Key takeaways
- Gauge lists a Growth plan at $599/mo and describes itself as an end-to-end AI marketing agent. Agencies often need something different: cheaper per-client math, white-label reports and client logins.
- We found no independent review of Gauge and no confirmation that it offers true white-label, custom domains or client portals. Test those in a trial before you commit.
- Promptwatch is the strongest option if you want agents that fix visibility problems, not just report on them. Rank Prompt, ZeroRank, SE Ranking and Search Party are the closer matches for lean, white-label-first agency workflows.
- Nearly every vendor ranking in this space is a vendor ranking itself first. Treat all rankings, including the ones in this guide, as claims to verify.
- Report per engine, not as one blended score. ChatGPT cites about 5 sources per answer and Google AI Overviews about 10, so the numbers mean different things.
Why agencies look beyond Gauge
Gauge (withgauge.com) is a prompt-level GEO tool. Its own page lists prompt tracking with citation-rate and mention-rate reporting by client and topic, an "Ask Gauge" workflow layer, a content engine that draws on GA4, GSC, DataForSEO and ad data, and an "Agency Mode" for pitch work. Pricing is Growth at $599/mo, then custom Enterprise.
That is a decent feature set. The problem for agencies is usually economics and delivery, not features. Gauge's own page admits the tool is broader than monitoring-only products and needs workflow adoption to pay off. A competitor, Rank Prompt, calls it "newer and leaner" with limited agency workflow tooling, and tells readers to test export and branding before using it for client work. That is a competitor's opinion, and it sits oddly next to a $599 price point, so I would not lean on it. But it points at the right question: can you hand a client a branded report without them touching a vendor login?
In plain terms, agencies tend to leave a tool like this for one of four reasons:
- Cost per brand climbs too fast once you pass 10 or 20 clients.
- White-label stops at a logo swap, with no custom domain or email sender.
- There is no client portal, so you are exporting PDFs by hand.
- The tool tells you where you are invisible but does nothing about it.
What to score on before you pick
The research across vendor pages is consistent on the criteria. Score every candidate on these:
- White-label reports, including logo, colors and no vendor name in the footer
- Client portals with a custom domain and email sender
- Multi-brand management and per-brand pricing
- Prospecting or pitch audits for new business
- API access
- Per-client prompt libraries
- Exportable reports that need no client login
Two pitfalls come up again and again. First, every vendor claims "agency support," but the depth ranges from filtered views to a true multi-client operating layer. Second, tracking the same 200 prompts for every client wastes budget. Build prompt sets per client, and keep them short and keyword-like. Promptwatch Data's ChatGPT query fanout report shows average fanout query length falling from about 117 characters in early December to about 53 from April, so phrasing that matched last quarter's queries may already be stale.
Report per engine, not one blended score
Promptwatch's average sources per response data (tracked daily, report dated September 2025) found ChatGPT cites about 5 sources per web-search answer, Google AI Overviews about 10, and Perplexity almost exactly 10 every day. Microsoft Copilot swung from under 2 to nearly 17 within weeks before settling low. A blended visibility number hides all of that. Pick a tool that lets you show each client a per-engine view, and judge Copilot on monthly trends instead of weekly snapshots.

The alternatives
Promptwatch
Promptwatch is where I would start if your agency sells results, not dashboards. Most tools in this category answer "was my client mentioned?" Promptwatch tries to answer "how do we grow AI-driven revenue for this client?" It tracks the real interfaces of ChatGPT, Google AI Overviews, AI Mode, Gemini, Perplexity, Copilot and others, and then connects that to crawler logs, visitor analytics and content work.
For agencies specifically, the plans are the draw. Kick-off ($199/mo), Growth ($399/mo) and Scale ($799/mo) include unlimited projects, pitch projects and prompts, 10 seats, all models, Agent Chat, country, state and city tracking, crawler logs, visitor analytics, site audits and custom reports. Exports and schedules can be white-labeled, and clients can get branded read-only access. Compare that with a flat $599 for one tool tier, and the per-client math looks very different once you pass a handful of accounts.
What separates it from monitoring-only tools is the action side. IP-verified AI crawler logs show whether bots can read a client's site. Content gap analysis and the Action Board turn findings into a prioritized to-do list. One honest caveat: agency plans do not include the Content Agent, AEO articles, the Knowledge Base or 360 Insights. Those sit on Business and Enterprise. If you want automated publishing for a client, plan for a Business seat on that account.
Proven results help the pitch too. Crisp reported 2x higher conversion rates from AI traffic than from traditional channels, and TreeHouse (Pararius) grew AI search to about 25% of organic conversions. Confirm current pricing at promptwatch.com/pricing.
