The basics

What is an AI search visibility audit?

An AI search visibility audit maps the exact gaps in your brand's presence across AI engines - not just a score, but a matrix of which prompts and engines miss you, which competitors fill those gaps, and a prioritised list of fixes ranked by impact. CitedSpy queries ChatGPT, Perplexity, Gemini, Claude and Grok live and returns a structured audit report in minutes.

A score tells you where you stand; an audit tells you where you are broken and what to fix first. Traditional AI visibility scores compress all the signal into one number, which is useful for tracking but not for acting. An AI search visibility audit surfaces the underlying structure: a matrix of every prompt tested against every engine reached, showing exactly where your brand appears and where it is absent - the specific combinations a score cannot show.

That gap matrix is the starting point for diagnosis. It is common for a brand to appear reliably on Perplexity, which leans on live web search, while being absent on Claude or Gemini, which weight training data more heavily. A brand might win the 'best tool for X' prompt on three engines while going unmentioned on 'how to do Y' prompts that attract the same buyers. A score averages those patterns together; an audit exposes each gap individually so you know which one to close first.

The second layer is competitor overlap: who fills the space your brand leaves? When AI engines do not name you on a prompt, they name someone else - and that name is actionable information. Knowing that a specific rival consistently appears where you are absent is far more useful than knowing your overall mention rate is low. It tells you exactly whose authority in the engines' view you need to match, and what content they publish that you do not. This is what makes an audit different from a checker: it gives you a specific competitive brief, not a general score.

The third layer is a prioritised fix plan derived directly from the gap data. Rather than generic GEO advice, each fix is grounded in the specific audit finding it addresses - the worst engine, the most-blocking competitor, the prompts where you have partial coverage and are therefore closest to full closure. Generative Engine Optimization works when it is targeted; an audit is the targeting mechanism.

How to use it

Run your audit in four steps

1

Enter your brand and domain

Type your brand as buyers search for it and add your domain so we can ground the audit in your exact product and category. The domain is optional but recommended - it lets us tell when an engine cites your own site and makes niche or local brands work reliably.

2

We find your competitors and prompts

CitedSpy identifies the roughly five competitors AI engines most often recommend in your category and selects the real buyer prompts where you should appear near the top. These are the specific engine-prompt pairs that matter for your business.

Read your gap matrix

A table maps every prompt against every engine. Each cell shows your rank or marks you absent. Coloured by health - green where you appear, grey where you do not - the matrix makes every gap visible at a glance, not buried in an aggregate number.

Get your fix plan

The audit derives a ranked fix plan from the actual gaps. Priority one is always the highest-impact gap - the engine with the most absences, the competitor you need to counter, or the prompts where partial coverage means you are closest to closing the gap fully.

Reading the result

How to read your audit report

Start with the health label above the matrix. 'Good visibility' means gaps are minor and spread - no single engine or prompt is badly broken. 'Patchy visibility' means there are meaningful clusters of absence worth fixing. 'Critical gaps' means your brand is largely absent and the audit's fix plan is where to invest first. The label is derived from your gap rate: the share of possible appearances (prompts times engines reached) where you were absent.

Then scan the matrix row by row. A prompt where you are absent on all engines is a category-level coverage failure - engines simply do not associate your brand with that query at all. A prompt where you appear on two or three engines but miss one or two is a partial gap, the easiest to close since you already have some authority there. The gap count column on the right makes the worst rows visible immediately.

The competitor overlap section tells you who occupies your gaps. If the same rival appears across most of your gap cells, that is your benchmark: their authority in the content AI engines cite is what you are missing. The fix plan translates this directly - target the specific rival with comparison content, earn mentions in the same authoritative sources they appear in, and fill the gap at the engine level where they beat you most.

The fix plan is prioritised by expected impact. Priority one is usually the highest-volume gap: earning third-party mentions if you are broadly absent, or targeting the engine with the most missing cells if your gap is concentrated. Working down the list in order is more efficient than spreading effort across all recommendations at once. Once a fix closes a gap, re-run the audit to confirm and find the next priority.

Key takeaways

What to remember

  • An AI search visibility audit shows which specific prompt-and-engine combinations your brand is missing from - the gap structure that a score cannot surface.
  • Gaps cluster by engine and by prompt type, so a single aggregate score conceals where the real problem is.
  • Competitor overlap tells you who fills your gaps and what content authority you need to match them.
  • Partial gaps - prompts where you appear on some engines but not others - are the fastest wins because you already have some authority there.
  • A prioritised fix plan derived from the actual gap data is more actionable than generic GEO advice.

How it works

Our methodology

The audit runs in two phases. First, CitedSpy works out who you are: when you provide a domain we fetch and read your homepage directly, then use that plus live web search to identify your category, the roughly five competitors engines tend to recommend in your space, and a set of natural buyer questions where you should rank near the top. This research phase is what makes the audit meaningful for niche and local brands the models may not have encountered directly.

Second, every prompt is sent to each available engine - ChatGPT, Perplexity, Gemini, Claude and Grok - using their live web-search tools where supported. We read each answer for whether your brand is named and in what position, producing a matrix of prompt by engine with your rank or an absence marker in each cell. From that matrix we derive the gap count, gap rate, competitor overlap, and the ordered fix plan. Only engines actually reached are included - a slow engine is recorded as not reached so it cannot inflate your apparent gap count.

The fix plan uses a set of heuristics applied to the gap data: the engine with the most absences drives the engine-specific fix; the competitor with the most overlap drives the counter-content fix; partial gaps (present on some engines, absent on others) are flagged as fast wins; low own-domain citation rates flag a citation-authority problem. Each fix is tied to a specific finding, not a generic recommendation. This is the same data CitedSpy uses in its paid tracking product to flag regressions and prioritise weekly optimisation tasks - the audit makes one pass of that logic free.

FAQ

AI Search Visibility Audit, answered

Yes. A full audit is free and needs no signup - enter a brand and optional domain, we find your competitors and prompts, query five engines live, and show you the complete gap matrix, competitor overlap, and fix plan. A free CitedSpy trial adds weekly re-runs so you can track whether the fixes are closing the gaps.
A score compresses all the signal into one number - useful for tracking trend over time. An audit surfaces the underlying structure: a matrix of which prompts and engines miss your brand, who fills those gaps, and a ranked list of specific fixes. Use the score for tracking; use the audit for diagnosis and action.
A visibility gap is a specific prompt-engine combination where your brand is absent from the AI answer. If ChatGPT does not name you when someone asks 'best SEO tools for agencies', that is one gap. The audit finds every such combination across all prompts and all engines reached, making it possible to prioritise the worst gaps rather than guessing where the problem is.
The fix plan is derived from the actual gap data, not generic advice. It identifies the engine with the most absences, the competitor who most often fills your gaps, prompts where you have partial coverage (easiest to close), and whether your own domain is rarely cited (a sign that your content lacks citation authority). Each fix targets a specific finding from the audit.
At least monthly, because AI answers drift as models retrain and competitors publish. The gap matrix from one month is your baseline; the next month's shows whether gaps closed or new ones opened. Running the audit after a content push - a new comparison page, a G2 review campaign, a PR mention - is the most direct way to verify whether the effort moved your presence.
ChatGPT, Perplexity, Gemini, Claude and Grok, queried live with web search where the engine supports it. Copilot is on the roadmap. The matrix only shows engines we actually reached - a slow or rate-limited engine is recorded as not reached rather than shown as a false gap.
