A Hands-On Review of WhatConverts for PPC Agencies

If you run a PPC agency, you already know the truth: clients don't care how many clicks you bought them. They care how many phone calls rang, how many forms filled, and how much revenue showed up in the bank. The gap between "Google Ads conversions" and "actual leads my client closed" is where agencies either prove their worth or quietly lose accounts.

I've spent the last several months running WhatConverts across a handful of agency client accounts spanning home services, legal, and B2B SaaS. This is the hands-on review I wish I'd had before signing up. No affiliate fluff, no "top 10 features" filler. Just what worked, what didn't, and whether it's the right pick for your agency stack.

The Short Answer for Busy Agency Owners

WhatConverts is the strongest dedicated lead-attribution platform for PPC agencies that need to prove ROI on phone calls, forms, and chats across multiple clients. The agency dashboard, white-label options, and value-based reporting are genuinely better than what I've seen in CallRail for multi-client workflows. It's not the cheapest option, and the UI has some 2018-era rough edges, but the data quality and Google Ads integration make it worth the spend if call-driven leads are core to your clients' business.

If your clients run mostly e-commerce and don't care about phone leads, you probably don't need it. If even 20% of their conversions come from calls, forms, or chats, keep reading.

What WhatConverts Actually Does (in Plain English)

At its core, WhatConverts answers one question for every lead: "Which marketing dollar created this?"

It does this through four tracking primitives:

• Dynamic Number Insertion (DNI) swaps the phone number on your client's site based on the visitor's source. A Google Ads click sees a different number than an organic visitor, so when they call, you know exactly which campaign and keyword drove the call.
• Form tracking captures form submissions without you having to modify the form code. It just listens.
• Chat tracking ties live chat conversations back to the originating campaign.
• eCommerce conversion tracking for clients with online checkout.

All four feed into one unified "lead" object you can score, qualify, value, and push back to Google Ads, Meta, GA4, HubSpot, or wherever your client lives. That last bit, pushing real lead values back to ad platforms, is the magic. You're no longer optimizing toward "form fill" as a flat conversion. You're optimizing toward "qualified lead worth $4,200."

Setup: How Long Until It's Actually Working?

I'll be honest, the first account took me about 90 minutes from signup to first tracked call. The next ones took 20-30 minutes each once I knew the workflow.

The steps are roughly:

1. Add the WhatConverts tracking script to the client site (Google Tag Manager works fine).
2. Provision a tracking number pool, usually 5-15 numbers depending on traffic.
3. Configure DNI rules: which sources see which numbers.
4. Connect Google Ads, GA4, and Meta via their native integrations.
5. Set up form selectors (the auto-detector caught about 80% of forms; the rest needed manual CSS selectors).

The one part that genuinely tripped me up was getting call recording compliance right for multi-state clients. WhatConverts has the dual-consent message feature built in, but you have to explicitly enable it per client profile, and the documentation is buried. If your agency has clients in California, Florida, or Pennsylvania, write that step into your onboarding SOP.

The Agency Dashboard: Where WhatConverts Pulls Ahead

This is the headline feature for agencies. The agency-level dashboard lets you toggle between client accounts in one click, run cross-client reports, and apply white-label branding to client-facing views.

What I genuinely like:

• Switching accounts is fast. No re-login, no account picker hellscape. One dropdown.
• White-label is clean. Your logo, your domain (CNAME), your colors. Clients see your brand, not WhatConverts'.
• Permission controls are granular. I can give a junior media buyer read-only access to one client without exposing the whole roster.
• Bulk number provisioning saved me hours when onboarding a client with 12 service-area landing pages.

What I don't love:

• The cross-client reporting is decent but not as flexible as I'd like. You can't easily build something like "show me cost-per-qualified-lead across all home-services clients for Q1." You'd export to a sheet and pivot.
• The dashboard styling feels dated. It works, but it doesn't have the polish of newer attribution tools.

Lead Attribution Accuracy: The Real Test

I ran a side-by-side test for one client where I left their existing CallRail account active and ran WhatConverts in parallel for 30 days.

The two platforms agreed on the source for about 94% of calls. The 6% where they disagreed almost always came down to multi-touch edge cases: a user clicked a Google Ad, came back via direct, and then called. CallRail credited direct; WhatConverts credited the original Google Ad click via its first-touch attribution model. WhatConverts' answer was more useful for optimizing ad spend, since the ad was the actual source of the lead.

The AI lead qualification, which auto-listens to call transcripts and tags leads as qualified, billable, or junk, was about 85% accurate by my count. Not perfect, but a massive time-saver versus listening to every call manually. It's especially good at filtering out spam calls, telemarketers, and existing customers calling support.

Value-Based Bidding: Where It Pays for Itself

This is where WhatConverts genuinely changed how I run accounts. Instead of pushing "phone call" as a binary conversion to Google Ads, I push lead value. A 12-second hangup gets $0. A 4-minute qualified consultation request gets the client's average deal value. Google Smart Bidding then optimizes toward the dollars, not the rings.

