The most common generative engine optimization mistakes are blocking AI crawlers by accident, writing pages that never state a clear answer, ignoring off-site mentions, and measuring AI visibility with one-off screenshots. Generative engine optimization (GEO) is the work of making a brand’s content retrievable, quotable and trusted by AI answer systems such as Google AI Overviews and AI Mode, ChatGPT search, Perplexity, Gemini and Copilot.
GEO builds on SEO rather than replacing it. Most AI answer systems retrieve web pages before writing, so crawlability and relevance still decide whether you are considered at all.
Mistake 1: Blocking the crawlers you want
Some sites added blanket blocks for AI bots in robots.txt, or their CDN’s bot protection blocks them by default. That may keep content out of training data, but it can also keep it out of AI search results.
- Distinguish training crawlers (GPTBot, Google-Extended, ClaudeBot for training) from search and retrieval crawlers (OAI-SearchBot, PerplexityBot, Claude-SearchBot)
- Check Cloudflare or other CDN bot settings, which can block AI crawlers independently of robots.txt
- Test with server logs that the crawlers you allow actually get 200 responses
Google AI Overviews use Googlebot, so blocking Google-Extended does not remove you from AI Overviews; it affects use in Gemini models and grounding.
Mistake 2: Pages that never give a direct answer
AI systems quote passages that answer a question clearly. Many marketing pages circle around a topic with long introductions and vague claims. If the answer to “how long does X take” is buried in paragraph seven, a retrieval system may pick a competitor’s page where it is in the first sentence.
Start sections with the answer, then explain. Use headings that match real questions. Keep definitions, numbers and steps explicit.
Mistake 3: Writing for AI instead of people
Some teams swing too far and produce pages stuffed with question headings and short, repetitive answers aimed at machines. These read badly, and search systems increasingly downrank content that seems mass-produced. Google’s guidance on AI features says the same practices that help people help AI features.
Why do brands with good content still get left out?
AI answers often rely on third-party sources: review sites, comparison articles, forums such as Reddit, industry publications and Wikipedia. If your brand is rarely mentioned outside your own site, models and retrieval systems have little evidence that you belong in an answer.
- Earn coverage in industry publications and comparison articles
- Keep profiles accurate on review platforms relevant to your sector
- Make sure facts about your company are consistent everywhere: name, services, locations
- Take part in genuine community discussions; do not plant fake reviews or posts
Mistake 4: Measuring with screenshots
AI answers vary between sessions, users, locations and days. A screenshot showing your brand in ChatGPT once proves little; one showing it missing proves equally little.
Measure with a fixed prompt set, run repeatedly over time, across several engines. Track the share of runs where you are mentioned and cited, and which sources are cited instead of you. Tools such as Profound, Peec AI, Semrush’s AI toolkit and Ahrefs Brand Radar offer this, or you can build a simple version with APIs.
Mistake 5: Ignoring technical basics
Many AI crawlers do not run JavaScript. If your key content renders only client-side, they may see an empty page. Slow servers, errors and broken internal links also reduce how much gets crawled.
- Serve main content in the initial HTML
- Keep structured data accurate: Organization, Product, Article, FAQ where relevant
- Maintain an XML sitemap with correct lastmod dates
- Fix 4xx and 5xx errors on important pages first
Mistake 6: Expecting quick, guaranteed results
No agency can guarantee a mention in AI answers. Models change, retrieval sources change, and outputs vary. GEO is a set of practices that raise the probability of being cited, measured over months.
How Alien Road applies generative engine optimization
In a typical engagement, our team begins with an AI visibility baseline: a prompt set built from the client’s real customer questions, run across several AI engines repeatedly, recording mentions, citations and competing sources. In parallel we check robots.txt, CDN bot rules, server logs and rendering.
Fixes follow the evidence. Technical blocks come first, then rewriting key pages so answers are explicit, then off-site work on the sources AI engines already cite in the category. Reporting repeats the baseline monthly, so the client sees mention and citation share change over time alongside organic traffic and AI referral traffic in analytics.
How is GEO different from traditional SEO?
The foundations overlap: crawlable pages, relevant content, authority. The differences are in what gets rewarded and how results are measured.
- SEO measures rankings and clicks; GEO measures mentions, citations and the context of the mention
- SEO targets keywords; GEO targets the longer, conversational questions people ask assistants
- SEO focuses on your own pages; GEO depends heavily on what third-party sources say about you
- SEO results are fairly stable day to day; AI answers vary between sessions and need repeated sampling
Treating them as separate programmes usually wastes effort. Most GEO improvements, such as clearer answers, better structured data and stronger off-site reputation, also help regular search.
Mistake 7: Inconsistent facts about your company
If your website says you have offices in three cities, your LinkedIn page says two and an old directory listing says one, AI systems may repeat any of them. Audit the main sources: your site, Google Business Profile, LinkedIn, Wikipedia or Wikidata where applicable, industry directories and review platforms. Correct what you control and request corrections for the rest.
Where to start this week
Write down ten questions customers ask before buying from you. Ask each in ChatGPT, Perplexity and Google AI Mode, three times on different days, and record whether you are mentioned and which sites are cited. Those cited sites are your first list of places to earn a presence.
Repeat the same check monthly with the same questions. Changes in who gets cited are the earliest signal that your work, or a competitor’s, is having an effect.
