SEO vs AEO vs GEO: How to Get Found in Google and AI Answers
The difference between SEO, AEO and GEO, and what a business site needs to be found in Google, AI Overviews, ChatGPT, Gemini and Perplexity.
By Muhammad Jamshed, CEO & Founder · Published · Last reviewed
Key takeaways
- SEO helps a page rank in search results.
- AEO helps a page supply the direct answer shown in AI Overviews, featured snippets and voice answers.
- GEO helps AI assistants such as ChatGPT, Gemini, Claude and Perplexity describe and recommend your business accurately.
- All three depend on the same base: crawlable pages, clear answers and consistent facts about your business.
What SEO, AEO and GEO mean
Search engine optimization (SEO) is the work of making a page eligible to rank in Google and Bing search results: crawlable HTML, relevant content, descriptive titles, internal links and a fast, usable page.
Answer engine optimization (AEO) focuses on the answer itself. A page that states a clear, sourced answer near the top is easier for Google AI Overviews, featured snippets and voice assistants to quote. Generative engine optimization (GEO) goes one step further: it makes your business easy for generative AI tools such as ChatGPT, Gemini, Claude, Perplexity, Microsoft Copilot and Google AI Mode to understand, trust and recommend when someone asks for a provider.
Compare the three
| Discipline | Where you appear | What it depends on |
|---|---|---|
| SEO | Organic results in Google and Bing | Crawlable pages, relevant content, internal links and page experience |
| AEO | AI Overviews, featured snippets and voice answers | A direct answer near the top of the page, with supporting detail below |
| GEO | ChatGPT, Gemini, Claude, Perplexity, Copilot and Google AI Mode | Consistent company facts, structured data, crawler access and mentions on other trusted sites |
How AI answer engines find your pages
Most AI search products do not invent an answer from memory alone. They retrieve current pages from a search index or their own crawler, then summarise what they found and link the sources. ChatGPT search uses OpenAI's OAI-SearchBot crawler, Microsoft Copilot draws on the Bing index, Perplexity uses PerplexityBot, and Google AI Overviews and AI Mode use the Google index.
Note: That means a page that is blocked in robots.txt, missing from the index, or only visible after JavaScript runs is much harder to cite. Google states that the foundational SEO practices also apply to its AI features and that no special AI markup is required. The practical work is to make the right pages crawlable, indexed and clear.
What to put on the page
- Answer the main question in the first two sentences, then add the detail
- Use headings that match how buyers ask the question
- Use a table when you compare options, prices or features
- State the facts an assistant needs: who you are, what you do, where you work, how pricing works and how to contact you
- Show a named author and a last-updated date on guides
- Keep visible FAQs short and specific, and mark them up only when they are on the page
Make your business facts consistent
AI assistants combine what your site says with what other sites say about you. If your company name, location, services or contact details differ between your website, LinkedIn, Google Business Profile and directories such as Clutch, the assistant has to guess. Use one company name, one description and the same contact details everywhere.
Tip: On your own site, Organization structured data with your logo, contact point, address and social profiles helps search engines connect those sources. An llms.txt file is an optional plain-text summary that some AI tools and agents read. It is not a Google ranking factor, but it is a cheap way to state your key facts in one place.
A technical checklist
- Allow Googlebot, Bingbot, OAI-SearchBot, PerplexityBot and ClaudeBot in robots.txt
- Serve the main content in the HTML, not only after JavaScript runs
- Submit your sitemap in Google Search Console and Bing Webmaster Tools
- Use IndexNow so Bing and other engines see new and updated pages quickly
- Give every page one canonical URL, a unique title and a unique description
- Keep pages fast and readable on mobile
How to measure progress
Use Google Search Console and Bing Webmaster Tools for impressions, clicks and indexing. In analytics, watch referral visits from chatgpt.com, perplexity.ai, gemini.google.com and copilot.microsoft.com. Once a month, ask the main AI assistants the questions your buyers ask and note whether your business is named and described correctly.
No agency can guarantee a ranking or an AI citation, because search and answer systems decide what to show. What you can control is whether your pages are eligible, accurate and easy to quote.
Questions buyers ask
These answers are a decision aid. They are not a ranking promise or a client result.
Is GEO replacing SEO?
No. GEO builds on SEO. AI assistants that search the web still rely on pages being crawled and indexed, so the SEO foundation comes first and GEO adds entity consistency and quotable answers on top.
Do I need special schema for Google AI Overviews?
No. Google says no special markup is needed for its AI features. Structured data still helps search engines understand your organization, services and FAQs, as long as it matches what is visible on the page.
Does llms.txt improve rankings?
Not in Google. It is an optional summary file that some AI tools and agents read. It is useful for stating your company facts and key pages, but it does not replace crawlable pages.
How long does it take to appear in AI answers?
It depends on how quickly your pages are crawled and indexed, how competitive the question is, and what other sites say about you. Measure monthly in Search Console, Bing Webmaster Tools and AI referral traffic rather than expecting a fixed date.
