Short answer
GEO (generative engine optimization) is the work of getting your business named, described correctly and cited when people ask AI apps such as ChatGPT, Gemini, Perplexity, Claude and Google AI Overviews for advice. SEO tries to rank a page in a list of links. GEO tries to get your name into the answer itself. That depends on your own pages and on the third-party pages the AI apps read, such as lists, reviews and directories. Because AI answers vary, GEO needs repeated measurement with confidence ranges.

Why GEO matters now
Many buyers now ask an AI app for options before they visit any website. They type a full question, such as "which accounting app is good for a small shop in Pune", and get back a short written answer that names a few businesses. If you are not in that answer, the buyer may never reach your site. Unlike a search results page, there is no page two to scroll to.
This changes what "being found" means. In classic search, you fought for a position on a list of ten links. In an AI answer, you fight to be one of a handful of names, described in a sentence or two, often with a link to the page the AI app used as its source.
How AI apps decide what to say
Most major AI apps can search the web before they answer. Google documents this for Gemini as "grounding with Google Search". OpenAI and Anthropic offer web search tools in their APIs. Perplexity is built around search. When search is on, the AI app roughly does this:
- Turns the question into one or more web searches.
- Reads a small set of the pages that come back.
- Writes an answer from what those pages say.
- Often lists or links the pages it used. These are its sources, or citations.
When search is off, the AI app answers from its training data. That data can be months or years old, and your recent changes will not show.
So the practical question for any business is simple: do the pages the AI app reads name you, and do they say the right things about you? Our guide on how AI apps choose sources goes deeper.
GEO vs SEO in one table
| SEO | GEO | |
|---|---|---|
| Goal | Rank a page in search results | Be named and cited inside an AI answer |
| What the user sees | A list of links | A written answer with a few names and sources |
| What decides it | Relevance, links, page quality | The pages the AI app retrieves, and how clearly they state checkable facts about you |
| Off-site work | Backlinks | Being named on the lists, reviews, directories and media the AI app cites |
| Measurement | Rank position, fairly stable | Share of answers that name you, which varies from run to run and needs ranges |
The two overlap a lot. Google says pages need no special markup or files to appear in AI Overviews, only to be indexed and eligible for a snippet. Good SEO is still the base layer for GEO.
What the research says
The term GEO comes from a paper by Pranjal Aggarwal and colleagues, presented at KDD 2024. The authors built a test set of queries and tried different ways of rewriting web pages. They report that the best methods could boost a page's visibility in generated answers by up to 40%, and that what works varies across topics.
Methods that helped in their tests included adding statistics, adding citations to sources, and adding quotations. Methods like stuffing in keywords did not help much.
The three levers you control
Almost all GEO work falls into three buckets:
| Lever | What it means | Typical work |
|---|---|---|
| Your own pages | Pages on your site that answer buyer questions clearly | Answer-first pages, comparisons, how-to guides, a clear About page, FAQs |
| Other people's pages | The lists, reviews, directories and articles AI apps already cite | Honest outreach to list writers, review requests to real customers, directory profiles |
| Technical access | Whether AI crawlers can fetch and read your pages | robots.txt rules, server-rendered HTML, sitemaps, structured data |
Most businesses start with their own pages because it is fastest. But for "best X in India" questions, AI apps often lean on third-party lists, so off-site work matters just as much.
What good GEO work looks like, step by step
- Write down the facts about your business in one place (a fact sheet), and confirm every number and claim.
- List the real questions buyers ask, without naming your brand in them.
- Check those questions on each AI app many times, with live search on.
- For each question where you are missing, find the cause: no page, a weak page, or missing from the pages AI apps cite.
- Publish pages that answer the question first and contain checkable facts, dates and sources.
- Get listed, honestly, on the third-party pages AI apps already cite. Ask real customers for reviews.
- Compare the questions you worked on with ones you did not, and only trust changes that beat the noise.
Common misconceptions
- "GEO is a trick." It is mostly the slow work of being clearly described on pages that AI apps trust.
- "One screenshot proves it." AI answers vary from run to run. One answer tells you very little.
- "I need a special AI file to appear." Google says no special files or markup are needed for its AI features. Files like llms.txt are optional extras.
- "Asking ChatGPT about my brand shows my visibility." If you name yourself in the question, the AI app will talk about you because you asked. Real buyers do not name you.

Frequently asked questions
Is GEO the same as SEO?
No, but they overlap. SEO aims to rank a page in a list of links. GEO aims to get your business named and cited inside an AI answer. Good SEO helps GEO, because AI apps that search the web often start from search results.
Which AI apps does GEO cover?
The main ones are ChatGPT, Google Gemini, Perplexity, Claude and Google AI Overviews. Each picks sources in its own way, so results differ by AI app.
Does adding statistics and quotes always help?
Not always. The KDD 2024 GEO paper found these helped in its tests, and that results varied by topic. Measure on your own site before and after a change.
How long does GEO take to work?
There is no fixed timeline. AI apps that search live can pick up a new page once it is crawled and indexed. Answers based on training data only change when models are updated. Measure over weeks, not days.
Can I measure GEO with one screenshot?
No. AI answers change from run to run. You need many checks over time, reported with a confidence range, before you can say a change is real.
