How to Do a GEO Audit: Step-by-Step Guide

How do you measure your brand's visibility in ChatGPT, Claude, Gemini, and Perplexity? Most companies approach this question with assumptions — "we're probably fine" or "nobody's searching for us there." Both are dangerous. A GEO audit is the only way to establish an objective baseline.

What Is a GEO Audit?

A GEO audit is a systematic analysis of how your brand is represented across generative AI engines. It can be done manually — with real limitations — or professionally, with broader query sets, competitor benchmarking, and statistical confidence. This guide walks you through the steps to conduct a basic manual audit for your brand.

Step 1: Select Representative Queries (10-15 Questions)

The quality of your audit depends entirely on your query selection. A strong query set covers these categories:

• Category queries: "What's the best [your service] for [target customer type]?"
• Problem-solution queries: "I need [specific outcome] — who should I work with?"
• Comparison queries: "What's the difference between [your brand] and [competitor]?"
• Direct brand queries: "What do you know about [brand name]?"

Select 3-4 queries per category. Focus on questions your actual customers ask — think from the buyer's perspective, not your marketing department's.

Step 2: Systematic Testing Across 4 Engines

Run each query through ChatGPT, Claude, Gemini, and Perplexity in sequence. For each test:

• Use the exact same question — do not paraphrase between engines.
• Copy the complete response, not just the first few lines.
• Note the time — some engines use real-time data that varies by session.
• On Perplexity, record which sources are cited.

Step 3: Record and Score Responses

Evaluate each response against four criteria on a 0-3 scale:

• Mention (0/1): Is your brand referenced at all?
• Position (1-3): First mention, middle of list, or last?
• Accuracy (0-3): Is the description correct? Right category? Right features?
• Sentiment (0-3): Positive, neutral, or negative positioning?

Enter this into a spreadsheet: queries as rows, engines as columns, total score per cell (max 10). This table is the foundation of your cross-engine comparison.

Step 4: Competitor Benchmarking

Run the same query set for your top competitors. The goal: compare average scores across engines. Where a competitor outperforms you, analyze why:

• Do they have a Wikipedia or Wikidata page?
• Are they featured more frequently in industry publications?
• Is their schema markup more comprehensive?
• If they dominate a specific engine, what does that engine prioritize?

Step 5: Pattern Recognition

With all responses in front of you, look for patterns. Ask yourself:

• Which signals are working? (When you are cited, what content type is the likely source?)
• Which engine shows your weakest performance, and why?
• Is your brand described consistently, or does the description shift across engines?
• Which competitor dominates which query types?

Step 6: Interpret Your Results

Use your average score to assess your GEO position:

• 7-10: Strong representation. Shift to optimization and ongoing monitoring.
• 4-6: Mid-range. Gaps exist in specific engines or query categories. Prioritize accordingly.
• 0-3: Critical gap. Start with foundational infrastructure: schema markup, Wikipedia presence, citation network.

The Limitations of Manual Audits

This guide gives you a solid starting point. But understanding its limitations is important:

• 15 queries vs. 47 queries produce meaningfully different statistical confidence.
• AI responses vary by session context, geographic location, and current model version.
• Manual competitor coverage is typically limited to 2-3 rivals; professional audits cover 12 or more.
• Identifying which specific signals drive which outcomes (causal analysis) is extremely difficult manually.

A professional GEO audit closes these gaps: 47 queries, 4 engines, 12+ competitors, statistical significance testing, and a prioritized 30-page action plan. When your manual audit surfaces inconsistencies or unexplained patterns, that's the signal that professional analysis is the right next step.
