"We rank on page one for this keyword. Why doesn't ChatGPT mention us?"

It's one of the most common questions we hear from teams who start tracking their AI visibility with AIclicks. It also explains the GEO vs SEO question better than any definition.

Search Engine Optimization (SEO) gets your pages ranked in search results. Generative Engine Optimization (GEO) gets your brand named and cited in the answers ChatGPT, Gemini, Perplexity, and Google's AI Overviews write. 

The two share a technical foundation. Google says its SEO best practices still apply to AI Overviews and AI Mode, and that no special optimization is required to appear in them. So ranking still matters, but it's only one input. AI assistants rewrite the question into their own searches, pull from Reddit threads, reviews, and YouTube videos, and name a handful of brands in a single answer.

So, the major differences sit in three places: which queries you compete on, which sources shape the answer, and how you measure the result.

I lead content at AIclicks, where we track how AI assistants answer questions about our own category every day. This post covers where GEO and SEO overlap, where they split, and what to change first, with examples from our own tracking data.

What is SEO?

SEO (Search Engine Optimization) is the work of getting your pages to rank in the organic results of search engines like Google and Bing. A search returns a ranked list of links, and SEO aims to put your page near the top of that list for the queries your buyers use.

It covers three areas:

• Technical SEO: making sure search engines can crawl, render, and index your pages.

• On-page SEO: matching each page to a query's intent with useful content, clear headings, and descriptive titles.

• Off-page SEO: earning links and mentions from other sites that signal your pages can be trusted.

SEO results are measured in rankings, impressions, clicks, and the organic traffic and conversions those clicks bring.

What is GEO?

GEO (Generative Engine Optimization) is the work of getting your brand mentioned, recommended, or cited in answers written by AI assistants: ChatGPT, Gemini, Perplexity, Claude, Copilot, and Google's AI Overviews and AI Mode.

These tools read sources and write a single answer. They name brands in the text, link to pages as citations, or both. GEO aims to make your brand one of the names in that answer and your pages among the sources behind it.

The term comes from a 2023 research paper by researchers from Princeton and several other institutions, later accepted at KDD 2024. They built a benchmark of queries across domains and found that specific content edits could raise a source's visibility in generative engine answers by up to 40%, with results varying by domain.

GEO work covers four areas:

• Content written so an AI can lift and quote individual passages.

• Presence on the sources AI cites, such as Reddit threads, review sites, YouTube videos, and third-party comparison articles.

• Technical access, so AI crawlers can reach and read your pages.

• Tracking how often AI assistants mention and cite you across a set of prompts.

What's the difference between GEO and SEO?

SEO competes for a position in a list of links. GEO competes for a place inside one written answer. The table sums up how that plays out, and the five points below it explain each difference.

What are the 5 key differences between GEO and SEO?

1. What you win: a ranked link vs. a mention in the answer

SEO wins you one of ten organic positions on a results page. Ranking fifth still earns some clicks.

GEO wins you a mention or citation inside a single AI answer, which usually names a handful of brands. If you're left out, you get no exposure for that question.

2. Who writes the search: the user vs. the AI

In SEO, you optimize for the query the user types. In GEO, the AI rewrites the user's prompt into several searches of its own and builds one answer from the results. Google calls this query fan-out and confirms AI Overviews and AI Mode may use it.

Our AIclicks tracking data shows how far those searches drift. Across 304 prompts and 1,499 ChatGPT searches between August 29 and September 28, 2026, ChatGPT used the user's exact wording 0.4% of the time, and 40% of its searches added brand names the user never typed.

To see what ChatGPT searches for and which brands it names for your own prompts, use a ChatGPT SEO tracker.

One example, with brand names replaced:

Prompt: best ai search monitoring tool

ChatGPT searched for:

• best AI search monitoring tools brand visibility AI overviews 2026

• AI search monitoring tools ChatGPT Perplexity brand visibility monitoring AI search mentions 2026

• AI search monitoring tools [Brand A] [Brand B] [Brand C] [Brand D] AI search visibility

ChatGPT chose the brands before reading any page. If the model doesn't associate your brand with the category, you miss that search, and keyword research won't show you the gap.

3. What shapes the result: your own pages vs. third-party sources

In SEO, your own page ranks, and other sites mainly contribute links.

In GEO, other sites become part of the answer: the Reddit thread ChatGPT cites, the YouTube review Gemini summarizes, the listicle that sets the shortlist. 

