What tools should marketing agencies use to track AI search visibility for clients?
A marketing agency running GEO for clients needs three categories of tooling: an AI-visibility platform that scans ChatGPT, Perplexity, Gemini, Claude, and DeepSeek on a schedule, a citation auditor that tells you who AI engines cite for your client's target prompts, and a content auditor that flags structural fixes on the client's pages. Most agencies overbuy by stacking three competing platforms in the first category. Pick one, learn it well, layer on the other two categories as you grow.
Category one: AI-visibility platforms
This is the core tooling. You give it a list of tracked prompts and competitors, it scans the major AI engines on a schedule and reports visibility, rank, sentiment, and citation share over time. AI-visibility platforms in this category include avisibli, Profound, Peec, and Otterly, among others.
What to evaluate when picking one:
- Engines covered. All five (ChatGPT, Perplexity, Gemini, Claude, DeepSeek) is the current bar. Some platforms cover only two or three.
- Workspaces and seats. Agencies need either multi-workspace pricing or a way to run client work without exposing each client's data to the others.
- Reporting fit. Can you export or white-label a client-friendly report, or do you have to rebuild it in Notion every month?
- Pricing model. Per-prompt, per-workspace, or per-seat. Each one rewards different agency shapes.
Do not stack two AI-visibility platforms. They scan overlapping engines and answer the same questions; the marginal data from a second platform rarely justifies the second invoice.
Category two: citation auditors
Once you know your client appears in 14 of 40 prompts, the next question is which sources the engines cite. Some AI-visibility platforms include citation auditing; some require a separate tool. The capabilities you want:
- List of all unique sources the engines cited across your client's tracked prompts
- Breakdown by domain authority and content type (review site, forum, news, client's own domain)
- Gap analysis: where competitors are cited that the client is not
For a digital agency with 60 SMB clients, citation auditing is what turns visibility data into a content roadmap. "Perplexity cited G2, Reddit, and three competitor blogs but not your domain" tells you exactly where the content effort needs to go.
Category three: content auditors for GEO
The third category checks the client's own pages for structural problems that hurt AI citation: missing or invalid schema, thin pages, missing FAQ sections, unclear answers to common prompts. This is closer to traditional SEO tooling but tuned for what AI engines actually parse. Ahrefs and Screaming Frog can cover parts of this; some AI-visibility platforms include a GEO-specific audit.
What you do not need (yet)
Resist buying:
- Standalone AI-content-generation tools. The client's existing content workflow plus a competent writer beats most of them.
- Sentiment-only platforms. Sentiment matters but is a sub-feature of the AI-visibility platform, not a category of its own.
- "AI SEO" platforms that promise to optimise for "AI search algorithms" without naming engines. If the marketing page does not list ChatGPT, Perplexity, Gemini, Claude, DeepSeek by name, treat it skeptically.
Build vs buy vs partner
A 30-person B2B SaaS agency that already has analyst capacity can buy a single AI-visibility platform and a content auditor, and deliver GEO services in-house. A smaller shop, or one without GEO expertise on staff, will be slower to ramp up; partnering with a GEO specialist for the first few client engagements is often faster than learning the category from scratch while billing for it.
