AEO vs SEO vs GEO: What Is Actually Different and What to Fix First

AEO vs SEO is mostly a false choice. SEO (search engine optimization) earns your page a ranking and a click in Google's results. AEO (answer engine optimization) earns it a quote inside the answer itself: a featured snippet, Google's AI Overviews, ChatGPT or Perplexity. GEO, generative engine optimization, is the slice of AEO aimed at AI chatbots. And no, this AEO has nothing to do with the customs Authorised Economic Operator certificate. Here is where the three actually split.

AEO vs SEO vs GEO at a glance

The verdict: do SEO first, add AEO on top, and treat GEO as the chatbot part of AEO, not a separate project. Google says there are no additional requirements to appear in AI Overviews or AI Mode, but a page must be indexed and eligible to show with a snippet. AEO then adds four real differences, covered below, and a different way of keeping score.

What SEO, AEO and GEO each optimise for

SEO: ranked, then clicked

SEO gets a page crawled, indexed and ranked for the searches your buyers type, then earns the click with a title worth choosing. Success is positions, clicks and leads. The basics have not moved: one topic per page, sensible internal links, a fast phone experience and links from sites that vouch for you. If you build on Webflow, our Webflow SEO guide covers the platform settings.

AEO: being the answer

Featured snippets, voice assistants, AI Overviews and chat tools all lift a short passage from a page and present it as the answer. You are no longer competing for a position. You are competing to be the passage.

So AEO in SEO terms is a layer, not a replacement. Keep every ranking signal, then shape pages so a clean answer can be lifted: questions as headings, a direct answer under each, tables and lists that make sense on their own.

GEO: being cited by generative engines

The term comes from a November 2023 research paper titled "GEO: Generative Engine Optimization", which reported that its methods raised visibility in generative engine responses by up to 40% in its tests. In articles about AI search, "geo seo" usually means getting cited or recommended by ChatGPT, Perplexity, Gemini and Google's AI Mode.

In practice GEO and AEO overlap almost completely. The extra is that each AI tool runs its own crawler and search step, so there are more doors to keep open.

Where they overlap, and what is genuinely different

Most of the work is shared. Google's AI features guidance says SEO best practices remain relevant, that there is no special schema.org markup to add, and that you need no new machine-readable or AI text files to appear. If your SEO is sound, most of your AEO is done. Four things are different.

Being quoted vs being clicked

SEO earns a visit. AEO often earns a mention with no visit, because the reader gets the answer and moves on. Google says clicks from results pages with AI Overviews are higher quality.

So write the quotable part to sell even when nobody clicks: your name inside the definition, a number only you publish, a decision rule a reader can act on.

Crawl access for AI bots

SEO needs Googlebot and Bingbot. AEO needs more. OpenAI documents OAI-SearchBot, which decides whether a site can appear in ChatGPT search answers, separately from GPTBot, which collects training data. Each setting is independent, so you can allow search and refuse training. Perplexity recommends allowing PerplexityBot if you want to appear in its results.

Google-Extended controls Gemini training and grounding, and Google says it does not affect Google Search. Check your CDN too: OpenAI says the host must allow its published search bot IP addresses. Our explainer on how ChatGPT search works walks through the search step itself.

Entity clarity

Rankings are won page by page. Answers are about entities: who you are, what you do, where and for whom. An AI tool that cannot tell whether your brand is a studio, a supplement or a city will not recommend it.

Use one name, description and location everywhere, with Organization schema, a plain About page and matching profiles. For a new brand with no history, this is most of the battle; our guide to SEO for startups covers that zero-to-first-rankings stage.

Measurement

SEO has Search Console's rank, impression and click data. AEO is messier. Google folds AI Overviews and AI Mode traffic into the Web totals of the Performance report. On our own site, Search Console showed that 19% of Google web impressions in the 28 days to 17 October 2026 came from Google's AI features, and those impressions roughly doubled week on week at the end of that window.

ChatGPT and Perplexity have no console. Watch referrals from chatgpt.com and perplexity.ai in analytics, and once a month ask both tools the five questions buyers ask before hiring you. Log who gets cited. That log is your AEO rank tracker.

What to fix first

In this order, because each step is wasted if the one before it fails:

1. Make the page findable. Indexed, in the sitemap, not blocked by robots.txt, a CDN rule or a login.
2. Open the doors for AI search bots. Allow OAI-SearchBot and PerplexityBot. Decide separately, and on purpose, about training bots like GPTBot and Google-Extended.
3. Put the answer first. Under every question heading, answer in the first one or two sentences, then explain.
4. Make your entity unambiguous. One name, one description, Organization schema, a plain About page, matching profiles.
5. Add structure that lifts cleanly. Comparison tables, numbered steps, and FAQs whose markup matches the visible text.
6. Get mentioned on the pages AI tools read. Category lists, directories and review sites, because a chatbot answering "best X in Bangalore" often reads those, not only your own site.
7. Start keeping score. Search Console, AI referrals and the monthly prompt check.

To see where one page stands on the first five, run it through the free AEO readiness checker. It checks whether GPTBot, OAI-SearchBot, ClaudeBot, PerplexityBot and Google-Extended are allowed, plus structure and citable content. It cannot predict citations, and says so. If you would rather hand the whole list over, here is what AEO services should include.

So, AEO vs SEO: keep doing SEO, because Google's AI answers are built on it, then add the four differences on top. GEO is the same work, pointed at the crawlers ChatGPT and Perplexity run for themselves.

Frequently asked questions

What is GEO?

GEO stands for generative engine optimization: shaping your pages so AI tools that write answers, such as ChatGPT, Perplexity, Gemini and Google's AI Mode, cite or recommend you. The term comes from a 2023 research paper. In practice it overlaps almost entirely with AEO and rests on normal SEO, plus letting AI search crawlers such as OAI-SearchBot and PerplexityBot reach your site.

What is AEO in SEO?

AEO, answer engine optimization, is the part of SEO focused on being the answer rather than a link: featured snippets, voice results, AI Overviews and chatbot answers. It uses the same foundations as SEO, meaning crawlable, indexed pages with clear structure, then adds direct answers under question headings, clean tables and lists, a clear brand entity and access for AI crawlers.

Will AEO replace SEO?

No. Google says the best practices for SEO remain relevant for its AI features and that there are no additional requirements to appear in AI Overviews or AI Mode. A page must be indexed and eligible for a snippet first. AEO changes how you write and how you measure, since a quote may not bring a click, but it sits on top of SEO.

Is GEO SEO the same as local SEO?

Not usually. In articles about AI search, "geo seo" means generative engine optimization, getting cited by AI tools. Local SEO is ranking in a city or region through your Google Business Profile, local pages and reviews. The two meet, though. ChatGPT uses approximate location for local questions, so a consistent name, address and description helps both.
