GEO vs SEO: what is the difference?

The short comparison

• Goal: SEO wants a high position in a list of links. GEO wants a mention or citation inside a written answer.
• Where it shows: SEO in Google and Bing results. GEO in ChatGPT, Gemini, Copilot, Perplexity and AI Overviews.
• What is measured: SEO tracks rankings, clicks and traffic. GEO tracks mentions and citations across a fixed set of prompts.
• What decides it: SEO depends on relevance, technical health and links. GEO depends on clear answers, consistent facts and presence on sources the engines cite.

What they share

Both need a site that can be crawled, content that answers real questions, and trust earned from other sites. A page that ranks well is more likely to be retrieved by an AI engine, so strong SEO helps GEO directly.

Where GEO adds work

GEO pays more attention to how an answer is phrased, since engines quote short, direct statements. It also looks beyond your site, to the directories, review platforms and publications that engines draw on, and it needs its own measurement because there is no ranking report for AI answers.

Which should you start with?

If your site has technical problems or thin content, fix those first: that is SEO, and it lifts both. If you already rank and are missing from AI answers, GEO work is where the gap is. Most plans run them together.
