AEO vs SEO vs GEO: What Is the Difference and Which One Do You Need?

Three Acronyms, Three Different Jobs

If you have spent any time researching how to get your business visible online in 2026, you have probably encountered three acronyms that sound like they mean the same thing but do not. SEO, AEO and GEO. Search Engine Optimisation, Answer Engine Optimisation and Generative Engine Optimisation. The marketing industry has done its usual trick of creating confusing terminology for things that should be straightforward, so let me cut through it.

These are three distinct disciplines that address three different problems. They overlap in places, they share some common foundations, and a good strategy includes elements of all three. But they are not interchangeable, and treating them as though they are is one of the most common mistakes we see businesses and agencies making right now.

The confusion matters because it costs businesses money. If your agency tells you they are doing AEO but they are actually just doing SEO with a new label, you are paying for something you are not getting. If you invest in GEO without understanding how it differs from AEO, you may be optimising for the wrong platforms. And if you ignore all three and hope your existing search strategy covers it, you are losing visibility to competitors who have figured out the difference.

SEO: The Foundation You Already Know

Search Engine Optimisation is the discipline most businesses are familiar with. It focuses on getting your web pages ranked in Google's organic search results. You research keywords, create content targeting those keywords, build backlinks to increase your site's authority, optimise technical elements like page speed and mobile responsiveness, and track your progress through rankings and organic traffic.

SEO has been the backbone of digital marketing for over two decades and it is not going anywhere. Google still processes billions of searches daily, and organic rankings still drive significant traffic for businesses across every sector. If anyone tells you SEO is dead, they are either trying to sell you something or they do not understand the data.

What has changed is that SEO alone is no longer sufficient for comprehensive search visibility. The search landscape has fragmented. Google's own results pages are increasingly dominated by AI Overviews, featured snippets and knowledge panels that answer queries without requiring a click. Meanwhile, a growing percentage of searches are happening outside Google entirely, on platforms like ChatGPT, Perplexity and Claude. SEO gets you ranked on Google. It does not get you cited by AI assistants. That is where AEO and GEO come in.

AEO: Getting Cited as the Answer

Answer Engine Optimisation is the practice of getting your business cited when people ask AI powered platforms for recommendations and answers. When someone asks ChatGPT "what is the best marketing agency in Devon" or asks Perplexity "how do I improve my website's conversion rate", AEO determines whether your business appears in the response.

The mechanics are fundamentally different from SEO. AI platforms do not rank pages in a list. They synthesise information from multiple sources and present a single conversational answer. Your business is either mentioned in that answer or it is not. There is no position two or page two. There is cited and not cited.

AEO focuses on building what the industry calls entity authority. That means creating a clear, consistent digital footprint that AI models can confidently identify and recommend. It involves structured data and schema markup on your website, consistent information across directories and social profiles, content structured for easy extraction, and monitoring your citation rates across multiple AI platforms using tools like RankZero.

The key distinction between AEO and SEO is what you are optimising for. SEO optimises for rankings on a search results page. AEO optimises for inclusion in an AI generated answer. The signals that matter overlap but are not identical. Content depth, entity consistency and structured data carry more weight in AEO than they do in traditional SEO. Backlink volume, which is a primary SEO signal, matters less for AI citation than the quality and consistency of your overall web presence.

GEO: Optimising for Generative Output

Generative Engine Optimisation is the newest of the three and the one that causes the most confusion because it sounds like it should be the same as AEO. It is not, though the overlap is significant.

GEO specifically targets the generative AI components of search engines. The primary example is Google AI Overviews, which are the AI generated summaries that appear at the top of Google's search results. GEO also covers similar features in Bing's Copilot integration and other search engines that layer generative AI on top of traditional results.

The distinction between AEO and GEO is subtle but important. AEO is broader. It covers getting cited across all AI platforms including standalone tools like ChatGPT, Claude and Perplexity. GEO is narrower. It specifically focuses on the generative AI features embedded within traditional search engines.

In practical terms, GEO sits closer to traditional SEO because Google AI Overviews draw primarily from content that already ranks well in Google's organic index. If your pages are not ranking, they are unlikely to appear in AI Overviews. This means traditional SEO is a prerequisite for GEO in a way that it is not necessarily a prerequisite for AEO. ChatGPT may cite your business based on entity signals and content quality even if your Google rankings are modest. Google AI Overviews are far more likely to draw from pages that already perform well in organic search.

The Practical Differences in Execution

Understanding the theory is one thing. What matters for your business is how these disciplines differ in what you actually do on a day to day basis.

Content Strategy

For SEO, you create content targeting specific keywords with the goal of ranking individual pages. The focus is on search volume, keyword difficulty and topical relevance. You are writing for Google's algorithm and for the human who will click through from the search results.

