Picture this: you have a great product or a top-quality service, and your website is packed with relevant, valuable information. You have even invested in "traditional" SEO. Yet when people ask ChatGPT, Gemini, Copilot, or another AI assistant about your industry or your product, your company does not come up at all. Your expertise, your offering — it stays under the radar. That is frustrating, and unfortunately a very common problem if you are not specifically optimizing for Generative Engine Optimization (GEO).
Many businesses unintentionally make mistakes that sabotage their visibility in AI generators. These systems work fundamentally differently from traditional search engines. They do not just scan for keywords; they look for entities, relationships, credibility, and structured answers. Ignoring those differences can cost you dearly. Let's walk through the 7 biggest GEO mistakes and how to avoid them, so your business is the one that shows up at the top of the AI shortlist.
The Big Turn-Offs: 7 GEO Mistakes to Avoid Right Now
1. Keyword Stuffing and Over-Optimization
The mistake: You are still clinging to old SEO tactics, repeating a single keyword dozens of times in the hope that AI picks up your content. Your copy reads unnaturally, is full of repetition, and adds little concrete value. A page about "best dog food in Amsterdam" repeats that exact phrase in every paragraph, while the text barely goes beyond that basic information.
Why it hurts: Generative AI is trained on natural language and the context of a conversation. It immediately recognizes over-optimized content as spammy or low quality. AI is looking for in-depth knowledge and semantic relationships between words and entities — not a simple keyword match. Worse, it may flag your content as untrustworthy.
What to do: Write for people, in natural language. Focus on entities (product names, locations, specific features) and the relationships between them. Use synonyms and related terms. Explain concepts fully. Think about the different ways someone might phrase a question, and answer all of them. The AI is smart enough to make the connection.
2. No Structured Data (Schema Markup)
The mistake: Your website presents information as plain text only. You may have product details, opening hours, reviews, or FAQs, but none of it is structured in a way that is directly machine-readable for AI.
Why it hurts: AI models rely on structured data (Schema Markup) to quickly and accurately grasp the essence of your content. Without schema, AI can still read the text, but it has a much harder time interpreting facts, entities, and relationships unambiguously and reusing them in answers. It is like having a complex database but no index to find the data quickly. Think of a company that offers online training courses but has not marked up course length, certification, and price using Course schema markup.
What to do: Implement the relevant Schema Markup types on your website. For products, use Product with properties such as price, availability, and reviews. For local businesses, LocalBusiness with address and opening hours. For articles, Article, and for frequently asked questions, FAQPage. This helps AI not only understand your content but present it directly in answers.
3. Poor Core Web Vitals and a Painful User Experience
The mistake: Your website loads slowly, shifts around while loading, and is hard to use on mobile. Images are not optimized, servers respond slowly, and the design is not responsive.
Why it hurts: Although generative AI focuses primarily on content, the underlying crawlers (such as Googlebot) still evaluate the technical side of your website. A slow, unstable site with a poor user experience gets a lower rating. AI models build on the "best" information sources, and "best" also means technically sound. If your site is slow, the odds drop that the AI crawler will index it frequently and in depth. You can read more about this in our article on Core Web Vitals and AI crawlers.
What to do: Optimize your Core Web Vitals (Largest Contentful Paint, Cumulative Layout Shift, First Input Delay/Interaction to Next Paint). Make sure you have fast hosting, optimized images, efficient code, and a responsive design. A fast, stable, user-friendly website is the foundation for any form of online visibility, including GEO.
4. A Lack of E-E-A-T (Experience, Expertise, Authoritativeness, Trustworthiness)
The mistake: Your content is anonymous, contains no clear source citations, or is written by someone with no demonstrable expertise. You make all kinds of claims but never back them up.
Why it hurts: Generative AI places enormous value on the credibility and authority of information sources. AI models are trained to minimize "hallucinations" (made-up facts) and to look for the most credible sources. Content without clear E-E-A-T signals is simply less likely to be recommended or used in generated answers, because the AI has no confidence in who is behind it.
What to do: Make sure the authors of your content are experts, and make that visible (author profiles, biographies). Cite sources where relevant. Show customer reviews and testimonials. Give examples of your experience and expertise in practice. This builds trust with people and with AI alike.
