What is the difference between SEO and GEO?

AI SEO — also called AI search optimization or GEO — tries to get a fact or brand quoted inside an AI answer. Traditional SEO tries to rank a URL on a results page. You still need a crawlable page — an engine cannot quote what it cannot fetch — but the winning unit is the answer block, not the blog post. That single difference changes how you write, how long the page is, what you pay for, and how you measure success.

If you searched for "AI SEO vs traditional SEO" or "AI search optimization vs traditional SEO," the short version is this: traditional SEO competes for one of ten blue links. AI SEO competes for one of the two or three sources a model cites when it writes the answer. Fewer slots, different rules, and a page shape most small sites have never published.

Side by side

What still carries over

• — Crawlability. If a page is blocked, slow, or client-rendered with no server HTML, no engine can use it.
• — Clear titles and headings. Both systems read them.
• — Real expertise and a named author. Both systems reward it, for different reasons.
• — Internal links, which help both crawlers and retrieval systems understand what a site is about.

What changes

In SEO you often write around a keyword and let the answer emerge. In GEO you write the answer first and let everything else support it. In SEO a longer page can outrank a shorter one. In GEO a longer page frequently loses to a short one that states the fact plainly with a source next to it.

Measurement changes the most. Keyword rank tells you nothing about whether Perplexity named you. The practical replacement is a fixed prompt set: 20–30 questions, run in each engine, scored the same way every time.

How we score a snapshot

1. 0 — not mentioned, and no page from your site is cited.
2. 1 — your site is cited or paraphrased, but the business is not named as the recommendation.
3. 2 — the business is named in the answer body.

Twenty to thirty prompts across four engines gives sixty data points and a maximum score of 120. Most small sites start between 0 and 8. The number matters less than the direction it moves after the pages ship.

Who should do which

• — If organic traffic is your main channel and it still converts, keep doing SEO and add GEO pages on top.
• — If you sell a considered local service and customers now ask an assistant first, GEO is the cheaper lever.
• — If you have no indexed site at all, fix hosting and indexing before either.

Sources

Ranking behavior claims should come from Google Search Central. Answer-assembly behavior should come from OpenAI, xAI, and Perplexity documentation. We do not treat third-party ranking studies as evidence of how a model chooses citations.

Is traditional SEO dead?

No, and anyone selling you that line is selling fear. Google still sends the overwhelming majority of search traffic, and a page that cannot rank or be crawled cannot be quoted either. What has changed is the click. When an AI Overview answers the question directly, the searcher reads the answer and never visits any of the ten blue links — so a page can hold its position and quietly lose its traffic. The practical response is not to abandon SEO. It is to make sure that when the answer is generated, your facts are inside it, so the shrinking pool of clicks goes to the cited sources.

Can one page do both?

Yes, and for a small business it should. An answer-shaped page — question as the title, 80-word direct answer, sources, FAQ block — also happens to match how people now type into Google. We see the same pages show up in both places: cited by an engine for the exact question, and ranking in ordinary results for the long-tail version of it. The pages that do neither are the ones written around a keyword instead of a question.

Where to start if you have neither

1. List the 20–30 questions customers actually ask you, in their words.
2. Check which of them your site answers on a dedicated page — for most small sites the honest answer is two or three.
3. Run those questions through ChatGPT, Claude, Perplexity, and Google AI Overviews and note who gets named. That is your baseline.
4. Write one answer page per missing question, sources included, and rerun the same questions in thirty days.

Those first steps are exactly what the free AI Customer Discovery Audit does for you, scored and documented across 20–30 commercial-intent questions. Either way, the work starts from real customer questions, not a generic keyword list.

A worked example

Take a septic company asking about SEO. The SEO version writes "Septic Pumping Services in Ulster County," targets a head term, and fights three directories for position four. The GEO version writes "How much does emergency septic pumping cost on a weekend in Ulster County?", answers with a price band and a response window in the first eighty words, cites the county health department page for permit rules, and closes with four questions the office answers by phone every week. The first page competes for a slot. The second page is the easiest correct thing for an engine to quote. Running both is normal, and the GEO page frequently ends up ranking too, because it matches how people now type.
