AEO vs SEO: What Actually Changes for a Small Business
A plain comparison of AEO and SEO for owners hearing new acronyms from agencies: what is different, what is the same work, and how to measure it.
AEO and SEO are not two separate programs. AEO (answer engine optimization) is the part of SEO that aims to be quoted inside an AI answer rather than clicked from a results list. The groundwork is identical, a few page-level habits are new, and the way you measure success is different. If an agency is pitching an "AEO package" on top of your retainer, this post helps you ask the right questions.
What is AEO, and how is GEO different?
AEO means making your pages the source an answer engine picks when someone asks a question: Google's AI Overviews and AI Mode, featured snippets, and assistants like ChatGPT, Gemini, Claude and Perplexity. GEO (generative engine optimization) is the same idea with a different name.
You will also hear LLMO (large language model optimization). Ahrefs' Ryan Law covered all three in his April 2025 piece GEO, LLMO, AEO: it's all just SEO and argued they are three names for one idea. Some consultants separate AEO (short answers, snippets, voice) from GEO (longer chat-style answers). The work on your site is the same, so treat the acronyms as labels, not line items.
The labels do point at a real shift. Part of your audience now asks a question and reads a generated paragraph instead of scanning ten links. If your business is named in that paragraph, you win the inquiry.
New to all of this? The plain-language version is what GEO is and why your business needs it.
What does SEO still do that AEO depends on?
Everything that gets a page found, indexed, loaded fast and trusted is still SEO, and AI answers are built on top of it. If a page cannot rank, it is unlikely to be cited.
Google's own documentation on AI features and your website (updated December 2025) says there are no additional requirements or special optimizations needed to appear in AI Overviews or AI Mode, that the usual SEO best practices still apply, and that a page can only be shown as a supporting link if it is indexed and eligible for a snippet in normal Search. Indexed and snippet-eligible is ordinary SEO.
ChatGPT works the same way. Ahrefs studied 1.4 million ChatGPT prompts in Why ChatGPT cites one page over another (April 2026) and found that 88% of the URLs ChatGPT ends up citing come straight from search. Their conclusion: to be cited, a page first has to be in the pool of search results the model pulls from, which means it needs to rank.
So the order has not changed. Crawlable site, clean indexing, fast pages, content that answers what people search for, and other sites that link to you. That is the floor. AEO is what you do standing on it.
What is actually different in AEO?
The real differences are how you shape an answer, how plainly you state facts, and how often other sites mention your brand. The goal moves from "get the click" to "be the source."
On the page:
- Question-shaped headings with a direct answer in the first one to three sentences, before the detail.
- Short FAQ blocks with self-contained answers that still make sense when lifted out of the page.
- Clear, specific facts: a price range, a timeframe, a yes or no. Vague copy gives an assistant nothing to quote.
- Titles that match the question. The Ahrefs study found cited pages had titles semantically closer to the prompt (and to the sub-queries the model fans out into) than non-cited pages.
- Structured data that matches the page. Google's May 2025 post on performing well in AI experiences on Search asks that everything in your markup also be visible on the page itself.
Off the page, brand mentions matter more. Law's piece notes that unlinked mentions barely move classic rankings, but that language models weigh them differently: being named is worth more to a model than to a search engine. Reviews, directories and local press that name your business help an assistant decide you are real, even without a link.
The last difference is the outcome. In SEO a good result is a click. In AEO it is often a citation inside an answer, with no visit at all. That changes what you measure.
How do AEO and SEO compare side by side?
| SEO | AEO | |
|---|---|---|
| Goal | Rank and get the click | Be the quoted source in the answer |
| Where you appear | Ten blue links, map pack, featured snippets | AI Overviews, AI Mode, ChatGPT, Gemini, Claude, Perplexity, voice |
| How you measure it | Clicks, impressions, position, leads from organic | AI referral sessions in GA4, brand mentions, citations, leads from those sessions |
| What you change on the page | Technical health, intent-matched content, internal links, backlinks | Question headings with direct answers, FAQ blocks, clear facts, matching structured data |
| Off the page | Links from relevant sites | Links plus unlinked brand mentions, reviews, directories |
| Timeframe | Months to build, compounds over years | Rides on the same timeline; citations follow rankings, mentions build slowly |
| Who does it | Your SEO and dev team | The same people |
Nothing in the right column needs a different skill set from the left. It needs the same people to add a few habits.
