GEO vs SEO: what is GEO and how does it differ?
By Alona Marketing · Last updated:
Short answer
GEO, generative engine optimization, is the work of getting your business named and cited in answers from AI assistants such as ChatGPT, Perplexity and Gemini. SEO aims for a position in the search results. GEO builds on SEO: assistants find their sources through search, so without solid SEO foundations GEO does not work.
What exactly is GEO?
With GEO the goal is not a click on a blue link but a mention in the answer itself. An AI assistant composes an answer from pages it finds and cites those sources. GEO makes sure your pages, and the pages about you, are among them, and that they are accurate.
What is the difference between GEO and SEO?
- Goal: SEO wants a position in the search results, GEO wants a mention or citation in the answer.
- Unit: SEO thinks in keywords, GEO in full questions as a customer asks them.
- Sources: in SEO your own site counts most, in GEO listing and review sites weigh just as heavily.
- Format: GEO calls for a short, direct answer at the top of the page that an assistant can take over.
- Measuring: SEO measures positions and traffic, GEO measures whether you are named, in what position and with which source.
What do you still need from SEO?
Everything that makes a page found and read: a technically healthy site, fast pages, a sitemap, clear internal links, a logical URL structure and pages that rank. Assistants with web search use search results as their starting point. A page that is not indexed does not exist for them.
What did we see when we tested it?
Snapshot from 11 November 2026, tested with ChatGPT and Perplexity with web search on. AI answers differ per run and per user. This says nothing about fixed positions and is not a guarantee.
- Asked which agency helps with visibility in ChatGPT and Google, Perplexity named nine agencies, and each has its own dedicated GEO page. ChatGPT, for the same question, said it could not verify a specific agency and gave selection criteria instead.
- Both assistants cited sources by domain. The pages that were cited answered the exact question in plain text.
Where do you start with GEO?
Start by measuring: which questions do your customers ask and who is named today? Then work through the checklist, from crawl access to mentions on other sites.
Frequently asked questions
- Does GEO replace SEO?
- No. GEO builds on SEO. Without indexing, technical health and authority, AI assistants do not find your pages and cannot cite you.
- What does GEO stand for?
- GEO stands for generative engine optimization: optimising for generative search engines and AI assistants that write an answer themselves.
- Which AI assistants does GEO cover?
- Mainly the assistants that search the web and cite sources, such as ChatGPT with web search, Perplexity, Gemini and Google's AI answers.
- Does GEO need different copy?
- Often, yes. A page should answer the question directly and literally, with concrete facts such as location, languages and services. Generic marketing language is rarely cited.
