TL;DR Summary
SEO, AEO, and GEO answer three different questions. SEO is about whether your page can be crawled, indexed, and ranked. AEO is about whether a specific passage can be lifted out and shown as the answer. GEO is about whether a model will name your business inside a generated response. They share a foundation but are verified with different tools.
!Key Takeaways
- SEO optimizes for retrieval and ranking; it is the prerequisite for the other two
- AEO optimizes a specific passage so it can be extracted and displayed as the answer
- GEO optimizes whether a model is willing to name your business in a generated answer
- All three depend on the same underlying facts being consistent and machine-readable
- Each is verified with a different tool: Search Console, the Rich Results Test, and prompt testing
- None of them is a replacement for the others, and the order you fund them in matters
Definition: Generative Engine Optimization (GEO)
The practice of making a business likely to be named and described accurately inside an answer generated by a large language model — in Google's AI Overviews, ChatGPT, or Perplexity — rather than merely ranked in a list of links.
SEO, AEO, and GEO are three different questions, not three names for the same job. Ranking a page, getting a sentence quoted back, and getting your company named inside a generated answer each depend on different work — and each is confirmed with a different tool.
This page is the definitions and the mechanics. If what you actually need is a spending order, we wrote that separately in which one an Austin business should fund first; this one explains what you would be buying.
What is the difference between SEO, AEO, and GEO?
SEO makes a page retrievable and rankable. AEO makes a specific passage extractable as a direct answer. GEO makes a business nameable inside a model-generated response.
Do they replace each other?
No. They stack. A page that cannot be crawled and indexed cannot be extracted from or cited, so SEO remains the foundation for both of the others.
How do I know which one is failing?
Check them separately. Search Console shows retrieval and ranking, the Rich Results Test shows whether your markup is valid and eligible, and asking the assistants directly shows whether they will name you.
| SEO | AEO | GEO | |
|---|---|---|---|
| Question it answers | Can this page be found and ranked? | Can this passage be shown as the answer? | Will a model name this business? |
| Mechanism | Crawling, indexing, ranking | Passage extraction and display | Retrieval plus generation |
| What you change | Crawlability, internal links, depth | Front-loaded answers, definitions, markup | Consistent facts, proof, earned mentions |
| Unit of success | A ranked URL | A quoted passage | A named brand |
| How to verify | Search Console | Rich Results Test | Prompt testing, recorded over time |
SEO: can the page be retrieved at all?

SEO is the unglamorous layer and it is still the one that decides whether anything else is possible. A page has to be reachable, indexable, internally linked, and substantial enough to be worth ranking. Ahrefs' study of organic search traffic found that 90.63% of pages get no organic traffic from Google at all — overwhelmingly a retrieval and relevance problem rather than a formatting one.
Practically, this is where you confirm the boring things: the page returns a 200, the canonical points where you intend, it appears in your sitemap, it is linked from somewhere a crawler will actually reach, and the content covers the topic in enough depth to be a credible result. Get this wrong and no amount of schema will save the page.
AEO: can a passage be lifted out cleanly?

AEO narrows the target from the page to a passage. The question is whether a specific block of text can be extracted and displayed as the answer without a human editor rewriting it first. That favours writing that puts the answer in the first sentence and then elaborates, rather than building up to a conclusion.
The structural half is markup. Google's structured data documentation sets out what makes a page eligible for rich results, and the FAQPage reference covers question-and-answer markup specifically. Two rules save trouble: eligibility is not a guarantee of display, and your markup must describe content that is genuinely visible on the page. Marking up text a visitor cannot see is a policy problem, not a shortcut.
Definition: featured snippet
A result in which Google displays an extracted passage from a page above or within the standard results, attributed to the source URL. It is the most common display target for answer engine optimization.
GEO: will a model name you?

