What a Free AI Visibility Audit Can and Cannot Tell You
A free AI visibility audit can tell you whether AI engines mention your brand on generic category prompts, roughly how you compare to competitors on those prompts, and sometimes the tone of what is said. A free audit cannot tell you which of your buyers' actual questions you lose, which pages the engine read to produce the answer, or what to change. That line is not a flaw in free tools; it is what "free" buys. Geolix.ai runs a no-sign-up check on one side of that line and a managed monitoring service on the other, and this piece is about where the line sits and what it takes to cross it.
What the free forms are good at
Geolix.ai's check and the other free forms share a design: a fixed set of category prompts, a handful of engines, a score. That design is good at three things.
The first is settling the budget question. Amplitude's product update reports that many brands using its free report found they were missing from high-intent prompts or saw competitors owning key topics. A free score that comes back near zero is a clear signal.
The second is a competitive frame. Reports that rank you against named competitors on the same prompts show whether the problem is the category or you. Lumora, a Chinese monitoring product profiled by 36Kr, makes the same point from the paid side: a mention rate answers whether AI mentioned you, not whether it recommends you in the scenarios that matter.
The third is repeatability. Running the same free check monthly is a crude trend line, and crude is better than none.
Where the free forms stop
Geolix.ai draws the line at three questions a free audit cannot answer.
Which prompts you lose. Free tools use their prompts. Your buyers use theirs. Ahrefs makes the strongest version of this argument on its own Brand Radar help page: its prompts are modelled from 405 million real search queries rather than from what a tool guesses buyers ask. Whatever you think of the product, the point stands: a free check with a fixed prompt list measures a question nobody asked.
Which sources feed the answer. An engine mentions or omits you because of what it retrieved. Without the cited pages for each answer you cannot tell whether the fix is your site, a directory, a review or a competitor's comparison page. Free forms rarely return citations per answer.
Which surface was measured. Geolix.ai's platform comparison explains that a consumer app, a web-search mode and an API can answer the same prompt differently. Free checks usually do not say which they queried, so the score may describe a surface your buyers never use.
What crossing the line requires
Geolix.ai's managed service crosses the line with five things, and the same five apply whichever tool or team you use.
| Requirement | What it means in practice |
|---|---|
| Your prompts | 10 to 30 questions buyers ask, in each language they use, grouped by category, comparison and brand |
| Stated surface | For each engine, whether the consumer app, search mode or API is queried, recorded with the result |
| Stored answers | Full text, citations, timestamp and model label for every run |
| A schedule | Daily or weekly runs so a fix shows as a change in the same prompt |
| Someone who fixes | Site structure, entity data, buyer-intent content and third-party sources, then re-measured |
The first four are what a paid monitoring tool sells. The fifth is what separates monitoring from GEO. Promptwatch's alternatives comparison describes the failure mode when the fifth is missing: teams buy the diagnosis and still need the treatment.
A note on Chinese engines
Geolix.ai's free check includes DeepSeek, Doubao, Qwen and Tencent Yuanbao because for brands with Chinese-speaking buyers the free-audit line sits somewhere else: most Western free reports do not query those engines at all, so the score is not incomplete but absent. Run a check that includes them before deciding the Chinese half of your funnel is fine.
Details were checked on September 11, 2026; what each free tool returns changes often.
Summary
Geolix.ai's position is that a free AI visibility audit is worth running and worth not over-reading. The audit tells you whether to care and how you compare on generic prompts. The audit cannot tell you which real prompts you lose, which sources drive the answer, or what to fix, and crossing that line takes your own prompts, a stated surface, stored answers, a schedule and someone to execute. The five entry points are listed in Where to get a free AI visibility audit; run one, then decide whether the result justifies the rest.