For one home-services client, switching from "all calls" to "qualified calls with value" as the conversion action dropped their cost-per-qualified-lead by 31% over six weeks while spend stayed flat. That's the kind of result that pays for the tool ten times over.

Pricing: The Honest Numbers

WhatConverts uses a tiered model based on tracked leads per month, not seats. Plans start around $30/month for the smallest tier and scale up based on lead volume. For a typical PPC agency client with 200-500 tracked leads/month, you're looking at the $80-$200/month range per client account.

For an agency, the math works like this: if you bake $150/month of WhatConverts cost into a $2,500/month retainer, your margin is fine and your client retention goes up because you can prove ROI in dollars, not vanity metrics. If you try to absorb it on a $500/month retainer, it'll squeeze you. Price your retainers accordingly.

Is it cheaper than CallRail? Roughly comparable at the lower tiers. Slightly more expensive at high lead volumes, but the agency-tier features justify the premium for most multi-client setups.

Where WhatConverts Falls Short

No review is honest without the warts.

• The UI feels dated. Functional, but you can tell the design language hasn't been refreshed in a while. Compare it to a tool like Hyros and the gap is visible.
• No native server-side tracking in the same way Hyros offers. If your clients run iOS-heavy traffic and you're losing data to ITP, you may want a complementary tool.
• The mobile app is mostly read-only. Fine for checking lead counts on the go; useless for actual configuration.
• Custom integration setup can be painful. The Zapier and webhook options work, but expect to read documentation.
• Spam filtering on form submissions isn't as aggressive as I'd like. We had to layer hCaptcha on top.

Who Should Actually Buy This

WhatConverts is a strong fit if you're:

• A PPC or full-service agency with 5+ clients where phone or form leads matter.
• Running Google Ads as a primary channel and want to feed real lead values back to Smart Bidding.
• Tired of explaining to clients why "Google says 47 conversions" but their CRM only shows 12 real leads.
• Looking for white-label reporting that doesn't make you look cheap.

It's probably not for you if:

• You only run e-commerce clients with checkout-based conversions.
• You have one client and don't need multi-account features. (CallRail's solo-business tier might be cheaper.)
• You need military-grade server-side ad tracking; look at Hyros instead.

My Verdict After 6 Months

WhatConverts is now my default recommendation for PPC agencies running call-driven verticals. The lead attribution data quality, the agency dashboard, and the value-based bidding integration with Google Ads are genuinely best-in-class for the agency use case. Yes, the UI could be better. Yes, you'll occasionally curse at the documentation. But it does the one job an agency actually needs, prove ROI in real dollars, better than anything else I've tested in this category.

If you're still relying on "Google Ads conversions" as your reporting source of truth, you're flying half-blind. Pick a real attribution tool. WhatConverts would be my first call.

Frequently Asked Questions

How does WhatConverts compare to CallRail for PPC agencies?

Both are solid, but WhatConverts has the edge for agencies running 5+ accounts thanks to faster account switching, better white-label, and stronger value-based reporting. CallRail's UI is more polished and its conversation intelligence is slightly more mature. For pure call tracking on a single account, CallRail is fine; for multi-client agency workflows where you need to prove ROI in revenue terms, WhatConverts wins.

Can I white-label WhatConverts for client reporting?

Yes, fully. You can use a custom CNAME, your own logo, and brand colors so clients never see the WhatConverts name. White-label is included on the agency plans, not on the entry-level individual plans, so check your tier.

Does WhatConverts work with Google Ads Smart Bidding?

Yes, and this is one of its strongest features. You can push lead values, not just conversion counts, back to Google Ads. Smart Bidding then optimizes toward actual revenue, which typically lowers cost per qualified lead substantially within 4-8 weeks.

Will WhatConverts slow down my client's website?

The tracking script is asynchronous and lightweight, around 30KB. In my testing, it added under 50ms to load time. Use Google Tag Manager to load it and you're fine. It will not move your Core Web Vitals score in any meaningful way.

How accurate is the AI lead qualification?

In my testing across about 1,200 calls, the AI agreed with my manual qualification on roughly 85% of leads. It's especially good at flagging spam, telemarketers, and existing-customer calls. For high-stakes accounts, I still spot-check 10% of qualified calls weekly, but it has saved me hours per week per client.

Is WhatConverts overkill for a small agency with 2-3 clients?

It depends on those clients. If they're high-ticket service businesses where one missed lead is a $5K problem, WhatConverts pays for itself fast. If they're low-ticket e-commerce, it's overkill, look at simpler call tracking or stick with native Google Ads conversion tracking. Read our guide on choosing attribution tools for a full decision framework.

Can I export WhatConverts data to Looker Studio or another BI tool?

Yes. There's a native Looker Studio (formerly Data Studio) connector, plus standard CSV export, webhook push, and Zapier. For agencies running custom dashboards, the Looker Studio connector is the cleanest path. API access is also available on higher tiers if you want to build your own integration.
