The relationship between AEO vs GEO vs SEO

Leave a comment

In the past, optimizing your website meant paying attention to Search Engine Optimization (SEO). Properly done SEO would then help you get a good ranking in the results of search engines. These days, with AI being omnipresent, things have become a bit more complicated. Now, you must also optimize your content for generative AI engines and browsers. That is where Answer Engine Optimization (AEO) and Generative Engine Optimization (GEO) come into play. (We briefly touched upon this in our article on content marketing). This article explores the relationship between AEO vs GEO vs SEO. We also add some best practices. Let’s start with SEO, as it is the oldest of the three.

SEO

As mentioned above, SEO stands for Search Engine Optimization. It means improving a website so search engines like Google and Bing can find, understand, and rank it well. The goal is simple: you want to increase visibility in organic, unpaid search results.

SEO covers several areas. One is content: is it relevant and high quality? Another is language: does it match the words people actually search for? SEO also looks at a site’s technical structure and speed, its internal and external links, and its overall authority and credibility.

At its core, SEO has two audiences. It makes a website easier for search engines to understand. It also makes that website more useful for the people searching. Google puts it simply: SEO helps search engines understand your content, and it helps users find your site. For a deeper look at how to do SEO properly, Moz’s Beginner’s Guide to SEO is a good starting point. (See sources below).

AEO

Answer Engine Optimization (AEO) is the practice of structuring and optimizing online content so that search engines and AI systems can easily understand and use it to answer users’ questions. Google had noticed that most of the search queries it received were questions that people were looking for an answer to. So, they modified their algorithm. AEO originated with features such as Google’s featured snippets (= special summary boxes), knowledge panels and voice assistants. These provide direct answers instead of simply listing search results.

AEO focuses on clear, concise and authoritative content. It uses well-structured headings and accessible information that machines can easily extract and interpret. Today, AEO also covers AI-powered search and conversational systems. These systems combine information from multiple sources to generate answers. While SEO aims to improve a website’s visibility in search results, AEO aims to make its content a source of direct answers.

GEO

Generative Engine Optimization (GEO) is the latest evolution in web site optimization. It is the practice of optimizing digital content so that AI-powered search engines and conversational tools – like ChatGPT, Gemini, Perplexity and Claude – can easily find, understand and reference it.

GEO emerged with the integration of generative AI into search and information retrieval. Unlike traditional SEO, which focuses on improving rankings in search results, GEO aims to influence how AI systems select and use information when generating answers. It emphasizes high-quality, factual content, clear language, authoritative sources and reliable citations. The goal is to establish a website or brand as a credible source that AI systems recognize and reference in their responses. As Semrush explains, GEO shifts the focus from attracting clicks through search rankings to gaining visibility within AI-generated answers.

How AEO and GEO relate to each other

When it comes to AEO and GEO, the terminology isn’t standardized. Many authors now use the two terms interchangeably. Still, the most useful distinction is one of scope and emphasis.

Answer Engine Optimization is the broader concept. It means optimizing content so an answer engine can extract it, understand it, and use it to answer a user’s question. The central question of AEO is simple: can my content be selected as the answer to this question? This favours content that is explicit, well structured, and easy to extract.

An AEO-oriented page would provide an answer to a question with a concise, authoritative definition right away, then follow with supporting detail. Salesforce describes AEO as optimizing content for direct answers, including featured snippets, voice results, and AI-powered search. Ahrefs frames it similarly: making content visible and useful to systems that provide direct answers, rather than simply ranked links.

Generative Engine Optimization is narrower. It focuses specifically on generative AI systems that synthesize information from multiple sources and construct their own response. Rather than being extracted whole, your content becomes one input among many that the AI draws on to write its answer.

The term has an academic origin. A 2024 Princeton-led research paper introduced Generative Engine Optimization as a framework for improving how visible a source is within the responses generative engines produce. The researchers measured whether specific optimization techniques increased a source’s visibility in generated answers.

So, where AEO is about being extractable, GEO is about being trusted and cited within an answer built from many sources. AEO grew up around direct-answer surfaces. GEO starts from a different question: when a model composes an answer from many sources, what makes it choose yours? One agency sums it up as follows: AEO wins the citation, GEO wins the sentence. AEO makes you the source an AI cites. GEO makes you the brand an AI recommends inside the answer it writes.

Some consider GEO a subset of AEO: AEO covers everything from featured snippets to voice to AI, while GEO narrows in on large-language-model generative engines specifically. In day-to-day practice, however, the two overlap so heavily that the separation rarely changes what you actually do. Even Wikipedia states that there’s no academic consensus distinguishing the two terms as of early 2026. The words are frequently used interchangeably.

Best Practices

Current best practices are about making a website useful, understandable, technically sound and trustworthy. The main principles are:

  • Create genuinely useful, original content that satisfies the user’s search intent rather than writing primarily for search engines.
  • Use relevant search terms naturally, particularly in page titles, headings, introductory text and descriptive URLs.
  • Demonstrate expertise and credibility, especially for subjects where accuracy matters. Author information, references and authoritative sources can help.
  • Make pages technically accessible to search engines, with good site architecture, crawlable links, appropriate metadata, XML sitemaps and structured data where relevant.
  • Optimise the user experience: pay attention to mobile usability, page speed and loading performance, etc.
  • Build meaningful internal links so that both users and search engines can discover related content.
  • Earn quality backlinks from relevant, reputable websites rather than attempting to acquire large numbers of artificial links.
  • Keep important content current: update your content it when facts, laws, regulations or circumstances change.
  • Optimise for AI-engines and context, and not merely for individual keywords. Search engines, answer engines and generative engines increasingly try to understand the subject matter and relationships between concepts.
  • Avoid manipulative practices, such as keyword stuffing, automatically generated low-value pages, hidden text, link schemes and duplicate content created solely to capture search traffic.

Google’s own current guidance puts particular emphasis on helpful, reliable, people-first content, while its Search Essentials cover the technical and spam-related requirements.

For law firms, it is important that web site optimization should not be separated from authority and reputation. A well-optimised page explaining a legal issue is useful. But a page written by an identifiable lawyer – supported by appropriate legal sources, clearly dated and maintained when the law changes – provides considerably stronger signals of reliability. That way, your content becomes relevant not only to traditional SEO but also to AEO and GEO.
