In short: GEO optimization (Generative Engine Optimization) means adapting your website and content so that ChatGPT, Google AI Overviews, Perplexity and other AI search tools mention your company and cite your site. In a study published at the KDD conference in 2024, adding source citations, quotations and statistics increased a page’s visibility in AI answers by up to 40%. GEO optimization does not replace SEO: AI search relies on the same indexes but prefers clear facts, an answer at the top and companies that are mentioned elsewhere too.
Customers increasingly ask ChatGPT “who builds good websites in Tallinn?” or “which accounting firm in Tartu suits a small business?” and get one answer with 3–5 recommendations. If your company is not in that answer, the customer never reaches your website, even if you are on page one in Google. This article explains what GEO optimization is, how it differs from SEO and 7 steps an Estonian company can take this month.
What is GEO optimization?
GEO stands for Generative Engine Optimization. Researchers from Princeton, Georgia Tech and IIT Delhi coined the term in 2023, and their paper was published at the KDD conference in 2024. They tested which text changes help a source stand out more in AI answers. Citing sources, adding quotations and adding statistics worked best, raising visibility by up to 40%. Repeating keywords did not improve visibility.
Put simply: SEO helps your page get into the list of search results, GEO optimization helps your company get into the AI answer itself.
How is GEO optimization different from SEO?
| SEO | GEO optimization | |
|---|---|---|
| Goal | A position in Google results | A mention and citation in an AI answer |
| Where | Google, Bing | ChatGPT, Google AI Overviews and AI Mode, Perplexity, Copilot, Gemini |
| Unit | A whole page | A paragraph, fact, table or number |
| Success metric | Ranking, clicks | Mentions, citations, visits from AI |
| Trust | Links, authority | Facts, sources, mentions on other sites |
| Foundation | Technical health, speed and quality content are shared by both | |
Google itself says there are no extra technical requirements to appear in AI Overviews and AI Mode: normal SEO best practices apply. So GEO optimization is an extension of SEO rather than a replacement. We compared them in more detail in AI visibility vs SEO.
Why does GEO optimization matter for Estonian companies?
- AI use is growing fast: according to Statistics Estonia, 22% of Estonian enterprises used at least one AI technology in 2025, 8 percentage points more than a year earlier. AI is most often used in sales and marketing. The same is true of customers: they find suppliers with AI.
- There is little Estonian-language content: when AI answers in Estonian, it chooses from far fewer sources than in English. A clear, fact-rich Estonian page therefore has a relatively bigger chance of being used.
- Three languages: people in Estonia ask AI in Estonian, Russian and English. A company with three solid language versions appears in three answers, not one.
GEO optimization in 7 steps
1. Open your site to AI crawlers
If robots.txt or Cloudflare blocks OAI-SearchBot, PerplexityBot or Claude-SearchBot, those AI search tools cannot read your site. Check your settings with our guide to opening your site to AI crawlers and work through the full AI visibility checklist.
2. Put the answer first
AI looks for a paragraph that answers the question directly. Start every service page and article with 2–4 sentences answering the main question: what it is, who it is for, what it costs and how long it takes. Write headings as questions. More examples in content that AI cites.
3. Add facts, numbers and sources
This is the study’s main finding. Replace vague claims (“we are experienced”) with verifiable facts: year founded, number of projects, price range, timelines, warranty. Cite sources such as Statistics Estonia, Google documentation or the law. Use tables, which AI reads and reuses well.
4. Add structured data
Schema.org markup (Organization, LocalBusiness, Service, FAQPage, Article) describes who you are and what you offer in machine-readable form. Guide: schema markup for AI visibility.
5. Keep company details identical everywhere
AI checks whether the same information appears across sources. Your name, address, phone, registry code and services must match on your website, Google Business Profile, the Business Register, LinkedIn, Facebook and directories. Contradictions (an old address, a different phone number) reduce trust.
6. Earn mentions on other sites
AI recommends companies that others talk about: Google reviews, Estonian media, industry associations, partner websites, comparison articles and forums. Ask happy clients for reviews, give expert comments, speak at events and publish case studies with results.
7. Create pages AI wants to cite
AI most often uses pricing pages, comparisons and FAQs because they answer buying questions directly. See the 3 pages you need and refresh old posts: updating old articles for AI search. You can also add an llms.txt file, but it is secondary.
How do you measure GEO optimization results?
- Manual tests: write 10–20 questions a real customer would ask (in Estonian, Russian and English) and ask them monthly in ChatGPT, Perplexity, Gemini and Google AI Mode. Note whether your company is mentioned and linked.
- Google Analytics 4: watch referrals from chatgpt.com, perplexity.ai, gemini.google.com and copilot.microsoft.com.
- Search Console: Google counts clicks from AI Overviews and AI Mode in the normal search report; there is no separate report.
- Enquiries: ask new clients how they found you. “ChatGPT recommended you” is already a common answer.
How quickly does GEO optimization work?
Technical fixes, such as allowing crawlers, take effect within days or weeks once the AI search tool re-reads the page. Content and mentions usually show results within 1–3 months. Getting into model training data takes longer, because models are updated less often. So start with what AI search reads in real time: your website content, your Google Business Profile and reviews.

Frequently asked questions
What is GEO optimization in short?
Adapting your website and content so that AI search tools such as ChatGPT, Google AI Overviews and Perplexity mention your company and cite your site.
Does GEO optimization replace SEO?
No. AI search uses the same indexes and prefers technically sound, fast pages with good content. GEO adds the facts, structure and mentions AI needs on top of SEO.
Does GEO optimization work in Estonian?
Yes, and with little Estonian content available, competition is lower than in English. What matters is that every language version is substantive, not a machine translation.
Can I pay for ChatGPT to recommend my company?
You cannot buy an organic recommendation. ChatGPT and Google AI Mode show ads, but they are labelled and separate. See our article on AI advertising.
How much does GEO optimization cost?
It depends on your site. Technical checks and fixes are a one-off job; growing content and mentions is ongoing. A free audit shows where to start.
