How to track WhatsApp conversions in Google Ads

If your customers talk to you on WhatsApp, as most do in Brazil, the most important conversion in your campaign is the click on the WhatsApp button. Without tracking it, Google Ads does not know which searches bring leads and optimizes blind. The basic setup takes a few minutes.

Why track it

Google Ads only improves what it can measure. If the campaign only records ad clicks, it will chase more clicks, not more customers. With a WhatsApp conversion set up, you see which keywords and ads start conversations, what each lead costs, and you can use automated bid strategies focused on leads.

Step 1: create the conversion action

  • In Google Ads, go to Goals → Conversions → New conversion action → Website.
  • Create a conversion called, for example, "WhatsApp click", category Contact.
  • Under count, choose One (several clicks from the same person count as one lead).
  • Copy the event snippet (the send_to, in the format AW-XXXXXXX/XXXXXXX).

Step 2: fire the conversion on click

Your site needs to tell Google when someone clicks a WhatsApp link (addresses starting with wa.me or api.whatsapp.com). There are two ways:

  • Google Tag Manager: a "link click" trigger with the URL containing wa.me, connected to a Google Ads conversion tag.
  • Code on the site: a small script that, when the button is clicked, fires the conversion event with the send_to from step 1.

After publishing, test it: click the button and check in Google Ads that the conversion shows as recorded (it can take a few hours).

Step 3: know who actually closed

A WhatsApp click is intent, not a sale. To go further:

  • Ask how the person found you, or use a different pre-filled message for Google ("I found you on Google").
  • Note in your records (spreadsheet or CRM) which leads became customers.
  • More advanced accounts can import sales back into Google Ads (offline conversion import), so the algorithm learns who actually buys.

Common mistakes

  • Counting the same person several times ("Every" count instead of "One").
  • Tracking only a form thank-you page and forgetting WhatsApp.
  • WhatsApp buttons on pages where the Google tag is not installed.
  • Using the conversion code without the label (just AW-XXXXXXX): Google does not record it.

Frequently asked questions

Does Google Ads track WhatsApp conversations on its own?

No. It tracks the click on the WhatsApp button on your site, if you set up the conversion. Google cannot see what happens inside the conversation.

Do I need Google Tag Manager?

It is not required, but it makes things easier. You can also fire the conversion with a small piece of code on the site itself.

How long does it take for the conversion to show?

Usually a few hours. In some cases, up to a day.
