Can You Actually Check Whether AI Recommends Your Content?
Yes. An AEO audit scans your site the way AI engines read it, then scores whether ChatGPT, Gemini, Perplexity, Claude and Google AI Overviews can find, parse and cite your pages. Free scanning tools now exist, including UDomain's AEO Auditor, which runs a full scan in about 30 seconds with no sign-up.
Most people who publish content still do not know this kind of check exists. They see traffic flattening, suspect AI answers are absorbing their clicks, and stop there, because "how AI sees my site" feels unmeasurable. It is measurable, and the first measurement costs nothing.
AEO (Answer Engine Optimization) is the practice of structuring your content so AI engines can quote it as the answer. Where SEO earns you a ranking and a click, AEO earns you a citation inside the AI's response itself.
What Does a Free AEO Scan Actually Check?
A free scan audits the machine-readable layer of your site: schema markup, AI crawler access, content structure, answerability and internal linking. It returns a score, a pass/fail breakdown and a prioritised fix list. It is a one-time snapshot, not continuous monitoring.
Here is exactly what the free UDomain AEO Auditor scan includes, so you know what you are getting before you paste in a URL:
--- Cost: 100% free, no credit card, no account required.
--- Speed: results in under 30 seconds for most sites; complex sites may take up to 60 seconds.
--- Engines covered: ChatGPT, Google AI Overview, Perplexity, Claude and Gemini.
--- Checks run: 170+ AEO structure checks across your site.
--- Report modules: an overall AI visibility score, AI copy signals, numeric structure checks, and a prioritised action plan.
--- Email: only used to show the full dashboard; no charges or auto-billing.
These facts come from the tool's own published documentation, so you can verify each one on the product page before running anything.
How Do You Run Your First AEO Audit?
Running a first audit takes three steps: paste your URL into the scanner, wait for the dashboard to build, then read the action plan from the top down. The highest-priority items are almost always structural: missing schema, blocked AI crawlers, or headings that do not match the questions people ask.
A practical workflow for your first pass:
--- Step 1: scan your homepage first, then your three most valuable content pages. Scores often differ sharply between them.
--- Step 2: note the failed checks. Do not try to fix all of them; group them into structural fixes (schema, crawler access, heading hierarchy) and content fixes (answerability, citations, internal links).
--- Step 3: fix structural items first. They are usually one-time changes, and AI engines typically re-crawl structural changes within 2 to 4 weeks.
--- Step 4: re-scan monthly to see whether your score moves.
If you have already read our llms.txt explainer, an audit is where that theory becomes a checklist for your own domain.
What Do the Results Mean, and What Should You Fix First?
Your score reflects how readable and quotable your site is to AI engines today. Fix order matters because signals accumulate at different speeds: structural changes are typically re-crawled within 2 to 4 weeks, while citation and authority signals take 1 to 3 months to build.
That two-speed timeline explains a common frustration: teams fix everything at once, see nothing change in a fortnight, and conclude AEO does not work. The structural half of your fixes shows up first; the authority half compounds quietly over the following quarter.
Read your report with that split in mind. A failing schema check is this week's work. A weak citation profile is this quarter's content plan. Mixing the two horizons is how AEO projects lose momentum.
What Will a Free Scan Not Do?
A free scan will not monitor your AI visibility continuously, track competitors over time, or tell you which specific buyer prompts mention your brand week by week. Those jobs belong to paid tracking tools, and an honest audit workflow usually combines both.
Three limitations to be clear about before you start:
--- It is a snapshot. Continuous AI-visibility trackers such as Otterly.AI start at around US$29 per month for prompt-based monitoring. A free scan tells you where you stand; a tracker tells you whether you are improving.
--- It measures your site, not the whole answer. AI engines also weigh third-party mentions such as reviews, Reddit threads and Wikipedia, which no site scan fully controls.
--- A perfect score is not a guarantee. AEO raises the probability of being cited; it cannot force any engine to pick you.
If you are deciding where AEO sits against your existing search budget, our AEO vs SEO spending guide covers that trade-off in detail.
Who Should Run an AEO Audit Now?
Anyone whose business depends on being found: marketers watching organic traffic flatten, content teams publishing weekly, and founders whose competitors already appear in AI answers. If a customer asking ChatGPT about your category today would not hear your name, you are the exact person the free scan was built for.
The practical trigger is simple. Open any AI assistant and ask it the question your best customer would ask. If your brand does not appear, you have a visibility gap you can now measure, and the measurement is free, takes half a minute and requires no commitment.
Conclusion: Measure First, Then Optimise
The rules of search have changed, but the first move has not: measure before you optimise. A free AEO audit turns "AI probably ignores my site" into a scored, itemised, verifiable to-do list, and it costs you thirty seconds.
