SEO vs AEO vs GEO: What's the Difference and Which One Does Your Brand Need?
Your customers now find answers in three places: Google's regular results, Google's own AI answers at the top of the page, and chatbots like ChatGPT. Each needs a slightly different approach, which is where the three terms come from.
This matters because AI answers take clicks. In a Pew Research Center study of US Google users, people clicked a regular result in 8% of visits when an AI summary appeared, against 15% when it didn't. Here is SEO vs AEO vs GEO in plain words, with one Indian shopping example and a clear answer on what to do first.
What is the difference between SEO, AEO and GEO?
The difference is where your brand shows up. SEO puts your page in the list of results. AEO puts your answer at the top, before the list. GEO gets your brand named inside an AI chatbot's reply. All three start from the same place: a useful, trusted website.
| SEO | AEO | GEO | |
|---|---|---|---|
| Goal | Rank your page | Be the direct answer | Get mentioned or recommended by AI |
| Where you show up | Google and Bing results | Featured snippets, People Also Ask, AI Overviews, AI Mode, voice assistants | ChatGPT, Perplexity, Gemini, Copilot |
| What the user does | Clicks your link | Reads your answer, may not click | Reads the AI's reply, may click a cited link |
| What matters most | Useful content, links, site speed | Clear question-and-answer format, a page that already ranks | Brand mentions across the web, reviews, clear facts |
| How you measure it | Rankings, organic traffic | Snippet wins, AI Overview and AI Mode impressions | Brand mentions in AI replies, AI referral traffic |
How does this look in real life?
One shopper, one product, three different results. Say someone in Pune wants a mixer grinder for idli and dosa batter.
- SEO: They search "best mixer grinder under 5000". Your buying guide ranks at position 2, and they click it.
- AEO: They search "how many watts mixer grinder for idli batter". Google shows your paragraph as the answer at the top of the page.
- GEO: They ask ChatGPT "which mixer grinder should I buy for idli batter?" and it names your brand in its reply.
Notice that each step needs fewer clicks to get an answer. That's why ranking alone no longer covers the whole journey.
What is SEO?
SEO (Search Engine Optimization) is making your web pages rank higher in search results so more people click through to your website. It rests on three things: content that answers what people search, a site Google can read easily, and trust from other sites that link to you. For a deeper look at what this involves, see our SEO services.
What is AEO?
AEO (Answer Engine Optimization) is writing and structuring your content so search engines and voice assistants pick it up and show it as the direct answer, in places like featured snippets, People Also Ask and Google AI Overviews. It works best on pages that already rank. Our guide to answer engine optimization (AEO) shows how to do it step by step.
What is GEO?
GEO (Generative Engine Optimization) is making your brand the one that AI chatbots like ChatGPT, Perplexity and Gemini mention, cite or recommend when they write an answer. GEO depends heavily on what other sites say about you, not just your own pages. Read more in our guide to generative engine optimization (GEO)
Is AI SEO the same as AEO and GEO?
Mostly, yes. "AI SEO" is the umbrella term, and AEO, GEO, AIO and LLMO sit under it. Search Engine Land describes AI SEO the same way, with each label covering an overlapping slice of the work. Don't get stuck on the acronym. Ask where you want your brand to show up, and work back from there.
What does Google say about AEO and GEO?
For Google's own AI answers, Google says it is all SEO. Its May 2026 guide says AI Overviews and AI Mode come from its core ranking systems, so optimising for them is "and thus still SEO". It also says you can ignore llms.txt files, splitting content into tiny chunks, and special schema for Google Search.
As Search Engine Journal pointed out, this doesn't settle things for ChatGPT or Perplexity, which may weigh signals differently. Our view: for Google's AI answers, do excellent SEO with answer-first pages. For chatbots outside Google, your reputation across the web matters more. That's why GEO still earns its own name.
Do AEO and GEO replace SEO?
No. Google's AI answers draw from the same index and ranking systems as its regular results, and AI chatbots with web search lean on pages search engines already trust. Weak SEO means weak AEO and GEO.
Think of a building. SEO is the foundation. AEO and GEO are the upper floors. You can design beautiful upper floors, but they won't stand on a cracked base.
Where do SEO, AEO and GEO overlap?
All three reward helpful content, a trusted brand and a healthy website. AEO adds one thing of its own: answers written so they can be lifted straight onto the results page. GEO adds another: your reputation on sites you don't own, like reviews, lists, YouTube and Reddit.
Google AI Overviews and AI Mode sit inside Google Search and pull from pages Google already ranks, so we file them under AEO. ChatGPT, Perplexity and Gemini's chat app are where GEO does most of its work.
Which one should your brand focus on first?
It depends on where you are today. Most brands should start with SEO, then add AEO and GEO on top of it.
| Your situation | Start with | Why |
|---|---|---|
| New website, little traffic | SEO | Nothing else works until Google trusts and ranks your pages |
| Getting traffic, but your pages don't show in answer boxes | AEO | You already rank, so small formatting changes can win the top spot |
| Buyers compare brands before buying (electronics, skincare, fashion) | GEO + SEO | People now ask ChatGPT "which brand should I buy", so being named there matters |
| Local business (clinic, restaurant, showroom) | Local SEO + AEO | Google Maps and quick answers drive most visits |
How do you measure SEO, AEO and GEO?
Each one has its own numbers, and most of the tools are free. Track them side by side, because a drop in clicks can hide a rise in AI visibility.
| What to track | Where to track it | |
|---|---|---|
| SEO | Rankings, organic clicks | Google Search Console, Semrush or Ahrefs |
| AEO | Featured snippets and People Also Ask won | Semrush or Ahrefs, plus a weekly manual check |
| AEO | AI Overview and AI Mode impressions | Search Console's Generative AI performance report, live for all sites since August 31, 2026 |
| GEO | Brand mentions in AI replies | A monthly test of 20 buyer questions in ChatGPT, Perplexity and Gemini |
| GEO | Visits from AI chatbots | A custom channel group in GA4. |

Frequently asked questions
Is GEO the same as AEO?
No, though they overlap. AEO is about being the answer inside search engines, like Google's featured snippets and AI Overviews. GEO is about being mentioned by AI chatbots like ChatGPT and Perplexity. AEO depends mostly on your own pages. GEO also depends on what reviews, lists and forums say about your brand.
Is SEO dead because of ChatGPT?
No. Google says its AI features run on its core search systems, and chatbots with web search pull from pages search engines already trust. SEO is changing, because fewer people click when an AI answer appears. But a site that doesn't rank rarely gets cited by AI either.
Can a small brand show up in ChatGPT answers?
Yes, especially in a narrow category. AI tools favour brands that many independent sources describe clearly and consistently. A small brand with genuine reviews, a few honest "best of" list mentions and clear facts on its own site can appear alongside much bigger names.
How long does it take to see results from AEO and GEO?
AEO changes on pages that already rank can show within weeks, once Google re-reads the page. GEO is slower, often a few months, because it depends on mentions building up across the web. AI answers also change between runs, so judge GEO by the trend, not one result.
Does Google AI Overviews count as AEO or GEO?
We file it under AEO. AI Overviews and AI Mode sit inside Google Search and draw from pages Google already ranks, so the work looks like SEO plus answer-first writing. Google itself calls all of it SEO. GEO covers chatbots outside Google, like ChatGPT and Perplexity.