Rank Prompt
Rank Prompt
Rank Prompt is the most agency-priced option in the research. The Agency plan is $149/mo with white-label reports emailed after each scheduled run and 50 brands. Agency Plus is $299/mo, adding an agency dashboard, client logins on your own domain, prospecting tools and 500 brands. It tracks ChatGPT, Gemini, Perplexity, Grok, Claude, Muse and Google AI Overviews, and offers a free first report.
The catch: this is Rank Prompt's own description, and the same article ranks Rank Prompt well. Run the free report and look at the branding before buying.
ZeroRank
ZeroRank puts white-label dashboards on its Growth, Agency and Enterprise plans. Its pitch is separate client workspaces, controlled access and unlimited seats. That matters if your clients are in regulated industries or just touchy about seeing each other's data. Verify pricing directly.
SE Ranking Visible
Gauge's own list names SE Ranking as a white-label option. If your agency already uses SE Ranking for classic rank tracking and reporting, adding AI visibility there keeps one login and one set of branded reports. You give up some depth versus dedicated GEO tools.
Search Party
Search Party is positioned as an agency-focused AI search visibility platform. I could not verify pricing or white-label depth from the research, so treat it as a trial candidate.
AthenaHQ
Gauge's page ranks Athena second, describing a pitch workspace, executive dashboards with ROI tracking, 8+ LLMs and an action center. Useful if ROI storytelling to clients is your bottleneck. Pricing was not verified.
Profound, Peec AI, Otterly.AI and Scrunch
Profound is enterprise-oriented with custom pricing that Rank Prompt describes as typically four figures a month. The per-brand math gets ugly with 30+ small clients.
Peec AI has strong competitor benchmarking, but white-label and portal features are thinner.
Otterly.AI is lightweight and affordable, suited to small client books but shallow on white-label.
Scrunch AI leans toward a brand's own team. Check white-label and multi-brand pricing in a trial.
Semrush and Ahrefs add-ons
Both are worth a look if the agency already pays for the base suite. They are SEO suites adding AI tracking, so expect fixed prompt sets and less AI-specific depth.
Do you also need a general reporting tool?
Maybe. Most GEO platforms report on AI visibility only. If you also send clients paid media and analytics reports, a general agency reporting platform sits beside the GEO tool. The vendor comparisons in the research point at the usual suspects: AgencyAnalytics (full white-label with custom domain, but costs climb as clients grow and the Agency plan is the minimum for full branding), Whatagraph (80+ sources, full white-label on higher tiers), DashThis (white-label from the Professional plan, from $164/mo), Swydo (white-label on every plan, from $69/mo) and TapClicks for 50+ client enterprises. Looker Studio is free but has no native white-label or multi-client management, so skip it for external client reporting.
Treat those as separate purchases. They pair with a GEO tool instead of replacing it. For more GEO options, the directory at bestgeosoftware.com lists a lot more than fit here.
How to run a fair trial
Every source here is a vendor ranking itself first, so do not pick from a listicle. Pick three tools and run the same test:
- Load two real clients with different prompt sets, 20 to 30 prompts each, written as short keyword-style queries.
- Generate a client-facing report. Check for vendor names in the footer, email sender and URL.
- Try the client login. Can it live on your domain? Can a client see another client's data?
- Price it at your current client count and at double that.
- Ask what happens after the report. Does the tool tell you what to fix, and can it help fix it?
Step 5 is where tools split. A tracker tells you that a client is missing from ChatGPT answers. A platform with crawler logs and content gap analysis tells you why. Promptwatch Data's ChatGPT citation share by content type report (Sep 28 to Oct 4, 2026) has product pages at 22.4% of citations, so what you publish matters as much as what you track.
Which one for which agency
- 5 to 20 clients, tight margins: Rank Prompt Agency or Agency Plus, or Promptwatch Kick-off if you want the optimization side.
- 20 to 50 clients, serious delivery: Promptwatch Growth or Scale, or ZeroRank.
- Already inside SE Ranking: try SE Ranking Visible first.
- Mostly pitching new business: test Gauge's Agency Mode and Athena's pitch workspace against Promptwatch's pitch projects.
- Enterprise-only client book: Profound, Brandlight or Promptwatch Enterprise.
If you would rather have a team handle the strategy while your tools do the tracking, an SEO and GEO agency like 1001 SEO Media can work alongside your reporting stack. For a wider look at the market, see the ranked lists at ai-rank-tools.com.
Bottom line
Gauge is not a bad tool, but at $599 a month with unconfirmed white-label features, it is hard to justify as the backbone of a multi-client practice without a trial. Test Promptwatch if you want to fix problems as well as report them, Rank Prompt if price per brand is the constraint, and ZeroRank or SE Ranking if client workspaces or an existing suite drive the decision. Then check the branding yourself before a client sees it.
