The short answer
SEO is the work of ranking a page in the normal list of search results. GEO, short for generative engine optimization, is the work of getting your business named or quoted inside an AI generated answer. They overlap, but they are not the same goal.
Google now shows an AI Overview on roughly a third of searches, and tools like ChatGPT and Perplexity answer millions of questions a day without showing a list at all. If your content is not shaped to be quoted, you can rank well and still be invisible in the answer people actually read.
- SEO ranks a page
- GEO earns a mention in the answer
- You need both in 2026
