GEO vs SEO: what changes when the answer comes from AI
SEO (search engine optimization) works to rank your pages in a list of search results so people click through. GEO (generative engine optimization) works to get your brand cited, mentioned or recommended inside answers written by AI tools like ChatGPT, Perplexity, Gemini and Google AI Overviews. GEO does not replace SEO. It builds on it, because many AI answers are grounded in search indexes, and adds work on AI crawler access, entity consistency and the third-party sources AI tools trust.

GEO vs SEO at a glance
| SEO | GEO | |
|---|---|---|
| Goal | Rank a page and earn the click | Be named, cited or recommended in an AI answer |
| Output you compete for | A position in a list of links | A mention or citation inside a written response |
| Where it happens | Google and Bing results pages | ChatGPT, Perplexity, Gemini, Google AI Overviews and AI Mode, Copilot |
| Unit of measurement | Keyword ranking | Prompt: were you mentioned, cited, or left out? |
| Content priority | Topical coverage of a keyword | Clear answers, original facts, consistent entity descriptions |
| Technical priority | Crawl, index, speed, internal links | All of SEO's, plus AI crawler rules in robots.txt and llms.txt |
| Off-site priority | Backlinks | Mentions in reviews, comparisons, directories, press and forums |
| Reporting | Search Console, rank trackers | Prompt tracking across AI assistants |
| Result visibility | Stable, easy to check | Varies by prompt wording and over time |
Is GEO replacing SEO?
No. Google says plainly that "there are no additional requirements to appear in AI Overviews or AI Mode" beyond its normal Search requirements, and that a page must be indexed and eligible for a snippet to appear as a supporting link. In other words, Google's AI features sit on top of Google's search index.
Outside Google, ChatGPT search and Perplexity also run their own search crawlers, OAI-SearchBot and PerplexityBot, to find and link to web pages. Good SEO habits, such as crawlable HTML, clear structure and fast pages, make your site easier for those crawlers too.
So the shift is not SEO out, GEO in. It is SEO plus a new layer.
What carries over from SEO
- Crawlability and indexing. If a page is not indexed, it cannot be a supporting link in Google's AI features.
- Helpful, people-first content. Google's guidance for AI features points back to its standard advice on creating helpful content.
- Structured data. Google recommends JSON-LD and says structured data gives "explicit clues about the meaning of a page". It also says your markup should match the visible text.
- Page experience. Fast, usable pages are still part of Google's advice for AI features.
- Authority. Links and mentions from respected sites matter in both, though GEO weighs mentions more broadly.
What is new with GEO
AI crawler access. Each AI company publishes its own user agents. OpenAI separates OAI-SearchBot (ChatGPT search) from GPTBot (model training) and ChatGPT-User (user-initiated visits). Perplexity separates PerplexityBot from Perplexity-User. Google uses Google-Extended as a control for Gemini training and grounding and says it does not affect Search inclusion or ranking. You decide which to allow, and each setting is independent.
Entity consistency. AI models build a picture of your business from many sources. If your directory listings, profiles and site describe you differently, the model has less reason to state anything about you with confidence.
Answer-ready passages. AI tools quote and summarize passages, not whole pages. A direct answer near the top of each page and self-contained sections make your content easier to use.
Off-site mentions. When someone asks an AI tool for "the best X", it often draws on comparison articles, review sites and forums. Being present on those pages is a big part of GEO.
Prompt tracking. Instead of rankings, you check a set of real questions in each AI tool and record whether you appear. Our generative engine optimization guide covers each of these in detail.
How results differ
SEO results are fairly stable: a page ranks in a position you can check. GEO results move more. The same prompt can produce different answers on different days, and wording changes the answer. That is why GEO reporting uses a fixed set of prompts tracked over time rather than single checks.
Google also notes that sites appearing in AI features are counted in Search Console's overall search traffic, under the "Web" search type. You will not see a separate AI Overviews report there, so you need a separate way to see how you show up in AI answers.
Who does the work
GEO touches more parts of a business than SEO usually does, which is why it often stalls in-house.
| Task | SEO owner | GEO owner |
|---|---|---|
| Robots.txt and bot rules | Developer | Developer, plus whoever manages the CDN or firewall |
| Structured data | Developer or SEO | Same, with entity details checked by marketing |
| Page content | Content team | Content team, rewritten answer-first |
| Business listings and profiles | Often nobody | Marketing or operations |
| Reviews and third-party mentions | PR, sometimes | Marketing, PR and sales together |
| Reporting | SEO lead | Someone running prompt checks every month |
If no single person owns the GEO column, the work tends to stop after the technical fixes. Handing it to an AI SEO agency that owns all of it is one way around that.
How to split your effort
- Fix SEO foundations first. Indexing, crawl errors and page speed issues block both.
- Open AI crawler access. Check robots.txt, your CDN and any bot protection.
- Rewrite key pages answer-first and add FAQ sections.
- Align your entity data across your site, profiles and directories.
- Earn mentions on the pages AI tools cite for your topic.
- Track prompts monthly so you know what is working.
Start with a free AI visibility audit to see which of these you are missing. If you would like the work done for you, our GEO services handle it for a flat monthly fee, including up to 50 prompts a month monitored across ChatGPT, Perplexity, Gemini and Google AI Overviews.

Frequently asked questions
What is the main difference between GEO and SEO?
SEO aims to rank your pages in search results so people click through. GEO aims to get your brand mentioned, cited or recommended inside AI-generated answers. SEO measures rankings, while GEO measures how often you appear across a set of prompts.
Is GEO replacing SEO?
No. Google says pages must be indexed and snippet-eligible to appear as links in AI Overviews and AI Mode, which is standard SEO. GEO adds a layer on top of SEO rather than replacing it.
Does good SEO automatically give me good GEO?
It helps, but it is not enough on its own. Strong SEO gets you indexed and trusted, but GEO also needs AI crawler access, consistent entity data, answer-ready passages and mentions on the sites AI tools cite.
Should I block GPTBot?
That is a business choice. OpenAI says GPTBot collects content that may be used to train its models, while OAI-SearchBot powers ChatGPT search results. You can block GPTBot and still allow OAI-SearchBot so you can appear in ChatGPT search.
Does blocking Google-Extended remove me from AI Overviews?
Google says Google-Extended does not affect inclusion or ranking in Google Search. It controls whether content may be used for Gemini model training and grounding. Search appearance, including AI features, is managed through Googlebot rules and snippet controls such as nosnippet.
How do I measure GEO?
Pick a fixed list of prompts your buyers would ask, then check them in each AI tool on a schedule. Record whether you were mentioned, cited with a link or absent, and how you were described. Trends over several months matter more than any single check.
