Phone number click as a Google Ads conversion

Short answer: A tap on a tel: link tells you a phone opened a dial screen. It does not tell you a call happened. Use it as a secondary action, or as the main one only if every call is worth the same to you. For a count of real calls, use Google's website call conversion, which counts a call only when it lasts longer than a minimum length you set. On 9 Nov 2026 we read the public GTM containers of 857 study sites with Google Ads conversions: 45 (5.3%) fire one on a tel: click and 29 (3.4%) on a mailto: click.

How many sites count a phone or email click?

On 9 Nov 2026 we rescanned the public Google tag and GTM containers of the 886 sites with a readable Google Ads conversion in the 1,727-site study. 29 of them share a container with another site in the list, so the base is 857. We counted a site when a Google Ads conversion tag has a click trigger whose link URL condition contains tel: or mailto:.

The button click guide leaves these out on purpose. Google names a tap on a phone number as an example of a click worth counting. The question is what the tap tells you.

What is the difference between a tel: click and a call conversion?

Google's own help page for the click version talks about phone number clicks on a mobile website. On a desktop browser a tel: link may open nothing, or an app the visitor never set up. If the trigger has no device condition, desktop clicks count too.

What about a mailto: click?

A mailto: click opens a mail app with a blank message. Nobody has sent anything yet. It is the same problem as a form: a click that comes before the lead. 29 sites count it, 23 of them next to a tel: click. If an email request is worth money to you, count the one you can see: a contact form success, with a transaction ID if you can (Google Ads Help). See transaction IDs on lead forms.

Which one should I use?

• You get a few calls a week and every one counts: the tel: click is fine as a secondary action. It shows whether the phone link gets used.

• Calls are a main lead source: set up the website call conversion with a minimum call length that fits your sales calls. Then make that the primary action, not the click.

• You already use a call tracking tool: import its calls (Google Ads Help names the import option) and keep the click as secondary.

• Both in Google Ads as primary: one call can count twice, once as the tap and once as the call. See duplicate conversions in GTM.

How do I check my own site?

DevTools, Network, Preserve log, filter conversion. Click your phone number and your email address. A request with label= means that click is a conversion. Open the page on a laptop as well as a phone: if it still fires, the trigger has no device condition. In GTM, open each trigger on a Google Ads tag and look for Click URL contains tel: or mailto:. In Google Ads (Goals, Conversions), see whether the action is Primary.

How do I fix it?

• Make the click action secondary, don't delete it. Note 30 days of Conversions first: the count drops by the taps that never became a call.

• Add the call conversion and set the minimum call length. Check a test call shows up before you make it primary.

• Count the form, not the mailto: put the success event on the Ads action. Click conversions covers the other buttons.

What can't we see from outside?

• Primary or secondary. The 5.3% and 3.4% are sites where a phone or email click is set up as a conversion, not where it is bid on.

• Website call conversions. They run through a phone snippet and Google's forwarding numbers. We can't tell from a container whether a site uses one, or what minimum length it set.

• How good the calls are. We see the tag, not the call.

• Device conditions and call tracking tools that fire on the server or in a script outside GTM, and GA4 events imported into Ads.

FAQ

Is a tap on a phone number a valid Google Ads conversion?

Yes, Google lists it as an example of a click conversion. It counts the tap, not a call, so many teams keep it as a secondary action.

What is a website call conversion?

Google swaps your number on the page for a forwarding number and counts a call when it lasts longer than a minimum length you set.

Should a mailto: click be a Google Ads conversion?

Not as a primary one. It opens a blank message and nobody has sent anything yet. Count the form success instead.
