AEO vs. SEO: how to show up wherever buyers search‍

They may start with Google, move to ChatGPT to compare options, check a review site, go back to search to validate a claim and then ask Gemini a more specific question before they buy. The path changes depending on what they're trying to learn.

‍

For marketers, that creates a wider visibility problem. Ranking well in search still matters. So does being one of the brands an AI-powered search and answer tool recognizes, retrieves, and includes when it builds an answer.

‍

AEO, or answer engine optimization, is a relatively new term for the work marketers are doing to improve a brand's visibility in AI-generated answers. It overlaps significantly with SEO, but the way AI systems discover and present information creates some new considerations.

‍

Brands need to understand where those strategies diverge, where they reinforce each other, and why neither should be treated as a replacement for the other.

‍

AEO is about being part of the answer

‍

Answer engine optimization focuses on whether a company or its information shows up when an AI platform responds to a question.

‍

Sometimes that happens because the model retrieves a page from the company’s website. Other times it comes through a review platform, Reddit thread, directory, publisher or another third-party source the company has no control over.

‍

A company can publish the best explanation of its product category on its own site, but an AI system may still lean on G2 to compare vendors or Reddit to understand what users say about them. The information that shapes an answer can come from all over the web.

‍

Semrush’s 2026 index found that ChatGPT pulls roughly 15 sources per response and Gemini about three. Those figures are snapshots of how the platforms behaved in Semrush's analysis, not fixed rules for how either system will always work. The final answer may name even fewer brands, so there is no equivalent of ranking eighth and still appearing on the first page. If the model recommends three companies and yours isn’t one of them, the buyer may never know you were an option.

‍

AEO work focuses on improving the likelihood that a brand is accurately understood and surfaced for relevant questions. It helps AI systems understand what a company does, find useful information about it and see enough supporting evidence elsewhere to include it with confidence.

‍

SEO is doing more than it used to

‍

Search optimization has already moved well beyond chasing a blue link. Google results can include local listings, product results, video, forums, featured snippets and AI-generated summaries before a user reaches a traditional organic result. A good SEO program has had to adapt to those changes for years.

‍

SEO still depends on making important pages accessible to search engines, answering the questions people are searching, building authority around relevant topics and making each page easy for a search engine to understand. 

‍

Google's own guidance for its AI search experiences reinforces this overlap: create unique, helpful content for people and continue following established SEO fundamentals.

‍

Rankings are still part of the job, they just aren’t the whole job.

‍

And search remains a major research channel. Roughly half of customers still turn to search engines when researching information, making purchase decisions or looking for recommendations, so pulling resources away from SEO entirely to chase AI visibility would solve one problem by creating another.

‍

Where AEO and SEO start to separate

‍

One of the clearest differences between SEO and AEO is how much choice the buyer gets after the platform has filtered the results. Traditional search still relies on an algorithm to decide which pages appear and in what order, but the user can scan those results and choose which source or brand to explore. With an AI-generated answer, much more of that selection happens before the response reaches the user. The system can determine which sources to retrieve, which information to use and which companies to mention before the response reaches the buyer.

‍

Your own website carries enormous weight in SEO because it is the property you can optimize most directly.

‍

AI visibility makes the broader web presence of your brand more important as well.

‍

A 5W audit found that Wikipedia and Reddit together accounted for more than a quarter of U.S. ChatGPT citations. Review platforms can play a large role too. If an AI platform is trying to answer “What are the best options for X?” it has good reason to look somewhere that compares companies rather than accepting each company’s description of itself.

‍

SEO teams have years of experience tracking rankings, organic traffic and conversions. AI answers vary from engine to engine and can change as the systems change what they retrieve.

‍

AI visibility also varies by platform and by topic. A Semrush study of 50,000 brands across more than 1,000 topic areas found that only 15.2% had a clear brand leader in ChatGPT.

‍

BrightEdge found 62% disagreement between ChatGPT and Google AI on which brands to recommend, so being visible in one answer engine does not tell you much about another.

‍

For most companies, the more useful question isn't whether they are broadly "visible in AI." It's whether they appear consistently for the questions their buyers are asking.

‍

There is still a lot of overlap

‍

Even though the delivered results are different, much of the work that supports strong SEO also improves a brand’s chances of appearing in AI answers.

