SEO wins your business a position in a list of links. AEO wins your business a mention inside an AI answer, with no list and no competing links on the page at all. The two are not separate budgets. Most of the foundation, crawlability, structured data, consistent listings, clearly stated facts, is shared between them.
A simple comparison
| SEO | AEO | |
|---|---|---|
| Goal | Rank a page in a list of search results | Be named or cited inside an AI generated answer |
| What success looks like | A high position, more clicks to the page | A mention or citation, whether or not anyone clicks through |
| Main signals | Crawlability, content depth, links, page experience, structured data matching the page | The same signals, plus entity consistency across the web and AI specific crawler access |
| How you measure it | Rankings and organic traffic in Search Console and analytics | Dated transcripts from repeated buyer prompts, since there is no AEO ranking report |
What Google itself says about the overlap
This is not just a framing choice. Google's own documentation for AI features in Search states that the best practices for SEO remain relevant for AI features in Search. The same page says there are no additional requirements or special optimizations necessary to appear in AI Overviews or AI Mode, and no special schema.org markup beyond what good SEO already uses.
Where AEO adds emphasis
AEO is a specialization within SEO, not a rival discipline, and what it adds is emphasis rather than a new toolset:
- Entity consistency. The same name, address, phone number and core facts about your business everywhere they appear, not just on your own site.
- Crawler access for AI bots. Confirming that crawlers like OAI-SearchBot and GPTBot, not just Googlebot, can reach your site.
- Answer first content. Stating the direct answer in the first sentence or two, so a model can lift it cleanly, rather than building up to the point over several paragraphs.
- Prompt testing. Actually asking ChatGPT, Perplexity, Gemini and Google AI Overviews the questions your buyers would ask, instead of only checking keyword rankings.
Where GEO fits
GEO, Generative Engine Optimization, describes the same work from a different angle. AEO focuses on being the source an engine cites. GEO focuses on how a model selects sources while it composes an answer. In practice the tactics overlap almost entirely, and most of what improves one improves the other.
What a small business should do first
Before spending on content or outreach, confirm the basics work. Check that AI crawlers can actually reach your site, since a blocked crawler makes everything downstream pointless. Then state your core facts plainly and consistently, on your site and anywhere else you are mentioned. Then test a handful of real buyer prompts across the engines your customers actually use, and treat that as your baseline rather than a guess.
Frequently asked questions
Is AEO a replacement for SEO?
No. AEO is a specialization within SEO, not a rival discipline. It runs on the same foundations: crawlability, structured data, consistent listings and clear content. Google itself says the best practices for SEO remain relevant for AI features in Search.
What is GEO, and is it different from AEO?
AEO and GEO describe the same work from two angles. Answer Engine Optimization focuses on being the source an engine cites. Generative Engine Optimization focuses on how a model selects sources while composing an answer. The tactics overlap almost entirely.
Do I need special tools or markup for AEO that SEO does not use?
No. Google states plainly that no new machine readable files, AI text files or special schema.org markup are needed to appear in AI features. AEO work uses the same structured data and technical SEO practices, applied with more attention to entity consistency and crawler access for AI specific bots.
What should a small business do first?
Confirm AI crawlers can reach the site, make sure business facts are stated plainly and consistently, and test a handful of real buyer prompts across ChatGPT, Perplexity, Gemini and Google AI Overviews before spending on anything else.
