Ask ChatGPT, Gemini or Perplexity to recommend a vendor in your category right now. If your company doesn't come up, the deal was already lost before your sales team ever heard about it. That is the buying decision behind this article: whether it's worth running a free 30-second scan to find out where your business actually stands with AI answer engines before spending a dollar on fixing it.
What Is the AEO Auditor Free Scan, and What Decision Does It Answer?
The UDomain AEO Auditor is a free diagnostic tool that scores how well ChatGPT, Google AI Overview, Perplexity, Claude and Gemini can find, read and cite your website. It answers one specific question: is your business structurally invisible to the AI systems your customers are now asking for recommendations, and if so, exactly where is the breakdown.
This matters because the decision it supports isn't "should we care about AI search" — most enterprise leaders already do. It's "do we know our actual exposure before we brief an agency or a dev team," and that answer currently costs nothing to find out.
Why Does AI Visibility Matter More Than Google Ranking Alone in 2026?
Answer Engine Optimisation (AEO) targets AI engines so your content can be quoted directly as the answer, even when the user never clicks through. SEO alone no longer captures how a growing share of B2B buyers research vendors.
The gap between being cited and not being cited compounds quickly. According to the AEO Auditor's own benchmark data, missing citations cut a site's AI mention rate by 78%, while completing structured schema markup is projected to lift AI citations by 40% to 60%. For a department head evaluating vendors on behalf of the board, that is the difference between appearing in the shortlist an AI assistant generates and not existing in it at all.
How Long Does the Scan Take, and Do You Need a Credit Card?
The scan is completely free, requires no credit card and no account creation. Most sites generate a full interactive dashboard in under 30 seconds; more complex enterprise sites with deep page structures may take up to 60 seconds.
You enter a URL and the report builds live on the page. An email is only requested if you want the full dashboard sent to you or want a follow-up analysis — there is no charge or auto-billing tied to providing it.
What Exactly Do You Get in the Free Report?
The report covers four modules: an overall AI Visibility Score benchmarked against your industry average, an AI Copy Signals assessment of citation quality and conversational tone, 172 individual structure checks spanning schema markup and technical crawlability, and a prioritised action plan ranked by expected score impact.
A sample scan in the tool's own demo shows an 85/100 visibility score, 12 points above the industry average, with a full breakdown of platform presence across channels like Reddit, X and Wikipedia, plus a pass/fail count across the 13 core citation checks. That level of specificity is what separates a genuine diagnostic from a marketing quiz.
What Happens After the Free Scan Ends?
Nothing is charged automatically, and there is no subscription trap. The free scan is a standalone diagnostic you can rerun as often as you like. If your team wants help acting on the action plan, the natural next step is a paid implementation consultation, where a specialist walks through the specific fixes and their expected timeline.
That timeline matters for planning: structural fixes are typically re-crawled by AI engines within 2 to 4 weeks, while citation and authority signals take 1 to 3 months to accumulate. Rescanning monthly is the recommended cadence to track whether your score is actually moving.
How Does This Compare to Assessing AI Visibility Manually?
Manually checking AI visibility means prompting five different AI assistants with dozens of realistic buyer queries, then cross-referencing whether your site, your competitors, or neither gets cited — a task that takes an analyst days, not seconds, and produces no structural diagnosis of why the citations are missing.
The Auditor compresses that into one pass and adds the layer manual testing can't easily replicate: 172 automated structure checks against known AEO standards, from JSON-LD coverage to internal linking depth, which the tool's own data shows runs at roughly half the industry average on a typical unoptimised site.

What Are the Honest Limitations of a Free AEO Scan?
The scan diagnoses; it does not implement. Fixing schema markup, rewriting copy for citability, and building internal linking structure still requires either an in-house development team or paid specialist support — the free report tells you precisely what to fix, not who will fix it for you.
The reported averages, such as the roughly 80% visibility lift many sites see after AEO work, are aggregate figures across scanned sites, not a guarantee for any specific business, and results depend heavily on how much of the action plan actually gets implemented. AI engines also refresh on their own schedule, not yours, so even a perfectly executed fix will not show a citation improvement overnight.
Conclusion: The Cost of Finding Out Is Zero
For an enterprise leader weighing whether AI answer engines are already reshaping how buyers in Hong Kong find vendors, the AEO Auditor removes the only real objection: cost. A free, 30-second, no-card scan either confirms your business is visible or shows exactly where it isn't, before you commit any budget to fixing it.
We understand AI. We understand you. With UD by your side, AI never feels cold, and that starts with knowing, in real numbers, whether the AI your customers are already using can actually find you.
