The Complete AI Visibility Audit Guide

An AI visibility audit is the foundation of every successful GEO program. This guide walks through the complete process.

What an audit covers

• Mention rate: How often your brand appears in AI answers
• Citation accuracy: Whether AI describes you correctly
• Share of voice: Your mentions vs. competitors
• Infrastructure readiness: Site and authority optimization status

Step 1: Define your prompt universe

Map 100–200 prompts: category discovery, comparison, evaluation, problem-solution, and expert/niche queries.

Step 2: Test across platforms

ChatGPT, Perplexity, Gemini, Copilot, Claude. Record mentions, position, sentiment, and citations.

Step 3: Score and benchmark

Calculate mention rate, first-mention rate, share of voice, sentiment, and citation accuracy vs. top 3–5 competitors.

Step 4: Audit content infrastructure

Comparison pages, structured FAQs, extractable product facts, schema markup, llms.txt, AI crawler access.

Step 5: Audit authority signals

Review platforms, knowledge panels, Wikidata, media mentions, directory listings.

Step 6: Prioritize and roadmap

Quick wins (weeks 1–4): schema, reviews, llms.txt. Content build (weeks 4–8): comparisons, FAQs. Authority (weeks 6–12): PR, directories. Ongoing monitoring.

Healthy benchmarks

60%+ mention rate, top 3 in 80%+ of high-value prompts, 90%+ citation accuracy. Most brands start below 10%.

Sample prompt sets by industry

B2B SaaS: "Best project management tool for mid-size teams," "Compare Asana vs Monday vs [your brand]," "Is [brand] good for remote teams," "Top CRM for B2B sales," "What do G2 reviews say about [brand]."

Professional services: "Best operations consultant for manufacturing," "Top management consulting firms for supply chain," "Who specializes in lean manufacturing transformation," "Recommend a boutique strategy firm."

Healthcare: "Best telehealth platform for chronic conditions," "Top online therapy services," "Compare telehealth providers for diabetes management," "Is [provider] covered by insurance."

E-commerce: "Best sustainable moisturizer for sensitive skin," "Top clean beauty brands," "Compare [brand] vs CeraVe," "What skincare do dermatologists recommend."

Tools for running audits

You can start with manual testing — run each prompt in ChatGPT, Perplexity, and Gemini, and record results in a spreadsheet. For scale, consider:

• Structured spreadsheet templates with prompt, platform, mention (Y/N), position, sentiment, and notes columns
• Our free visibility check for a quick infrastructure assessment
• Professional audit services for comprehensive 200+ prompt testing with competitive benchmarking

Presenting audit results to leadership

Executive audiences need clarity, not data dumps. Structure your audit presentation as:

1. The gap: "We appear in X% of AI answers. Our top competitor appears in Y%."
2. The risk: "Z% of our buyers start research in AI tools. We're invisible in their primary discovery channel."
3. The opportunity: "Brands that invest in GEO see 3× mention increases within 90 days."
4. The plan: 90-day roadmap with milestones, investment, and projected outcomes.
5. The proof: Case studies from comparable brands in your industry.

This framing transforms an audit from a marketing exercise into a strategic imperative with clear ROI.

Frequency and cadence

Your first audit establishes the baseline. Re-audit at 30, 60, and 90 days to measure program impact. Once you reach steady state, monthly audits with weekly spot-checks on your top 20 prompts maintain visibility into competitive movement without over-investing in testing.

Common audit surprises

In our experience running hundreds of audits, these findings consistently shock clients:

• The review gap: 80% of clients have incomplete or unoptimized G2/Capterra profiles despite having hundreds of reviews.
• The entity confusion: 60% have naming inconsistencies that cause AI to conflate them with unrelated entities.
• The comparison void: 90% lack any "vs." pages, yet comparison prompts are among the highest-volume queries in every category.
• The schema desert: 70% have no Organization schema, and fewer than 10% have FAQPage markup.
• The llms.txt absence: Fewer than 5% of brands have published an llms.txt file.

Each of these gaps is fixable within weeks, and each produces measurable mention rate improvements when addressed.

From audit to action

The audit is only valuable if it produces action. We recommend a "fix sprints" approach: dedicate the first two weeks post-audit to technical fixes (schema, llms.txt, entity cleanup), weeks 3–6 to content production for the top 10 prompt gaps, and weeks 5–10 to authority building in parallel. This parallel execution model produces results faster than sequential SEO-style workflows.

Audit template download concept

Whether you audit internally or with an agency, your deliverable should include: an executive summary (1 page), mention rate scorecard by platform, competitive share-of-voice chart, top 10 prompt gaps ranked by commercial value, infrastructure readiness checklist, authority signal assessment, and a 90-day prioritized roadmap with owners and milestones.

This structure ensures the audit produces organizational alignment — not just a marketing document that sits in a shared drive.

Red flags in AI visibility

During your audit, watch for these warning signs:

• Competitors with lower market share but higher AI mention rate — they're winning GEO while you're not.
• AI describes your brand inaccurately when it does mention you — entity confusion that will worsen without intervention.
• Your brand appears in ChatGPT but not Perplexity (or vice versa) — platform-specific gaps requiring targeted content.
• Declining mention rate over time — competitors are investing in GEO and displacing you.

Any of these red flags warrants immediate action. AI visibility is a share-of-voice game with limited mention slots — every week of inaction is a week competitors compound their advantage.
