AI Visibility Audits for Marketing Agencies

A marketing agency can offer AI-visibility audits by running TAMGIO's one-time Audit Mode against a client's domain and handing over a branded PDF report as the deliverable. The scan covers roughly 20-30 auto-generated prompts across OpenAI, Perplexity, Gemini and Google AI Overviews in a single pass, finished in a day rather than a week of manual research. Every metric in that report links back to the raw API response behind it, which is what makes the audit defensible enough to sell and easy to upgrade into an ongoing tracking retainer.

Why agencies are adding this to their service list

Clients already ask agencies "does ChatGPT recommend us" or "why does our competitor show up in AI Overviews and we don't" — a question standard SEO reporting doesn't answer. Rank trackers and keyword tools don't touch generative answers at all, and manually pasting prompts into ChatGPT produces a screenshot, not evidence: AI answers change between runs, so a single check proves nothing about actual visibility. An audit product built on repeatable, N-sample measurement fills that gap and gives the agency something new to bill for without building an in-house research team.

The audit-to-retainer model, step by step

  1. Scope and sell the audit as a fixed, one-time deliverable — a domain gets scanned once, not tracked continuously.
  2. Run Audit Mode: point it at the client's domain, approve or edit the auto-generated prompt set (spread across best-of, comparison, how-to, local and pricing intents), and start the scan. One scan covers all four engines.
  3. Hand over the branded PDF. It carries the same Mention Rate, Share of Voice, Citation Rate and Prompt Coverage numbers the agency would see in the dashboard, laid out for a client who has never heard of GEO.
  4. Use the findings — the prompts where the brand is invisible, the competitors dominating Share of Voice — as the pitch for an ongoing tracking project.

What the report actually contains

  • Four measured surfaces: OpenAI web_search, Perplexity Sonar (always grounded), Gemini grounded search, and Google AI Overviews via SerpAPI. AIO is SERP-embedded and deterministic per search — when it doesn't appear, that's recorded as "no_surface," not counted as a mention miss, so the report never misrepresents absence.
  • Core metrics — Mention Rate, Share of Voice, Citation Rate, Prompt Coverage — are all N-sample proxy measures, never a single-shot answer, because AI output is non-deterministic.
  • Every metric carries the raw evidence behind it: the API response, citations, and timestamp are one click away, so a skeptical client (or their in-house technical lead) can verify the number instead of taking the agency's word for it.

Positioning the audit without overselling it

Resist the temptation to promise a percentage lift. No honest tool can tell a client "you'll go from 60% visibility to 90%," because AI answers are non-deterministic and no vendor controls what the model says next. What sells instead is specificity: which of the 20-30 prompts the client's brand never showed up in, which competitor is winning Share of Voice on comparison and best-of prompts, and where a citation exists but the mention itself is weak. Every formula behind those numbers is public, so agencies can walk a client's team through exactly how a score was built — the opposite of a black-box score with no audit trail.

From one-time audit to recurring revenue

The audit is the door-opener; the retainer is where the recurring line item lives. TAMGIO's planned pricing has three tiers for ongoing tracking projects — Weekly Scan, Daily + Competitors, and an Agency/White-label tier aimed specifically at agencies running multiple client projects under their own brand. None of the tiers have published pricing yet, but the shape of the offer is already clear: audit first, then convert the client that has a visibility gap into a tracked project that watches whether the gap closes.

FAQ

How long does an AI-visibility audit take to run?
Audit Mode scans roughly 20-30 auto-generated prompts across OpenAI, Perplexity, Gemini and Google AI Overviews in a single pass, and typically finishes within a day. The prompts are auto-generated but reviewed before the scan starts, so no manual research phase eats into billable time.
Can we put our agency's branding on the audit report?
Yes — the audit exports as a PDF report. The Agency/White-label tier is one of three planned pricing tiers built specifically for agencies delivering audits and tracking to multiple clients under their own brand; exact packaging details are still being finalized.
What happens after the one-time audit — how do we sell the retainer?
The audit becomes the pitch. It exposes the specific prompts and competitors where a client is invisible, which is the natural lead-in to an ongoing weekly or daily tracking project that keeps measuring after the one-off snapshot.
How is this different from asking ChatGPT a few times manually?
A manual check is a single unverified sample. AI answers are non-deterministic, so one screenshot proves nothing about a client's actual visibility. TAMGIO runs N-sample measurement across dozens of prompts and four engines, with the raw evidence behind every number one click away.
Can we promise clients a specific visibility percentage increase?
No honest tool can promise that — AI answers are non-deterministic, so a claim like 'go from 60% to 90%' isn't something TAMGIO will help you make. The audit instead gives you defensible baseline numbers and evidence to track real change over time.
