Google Ads Call Tracking Setup

We set up Google Ads call conversions for call assets, website calls and click-to-call taps, with duration thresholds and optional call tracking platform integration. For businesses whose best leads pick up the phone instead of filling in a form.

Local services, healthcare, legal and home service businesses that rely on phone calls

01 The problem

Phone Calls Are Often Your Invisible Conversions

When phone calls are not tracked, the campaigns that drive them look unprofitable, and Smart Bidding pulls budget away from the searches that make your phone ring.

  1. 01

    Calls Missing From Reports

    Visitors who read the site and dial the number from a desktop or another phone leave no trace in Google Ads.

  2. 02

    Every Tap Counted

    Tracking only click-to-call taps counts accidental taps and hang-ups the same as a real booked job.

  3. 03

    No Link to Call Outcome

    Without a call platform or CRM link, a short wrong number call and a long sales call carry equal weight.

02 What we implement

The Call Conversions We Configure

We cover the three ways Google Ads can see a call: calls from ads, calls from your website and taps on phone links, each with its own conversion rules.

  • 01

    Call Asset Conversions

    Calls from ads counted as conversions once they pass a minimum duration you define.

  • 02

    Website Call Conversions

    Google forwarding numbers swapped onto your site so calls from ad visitors can be attributed.

  • 03

    Click-to-Call Tracking

    tel: link clicks tracked in GTM as a secondary action for mobile engagement reporting.

  • 04

    Duration Thresholds

    Call length rules set per action so short or accidental calls do not count as conversions.

  • 05

    Call Platform Integration

    CallRail, CallTrackingMetrics or similar tools connected to import qualified calls with GCLID.

  • 06

    Call Reporting Setup

    Call details reporting enabled so caller area code, duration and campaign are visible.

03 Live data flow

How a Phone Call Becomes a Conversion

A forwarding number links the call to the ad click, and a duration rule or call outcome decides whether it counts.

07 FAQ

Call Tracking FAQ

Something else? Talk to GrowthUper

What is the difference between call asset and website call conversions?

Call asset conversions count calls made directly from your ad, such as tapping the call button in search results. Website call conversions count calls made to a Google forwarding number shown on your site after someone clicked an ad.

Will number swapping affect our local SEO?

The Google forwarding number only replaces the number for visitors arriving from Google Ads, using JavaScript after the page loads. Your number in the page source and business listings stays the same, which keeps your contact details consistent for search.

What call duration should count as a conversion?

It depends on your business. A short call might be enough for a booking line, while a sales call may need several minutes to mean anything. We look at typical call lengths with you and set a threshold that filters out wrong numbers and hang-ups.

Do we need a paid call tracking tool?

Not always. Google forwarding numbers cover many accounts at no extra cost. A tool like CallRail adds recordings, call scoring and multi-channel attribution, which is useful if you want to import only qualified calls.

Can calls be counted based on whether they became a sale?

Yes, when a call tracking platform or CRM records the outcome. Those qualified calls can be imported into Google Ads as offline conversions, tied to the ad click through the GCLID captured by the call tool.
