What’s the difference between SEO vs AEO vs GEO? The TL;DR is: SEO gets your page ranked in search engines like Google and Bing, AEO gets your content extracted as the answer within AI summaries and voice search, and GEO gets your brand cited inside AI-generated responses. These are three layers of one practice, not three separate practices. We’ll dive into the differences between SEO, AEO, and GEO in this article.

This article is for marketers, business owners, and anyone interested in understanding how to optimize for both traditional and AI-driven search. In many businesses, there’s someone saying “we need a GEO strategy,” and no one is certain on what it is or how to execute it. Understanding these differences is super important for building a comprehensive digital marketing strategy in the evolving search landscape.

Why Search Engines, AI Search, and Answer Engines Matter

There’s a shift toward AI driven search experiences, and organic visibility now spans both traditional search engines and AI engines. SEO professionals have more to account for when optimizing for search, and more challenges too – such as a decrease in clicks.

Google AI Overviews are now included in nearly half of all search results on Google, according to studies done by SimilarWeb and Semrush. This is unfortunately resulting in an increase in “zero click” searches. According to SparkToro, in the first four months of 2026, 68% of Google searches ended without a click.

And while there’s a decrease in organic clicks and an increase in AI generated summaries across platforms – AI features aren’t going away. Rather than showing up at the top in a list of links and earning a click to your website, the key to marketing your business is shifting toward being recommended, mentioned and cited by AI search engines in addition to (NOT instead of) traditional SEO.

Search Engine Optimization (SEO) Overview

Search engine optimizationis the practice of improving a website’s visibility and ranking in unpaid, organic search engine results. SEO targets traditional search engines like Google and Bing. SEO itself has evolved over the years, but includes a few key foundations that make up one unified strategy:

• On-page optimization focuses on keyword optimization within content marketing, meta descriptions, meta titles
• Technical SEO focuses on the backend infrastructure to help search engines understand a site’s web pages usually by improving the site structure, site speed, mobile responsiveness, internal linking, implementing schema markup, and more.
• Off-page SEO and authority building focuses on earning backlinks, brand mentions, and third party references.

Even though search engine results pages are changing from results like Google’s blue links to more synthesized answers and AI summaries, SEO remains more important than ever.

Search Engine Technical Checklist

A short checklist for covering technical SEO includes:

• ensure pages are crawlable and indexed
• verify semantic HTML and accessible headings
• optimize page speed and mobile responsiveness
• confirm structured data where appropriate

Answer Engine Optimization (AEO) For Direct Answers

Answer engine optimization involves optimizing your business’s content to show up within, you guessed it, answers. This includes creating content for things featured snippets and voice search, along with AI generated answers like Google AI Overviews and People Also Ask (or PAA for short).

AEO captures high-intent traffic looking for direct resolutions to queries. Before the larger AI models were introduced to the market, many SEO professionals had a head start on AEO for years by optimizing for featured snippets and voice search, which would provide direct answers to questions.

To optimize for citations in AI generated answers and format answers for voice assistants, we recommend providing clear, concise answer blocks near the top of the content, as high as possible above the fold. We recommend writing in natural language as you were talking to a friend next to you, along with including longtail keywords within content.

AEO Formatted Content Patterns

• create a one-sentence direct answer section
• use structured data, including clear, descriptive headings that match question intent
• include short, standalone definitions that can be easily extracted by AI crawlers

Generative Engine Optimization (GEO) Explained

GEO focuses on how AI systems interpret and synthesize content, and it involves optimizing your brand for being mentioned, cited and recommended within conversational AI platforms like ChatGPT, Perplexity, Gemini, Claude, and Google’s AI mode, and any other large language models.

To increase visibility in generative AI platforms, marketers and businesses need to prioritize clarity, structure, and credibility for AI systems. To do this, we recommend creating original, evidence-backed high quality content and structuring content with proper headings, ensuring your website’s entity signals are consistent sitewide, and ensuring your brand’s information is consistent across the web.

Since credibility is really important for GEO, building off-site authority such as optimizing your Google Business Profile and other online listings can help.

SEO vs GEO vs AEO: Head-to-Head Comparison

SEO, AEO, and GEO coexist as layers of one unified digital marketing strategy. Below are some of the differences with each.

GEO And AEO: How They Interact

AEO and GEO are very similar because it involves optimizing your business for AI systems and AI generated results. The only difference is what platform you’re optimizing for and what the search results look like.

The content must be clear and credible for GEO success. Since AI summaries prioritize short, concise answers, and GEO prioritized trustworthy, credible, deeper content, we recommend pairing concise answers with deeper supporting content.

Technology Differences: How Search Engines And Generative Engines Use Content

Search engines constantly crawl the web and maintain a giant index of pages, and then serve up results that match the user’s query and assumed intent most closely.

Answer engines and AI summaries within traditional results synthesize results and cite online content from their index to answer a search query that matches the user’s intent most closely, oftentimes providing citations for specific aspects of the summary.

Generative AI engines and large language model AI tools like ChatGPT, Perplexity and Claude use information from a large inventory of training data, and that training data is updated every so often to include new information. LLMs use Retrieval-Augmented Generation (RAG) to search the web and “ground” the query, essentially fact-checking themselves and pulling the most updated information for a topic. LLMS also use a query fan-out technique where they break a large question into a bunch of smaller questions in order to get a more complete picture before generating an answer.

AI Search Mechanics And Measurement

Both Bing and Google now offer a generative AI performance report.

• In Bing Webmaster Tools, this report is found in the left-hand navigation panel called “AI Performance” and it features two reports:
  • Ground queries, including the intent, topic, citations count and citation share percentage for each query in the report
  • Page URLs, including citations count for each URL in the report
• In Google Search Console, the report is featured in the left-hand navigation panel under “Performance” – but you need to click a drop-down arrow and select “Generative AI” to view the report. At this time of publishing this article, only impressions for each page URL is included in the Google report.

E-E-A-T And Trust Signals For AEO And GEO

E-E-A-T stands for Experience, Expertise, Authoritativeness, and Trustworthiness, and it’s a set of principles for evaluating quality and credibility in online content. The main goal for creating high quality content is making sure it’s for people-first.

Some ways you can demonstrate EEAT in your content include:

• showing clear authorship and the date of publishing
• including expert quotes and direct sources
• documenting any methodology for original data

Myth-busting Two Popular AI Search Optimization Theories

LLMS.txt Files
An LLMS.txt file is a proposed standard that uses markdown to provide a structured, concise outline of the website’s most important content for AI agents and large language models. Some marketing professionals will claim that in order to show in up AI results, you need to implement an LLMS.txt file on your website. However, there’s no evidence to suggest that any AI search platforms are using it, and no company has come out supporting the practice. Google has stated they ignore the file and don’t take it into account for AI generated answers, but that it won’t hurt if businesses decide to add it to their site.

Some SEOs suggest that just because Google doesn’t use it doesn’t mean other companies don’t, but there’s no research to suggest it improves AI search visibility yet.

Content “Chunking”
Google has confirmed there’s no need to “chunk” content or write content in a certain way in order to help AI systems understand it better. However, many SEOs have been able to demonstrate that structuring content and adding certain elements can help influence citation rate and mentions. Lumar’s Sharon McClintic also made a good case for understanding the concepts behind breaking content down for extractability.
