Measuring the real ROI of campaigns targeting WhatsApp is one of the biggest challenges for any performance manager. The reason is simple: WhatsApp is a closed environment, a black box that our pixels and online tracking systems can’t penetrate.
The easy and wrong way is to measure the “click” on the wa.me link as a conversion. This gives us a false sense of success, but it’s actually a vanity metric that inflates results and leads us to make bad decisions.
Here’s the real problem, broken down:
A Click Is Not a Lead: A user (or a bot) can click, see the pre-loaded message on WhatsApp, and close the app without typing a single word. If we count that click, we’re recording “conversions” from people who never showed any real interest. Or worse, clicks generated by bots. We’re optimizing our campaigns toward a valueless event.
The Attribution Break: The moment the user leaves the browser to open WhatsApp, we lose track of them. The click from Google Ads or Meta is orphaned. The conversation that follows, which is where the real lead is generated, happens in an “offline” universe for the platforms. There’s no native way to tell them: “Hey, remember that click from 5 minutes ago? It just became a qualified lead.”
Faced with this scenario, at Waukin Media – Search Engine Marketing Agency (SEO and SEM), we have integrated tochat.be, a tool that acts as the bridge we needed between the online world of the ad and the offline world of the conversation.
I wrote to its founder, César Martín, to thank him, because now we can robustly solve these points of friction:
✅ We connect the online and offline worlds: We capture click identifiers before the user enters WhatsApp. When the conversation starts, we can send that data back to Google Ads through Enhanced Conversions. Attribution becomes accurate and real.
✅ We generate valuable conversions in GA4: We’ve stopped measuring clicks and instead recorded “lead_real” events only when a user sends the first message. This completely eliminates the noise of unengaged clicks and bot traffic.
✅ We automate audience intelligence: By correctly identifying leads, we can automatically send that data to Meta and Google to create more effective remarketing audiences.
In short, we’ve gone from optimizing with inflated data to optimizing based on real business value. The impact on campaign performance is direct.
Great work, Cesar. Tools that solve measurement infrastructure problems are what really make the difference.
