GEO Audit in 30 Minutes: How to Check Your AI Visibility

Why most business owners don't know whether AI models know them

When your potential customer has a question today, more and more often they no longer type it into Google—they type it straight into ChatGPT, Perplexity, or Gemini. The answer they get isn't a list of links—it's a fully formed recommendation. And either you show up in it, or you simply don't exist.

The problem: most business owners still optimize their visibility for a world in which Google is the front door. SEO rankings, backlinks, meta descriptions—all important, but no longer enough. AI models draw their answers from different sources and follow a different logic than search engines.

A concrete example: someone asks ChatGPT for "a good tax advisor for freelancers in Munich". The model names three. None of them has the top Google position—but all three are well documented on Wikipedia, in trade articles, on review platforms, and in structured data sources that AI systems favor during training and web research.

Generative Engine Optimization (GEO) is the field that deals with exactly this. And the first step isn't an expensive tool or an agency—it's a simple audit you can run yourself today in 30 minutes.

The 5 AI models you should deliberately query for your audit

Not every AI model works the same way. For a meaningful audit, you need coverage across the most important systems. These five are relevant right now (as of July 2026):

1. ChatGPT (GPT-4o with web search)

The market leader by usage, especially in business settings. Turn on the web search feature—without it, the model answers from its training data cutoff and delivers outdated or hallucinated results. With search enabled, it's considerably more accurate and valid for your audit.

2. Perplexity AI

Perplexity is a real-time search engine with an AI layer. It shows sources and cites them directly. For GEO, that's especially valuable because you can see where the information about you (or your competitor) comes from.

3. Google Gemini (with grounding)

Google's own model has direct access to the Google index. If you're well positioned in Google, you have an advantage here—but Gemini weights things differently than classic search. Featured snippets and structured data play a bigger role.

4. Claude (Anthropic)

Strong in analytical work, and growing as a business tool. Claude doesn't have persistent web browsing, but it's integrated heavily into other products via API—which means your presence in well-documented, structured sources counts for a lot here.

5. Microsoft Copilot

Copilot is integrated into Windows, Office, and Bing, making it the daily AI touchpoint for many business owners. It uses Bing data and Bing indexing as its foundation.

You don't need to be perfectly visible on all five. But you should know where you stand—and where your competitors are more visible than you.

Step by step: your GEO audit in 30 minutes (with a template)

Open a spreadsheet (Excel, Notion, Google Sheets) and create these columns: Model | Question | Am I mentioned? | How? | Sources (in Perplexity). Then work through three types of questions.

Step 1: Brand queries—5 minutes

Ask about yourself directly. Try variations of your name, your company name, and your product name. Examples:

• "What do you do, what is [company name]?"
• "Do you know [your name] from [city/industry]?"
• "What does [company name] offer?"

Note whether the model knows you, what it says, and whether the details are correct. False information (hallucinations) is its own type of red flag and calls for its own measures.

Step 2: Category queries—10 minutes

Ask the way a customer who doesn't know you yet would ask. Replace the placeholders with your actual niche:

• "Which [your service] providers do you recommend for [target audience]?"
• "What are good alternatives to [competitor]?"
• "Who do you recommend for [specific problem] in [region]?"

Do you show up in the answers? If not: who does show up, and why might that be?

Step 3: Problem queries—10 minutes

Frame questions around the concrete problems you solve. This is where GEO shows its strongest effect—customers ask AI models for solutions, not for providers:

• "How can I tackle [problem you solve]?"
• "What helps with [your audience's pain point]?"
• "What methods are there for [your field]?"

If your content, your name, or your company doesn't appear in these answers, you're missing presence exactly where buying decisions begin.

Step 4: Evaluation—5 minutes

Count: across how many of the models you queried are you mentioned at least once? That's your GEO baseline. Anything under 2 out of 5 models is a clear signal that action is needed.

Spotting red flags and taking the first immediate steps

Not every weakness in the audit needs the same fix. Here are the most common problem patterns and what you can do about them right away:

Red flag 1: You aren't mentioned at all

This is the most common case for small and medium-sized businesses. AI models don't know you because too little is written about you—externally, in a structured way, and repeatedly.

• Create or complete entries in structured directories: Google Business Profile, industry directories, review platforms (Trustpilot, Proven Expert, Yelp).
• Publish expert articles on external platforms (LinkedIn Articles, Medium, guest posts in industry media)—not just on your own website.
• Use structured data (Schema.org) on your website: Organization, Person, FAQPage, LocalBusiness. This is machine-readable knowledge.

Red flag 2: The information about you is wrong

The model knows you but describes you incorrectly—wrong location, wrong services, outdated offering. This is often more dangerous than not being mentioned at all.

• Check and correct all external data points (directories, press mentions, partner pages).
• Create a precise, well-structured About page on your website that clearly and unambiguously describes who you are, what you offer, and for whom.
• Build a Wikipedia page (if you meet the notability criteria) or make sure Wikidata entries exist for your company.

Red flag 3: Competitors are consistently favored

You exist in the answers, but you're never the first recommendation—your competitors always come first.

• Use Perplexity to analyze which sources are cited for your competitors. Those are the platforms where you need to build a presence.
• Produce more citable content: studies, statistics, definitions, how-tos—things that others link to and cite.
• Build mentions in editorial media (not advertising, but genuine editorial mentions in trade publications).

Red flag 4: Only one model knows you

You're visible in ChatGPT but not in Perplexity or Gemini. That means your presence hangs on a single source.

• Diversify your source base. Improve Bing visibility (relevant for Copilot), strengthen Google quality signals (relevant for Gemini).
• Make sure your website is technically clean and crawlable and that no robots.txt block is active for AI crawlers (known bots: GPTBot, PerplexityBot, ClaudeBot, Google-Extended).

Your GEO audit checklist

1. Create a spreadsheet with columns: model, question, mentioned (yes/no), content of the mention, sources.
2. Run brand queries across all 5 models (ChatGPT, Perplexity, Gemini, Claude, Copilot).
3. Formulate category queries from the customer's perspective and run them.
4. Run problem queries for your target audience's top 3 pain points.
5. Determine your GEO baseline: how many of the 5 models mention you at least once?
6. Identify red flags: not mentioned / false information / competitors favored / single source.
7. Check directory entries and create any that are missing (Google Business, industry directories).
8. Check your Schema.org markup—at least Organization or LocalBusiness on the homepage.
9. Analyze external sources (via Perplexity) that are cited for competitors.
10. Check robots.txt: are AI crawlers being blocked unintentionally?
11. Repeat in 60 days—GEO isn't a one-time audit but an ongoing process.
