What is Google Ads Call Tracking?

Google Ads call tracking is a set of features that help you measure how effectively your ad clicks lead to phone calls. When call reporting and phone call conversion tracking are enabled, Google can:

• show Google forwarding numbers in your ads or on your website,
• record call details like duration, start time, caller area code and whether the call was connected, and
• attribute calls to the keywords, ads, ad groups and campaigns that generated them.

Google uses Google forwarding numbers (GFNs) for this. These are temporary numbers owned by Google that forward calls to your real business line. They’re free to use as part of call reporting and website call conversion tracking, but they can change or be reassigned, and you can’t treat them as your permanent business numbers.

For businesses where the sales process depends on phone calls, such as home services, healthcare, legal, and high-ticket B2B sales teams, tracking calls is just as important as tracking form fills or online purchases. Phone calls often represent some of your highest-intent leads, and phone call conversion tracking in Google Ads helps you see which campaigns and keywords actually drive those conversations.

In more advanced setups, third-party call tracking tools and CRMs are used alongside native Google Ads call tracking. These tools record and analyze calls, tie them to contacts or deals, and then send Google Ads call conversions back into your account based on real outcomes (appointments, qualified leads or sales) instead of just call length.

How does Google Ads call tracking work?

At a high level, Google Ads call tracking connects three elements:

1. the user’s interaction with your ad,
2. the phone call that follows, and
3. the conversion logic you define (e.g., “count calls longer than 60 seconds as conversions” or “count only calls marked as qualified in my call tracking platform”).

Call reporting and Google forwarding numbers

When you enable call reporting, Google is allowed to use Google forwarding numbers in your ads and on your website (where eligible). Call reporting runs on these forwarding numbers and lets you measure performance for call assets, call ads, and calls to your website’s number.

Google can log:

• call start time and duration,
• caller area code,
• whether the call was connected or missed, and, in many regions,
• the caller’s phone number for calls longer than 15 seconds (with specific exceptions like India).

Phone call conversion tracking

On top of call reporting, you define one or more phone call conversion actions. Google currently supports several out of the box; calls from ads, calls to a number on your website, click-to-call events, and imported call conversions.

For each conversion action you configure:

• what counts as a conversion (e.g. minimum call length),
• how Google should attribute conversions, and
• whether Smart Bidding should optimize toward that conversion.

Once this is in place, Google can show you Google Ads call conversions alongside your other conversion types.

Imported call conversions

Imported call conversions are the bridge between native Google Ads call tracking and your CRM / sales team reality. Instead of relying on duration, you import conversion data from a call tracking tool or CRM whenever a call leads to a sale or other valuable action.

This is the most accurate way to measure calls because it trains Google on the same outcomes your sales team cares about.

How do I track calls in Google Ads?

To track calls in Google Ads, you always follow the same basic sequence, regardless of which specific method you choose later.

1. Enable call reporting
2. Create one or more phone call conversion actions
3. Implement the corresponding tracking method
4. Verify that calls and conversions are recorded correctly

The first step is turning on call reporting at the account level. This allows Google to use forwarding numbers and log call metadata. Without call reporting, native Google Ads call tracking cannot function.

Next, you create at least one phone call conversion action under Tools & Settings → Conversions. Google prompts you to choose what you want to track:

• calls from your ads,
• calls to a phone number on your website,
• someone making a call by clicking a number on your website, or
• calls you’ll track in another system and upload (import) into Google Ads.

Within each conversion action, you configure things like conversion name, value, and minimum call length so that very short or accidental calls don’t count as conversions.

Then you implement the tracking method that matches your choice:

• add a call asset or call ad if you’re tracking calls from ads,
• set up dynamic number insertion (DNI) and the Google tag if you’re tracking calls to your website’s phone number,
• configure click-to-call events in Google Tag Manager if you want to track clicks on phone links,
• or integrate a call tracking platform / CRM and follow Google’s workflow for importing call conversions when using offline or third-party data.

Finally, you verify that forwarding numbers appear where expected, that calls are showing in your reports, and that conversions are being counted according to your rules. When all of this checks out, your Google Ads call tracking setup is ready, and you can move on to refining which specific types of phone call conversions you want to rely on.

Before you go all Buzz on us, let’s see why Woody has a point and why thousands of marketers out there are turning to guides like this, to find an answer.

The 4 types of phone call conversions Google Ads can track

Google supports four core types of phone call conversion tracking:

1. Calls from ads – calls that start directly from call assets or call ads in the search results.
2. Calls to a phone number on your website – calls made to your site’s number after a Google Ads click, tracked via dynamic number insertion and forwarding numbers.
3. Click-to-call conversions – clicks on your phone number or call button, tracked as conversions even though the actual call isn’t measured.
4. Imported call conversions – calls tracked and evaluated by a third-party call tracking platform or CRM, then imported as conversions into Google Ads.

Each of these has its own strengths and limitations.

#1 – Calls from Google Ads

Google Ads Call Extensions add a phone number to your ads, making it easy for users to call your business directly from the ad.

If generating phone calls is a primary goal of your advertising campaign, call extensions make it easy for users to contact you directly.

Mobile users often prefer to call businesses directly rather than filling out online forms. Call extensions provide a convenient click-to-call option for these users.

Google Call-Only Ads are designed specifically to drive phone calls. If your business relies on phone interactions to close sales or book appointments (e.g., healthcare, legal services, home repairs), call-only ads are ideal because they facilitate direct contact.

When phone calls typically result in high-intent leads or immediate sales, call-only ads ensure that your advertising efforts focus on generating these valuable interactions.

For businesses that offer urgent or emergency services (e.g., locksmiths, emergency plumbers), call-only ads enable potential customers to connect with you instantly, addressing their needs promptly.