5. Unclear, Inconsistent, or Vague Information
The mistake: Your website is a maze of information with no clear structure. Different pages contradict each other, or key concepts are never explained consistently. You use jargon without defining it. (For a Dutch-market example: if you list a KvK number — the Dutch Chamber of Commerce registration number — without explaining what it is, international readers and AI models alike are left guessing.)
Why it hurts: AI excels at distilling concrete answers out of complex text. But if the information on your site is inconsistent, too vague, or full of unexplained jargon, the AI cannot formulate a coherent, accurate answer. It will skip your site in favor of a source that does provide the right answers directly. If your FAQ section, for instance, gives answers that do not match your product pages, both the AI and the user end up confused.
What to do: Aim for absolute clarity and consistency. Use a logical page structure. Write clear, concise answers to likely questions. Use lists, tables, and short paragraphs to present information in a scannable way. Run a content audit to eliminate inconsistencies.
6. No Attention to "Answer-Ready" Formatting
The mistake: Your website is written like a brochure or a long essay, with no sections that directly answer a specific question. You expect the AI to fish the relevant sentence out of a long wall of text by itself.
Why it hurts: Generative AI models are first and foremost answer machines. They are designed to respond to a question directly and succinctly. If your content is not optimized to answer directly — for example, by putting a question in an H2 or H3 followed by a short, clear answer — you are making it unnecessarily hard for the AI. Your content then lacks the "answer snippets" that so often appear directly in AI-generated summaries.
What to do: Write your content in an "answer-ready" way. Think about the questions your target audience asks and answer them explicitly on your pages. Use FAQ sections within your content and make sure the answers are direct and to the point. You can discover more about this in our Practical Guide to AEO.
7. Your robots.txt (Accidentally) Blocks AI Crawlers
The mistake: You have a robots.txt file that blocks (parts of) your site for specific crawlers, or you have a generic rule that unintentionally excludes AI-specific user agents.
Why it hurts: Many generative AI models and their underlying crawlers use specific user agents that differ from the traditional Googlebot. If your robots.txt blocks those user agents, they cannot crawl your content and therefore cannot include it in training data or generative answers. That means complete invisibility for that particular AI.
What to do: Check your robots.txt file. Make sure relevant AI crawlers such as Google-Extended, CCBot (Common Crawl), or specific bots from other AI services can access your content. Be specific about which parts of your site you want to hide and which you do not. A blanket Disallow: / can be fatal. See our Practical Guide to Robots.txt and AI Crawlers for detailed instructions.
The Way Forward: How to Actually Win
Avoiding these mistakes is the first step toward successful GEO. The goal is to transform your website into a trustworthy, clear, and machine-readable source of knowledge. That means:
- Writing for people and machines: Natural, valuable content that is also structured with Schema Markup.
- Technical excellence: A fast, stable, and accessible website.
- Radiating authority: Demonstrating expertise and building credibility.
- Thinking in answers: Offering content that answers questions directly.
- Being open to AI crawlers: Making sure you are technically accessible to all relevant AI bots.
GEO is not a one-time setting but an ongoing process of optimization. By avoiding these common mistakes and optimizing proactively, you position your business as a top source for generative AI and exponentially grow your visibility in tomorrow's digital landscape.
Frequently asked questions
What is the biggest difference between SEO and GEO?
SEO focuses primarily on appearing in traditional search engine results through keywords and links. GEO focuses on optimizing content to serve directly as an answer source for generative AI models and chat interfaces. It is not just about being found, but about being used to formulate answers.
How do I know whether my website is already ready for AI search engines?
You can test this by asking related questions in AI tools such as ChatGPT or Gemini and checking whether your website is cited as a source, or whether information from your site is represented accurately. Also check your Core Web Vitals, your Schema Markup implementation, and your robots.txt file for restrictions on AI crawlers.
Can I do GEO myself, or do I need an expert?
Basic GEO — cleaning up keyword stuffing and improving content clarity, for example — is often something you can handle yourself. For deeper implementation of structured data, complex technical optimizations, and a strategic approach to E-E-A-T, the help of a specialized GEO agency such as WeArkMedia can be extremely valuable.
