By the end of this page, you will know exactly what the free UDomain AEO Auditor scan gives you, what it costs (nothing), what it asks of you (a domain, and an email if you want the full dashboard), and where it stops being enough. You will also know whether to run it yourself this week or hand it to your digital team.
Quick answer: it is a free, no-card, no-sign-up AI visibility audit built and run in Hong Kong. Most sites get a report in under 30 seconds.
What is a free AEO audit?
A free AEO audit is an automated check of how readable, quotable and visible your website is to AI answer engines such as ChatGPT, Gemini, Perplexity, Claude and Google AI Overviews. Answer Engine Optimisation (AEO) differs from SEO: it aims to have your content cited inside the AI answer, not just ranked as a blue link.
The business case is now well documented. In February 2024, Gartner predicted that traditional search engine volume would drop 25% by 2026 as users move to AI chatbots and virtual agents. In 2025, an Ahrefs study found that Google AI Overviews were associated with a 34.5% lower click-through rate for the top-ranking page.
For a Hong Kong B2B firm, that means a buyer may shortlist vendors inside an AI conversation before ever visiting a website. An AEO audit tells you whether you are even in that conversation.
What does the UD AEO Auditor free scan include?
The free scan produces a report with four modules: an overall AI visibility score, AI copy signals, numeric structure checks and a prioritised action plan. According to UD's product page, it runs more than 170 AEO structure checks, covering schema markup, AI crawler access, answerability, peer comparison and internal linking.
Trial facts at a glance

--- What happens after: nothing is billed. You can rescan monthly, or request a paid implementation consultation.
Do I need a credit card or contract to start?
No. The scan requires no credit card, no account and no contract. You enter a URL and the report generates on the page. An email address is requested only if you want the full interactive dashboard and follow-up analysis, and UD states that providing it does not trigger any charge.
That matters for enterprise buyers in particular. Many paid AI visibility platforms need a procurement cycle, vendor onboarding and a data-processing review before the first report.
A free public-site scan avoids all of that because it reads only what is already public on your website. No internal systems are connected, and no personal data leaves your organisation.
How long does it take to see results after fixing issues?
The scan itself takes under a minute. Improvements show up more slowly, because AI engines refresh on their own schedules. UD's FAQ states that structural fixes are typically re-crawled within 2 to 4 weeks, while citation and authority signals take 1 to 3 months to build. UD recommends rescanning monthly.
For planning purposes, a realistic timeline for an enterprise site looks like this:
--- Week 0: baseline scan and score shared with marketing and IT.
--- Weeks 1 to 2: high-priority structural fixes, such as JSON-LD schema, H1 consistency and crawler access in robots.txt.
--- Weeks 3 to 6: rescan to confirm structural changes have been picked up.
--- Months 2 to 3: content and citation work, such as answer-first copy, named sources and third-party mentions, begins to influence AI citations.
What does each part of the AEO report tell you?
Each module answers a different management question. The score tells you where you stand, copy signals show whether your writing is quotable, the structure checks explain why AI may fail to read your pages, and the action plan tells your team what to fix first, ranked by expected impact on the score.
--- Overall score: a single number with an industry comparison. This is the figure leadership will remember, so record it before anyone changes the site.
--- AI copy signals: whether your pages use citations, named sources and a direct, conversational answer style. Corporate pages written as brochures often score poorly here.
--- Structure checks: technical items such as JSON-LD coverage, heading consistency, internal linking and whether AI crawlers are allowed in robots.txt.
--- Action plan: prioritised fixes labelled by urgency, which convert directly into tickets for your web team or CMS vendor.
A common pattern in Hong Kong enterprise sites is a strong technical base with weak copy signals. Service pages describe capabilities in general terms but rarely state facts an AI can lift, such as response times, coverage areas, certifications or pricing ranges.
What should you ask before paying for AEO work?
Before paying any agency or platform, ask for a baseline, a measurement method and a timeline. A credible provider will show your current score, explain how they will track AI citations over time, and set expectations that structural fixes take weeks while citation gains take months. Avoid anyone promising guaranteed AI placement.
Five questions worth putting to any AEO vendor, including UD:
--- 1. What is our baseline today, and which tool produced it?
--- 2. Which AI engines and which buyer prompts will you track, and how often?
--- 3. Which fixes will our team do, and which will you do?
--- 4. What result should we expect at 30, 60 and 90 days?
--- 5. What happens to our content and data if we stop the engagement?
Running the free scan first gives you an independent number to hold any vendor's claims against, which strengthens your position in the procurement conversation.
Who should run the free audit, and who needs more?
The free scan suits any Hong Kong organisation that has never measured its AI visibility and wants a baseline before committing budget. Teams that need daily share-of-voice tracking across hundreds of prompts and markets will need a dedicated monitoring platform or a managed engagement on top of the free scan.
Verdict by buyer type
--- Head of Digital or Marketing, no AEO baseline yet: start with the free scan. It is the fastest way to put a number in front of leadership.
--- IT Director asked to "fix AI visibility": use the structure checks and action plan as a technical backlog for schema, crawler access and internal linking.
--- COO building a business case: use the score and peer comparison as the "current state" slide, then rescan after 4 weeks to show movement.
--- Global brand with a dedicated AEO team: the free scan is a useful second opinion, but platforms such as Profound or Semrush's AI visibility tools offer deeper continuous tracking.

What are the limitations of a free AEO audit?
A free scan is a point-in-time diagnosis of your public website, not an ongoing programme. It cannot rewrite content, build third-party citations or guarantee AI engines will recommend you. Implementation consultation is a separate, quote-based service, and UD does not publish a fixed price for it.
Being honest about those limits helps you set expectations internally:
--- Snapshot, not monitoring: one scan shows today's state. Trend tracking depends on you rescanning.
--- Public pages only: gated content, portals and PDFs behind login are outside its scope.
--- Diagnosis, not delivery: fixes still need your web team, your CMS vendor or an agency.
--- No guaranteed outcome: AI engines decide what to cite. A better score improves your odds, but it does not buy placement.
--- Email for full detail: the complete dashboard requires an email address, which some teams will route through a shared inbox.
How do I run the scan and use the report internally?
Run the scan on your main corporate domain first, then on one key product or service subdomain. Export or screenshot the score, the failed checks and the top three actions. Share them with marketing and IT in one short meeting, assign an owner to each high-priority fix, and book a rescan four weeks later.
A practical five-step routine:
--- 1. Go to the AEO Auditor and enter your domain.
--- 2. Note your overall score and how it compares with your industry.
--- 3. Pull the high-priority items from the action plan into your web team's backlog.
--- 4. Ask one question your buyers would ask an AI assistant, such as "best IT managed service provider in Hong Kong for a 200-person firm", and record which brands are named.
--- 5. Rescan after 4 weeks and report the change upward.
Conclusion: measure first, then decide what to buy
The right next step is not a six-figure AEO retainer. It is a baseline. A free, 30-second scan with no card and no contract gives you the number you need before anyone asks for budget. If the gaps are large, that is when a consultation is worth the conversation.
We understand AI. We understand you. With UD by your side, AI never feels cold.
Run your free scan, then let us help you act on it. We'll walk you through every step, from reading your score and prioritising fixes to schema, content and citation work that makes AI engines quote you.