Below are the pros and cons of enabling conversion tracking for these types of conversions:

• Track when the call was placed, the call duration and the source.
• See summarized (not individual) data in Google Ads reports.
• Free of charge to activate.

• This method uses NON-UNIQUE Google Forwarding Numbers. This means that Google may have shown the number to an ad for another business.
• A lot of users are complaining of receiving calls asking for businesses not related to them but Google charges for each of these calls.
• Only available in the following countries.
• You also must have met the threshold of clicks in a 4 week period for Google to show and report your call conversions (for Desktop).
• Calls are tracked in total with no visibility on individual lead insights.
• On some calls, Caller ID shows a Google number, not the user’s number.

Good as an introduction to call tracking.
Unfortunately for marketers who are serious about their Google Ads setup and bidding strategy, the insights are limited and can sometimes skew performance rather than improve it.

Here’s an example:

You might see that campaign #1 drove 50 calls and campaign #2 drove 20 calls. This might indicate that campaign #1 performs better but this is only on the surface. In reality, campaign #1 might be driving non-quality or spam calls, so you might be wasting money on leads that don’t bring revenue.

#2 – Calls to a phone number on your website

When a user visits your website after clicking one of your ads, website call conversion tracking helps you identify and measure calls originating from your site.

This type of tracking considers a call as a conversion if it lasts longer than the minimum length you determine, allowing you to filter out shorter, potentially non-valuable calls.

• This setup enables you to evaluate which specific keywords, ads, ad groups, and campaigns are contributing to call conversions, providing valuable insights for your business.
• See summarized (not individual) data in Google Ads reports.

• This method uses NON-UNIQUE Google Forwarding Numbers. This means that Google may have shown the number to an ad for another business.
• Requires deep technical knowledge to set up.
• A lot of users are complaining of receiving calls asking for businesses not related to them but Google charges for each of these calls.
• Only available in the following countries.
• You also must have met the threshold of clicks in a 4-week period for Google to show and report your call conversions (for Desktop).
• Calls are tracked in total with no visibility on individual lead insights.
• On some calls, Caller ID shows a Google number, not the user’s number.

Very valuable for businesses that rely on phone calls for their day-to-day operations.

Unfortunately, you don’t get insights at the individual level (what was the call about, did the call result in a booking).

#3 – Click-to-Call Conversions

Conversion tracking is a crucial tool that helps you measure the effectiveness of your advertisements by showing how many users click on your business phone number on your mobile website or on-call ads and assets.

Unlike traditional phone call conversion tracking, which monitors the initiation of calls, this feature is dedicated to tracking the number of clicks on your phone number.

• You can track conversions from clicks on call ads, call assets, and the call button on location assets without using a Google Forwarding Number (GFN).

• You are not tracking actual calls.
• Conversion tracking is counted based on estimations after someone clicks your ad.
• Needs technical expertise to set up and use Google Tag Manager. Either you or your web developer will need to be able to add the tag to your website and add a JavaScript snippet with an onclick event handler.

Use this only as a last resort and if calls are not that important for your performance strategy.

Counting clicks and no calls can be misleading and skew your performance data.

#4 – Imported Call Conversions

Importing call conversions (automating uploading of phone call conversions in Google Ads) is the best and easiest option if your business relies on phone call leads.

A third-party call tracking software that integrates directly with Google Ads is essential for this to work.

Through a call tracking tool like Nimbata, you will be able to track calls from Google ads (including options #1 and #2 described above) and automate a process of having these phone call conversions in your Google ads account.

Comprehensive Call Analytics: Third-party call tracking software provides detailed analytics that go beyond basic call logs. It offers insights into call duration, call source, caller demographics, and even the conversation’s content through call recording and transcription.

Attribution Accuracy: These tools can precisely attribute calls to specific keywords, ads, or campaigns within Google Ads. This level of detail helps in assessing which elements of your advertising strategy are driving the most valuable calls, allowing for more effective budget allocation and optimization of ad spend.

Seamless Integration: Third-party call tracking solutions often integrate smoothly with various customer relationship management (CRM) systems, marketing automation platforms, and analytics tools. This integration ensures that all call data is synchronized across your marketing and sales ecosystems, providing a unified view of customer interactions and facilitating better decision-making.

Automated Reporting and Alerts: These tools can automate the generation of reports and real-time alerts based on predefined criteria. For instance, you can set up alerts for missed calls from high-value customers or generate reports that highlight trends and patterns in call activity.

Call Recording and Transcriptions: Many third-party solutions offer call recording and quality monitoring features. These tools allow you to review and analyze call interactions, knowing exactly which leads convert.

This is a paid solution that involves a license fee and usage costs.

If your business relies heavily on phone calls generated from Google Ads and you need advanced analytics, better attribution, and improved customer experience, using third-party call tracking software is a must.

Conclusion: Is Google Ads Call Tracking a good choice for me?

Well, the answer depends heavily on the objectives you have set for your own business.

If inbound calls do not contribute that much to your sales revenue, a solution like Google Ads call tracking might be a good option.

But if you count a considerable amount of phone conversions for your business, you should better make the most of them with a 3rd party call tracking software, such as Nimbata.

Call tracking doesn’t end at measuring performance but also helps businesses improve their interactions with customers.

To summarize, Google Ads call tracking provides meaningful insights into the campaigns, ads, and keywords that generate inbound calls for your business.

You don’t need to pay for fees and tracking numbers.

On the other hand, it’s a free tool with limitations compared to paid tools, which combined with Google can be a game-changer for your business…

Either way, you shouldn’t leave your phone calls unattributed!
