SEO vs. GEO: What's Actually Different?
About 80% of what moves an AI engine to cite a brand by name is ordinary SEO: crawlable pages, clean structure, real third-party authority, and content that answers a question in its first sentence instead of working up to it. The other 20% is two specific things we would rather name precisely than dress up into a longer list. "SEO vs GEO" is the highest-demand question on this page, pulling roughly 1,900 Google searches a month as of this week.
The 80% that's just good SEO
If a page is blocked from AI crawlers by accident in robots.txt, has no clean heading structure, and buries its answer three paragraphs deep, no amount of GEO-specific tactics will fix it, because the engine cannot reliably retrieve or trust it in the first place. We published a longer version of this argument three weeks before this page existed: is AI search optimization just SEO. The short version holds up under a second look. Most of the category's advice, once you strip the new acronyms off it, is decade-old SEO discipline restated for a new consumer.
The 20% that genuinely is not SEO
Entity resolution is the first. A search engine ranks a page regardless of whether it is fully sure which company published it. An answer engine will not name a company it is not confident about, and an unsure engine does not throw a visible error. It skips the brand or describes a different one, and both failures look identical from the outside. We learned this against our own name: "managed agent" as a category term collides with hosted-runtime products from three larger companies, and no volume of content fixed that. Changing the frame did.
Measurement is the second. A search ranking is stable and ordinal from one check to the next. An AI answer is a distribution. Only about 30% of brands stay visible across back-to-back runs of an identical query, and citation share for the same brand, same question, same engine can swing 40 to 60% month over month with nothing else changed. A single check tells you almost nothing. This page exists partly to demonstrate the fix: a fixed question set, sampled repeatedly, reported per engine, against a control question that never gets shown.
Final thoughts
If someone sells you GEO as an entirely new discipline requiring an entirely new toolkit, ask them what fraction of their own recommendations are SEO fundamentals with a new label. Our honest answer is four-fifths. The remaining fifth is worth doing. It is not worth overselling.