GEO is the newest of the three and the least mechanical. The output is not a ranked link or a quoted box; it is a sentence in which an assistant says who to hire. Google's own guidance on AI features is explicit that the eligibility basis is ordinary Search — which is the single most useful fact in this whole discussion, because it means GEO is not a parallel channel you can buy your way into.
Semrush's AI Overviews study and Search Engine Land's treatment of generative engine optimization are both worth reading in full and in their current versions, because the surface is changing quickly enough that any specific share-of-citations figure ages badly.
What holds up is the underlying requirement: the model needs a consistent, checkable picture of your business before it will put your name in an answer. That means your details agree everywhere they appear, your services are defined in plain language, your claims are attributable, and you are mentioned somewhere other than your own website. That is the work on our Austin AEO & GEO agency page.
How to tell which layer is broken
Diagnose them in order, because a failure at one level masks everything above it.
- Retrieval. In Search Console, confirm the URL is indexed and earning impressions. No impressions means an SEO problem; stop here and fix it.
- Extraction. Run the page through the Rich Results Test. Invalid or missing markup, or an answer buried three paragraphs deep, is an AEO problem.
- Generation. Ask ChatGPT, Perplexity, and Google's AI Overviews the questions your buyers ask, in your city. Record what they say, including whether the details about you are correct. Absence or inaccuracy here is a GEO problem.
Doing this quarterly and writing down the answers is more useful than any benchmark, because it produces a record specific to your business and your market.
The Central Texas angle
Austin is a comparison-heavy market. Buyers here research in public, read reviews, and increasingly ask an assistant for a shortlist before they contact anyone — which puts all three layers in play for the same query. Central Austin (78701, 78704) is dense enough that review history often decides the local pack, while the Williamson County growth areas around 78664 and 78665 have more households with no incumbent vendor.
If you want the paid competition and volume figures for your own category, pull them from Google Keyword Planner against your own account rather than trusting a quoted average. The same goes for your visibility: your Search Console data describes your market, and a published benchmark does not.
Do this now
- Confirm indexing (~5 min). Check one important URL in Search Console. If it is not indexed, nothing else on this list matters yet.
- Validate your markup (~5 min). Run your homepage and one service page through the Rich Results Test.
- Front-load one answer (~10 min). Pick a page and move the actual answer into the first sentence under the heading.
- Add one real definition (~10 min). Write a plain, factual definition of your primary service and place it high on that service page.
- Run five prompt tests (~15 min). Ask each assistant who to hire for your service in your city. Screenshot the answers and date them.
- Check your facts agree (~15 min). Compare your name, address, and phone on your site, your Google Business Profile, and two directories, character for character.
Conclusion
Treat these as three layers of one problem. SEO decides whether you can be retrieved, AEO decides whether you can be quoted, and GEO decides whether you get named — and all three rest on the same foundation of accurate, consistent, machine-readable facts about your business. Diagnose them separately, in order, with the right tool for each.

Frequently Asked Questions
What is the difference between SEO and AEO?
SEO works at the level of the page and aims at being retrieved and ranked. AEO works at the level of a passage and aims at being extracted and displayed as the answer itself. The practical difference shows up in how you write: AEO rewards putting the answer in the first sentence and supporting it with valid structured data, where SEO rewards depth, crawlability, and internal linking across the whole page.
Is GEO a separate channel from search?
No, and this is the most common misunderstanding. Google's documentation on AI features states that eligibility for its generative experiences is based on ordinary Search eligibility, so a page that is not indexed and relevant is not a candidate. GEO is better understood as an additional set of requirements layered on top of search — consistent facts, attributable claims, and mentions beyond your own site — than as a channel you can buy into directly.
Is traditional SEO still worth doing in 2026?
Yes, and it is the prerequisite rather than the legacy option. Extraction and generation both draw on content that has already been crawled and indexed, so retrieval failures propagate upward into every newer surface. Ahrefs' organic search traffic study found that the overwhelming majority of pages get no organic traffic at all, which is a retrieval and relevance problem before it is anything else.
Which should my business work on first?
Almost always SEO, because it gates the other two, and then AEO before GEO. We covered the sequencing question in detail in a separate post on which one an Austin business should fund first, including how the answer changes by business stage. This post is the definitional companion to it.
How do I measure whether GEO is working?
By recording it yourself over time. There is no console for generated answers, so ask the assistants the questions your buyers ask, in your city, and keep dated screenshots of what comes back — whether you are named, who is named instead, and whether the facts stated about you are right. Run the same prompts each quarter so you have a trend rather than a snapshot.