For AEO, you create content designed to be extractable by AI systems. That means leading with clear, direct answers to specific questions, structuring content with logical heading hierarchies, and building topical clusters that demonstrate comprehensive expertise on a subject. You are writing for AI models that need to confidently summarise and cite your content.

For GEO, you create content that is both rank worthy in Google's traditional index and structured for AI Overview extraction. This is the most demanding content requirement because it needs to satisfy both traditional SEO signals and the formatting preferences of Google's generative AI layer.

Technical Implementation

SEO technical work focuses on site speed, mobile responsiveness, crawlability, internal linking and canonical structures. These are well established disciplines with mature tooling and clear best practices.

AEO technical work adds structured data and schema markup as primary concerns. FAQPage, HowTo, Article, Organisation and Product schema become essential rather than optional. Entity building through consistent NAP (name, address, phone) data across the web matters significantly. Your Google Business Profile, directory listings and social profiles all contribute to the entity signals AI models use to determine whether to recommend you.

GEO technical work combines both of the above with specific attention to how Google's AI Overview system selects and formats cited content. Featured snippet optimisation, passage ranking awareness and content structure that aligns with how AI Overviews synthesise information are all part of the GEO technical toolkit.

Measurement

SEO success is measured through Google Search Console data, rankings tracking, organic traffic and conversion rates from organic search. The tools and methodologies are well established.

AEO success is measured through citation monitoring across AI platforms. Tools like RankZero track how frequently your business appears in AI generated responses across ChatGPT, Perplexity, Claude and Google AI Overviews. Citation rate, citation share versus competitors and platform distribution are the key metrics.

GEO success specifically focuses on AI Overview inclusion rates, the click through rate impact of AI Overviews on your organic listings, and whether your content is being cited as a source within Google's generative responses.

Which One Does Your Business Need?

The honest answer is all three, but the priority depends on where your business currently stands and where your customers are searching.

If you have no SEO foundation at all, start there. AEO and GEO build on the signals that good SEO establishes. A business with no web presence, no content and no authority will struggle to gain AI citations regardless of how well they implement AEO tactics. SEO creates the foundation that everything else builds on.

If you have solid SEO in place but are seeing click through rates decline despite stable rankings, GEO should be your immediate priority. You are already ranking. The problem is that AI Overviews are answering queries before users reach your site. GEO addresses that specific problem by ensuring your content is the source being cited in those AI Overview responses.

If you want to capture visibility on platforms outside Google, particularly ChatGPT and Perplexity, AEO is where you need to invest. These platforms are growing rapidly and they represent an entirely new channel for reaching potential customers. The competitive landscape on these platforms is still wide open because most businesses and agencies have not figured out how to optimise for them yet.

For most businesses serious about search visibility in 2026 and beyond, the right approach is an integrated strategy that covers all three disciplines. The good news is that much of the work overlaps. Quality content helps all three. Strong entity signals help all three. Good schema markup helps all three. The incremental effort to cover AEO and GEO on top of existing SEO work is significant but not as large as starting from scratch on each one individually.

Why Most Agencies Are Only Doing SEO and Calling It AEO

This is the uncomfortable truth that nobody in the industry wants to talk about. AEO and GEO have become marketing buzzwords, and a significant number of agencies have added them to their service pages without actually changing what they do. They are still running traditional SEO campaigns, tracking traditional metrics, and delivering traditional results. The AEO label is a rebrand, not a new capability.

You can spot this by asking three questions. First, what tools do they use to measure AI visibility? If the answer is Google Search Console and a rank tracker, they are doing SEO. AEO requires citation monitoring across multiple AI platforms. Second, can they show you their own AI visibility data? At SuperHub, we track our own citation rates weekly and we share the data openly. We rank number one in Google AI Mode for motorsport sponsorship agency queries and we have the screenshots to prove it. An agency that cannot demonstrate their own AI visibility probably cannot deliver it for you either. Third, do they differentiate between platforms? If they talk about AI search as a single channel without distinguishing between ChatGPT, Perplexity, Claude and Google AI Overviews, they have not gone deep enough to understand the nuances that make AEO strategies effective.

This is not about criticising the industry. SEO is still valuable and most businesses need it. But if you are paying for AEO, you should be getting AEO. The distinction between the disciplines exists for a reason, and understanding it protects you from paying for relabelled services that do not address the actual opportunity.

Where to Start

If you want to understand where your business currently stands across SEO, AEO and GEO, the starting point is an audit that covers all three. Check your Google rankings and click through rates. Search for your core services on ChatGPT, Perplexity and Google with AI Overviews enabled. Note where you appear and where you do not. That gap analysis tells you exactly where to focus your investment.

We offer a free AI visibility audit that covers this ground in about fifteen minutes. We will show you your rankings, your AI citation rates, which competitors are being cited instead of you, and what the priority actions are. Whether you work with us or handle it internally, having the data gives you a clear picture of what each discipline can deliver for your specific business.
