|---|---|
GEO targets AI answers | It helps your business get mentioned and described correctly in answers written by AI tools. |

Results vary by topic | The same study found that what works differs from one subject area to another. |
No special file required for Google | Google says you don't need special AI files or markup to appear in its AI features. |

What Is Generative Engine Optimization?
Generative engine optimization is the practice of making your business easy for AI tools to find, understand and recommend. "Generative engines" are tools like ChatGPT, Perplexity, Gemini and Google's AI Overviews that write an answer instead of only listing links. The goal of GEO is for your business to appear in those answers, described accurately, when someone asks a question you can answer.
Where the Term Comes From
The term was popularized by a 2023 research paper titled "GEO: Generative Engine Optimization", written by researchers from Princeton and other institutions and later presented at the KDD 2024 conference. The authors pointed out that businesses and content creators have little control over when and how their content appears in AI answers, and they studied what helps.
GEO, AEO and Other Names
You will also see AEO (answer engine optimization), LLM SEO and AI search optimization. These names overlap heavily. All of them describe getting your business into answers written by AI, and agencies often use them interchangeably.
Pro tip: don't get stuck on the label. When comparing agencies or tools, ask what they actually do and how they measure it.
How AI Answers Pick Their Sources
Many AI tools search the web before answering, then summarize what they find from sources they consider relevant and trustworthy. For a local business, those sources are usually your website, your Google Business Profile, review sites, directories and articles that mention you. Google's AI Overviews and AI Mode draw on Google's own search index.
What AI Tools Tend to Use
AI tools are more likely to use content that answers a specific question clearly, early and in plain language. Pages with a direct answer at the top of each section, an FAQ and reliable sources are easier to quote than vague marketing copy.
Why Consistency Matters
When your business name, address, services and description match across your website, listings and directories, AI has one clear story to repeat. When they conflict, AI may describe you incorrectly or leave you out. This is why brand positioning comes first in every GEO project we run.
AI recommends what it can describe with confidence.
GEO vs SEO: What Changes and What Stays
GEO and SEO share the same foundation: a site that is easy to find, crawl and understand. The difference is the goal. SEO aims for a high position in a list of search results. GEO aims for a mention and an accurate description inside a written AI answer, where often only a few businesses are named.
What Stays the Same
Good SEO still matters for GEO. Google says a page only needs to be indexed and eligible to show in search to appear as a link in its AI features, and it says there are no special requirements beyond that. Helpful content, a clear site structure and accurate business information support both.
What Changes
With GEO, the wider web matters more. Mentions on directories, review platforms and trusted articles help AI tools confirm who you are. Clear, quotable answers matter more too, because AI tools summarize rather than send every visitor to your page.
What the Research Says About GEO
The 2023 GEO paper tested content changes on a large set of questions and found that the right changes could raise a source's visibility in AI answers by up to 40% in its experiments. The researchers tested methods such as adding citations, quotations and statistics to content.
The same paper found that results varied by subject area, so no single method works everywhere. That is an important reminder for any business: GEO is a process of testing and measuring, not a one-time trick.
Pro tip: be cautious with anyone who guarantees a top spot in ChatGPT. AI answers change, and no one controls them.
How to Start With GEO
The best first step is to see how AI tools describe your business today. Ask ChatGPT, Perplexity and Google's AI Mode the questions your customers ask, note whether you are named and record which sources are cited. Save the date and screenshots so you can compare later.
Fix the Basics First
Make your business name, address, phone number, hours and services identical on your website, Google Business Profile, Apple Maps, Yelp and Bing. Remove outdated information such as old addresses or "coming soon" pages. These fixes are often the fastest way to change how AI describes you.
Create Content AI Can Quote
Write pages that answer real customer questions directly. Open each section with a short answer, use plain language, add an FAQ and cite reliable sources. Google also warns that mass-producing pages without adding value can break its spam policies, so quality matters more than volume.
Pro tip: write down the 10 questions customers ask you most and make sure your website answers each one clearly.
Comparing Ways to Do GEO
Option | Best For | Tradeoffs |
|---|---|---|
Do it yourself | Small businesses with time to learn and a simple online presence | Low cost, but easy to stop measuring consistently |
Your current SEO agency | Businesses whose agency already offers AI visibility with a clear method | Convenient, but AI work can become an afterthought |
A specialist GEO/AEO agency | Businesses that want focused AI visibility work and monthly reporting | Needs clear agreement on who updates the website and listings |
How to Measure GEO Results
Measure GEO by checking a fixed set of customer questions in several AI tools on a regular schedule. Record whether you are named, how you are described and which sources are cited. Because AI answers change from session to session, look at trends across several checks rather than one result.
Signals to Track
How many of your tracked questions mention your business
Whether AI describes your services and location correctly
Which sources AI cites when it mentions you
Visits from AI tools in your website analytics
Set Realistic Timelines
Fixing inaccurate information can change how AI describes you within weeks. Being recommended for competitive questions usually takes longer, often a few months, because it depends on listings, reviews and mentions building up over time.
