Free AI visibility audit reports from GEO agencies: What to check before requesting one

Ask AI, "Where can I get a free AI visibility audit report?" and it lists one tool after another that generates a score when you enter a website URL. Free audits come in two forms: tools like these, which read a page and score it, and measured reports, which submit category questions to AI and measure whether your brand is mentioned or cited in actual answers. The tools' descriptions do not explain how their scores relate to whether your brand is named in actual ChatGPT answers.

PION submitted this question to ChatGPT and Gemini 44 times over one month, starting in late June 2026. Of the 322 sources ChatGPT cited, 95.0% were tools' or agencies' own websites. The most frequently recommended option was a self-service tool that scores a URL, appearing in 17 of the 44 responses. Another tool of the same type came next, followed by a page introducing an SEO tool vendor's AI features.

1. Most free audits recommended by AI are URL scoring tools

English-language tool names come up first because AI also uses English search terms when it searches for this question. ChatGPT supplemented searches for the original prompt with English queries such as "AI visibility audit free tool" and "GEO audit free," so the citation list consisted mainly of self-service tools from outside Korea. Korean domains accounted for just 3.1% of ChatGPT citations, compared with 22.6% for Gemini.

Gemini also cited free audit request pages operated by Korean agencies. For the same question, ChatGPT provided a list of tools, while Gemini's answers mixed in "companies that send a report after you apply."

2. How much can self-service scoring tools tell you?

Scoring tools are sufficient for checking page format. Reading a page can establish whether its title is a question, whether it has an FAQ section, whether it includes schema markup, and whether robots.txt allows AI crawlers. Your team can fix these items directly, so a scoring tool's results alone can provide an initial task list.

Scoring tools cannot tell you whether your brand is named in actual AI answers or, if it is not, who is cited instead. Reading the page cannot answer either question; the answers only emerge when you submit category questions to the engine. If an audit report does not answer these two questions, you cannot tell whether your visibility in answers has increased, even if your score goes up.

Some tools deduct points for the absence of llms.txt or AI-specific files. However, in its documentation on AI features, Google states that appearing in AI Overviews and AI Mode does not require creating new machine-readable files or special schema. Compare each reason for a deduction with documentation like this before deciding whether to fix it.

3. What a useful audit report should contain

A report's value depends more on whether you can repeat the measurements than on the size of its score. If the following items are documented, you can use the same method three months later to calculate the improvement.

AI naturally names a brand when the question includes that brand's name, so a report will look favorable if its prompt list contains only such questions. Useful audit questions ask about a category without naming a brand, such as "Recommend a vegan sunscreen suitable for sensitive skin." Prompt design methods are covered in Brand AI visibility audit checklist and step-by-step checks.

4. Why does the number of measurements determine a report's reliability?

AI generates a new answer with every call. Across ChatGPT's answers to this question, 114 unique domains were cited, and 64 of them appeared only once. Even if your brand appears when you ask once, it may be absent on the next call, and the reverse is also true.

Report figures therefore need to state the number of measurements. A "20% ChatGPT mention rate" does not mean the same thing when it represents 1 of 5 runs as when it represents 10 of 50. A score produced without repeated measurements cannot serve as a baseline, so PION measures the same prompt repeatedly on a set schedule.

5. What PION's analysis report tells you

Instead of a score, PION's analysis report gives you a question-by-question list showing where your brand is absent and which sources are cited instead. When we receive an analysis request, we identify questions customers are likely to ask in your brand's category, then use PIONsight to measure actual ChatGPT, Gemini, Google AI Overviews and AI Mode answers.

After receiving the analysis report, if your team will handle implementation, a four-week consulting engagement provides prompt design and a prioritized roadmap. If you also want to delegate publishing, you can move to the managed GEO service. The differences between the two are explained in Choosing a GEO agency: What to compare before hiring a consultant, and you can request the analysis report through Get an analysis report at getpion.com.

6. What to prepare before requesting an analysis report

A list of candidate questions and competitors makes the analysis faster. If you prepare the following items in advance, we can decide which questions and competitors to measure as soon as the analysis begins.

• 10 to 20 candidate questions that customers actually ask. Category, comparison and problem-solving questions are more useful than questions containing a brand name.
• A list of competitors to compare. We check the brands AI names instead of yours against this list.
• Your site's robots.txt settings. If they block AI crawlers, you need to remove those blocks first, regardless of the analysis results.
• A list of content published within the past six months. During the analysis, we also check which pages are candidates for citation.