Ahrefs' study of 75,000 brands found branded web mentions correlated with AI Overview visibility at 0.664, against 0.218 for backlinks.

4. The role of rankings: the goal in SEO, one input in GEO

In SEO, a top ranking is the goal. In GEO, it's one input among several, and a weaker one than a year ago.

In a July 2025 study of 15,000 queries, Ahrefs found only 12% of URLs cited by ChatGPT, Gemini, Copilot, and Perplexity ranked in Google's top 10 for the original prompt. For AI Overviews, the share of citations from top-10 pages fell from 76% in July 2025 to 38% in March 2026.

Add a sample of fan-out queries to your rank tracker to see whether you rank for the searches the AI actually runs.

An Google AI Overview tracker shows which of your pages Google's AI Overviews cite for your keywords and which they skip, so you can compare that with your rankings.

5. How results behave: stable rankings vs. answers that change each run

Google rankings for a query stay fairly stable from day to day. Ask ChatGPT the same question twice and you can get different brands in a different order. 

That's why GEO is measured as how often you appear across repeated runs of a fixed prompt set.

What stays the same between GEO and SEO?

Well, obviously more than the "SEO is dead" crowd admits. 

Ahrefs' Q1 2026 AI search benchmark report found Google sends 190 times more traffic to websites than ChatGPT. Walking away from SEO to chase AI visibility would trade your largest channel for a smaller one.

The on-site work carries over almost entirely:

• Crawlability and indexing: AI search features retrieve from search indexes. A page that isn't indexed can't be retrieved.

• Clear, well-structured pages: Descriptive headings, a direct answer near the top of each section, and tables for comparisons help both Google snippets and AI extraction.

• Real expertise: Named authors, first-hand data, and sourced claims make a page worth citing for a search engine and a language model alike.

• Technical health: Speed, clean HTML, and working internal links matter to every crawler.

I part ways with the "GEO is just good SEO" club on one point. They're right about the on-site work but underrate the off-site work covered above, which most SEO programs reduce to link building.

"In SEO, you compete for a position on a page you can see and control. In AI answers, most of the pages that decide whether you're mentioned belong to someone else, so a big part of the work is getting onto those pages with something useful to say." - Matas Kibildis, Head of Growth at AIclicks

What should you do differently for GEO?

These five changes are where GEO work departs from a standard SEO program.

1. Build a prompt set next to your keyword list

Take your 20 to 30 most valuable keywords and rewrite each as three to five questions a buyer would ask an assistant. Add the constraints real buyers include: team size, budget, industry, the tool they're switching from. "GEO tool" becomes "best GEO tool for a 10-person agency."

Track that prompt set across the assistants your buyers use and read the actual answers, not only the scores. The answers show you which competitors get named, what the AI says about you, and which sources it leans on.

AIclicks speeds up the first part. Its setup wizard reads your website and services and suggests the prompts buyers in your category ask, grouped by topic. Prompt Discovery keeps adding new ones as you go, each with an estimated search volume.

2. Write for the fan-out queries

Export the fan-out queries for your prompt set and group them by theme. Each theme needs a page that answers it directly. In our ChatGPT data, 39% of searches added a year and 40% named specific products, so current-year roundups and comparison pages between named products are the first gaps to check.

Our free query fan-out analysis tool simulates the sub-queries an AI engine is likely to run for any seed query. Inside AIclicks, the Fanouts tab logs the real sub-queries behind every prompt you track. Writer 2.0 uses that fan-out data when it researches a new article, so the draft covers the searches AI already runs in your space.

On pages that already exist, update the facts, show a visible last-updated date, and add the specific details fan-out searches ask for. Our guide on how to optimize for AI Overviews covers the on-page side in more depth.

3. Get onto the pages AI already cites

For each prompt where a competitor is mentioned and you aren't, list the URLs the assistant cited. Those pages are your outreach list: listicles you can ask to be included in, Reddit threads you can answer with real experience, YouTube reviewers who cover your category.

Include video in that list. Ahrefs' Q1 2026 AI search benchmark found YouTube mentions were the strongest signal of AI visibility among the factors it measured.

The Sources tab in AIclicks does the listing step for you: filter to prompts where you're not mentioned and it shows the exact URLs cited instead, ranked by how often they appear. If Reddit dominates your category, our guide on using Reddit for AI citations and the free Reddit threads finder will get you started.

