How to Test If Your Brand Appears in ChatGPT, Gemini, and Perplexity: The Manual Protocol

Quick Answer

You don't need a $500/month tool to test AI brand visibility. A systematic manual testing protocol — run consistently every 30 days — gives you the core data to track progress and identify optimization priorities. Here's the exact protocol Magna uses with new clients.

Before you can optimize for AI visibility, you need to know where you stand. Most businesses have no idea whether they appear in ChatGPT, Perplexity, Gemini, or Claude — or if they do, how they're described, what position they hold, and what competitors are mentioned alongside them.

Paid tools like Profound and Otterly.ai automate this tracking at scale. But for businesses starting out — or anyone who wants to understand the data firsthand — the manual protocol below provides the same core insight at zero cost. Magna uses this as the first step with every new client.

Step 1: Develop Your Query Set (20–25 Queries)

Your query set should represent how your target customers actually prompt AI assistants — not how you wish they would. Most people ask AI for recommendations in one of three ways:

The Three Query Types — Template Examples
Category Queries (5–8)
  • "What [your service type] do you recommend in [your city]?"
  • "Best [your service type] for [your target customer]"
  • "Top [your service type] agencies in 2026"
Comparison Queries (5–8)
  • "Which [your service type] company should I use for [specific use case]?"
  • "[Your service type] vs. [alternative] — what do you recommend?"
  • "[Competitor name] or [your niche] — which is better for [use case]?"
Problem-Solution Queries (5–8)
  • "I need [specific outcome] — which [your service] should I use?"
  • "How do I [solve specific problem] — any recommendations?"
  • "What's the best way to find a [your service type] for [specific scenario]?"

Document your full query set in a spreadsheet before testing. This ensures consistency across platforms and months.

Step 2: The Testing Procedure

For each query in your set, run the test across all four major platforms. Use incognito/private browsing mode to avoid personalization bias from previous sessions.

Platform Version to Test Data Type Key Note
ChatGPT Free (GPT-4o) + Plus (with search) Training data + live web Results can differ significantly between versions
Perplexity Default (web search) Live web retrieval Check sources cited — they reveal what's being retrieved
Google Gemini Gemini 2.0 Flash/Pro Training data + Google index Most correlated with Google KG presence
Claude Claude.ai (free) Training data More conservative with specific brand recommendations

For each query-platform combination, document these seven data points:

  1. Date of test
  2. Exact query used
  3. Platform and version
  4. Brand presence — Yes/No, and if yes, what position (first, second, mentioned in passing)
  5. Exact description used — screenshot the exact text
  6. Competitors mentioned — list every brand that appeared
  7. Overall sentiment — positive, neutral, or negative framing of your brand

Step 3: Competitor Gap Analysis

For every query where a competitor appears and you don't, this is your highest-priority optimization signal. The analysis question is: what do they have that you don't?

Gap Analysis Framework
Check Their Publication Coverage

Are they cited in trade publications you aren't? Industry blogs, news sites, research reports?

Check Their Review Volume

Do they have significantly more Google, Trustpilot, or industry platform reviews?

Check Their Content Depth

Do they have 30+ articles on the topic vs. your 3? More original data, case studies, research?

Check Their Schema Markup

Do they have Organization, FAQ, or Article schema you're missing? Use Google's Rich Results Test.

Each gap you identify becomes a prioritized action item in your AEO program. The most common gaps are review volume, third-party media mentions, and content depth on specific subtopics.

Step 4: Tracking Trends Over Time

A single snapshot tells you where you are. Monthly tracking tells you whether your AEO efforts are working. Build a simple spreadsheet with these columns and run the protocol every 30 days:

AI Visibility Tracking Spreadsheet — Column Headers
Date | Query | Platform | Brand Present (Y/N) | Position | Sentiment | Competitors | Notes

Month-over-month, you're looking for:

Step 5: From Data to Action

Every monthly test produces a prioritized action list. Use this decision framework to triage:

Finding Root Cause Priority Action
Not appearing anywhere Entity not recognized by AI Entity foundation: GBP, Wikidata, Organization schema
Appearing in Perplexity, not ChatGPT Training data gap, not real-time gap Build third-party mentions for next training cycle
Described inaccurately Entity data is unclear or inconsistent Audit and align brand descriptions across all platforms
Mentioned third, competitors first Competitors have more corroborating signals Increase review velocity, media mentions, content depth
Not appearing for local queries Local entity signals weak GBP optimization, local citation building, LocalBusiness schema

Frequently Asked Questions

How do I test if my brand appears in ChatGPT?+
Open ChatGPT in incognito mode and run queries your target customers would use: "What [your service] do you recommend in [your city]?", "Who are the best [your service] companies for [your use case]?", and "Which [your service] should I use in 2026?" Document whether your brand appears, what position it's mentioned, how it's described, and which competitors appear. Repeat monthly with the same query set to track progress.
Do I need to test ChatGPT Free vs. ChatGPT Plus separately?+
Yes — ChatGPT Free (GPT-4o) and ChatGPT Plus with web search enabled can return different results. Free ChatGPT uses the base model trained on historical data. ChatGPT Plus with browsing enabled retrieves live web results. For complete visibility, test both. Your brand may appear in one but not the other, which indicates where your optimization gaps are.
Why should I use incognito mode for AI visibility testing?+
Some AI platforms personalize results based on your previous interactions. If you've mentioned your brand before in a ChatGPT session, the model may recall it. Using incognito mode prevents session-based personalization and gives you results closer to what a first-time user would see — which is your true AI visibility baseline.
What should I document in my AI visibility test?+
For each query and platform, document: (1) Date of test, (2) Exact query used, (3) Platform (ChatGPT Free/Plus, Perplexity, Gemini, Claude), (4) Whether your brand appears (Y/N), (5) Position in response (first, second, third, mentioned but not recommended), (6) Exact description used, (7) Competitors mentioned, (8) Overall sentiment toward your brand if mentioned. Screenshot every response for the full record.
How long does it take to see changes in AI visibility?+
Changes to AI visibility typically take 60-90 days for base-model AI systems like ChatGPT's standard mode, which rely on training data that updates on a multi-month cycle. For real-time retrieval systems like Perplexity and ChatGPT Search, changes can appear within days of publishing new content or earning new citations. Test monthly to catch improvements as they happen.
How many queries should I include in my testing set?+
20-25 queries is the recommended set size. Include at least 5 category queries, 5 comparison queries, and 5 problem-solution queries. Rotate 5-10 queries per month to maintain freshness while retaining enough consistent queries to track trends over time.
