TL;DR

• SEO optimizes for rank position in a traditional search results list; success is measured by ranking and clicks.
• AEO optimizes for being chosen as one single, direct answer, a featured snippet, a voice assistant response, or a "People Also Ask" box.
• GEO optimizes for being cited as one of several sources synthesized into a generative AI answer, like a ChatGPT or Perplexity response.
• AEO predates GEO by years: it grew out of featured snippets and voice search, long before generative AI search existed.
• Featured snippet visibility on Google dropped by a shocking 83% in August last year, as the AI overview took the throne.
• SEO, AEO, and GEO overlap and reinforce each other - none of the three replaces the others.

What Is Search Engine Optimization (SEO)?

Search Engine Optimization (SEO) is the practice of improving a page's position in a traditional search results list, with the goal of earning a click on the website. SEO targets one output: a ranked list of links on a results page like Google or Bing.

The fundamentals of SEO are backlinks, technical site health, keyword targeting, and content relevance. Success in SEO is measured by ranking position and organic click-through rate, and, most importantly, whether a page ranks on page one or not.

What Is Answer Engine Optimization (AEO)?

Answer Engine Optimization (AEO) is the practice of structuring content to be selected as a single direct answer, rather than one option among ten suggested links. AEO targets placements like featured snippets, voice assistant responses, and "People Also Ask" boxes.

AEO predates GEO by a couple of years. This discipline grew out of optimizing for Google's featured snippets, introduced in 2014, and for voice assistants like Google Assistant and Amazon Alexa, which read out a single answer instead of displaying a list of suggested solutions. Success in AEO is binary: a page either becomes the featured answer or it doesn't, with no partial credit.

What Is Generative Engine Optimization (GEO)?

Generative Engine Optimization (GEO) is the practice of structuring content so that a generative AI system can retrieve, cite, and synthesize it into a longer, multi-source answer. GEO targets LLMs like ChatGPT, Perplexity, and Google AI Overviews.

Success in GEO is measured by inclusion and citation frequency inside a generated answer, often alongside several competing sources. A page can be one of three sources cited, all five, or none, and that mix can shift from answer to answer.

How Are SEO, AEO, and GEO Different?

SEO, AEO, and GEO are all optimized for three different outputs: SEO produces a ranked list of websites, AEO produces a single extracted answer, and GEO produces a synthesized answer assembled from multiple sources. That difference in output is what makes them three disciplines rather than one.

The shift between them is already visible in the real-life data. Featured snippet visibility on Google fell by about 83% since January to August 2025 as AI Overviews displaced them, according to Superprompt. The format AEO was built around is shrinking in real time, while GEO surfaces like AI Overviews, ChatGPT, and Perplexity are absorbing the queries that used to land in a snippet box. Let alone mention the downgrading role of SEO, which is also visible in the increase of zero click searches.

How Do They Work Together?

SEO, AEO, and GEO share the same foundation: clear writing, accurate sourcing, strong technical health, and well-structured pages. A page with weak fundamentals tends to underperform across all three, since rank position, answer selection, and AI citation all reward the same underlying signals of quality and trust.

Where they diverge is in the execution details. SEO leans on backlinks and keyword targeting. AEO leans on concise, extractable answer formats. GEO leans on chunk-level clarity, named sources, and consistent entity signals. Some marketers use the term "Search Everywhere Optimization" as an umbrella for treating all three as one coordinated strategy rather than three separate jobs, although they all require separate strategies.

How to Optimize for SEO vs. GEO vs. AEO

The practical playbook differs across all three categories, even though the underlying content strategies overlap:

Optimizing for SEO means investing in backlinks, technical site health, internal linking, and content that matches search intent for a target keyword.

Optimizing for AEO means writing short, self-contained answers, often 40 to 60 words, that directly address a single question, and using FAQ or Q&A structured data so that search engines can easily extract the answer.

Optimizing for GEO means leading each section with a direct answer, supporting claims with named sources and statistics, breaking content into chunks that make sense on their own, and keeping author and brand identity consistent across the site through structured data.