Should you hire an AEO agency or add it to your SEO work?
Add it to your SEO work. It is the same work, done by the same people, on the same pages. A separate "AEO package" priced on top of a retainer is usually a repackaging of things a competent SEO team should already do.
Law's conclusion was blunt: if you want more presence in AI output, hire an SEO. Google says no special optimization is needed. Ahrefs' citation data says ranking is the gate.
What to ask your current partner, or a new one:
- Which three pages would you restructure for direct answers, and what would the first paragraph say?
- Which customer questions do we not answer on one page each?
- Where should our business be mentioned that it is not today?
- How will you report AI referral traffic and brand mentions?
If the answers are specific, you do not need a second vendor. If you are choosing from scratch, our guide on how to choose an SEO agency has the full question list, and SEO retainer vs one-time audit explains why this work suits an ongoing engagement. At Premier Logic the developers and the SEO people are one team, so heading, FAQ and structured data changes come from one plan, not a hand-off between vendors.
How do you measure AEO results?
Measure three things: referral sessions from AI assistants in GA4, mentions of your brand on other sites, and citations of your pages in AI answers. Then tie those sessions to leads, as you would for organic.
In GA4, open Reports, Acquisition, Traffic acquisition, and look at Session source for chatgpt.com, perplexity.ai, gemini.google.com and claude.ai. The numbers will be small at first, so watch the quarterly trend and whether those sessions convert. Set up key events (form submissions, calls) first, or the number means nothing. Our post on how to measure SEO ROI covers tying sessions to revenue.
Google gives you impressions, not clicks. The Search Console Generative AI performance report shows how often your pages appeared in AI Overviews and AI Mode, but the clicks stay blended into the normal Web results of the Performance report. So impressions holding while clicks dip can mean an AI Overview is answering without the click. Our free reporting tool pulls Search Console and your chosen GA4 key events into one nightly report, which makes that pattern easy to spot.
For citations, once a month ask each assistant the five questions your customers ask most and note who gets named.
Quick answers
Is AEO replacing SEO?
No. AEO depends on SEO. Google says no additional requirements or special optimizations are needed to appear in AI Overviews or AI Mode, and Ahrefs' study of 1.4 million ChatGPT prompts found 88% of cited URLs came from search. A page that is not indexed, fast and ranking will rarely be cited. AEO adds answer-shaped content and brand mentions on top of that foundation.
What is the difference between AEO and GEO?
Mostly the name. AEO (answer engine optimization) and GEO (generative engine optimization) both describe making your pages the source an AI answer draws on. Some people use AEO for short direct answers and snippets and GEO for longer chat-style answers, but the changes you make to a website are the same for both. Ahrefs treats GEO, LLMO and AEO as three names for one idea.
Does AEO work for local businesses?
Yes. Local questions ("emergency plumber in Astoria," "best pediatric dentist near Park Slope") are exactly what people ask assistants. A complete Google Business Profile, a consistent name and address across directories, reviews that mention specific services, and a page per service with a direct answer at the top feed both local SEO and AI answers.
How much does AEO cost?
It should not cost extra. The work (question headings, direct answers, FAQ blocks, clean structured data, brand mentions) belongs inside normal SEO content and outreach. If an agency quotes a separate AEO fee on top of a retainer, ask which specific tasks it covers that the retainer does not. Usually the honest answer is none, so make sure your existing SEO scope includes those tasks.
Can I do AEO myself?
Partly. You can rewrite headings as questions, put the answer in the first paragraph, add a short FAQ to each service page, and make sure your business name and address match across directories. The harder parts are technical (indexing, speed, structured data) and off-site (earning mentions and links). Do the writing yourself if you have the time, and get help for the rest.
