When people look for an agency, a product or a service today, they no longer just type into Google; they ask ChatGPT, Gemini, Perplexity or Copilot. Google itself answers directly at the top of the results with AI Overviews and AI Mode. Brands that are not mentioned in these answers lose visibility, even if they rank well in the classic results.
That is why a new concept has joined SEO: GEO (Generative Engine Optimization), the work of becoming visible in AI-powered search. In this guide we explain what GEO is, how it differs from SEO and the concrete steps you can take so that AI answers cite your website as a source.
What Is GEO and How Is It Different from SEO?
The goal of SEO is for your page to rank high in search results. The goal of GEO is for AI assistants to mention your brand and cite your website when they answer a question.
The good news: GEO does not replace SEO; it builds on it. Most AI search systems draw on search indexes when generating answers. Google states that there is no special markup or separate index for AI Overviews and AI Mode, and that core SEO practices apply there too. In other words, a site that cannot be crawled, is not indexed or loads slowly will struggle to appear in AI answers as well.
1. Make Sure AI Crawlers Can Reach Your Site
The first step is technical: a system that cannot read your site will not recommend you. The main crawlers to know:
- OAI-SearchBot: Crawls sites for ChatGPT’s search feature. Blocking it reduces your chances of appearing in ChatGPT search answers.
- GPTBot: The crawler OpenAI uses for model training. Blocking it does not remove you from ChatGPT search; the two are managed separately.
- Google-Extended: Controls whether your content may be used to train Gemini models. It does not affect your visibility in Google Search.
- PerplexityBot, ClaudeBot and Bingbot: Crawlers used by other AI search and assistant services.
Check your robots.txt, but do not stop there. On many sites the real barrier is not robots.txt but the hosting provider’s firewall or the CDN’s bot protection. Always check your server logs for 403 or 429 errors returned to these crawlers.
2. Write Content That Answers Questions Directly
AI assistants like to quote paragraphs that answer a question clearly and concisely. Structure your content accordingly:
- Start each section with a question and give the direct answer in the first one or two sentences; expand on the details afterwards.
- Choose H2 and H3 headings based on the questions users actually ask.
- Explain step-by-step processes with numbered lists and comparisons with tables.
- Add a short “Frequently Asked Questions” section at the end of the page.
- Give concrete information instead of generic statements: price ranges, timelines, figures and real project examples.
3. Describe Your Brand in a Way Machines Understand
AI systems recognise your brand from consistent signals. Your brand name, address, phone number and what you do should read the same on your website, your Google Business Profile, your social media accounts and industry directories.
Schema.org structured data helps here. With Organization (or LocalBusiness) markup you can describe your company, with sameAs your official social profiles, and with BlogPosting the author and date of your articles. Structured data alone does not guarantee citations, but it helps your content be understood correctly. Remember: the markup must match exactly what is visible on the page.
4. Show Your Expertise and Trustworthiness
Both Google and AI assistants favour content based on experience and coming from trustworthy sources. To get there:
- Publish case studies that show your work with real projects, screenshots and results.
- Back up the claims in your articles with official sources and data.
- State your team, founding year and areas of expertise clearly on your About page.
- Strengthen off-site signals such as customer reviews and mentions in industry publications.
5. Keep Content Fresh and Notify Search Engines Quickly
AI answers value freshness. A page titled “2024 prices” will not be recommended to someone asking in 2026. Update your key pages regularly and show the date of the update.
To notify search engines quickly about new or updated pages, keep an up-to-date XML sitemap and support the IndexNow protocol. IndexNow instantly passes changed URLs to search engines such as Bing and Yandex, and Bing’s index is also among the sources some AI assistants rely on.
6. Do You Need an llms.txt File?
llms.txt is a proposal for a text file placed at the root of your site that summarises your most important pages for AI systems. It is not an official standard yet, and Google has said it does not use it. Since it takes only a few hours to prepare, it does no harm, but do not make it the centre of your GEO work. The real impact comes from crawlable, clear and trustworthy content.
7. Measure the Results
To see the effect of your GEO work:
- In Google Analytics, track traffic from sources such as chatgpt.com, perplexity.ai, gemini.google.com and copilot.microsoft.com as a separate channel. ChatGPT usually adds the utm_source=chatgpt.com parameter to the links it gives.
- Define 10–20 key questions about your industry, ask different assistants regularly and record whether your brand is mentioned.
- Follow impressions and clicks for your pages in Search Console; visibility in AI Overviews is included in this data.
Frequently Asked Questions
Do I need a separate website or separate content for GEO?
No. The same pages work for both classic search and AI answers. What matters is that your content is clear, current, well structured and technically accessible.
What happens if I block AI crawlers?
If you block search crawlers (such as OAI-SearchBot), your chances of appearing in that assistant’s answers drop. Blocking crawlers used only for model training (such as GPTBot or Google-Extended) does not directly affect your search visibility. Make each decision separately, based on your business goals.
How long does it take to see GEO results?
Once technical barriers are removed, the effect can show within a few weeks. Content and brand authority, as with SEO, build up and pay off over months.
