In short
- GEO means being named or cited in AI-written answers. AEO means being the source of a direct answer. SEO means ranking. They overlap by roughly four-fifths.
- What is new underneath is small and real: entity clarity, answer-first writing, and schema that confirms both.
- If someone sells you GEO as a separate program from SEO, they are selling the same work twice.
- Do the shared foundation first, then the additions. Ignore anything with guaranteed or submission in it.
The acronym factory
In the late 1990s it was SEO. Then SEM, when ads arrived. Then SMO for social, ASO for app stores, and a brief and embarrassing period of growth hacking. Each arrived with a conference, a certification, and a line on a proposal. Some described real work. Most described work that already had a name.
The AI wave has been generous. Generative Engine Optimization, or GEO. Answer Engine Optimization, or AEO. AI Optimization, AIO. Large Language Model Optimization, LLMO. Conversational Search Optimization. AI Visibility. Several of these were coined within months of each other by agencies competing to own the term, and the definitions shift depending on who is invoicing.
None of this means the underlying change is fake. AI answers are real and they are taking a share of the searches that used to produce a click. What it means is that you should read the acronyms as marketing and read the work underneath as the thing you are actually buying. This guide translates.
When an industry invents four names for one thing in a year, the thing is real and the names are for sale.
The terms, in plain English
SEO: search engine optimization
Making pages that a search engine can find, understand and rank for the words people type. Twenty-five years old, well understood, and the base every other acronym stands on. The SEO basics guide covers it.
AEO: answer engine optimization
Being the source a machine uses when it answers a question directly rather than listing links. The term predates the chatbots; it started with featured snippets, the "people also ask" boxes, and voice assistants reading one result aloud. AEO is about the shape of the answer on the page: the question as a heading, a short direct answer beneath it, and markup that says this is a question and this is its answer.
GEO: generative engine optimization
Being named, cited or drawn from when a generative model writes a multi-paragraph answer, as Google's AI Overviews, ChatGPT, Perplexity and Copilot do. GEO adds the idea that the model is synthesizing several sources, so it cares whether you are a clear entity and whether other sources agree with you. The AI search guide is a GEO guide without the acronym.
AIO, LLMO and the rest
Synonyms for GEO with different agencies' fingerprints on them. Treat them as the same thing.
What is actually new underneath
Strip the labels off and compare the work. About four-fifths of it is SEO you should already be doing: crawlable pages, one page per service, titles that say what the page is, a complete Google Business Profile, reviews, internal links, speed. An answer engine cannot quote a page it never indexed, so nothing about AI makes that layer optional. If your site does not yet clear it, the SEO checklist comes before anything in this guide.
The remaining fifth is real and specific, and it comes in three parts.
Entity clarity. A generative engine builds a picture of your business from every source it can find and declines to name a business it cannot pin down. One name, one address, one phone, one category, one description, everywhere. This was always good local practice; it is now the price of admission.
Answer formatting. Pages that state the answer in the first passage, use the customer's question as a heading, and keep FAQ answers short enough to lift. Classic search tolerated pages that circled the subject. Answer engines do not.
Confirmation. Structured data that restates the visible facts in machine terms, and mentions on other sites that corroborate them. Engines cross-check before they name.
That is the whole of what is new. It fits on an index card, it is worth doing, and nobody needs a certification to do it.
SEO, AEO and GEO side by side
| SEO | AEO | GEO | |
|---|---|---|---|
| Goal | Rank on a results page | Be the single direct answer | Be named or cited in a written answer |
| Where it shows | Blue links, the Maps pack | Featured snippets, voice replies | AI Overviews, ChatGPT, Perplexity, Copilot |
| Unit of competition | A page against other pages | A passage against other passages | A business against other businesses |
| What the engine reads | Titles, content, links, speed, profile | Question headings, short answers, FAQ schema | All of that, plus every other site that mentions you |
| What you measure | Rankings, clicks, calls | Snippet ownership, voice mentions | Named or not, cited or not, branded search, calls |
| Share of the work that is shared | The base | Mostly SEO | Mostly SEO, plus most of AEO |
| Who should buy it separately | Everyone | Nobody | Nobody |
The last row is the point. The three are layers of one program, and [SEO and AI visibility](/services/seo-ai-visibility) is that one program.
