An AI visibility audit measures how often AI search engines cite a brand’s site and name the brand in their answers. SERP Masters is an SEO agency that runs this audit for businesses. The free run sends 12 editable prompts to eight AI surfaces. It scores four separate panels: citation presence, mention presence, retrieval access, and extractability plus entity. The result is a per-engine baseline of where AI answers send buyers, shown on screen before any email is requested.

Citation figures are de-duplicated across Ahrefs, DataForSEO and live renders. Ranking and citation outcomes cannot be projected with certainty.
Buyers ask AI engines for shortlists. ChatGPT, Perplexity, Gemini, Claude, Copilot and Google AI Overviews answer with a few names and links. A rank tracker cannot tell you whether those answers cite your site and name your brand.
The SERP Masters audit shows you the results engine by engine, and its prompt-by-prompt table traces every number to an answer you can read.
The measurement is a citation-presence rate on a fixed prompt panel, scored per engine and never blended. SERP Masters uses the same measurement on client work, where AI citations grew 80% year over year.
The audit is the Diagnose step of the AI SEO services engagement at SERP Masters, so nothing gets fixed before it is measured. You need a domain, a brand name and a location to start.
What does the SERP Masters AI visibility audit measure?
The SERP Masters AI visibility audit measures four things, each reported as its own panel.
Citation presence
Citation presence counts only answers with readable sources. An AI Overview with no readable source list is recorded and left out of the denominator, so a hidden list never counts against you.
Mention presence
Mention presence matters because a named brand makes the buyer’s shortlist even without a link. A brand named more often than it is linked is known to the engine, which has no page of yours it wants to cite.
Retrieval access
Retrieval access is tested by requesting your site as 16 AI user agents, among them OAI-SearchBot, ChatGPT-User, PerplexityBot, ClaudeBot, Googlebot and Bingbot. Only the 11 that fetch pages to answer a live question count. Training-only crawlers such as GPTBot and CCBot appear in the access matrix and stay out of the score, since blocking them does not stop a live answer from citing you.
Extractability and entity
Extractability and entity checks test whether an engine can quote a usable passage and tie it to the right organization. Page checks compare raw HTML with the rendered page, confirm structured data survives rendering, and look for an answer capsule near the top. Entity checks look for an Organization node with a stable @id, sameAs links and consistent contact details.
Why citations and mentions are never blended
Citations and mentions call for different fixes. A brand cited on 40% of prompts and named on 10% has a different problem from one named on 40% and cited on 10%; an average makes them identical. Engines are kept apart for the same reason: a brand can hold steady in Perplexity and sit at zero in Gemini.
Which eight AI surfaces does the audit check?
The audit checks eight AI surfaces: five answered live during your run, and three read from the Ahrefs AI citation index, kept in their own column.
The guide to earning AI Overview citations covers what AI Overviews draw from.
The 12 prompts: shown and editable before the run
All 12 prompts are on screen before the run, and you can rewrite any of them to match what your buyers ask.
Brand prompts alone flatter a brand: a business named on every brand prompt can be missing from every commercial prompt, where the shortlist forms. Each prompt is also classed local or national.
What does the AI visibility report show?
The AI visibility report shows the four panels, a Judged grade, and the answer behind every number.
The report shares by link. Email is requested only for a PDF copy or a full-audit request, pre-filled with your run ID.
How does the free audit work?
The free run takes six steps and about a minute.
One limit: the free run sends each prompt once, and AI answers vary between runs, so the result is a snapshot.
In what order should you fix AI visibility problems?
Fix AI visibility problems in dependency order: access, then the page, then the gaps in the answers. A lower fix does little while one above it is open.
How does a measured audit differ from a modeled AI visibility score?
A measured audit reads real AI answers. A modeled AI visibility score estimates visibility from homepage signals, as many of the tools SERP Masters reviewed do.
This audit is a point-in-time measurement. Ongoing monitoring is a separate job, covered in the comparison of AI visibility tools and trackers.
Free AI visibility checker or full audit?
The free AI visibility checker gives a 12-prompt baseline. The full audit covers a whole topic cluster, runs every prompt three times, and is quoted from your free run.
The full audit is priced by scope: the number of topic clusters, competitors benchmarked and locations the prompts run in. It also depends on you, since the per-bot matrix needs access to your CDN settings.
Who is the AI visibility audit for?
The audit is for businesses whose buyers ask AI engines for recommendations before they call or book.
The audit also works as an LLM visibility checker. Its live surfaces run with web search on, so it measures what an engine retrieves today; the guide to how LLMs represent brands covers what a model repeats from training data.
What results has this method produced?
The method this audit starts has produced measured AI citation growth across the SERP Masters client portfolio.
More client results are on the SERP Masters case studies page.
“After a year of paying an agency that quietly did nothing, working with SERP Masters was like someone flipping the lights on. Andy audited the damage, gave me the honest version of how bad it was, and got us moving again.”
What happens after the audit?
The audit is the Diagnose step of the SERP Masters method: Diagnose, Architect, Execute, Corroborate, Measure. The fix list feeds Architect and Execute, where each prompt class gets an owning page. Direct-answer pages follow direct-answer AEO work; pages in multi-source answers follow GEO work for synthesized answers. The cited-domain league sets Corroborate targets, and Measure re-runs the same prompts on the same surfaces.
Report terms such as grounding and query fan-out are defined in the glossary of AI search terms.

“What I value most is that Andy tells me the truth even when it’s not what I want to hear. Across the entire engagement I never once felt managed or spun. That’s rare in this business, rarer than it should be.”
Answered the way an engine would extract it.
Each answer opens with the answer. The FAQPage schema is generated from these fields and nothing else.
01What is an AI visibility audit?
An AI visibility audit is a measured check of whether AI search engines cite a brand’s site, name the brand, can fetch its pages, and can quote a usable passage. The SERP Masters version runs 12 editable prompts across eight AI surfaces and reports those four results as separate panels, each traced to the answers behind it.
02How do you measure AI visibility?
You measure AI visibility by sending a fixed set of buyer prompts to each AI surface and recording whether each answer cites the brand and whether it names it. SERP Masters reports both as per-surface rates, adds a bot access test and page checks, and keeps the prompt set fixed so later runs compare like for like.
03What does AI visibility mean?
AI visibility means how often a brand appears in answers from AI engines such as ChatGPT, Perplexity, Gemini, Claude and Google AI Overviews. It covers two outcomes: being cited as a linked source and being named in the answer text. SERP Masters measures them separately because a brand that is named but never cited needs a different fix.
04Can ChatGPT do an SEO audit?
ChatGPT can review a pasted page and suggest changes, and it can answer the prompts an audit tests. It cannot request your site as 16 AI user agents, compare raw and rendered HTML, or score its answers against other engines. The SERP Masters audit treats ChatGPT as one of eight surfaces it measures.
05Is the AI visibility checker free?
Yes, the SERP Masters AI visibility checker is free for one run of 12 prompts across eight surfaces, and results appear on the page without an email address. One-time audits and project work are quoted after the free audit.
06How is the AI visibility score calculated?
The SERP Masters AI visibility score is an A to E grade labeled Judged, set from four measured panels: citation presence, mention presence, retrieval access, and extractability plus entity. The weights stay internal. The four panels always sit beside the grade, so you never have to take the grade on trust.
07Why do AI visibility results change between runs?
AI engines can return different answers to the same prompt minutes apart, and Google AI Overviews also change by location. The free run is a single snapshot and says so in its method note. The full audit sends each prompt three times and reports a band, which separates a real gap from ordinary answer variation.