"I've seen brands hurt themselves by trying too hard: keyword stuffing, fake forum posts, or loading up schema without real content. Build real authority. Be transparent, provide actual expertise, and let others cite you naturally." - Rokas Stankevicius, Founder of AIclicks

4. Make each passage quotable on its own

AI assistants lift sections, not whole pages. Write every section so it answers its heading in the first sentence or two and still makes sense if it's the only part someone reads. Name the product or concept instead of saying "it". Put numbers next to their source.

The Princeton GEO study tested edits like adding statistics, quotations, and cited sources to existing content, and those were among the changes that lifted visibility. Since they're also good editorial practice, you give up nothing on the SEO side by making them.

5. Check that AI crawlers can reach your pages

Open your robots.txt and confirm you aren't blocking the crawlers that power AI search, such as OAI-SearchBot (ChatGPT search), PerplexityBot, and ClaudeBot. 

Check your CDN settings too: some CDNs offer a one-click "block AI bots" setting that can shut these crawlers out without anyone on the content team knowing. The free AI crawlability checker returns an allowed or blocked verdict for each major AI crawler.

Which GEO metrics should you track?

1. Mention rate: This is the share of AI responses to your tracked prompts that name your brand. If ChatGPT answers 50 of your prompts and names you in 12, your mention rate is 24%. It's the closest thing GEO has to a ranking. Your position inside an answer shifts from run to run, so treat position as a secondary signal.

2. Share of voice: Of all the responses that mention any brand you track, this is the share that mention yours. It shows whether you're gaining ground on competitors or simply benefiting from more coverage of your category.

3. Citation rate: This measures how often AI responses link to your own URLs as sources. A mention shows the model knows your brand. A citation sends readers to your page and tells you which pages are doing the work.

4. Sentiment and positioning: This is how the answer describes you: which strengths it lists, which caveats it adds, and which competitors it groups you with. If a mention labels you "expensive" or "built for enterprise", it can steer the wrong buyers away.

5. AI referral traffic: These are sessions in GA4 from chatgpt.com, perplexity.ai, gemini.google.com, claude.ai, and copilot.microsoft.com. It only captures readers who click through, so it understates AI's influence. Use it as a secondary signal next to the first four.

How do you set up GEO measurement in AIclicks?

1. Add your brand and services: The setup wizard asks for your website, industry, target market, and the services you offer. Each service becomes a topic, and your prompts are grouped under those topics.

2. Build your prompt set: AIclicks reads your site and services, then suggests the questions buyers in your category ask AI assistants. Accept the ones that fit, reject the rest, and add your own one at a time or by CSV upload. Start with 20 to 30 prompts across 3 to 5 topics. Keep that core set fixed between reports so the trend lines stay comparable. Track new prompts from Prompt Discovery under a separate topic.

3. Choose your assistants and markets: Select the models your buyers use from 10 options, including ChatGPT, Perplexity, Claude, Gemini, Google AI Overviews, AI Mode, Copilot, and Grok. Then set your country. State-level tracking is available for the US, Canada, India, and Australia.

4. Let the daily runs build your baseline: AIclicks runs every prompt on every selected model once a day, through each platform's real user interface. Your first answers usually arrive within the hour, and a reliable trend takes shape after 24 to 48 hours.

That's closer to PR than to SEO. Most SEO teams aren't structured for PR.

"The strongest predictor of AI citation share in our dataset isn't the quality of a brand's own content. It's how often the brand appears on third-party pages AI tools already trust. We have customers with high domain authority and excellent content who barely show up in AI answers, and customers with weaker SEO but strong G2, Reddit, and LinkedIn presence who dominate. The mental model of 'better owned content equals better visibility' doesn't survive contact with citation data." - Rokas Stankevicius, Founder, AIclicks

Now, let’s see this in detail.

Where SEO and GEO Actually Diverge

Five differences genuinely change how you plan, budget, and measure. Everything else is overlap dressed up as contrast.

1. There's no rank to climb inside an answer

In Google, position 3 vs position 8 is roughly a 5x click difference. Inside an AI answer that names three brands, "first" vs "third" barely changes the outcome. Both brands got mentioned, the user reads the whole paragraph, and the click-through gap between named brands is far narrower than the gap between position 1 and position 5 in Google.

What this means in practice:

• "Where do we rank in ChatGPT?" is the wrong question. You either appear in ChatGPT or you don't.

• Track mention rate across many runs of the same prompt. That's your actual visibility signal.

