is used and cited by generative AI engines such as ChatGPT, Gemini and Perplexity.
AEO
AEO (Answer Engine Optimization) is optimization so that a passage becomes the direct answer displayed by search engines and voice assistants.
AI Overviews
AI Overviews is the AI-generated summary that Google displays at the top of some results, above the traditional links.
LLM and RAG
LLM (Large Language Model) is the language model that generates text, like the ones running behind AI chats. RAG (Retrieval Augmented Generation) is the technique in which the model retrieves external information before answering, which makes citable sources more relevant.
Technical and local terms
Structured data
Structured data is markup, usually based on the schema.org vocabulary, that describes content so search engines and AI tools understand what each part of the page is.
GBP
GBP (Google Business Profile) is the free profile that displays a business on Google Search and Maps. The consistency of this data is handled in the Google Business Profile service.
Featured snippet
A featured snippet is the highlighted answer block Google displays above the traditional links, extracted from a page. It usually contains a definition, a list or a table and is one of the most competitive formats in search.
Speakable
Speakable is the markup that indicates which passages of a page are suitable for being read aloud by assistants. It is used in content designed for voice search, helping the system choose what to read.
SGE and AI Overviews
SGE (Search Generative Experience) was the name Google used for the search experience with AI-generated answers, now better known as AI Overviews. Both terms describe the move to bring AI answers into search.
