In GEO vs SEO, SEO is the work of ranking your pages in Google and Bing results, and GEO (generative engine optimization) is the work of getting your business named and your pages cited inside the answers that ChatGPT, Perplexity, Gemini, Claude, Google AI Overviews and AI Mode write.

That difference matters because more of your customers now ask those engines for recommendations. BrightLocal's 2026 Local Consumer Review Survey of 1,002 U.S. adults, published in February 2026, reported that use of ChatGPT and other generative AI tools for local recommendations rose from 6% in its previous survey to 45%. A good Google ranking doesn't put you in those answers automatically, and a rankings report won't tell you whether ChatGPT or Perplexity mentions you.

Look at the bottom row. GEO sits on top of SEO work, and what changes is the finish line and how you keep score.

Is GEO just SEO with a new name?

Partly. Google's guide to AI features and your website says, "The best practices for SEO remain relevant for AI features in Google Search (such as AI Overviews and AI Mode)." It also says a page must be indexed and eligible to be shown in Google Search with a snippet. A page Google can't index can't be used in its AI features.

The difference is what happens next. Google says AI Overviews and AI Mode may use a "query fan-out" technique, issuing multiple related searches across subtopics and data sources. Your page then competes to supply a fact or your name inside one written answer, not a spot in a list.

The term GEO comes from a research paper first posted in November 2023 and accepted to KDD 2024. Our plain guide to generative engine optimization covers what those researchers tested.

Does ranking well in Google get you cited by ChatGPT?

Not reliably, and it depends on the engine. In an Ahrefs study published in August 2025, the team searched 15,000 long-tail queries in Google and Bing, asked the same questions to AI tools, and checked where the cited pages ranked.

Ahrefs' explanation is that these tools tend to retrieve pages based on multiple variations of a question. Two limits apply: Ahrefs says results may have changed since it collected the data in early July 2025, and it measured which pages were cited, not which businesses were named or recommended.

For you, getting indexed is a requirement for Google's AI features, and Google rankings line up more closely with Perplexity's citations than with the others'. For ChatGPT, Gemini and Copilot, your rank is a weak guide to whether your pages get cited, so check those engines directly.

How do you measure GEO vs SEO?

For SEO, Search Console shows impressions, clicks and average position for your pages.

For Google's AI features, Google added Search Generative AI performance reports in Search Console, covering features such as AI Overviews and AI Mode, and says that as of August 31, 2026, they've rolled out to all websites worldwide. The launch post lists impressions, pages, countries, devices and dates. So you can see which of your pages appeared and how often, but none of those metrics shows what the answer said about your business.

For ChatGPT, Perplexity, Gemini and Claude, you check by asking. The end result is one simple sheet that shows, question by question and engine by engine, where you're named, cited or missing.

  1. Write down your customers' questions. Use their words, such as "who's a good estate planning attorney near me," not keyword fragments.
  2. Ask each engine on the same day. Put every question into ChatGPT, Perplexity, Gemini and Claude, and search it in Google for AI Overviews and AI Mode.
  3. Record three things. Were you named, was your page cited, and were you recommended? Note who showed up instead.
  4. Ask more than once. Ahrefs notes that the exact same search query run through AI can lead to wholly different citations, so one run is a sample.
  5. Repeat on a schedule with the same list. Read the results as a direction over time, and treat small changes with caution.

Hypothetical example: a family law firm ranks third on Google for "divorce lawyer near me." The office manager asks that question in ChatGPT, Perplexity and Google AI Mode one afternoon. AI Mode cites the firm's practice page, ChatGPT names two other firms, and Perplexity cites a directory listing with the firm's old address. The SEO report says page one. The GEO sheet says one citation across three engines and a listing to correct.

Should a local business put money into GEO or SEO first?

Start with the groundwork both depend on. Google's list for its AI features includes making sure important content is available in textual form and checking that your Business Profile information is up to date. Our checklist for ranking in ChatGPT covers access for OpenAI's crawlers. Then run the question sheet above before you pay anyone for GEO, so you know what needs fixing.

Before you spend on either, settle these questions.

You don't have to pick a side in GEO vs SEO, but you should know where you stand in each before you buy anything. Vector Index's AEO vs SEO vs GEO breakdown shows where the three overlap and differ, how answer visibility is measured, and what to ask any provider about scope. Read it before your next proposal lands, so you can tell what you're being sold.