‍

It starts with the basics. If search engines can’t crawl or understand a page, an AI-powered search system may also have a harder time finding and using it. The same is true of the content itself. Weak or vague information does not become more useful just because the interface changed.

‍

From there, the overlap becomes even clearer. 

‍

People rarely ask one question and stop. They may want to know what something costs, whether it holds up, where it’s available, what other customers think or which option makes the most sense for what they need. 

‍

Pages that answer those questions give brands more opportunities to appear in traditional search and provide AI systems with useful material to retrieve and cite.

‍

How those answers are written matters too. 

‍

If someone has to dig through six paragraphs to find the useful part, they may leave before they get there. AI systems can struggle with the same kind of page. Put the answer where people and the systems processing the page can find it, then give them the detail they need to understand it and trust it.

‍

Trust also gets built beyond a company’s own website. People read reviews, check other sources and compare what they find before they make a decision. Search engines have long used those outside references to help judge which sources deserve attention, and AI systems look at many of the same places. The source mix may change, but the principle does not: what others say about a brand can influence whether that brand gets surfaced.

‍

Why brands still need both SEO and AEO

‍

The reason to invest in both comes down to how people research. 

‍

Someone may use Google to find nearby options, ask ChatGPT to compare a few of them, read reviews and then return to search when they want to check a specific claim. Some people reverse that process and start with an AI query first before turning to search for deeper, more specific research. For others, the path changes depending on the question they are wanting to answer.

‍

There isn't one universal buyer journey anymore.

‍

That creates a visibility problem for brands. Strong organic rankings can put you in front of someone using search, but they do not guarantee that an AI assistant will mention you. The reverse is true too. Showing up in an AI answer doesn't replace the value of being discoverable when someone searches for your company, product, or category.

‍

That is why SEO and AEO work better as parts of the same visibility program. 

‍

They reach people in different places, but those places are often part of the same research process. 

‍

The practical goal is making it easy for buyers to find you, understand you, and keep you in consideration, whether they are searching for a link or asking for an answer.

‍

What to do now

‍

If buyers are moving between search engines and AI platforms, brands need to be prepared to show up in both.

‍

Start with the SEO foundation that is already supporting your visibility. Keep important pages indexed, maintain site structure and build useful content around the questions buyers ask rather than creating pages simply because a keyword has volume.

‍

From there, look at the places beyond your own site that can influence whether a brand appears in an AI answer.

‍

Claim and maintain the review profiles, local listings, marketplace pages, and other third-party profiles that matter in your category. Make sure your hours, locations, product details, pricing ranges and other basic information are current. 

‍

Look for inconsistencies. Conflicting or outdated information across Google Business Profile, Yelp, retailer pages, review sites, or other sources can make it harder for an AI system to determine which version is accurate.

‍

Look at the questions behind your biggest search terms. A broad query usually contains several smaller ones. Someone researching a product may want to know how much it costs, how it compares with another option, what reviews say or whether it fits a specific need. Each of those questions is another opportunity to create something useful enough to rank in search or be retrieved by an AI-powered system.

‍

The writing itself should make those answers easy to find. If a page is built around a specific question, answer it early. Then give the reader the evidence and detail needed to understand the answer and decide whether it is useful.

‍

Pay attention to outside mentions. Review sites, industry publications, partner pages and legitimate community discussions can all affect what an AI system finds when it looks for information about a company.

‍

Measurement needs to account for both environments. Keep tracking organic rankings, search traffic and conversions. But also build a list of the questions buyers are likely to ask AI platforms and run them through the engines that matter to your audience. Record which brands appear and which sources those platforms use.

‍

The differences can help show where your visibility strategy needs attention. If you rank well but rarely appear in AI answers, look at the sources those systems are using and whether your content addresses the questions being asked. 

‍

If AI systems mention you but traditional search visibility is weak, there may be an SEO problem worth addressing.

‍

Buyers are going to keep moving between search engines and AI platforms depending on what they are trying to learn. 

‍

That makes visibility less about winning one channel and more about making sure the brand can survive the handoff from one to the other. 

‍

A company may be discovered in search, validated in an AI answer, compared on a review site and revisited through search again before a decision is made. 

‍

SEO and AEO both matter because they support different parts of that journey. 

‍

The brands that show up consistently across those moments give buyers more chances to find them, understand them and keep them in consideration.