The columns look different at the top and identical at the bottom. That is because they measure different outputs of the same input: a clear, specific, consistent, well-structured presence on the web. Improve the input and all three outputs move. Buy them as three programs and you pay three times for one afternoon of schema work.
What to actually do
- 1
Clear the SEO floor.
Crawlable, fast, one page per service, a complete Google profile, reviews coming in. The free audit tells you whether you are there.
- 2
Fix the entity.
Audit every listing for name, address, phone, category and description. Make them identical. Remove the old ones. This is a week of tedium and the highest-return step on the list.
- 3
Rewrite the first passage of each main page.
State what the service is, what it costs, how long it takes and where, in the opening hundred words. Then explain. The service page guide has the pattern.
- 4
Add question headings and a short FAQ.
Use the questions customers actually ask, in their words. Two to four sentences each. Mark them up with FAQ schema.
- 5
Add LocalBusiness and Service schema.
Matching the visible page exactly. If the page says one thing and the schema another, you have created the inconsistency you were trying to remove.
- 6
Earn a few mentions.
Suppliers, associations, local press, sponsorships. Independent confirmation is what a generative engine trusts most.
- 7
Test monthly.
A fixed list of customer questions, asked across the assistants, logged. The ChatGPT guide explains how to read the results.
What to ignore
A short list, because the ignorable things share a pattern: they promise control over something nobody outside the model companies controls.
Safe to ignore
- GEO submission and AI directory listing services. There is nothing to submit to. The money buys a spreadsheet.
- Guaranteed mentions or citations. Nobody can guarantee what a model writes. Anyone who says otherwise is guessing on your dime.
- A separate GEO retainer on top of an SEO retainer. It is one program. Ask for one price.
- Content written for the model instead of the customer. Keyword-dense, question-stuffed, faintly robotic pages. Models are trained on human preference and prefer what humans prefer.
- Proprietary AI visibility scores. Useful as a sales chart, not as a measurement. Your own monthly log of real questions is the measurement.
- Panic. AI answers are a share of searches, not all of them, and the businesses being named are the ones that did the boring work. Do the boring work.
If you would rather have it done, DataCram's SEO includes the answer-first and entity work as part of the ordinary program, and the AI visibility service adds the monthly testing across assistants. Either way you get one fixed quote, not three acronyms. The voice search guide covers the one corner of AEO with rules of its own: the answers that are read aloud.

Questions people ask
Straight answers
Generative Engine Optimization: the work of getting a business named, cited or drawn from when an AI system such as Google's AI Overviews, ChatGPT or Perplexity writes an answer. It is not a separate discipline from SEO. It is SEO plus entity clarity, answer-first page writing and structured data, measured by whether you are named rather than where you rank.
SEO aims to rank a page on a results page. AEO aims to be the source of a direct answer: a featured snippet, a voice reply, or the passage an AI quotes. The work overlaps heavily. AEO adds question-shaped headings, short direct answers and FAQ markup, which any competent SEO program should already include, so AEO is best understood as a checklist inside SEO rather than a second service.
Close enough to treat as one. AEO grew out of featured snippets and voice assistants and focuses on the shape of a single answer. GEO grew out of chatbots and AI Overviews and adds the idea that the engine is synthesizing several sources, so it weighs whether you are a clearly identified business that other sites confirm. The practical steps for both are nearly identical.
They need the work it describes, which is mostly ordinary SEO plus a consistent business record and pages that answer questions plainly. They do not need it as a separate program or a separate invoice. A small business that clears the SEO basics, cleans up its listings and rewrites its service pages to answer first has done GEO, whatever the proposal calls it.
If it is priced as an add-on to SEO, the honest add-on is modest: an entity cleanup across listings, schema, answer-first rewrites of the main pages, and a monthly testing routine. If it is priced as a standalone program comparable to SEO itself, you are paying twice for the shared four-fifths. We fold it into one fixed-price program with no long contract.
No. What a model names is decided by the model, from the public record of your business. What can be guaranteed is the state of that record: consistent listings, quotable pages, correct schema, growing reviews and mentions. Businesses with that record get named far more often than businesses without it. That is the work, and the outcome follows it.