• A brand mentioned 80% of the time in third position is winning. A brand mentioned 20% of the time in first position isn't.

2. The query you're optimizing for doesn't exist as a query

When AI tools receive a 23-word prompt, they don't look up that exact string. They run query fan-out: rewriting the user's question into multiple shorter sub-queries and retrieving documents for each.

A prompt like "best GEO tool for a small business" might fan out into half a dozen searches: best GEO tool, GEO tool pricing, GEO tool for SMBs, GEO tool for small businesses, and so on.

Track your competitors: Competitor Discovery finds the brands that already appear in your answers. Track the 3 to 5 that matter most, and Brand Rankings will show visibility, share of voice, and position for each one, filterable by model.

1. Connect GA4 for AI traffic: AIclicks connects to GA4 through a read-only link and splits your AI referral traffic by assistant: ChatGPT, Claude, Gemini, Perplexity, and Copilot. The AI Traffic tab shows sessions, active users, page views, and key events for each one, alongside the pages those visitors land on and their locations, devices, and browsers. You can view the last 7, 30, or 90 days.

3. Review weekly: Check the visibility trend on the dashboard. Then open Prompt Analytics to read the actual answers. Filter Sources to "Mentioned: No" to find pages that cite competitors but not you, and use Sentiment Analysis to see how each assistant describes you. Most actions take 2 to 6 weeks to show up in visibility, so judge results over that window.

Keep Search Console in your stack, but know its limit: Google counts AI Overview and AI Mode traffic inside the regular "Web" search type, so you can't isolate those features there.

How do you win at both SEO and GEO?

Most of the work overlaps, so prioritize the actions that move rankings and AI visibility at the same time:

• Answer one question per page, answer first: A direct answer under a clear heading earns featured snippets in Google and gets lifted into AI answers.

• Keep key pages current: Update facts and show a visible last-updated date. It helps time-sensitive rankings and matches the year-tagged searches AI assistants run.

• Publish comparison and alternatives pages: They rank for high-intent commercial queries and give AI assistants a source when they search for named products.

• Earn mentions along with links: Digital PR, review profiles, and community answers build links for SEO and brand mentions for GEO in the same piece of work.

• Fix technical access once: Make sure key pages are indexed, robots.txt allows both Googlebot and AI crawlers, and important content sits in the HTML.

• Report both side by side: Put rankings and organic traffic next to mention rate and share of voice for the same topics, so one team can see where each channel is gaining or slipping.

Should GEO have its own team?

For most companies, no. Keep GEO with the SEO team and widen its remit.

The on-site work overlaps so heavily that a separate team ends up auditing the same pages and arguing over the same content calendar. What SEO teams usually lack is ownership of the off-site work: community participation, review profiles, YouTube, and PR placements. Give the SEO lead that ownership, a prompt set to report against, and a budget line for outreach.

The one exception is a large brand where PR, community, and SEO already sit in different departments. There, a small GEO function that coordinates between them makes sense, as long as it reports on the same prompt set everyone else uses.

Frequently Asked Questions

1. Is GEO replacing SEO?

No. Google still sends far more traffic to websites than any AI assistant, and Google requires a page to be indexed and eligible for a search snippet before it can appear as a link in AI Overviews or AI Mode. GEO extends SEO into AI answers and adds off-site brand work to the job.

2. What's the difference between GEO, AEO, and SEO?

SEO targets rankings in search results. AEO (answer engine optimization) started as optimizing for featured snippets and voice assistants and is now mostly used to mean the same thing as GEO. GEO targets mentions and citations in answers written by AI assistants such as ChatGPT, Gemini, Perplexity, and Google's AI Overviews.

3. Does good SEO automatically give you good GEO?

Partly. Good SEO handles crawlability, indexing, and on-page quality, which AI search depends on. It doesn't cover how often other sites, communities, and videos mention your brand, and that has a large effect on which brands AI assistants name.

4. Do backlinks matter for GEO?

They matter less than brand mentions. In Ahrefs' study of 75,000 brands, branded web mentions correlated with AI Overview visibility at 0.664, compared with 0.218 for the number of backlinks. Links still help your pages rank, which feeds the retrieval step.

5. How do I know if AI assistants mention my brand?

Build a list of the prompts your buyers ask, run them across the assistants you care about on a regular schedule, and record whether your brand is named or cited each time. You can do this by hand in a spreadsheet for a small prompt set, or use a tracker like AIclicks to run it daily and log the sources behind each answer.
