Google Ads Phone Call Tracking: How to Record Call Conversions Correctly
If your business relies on phone enquiries, accurate call tracking is one of the most important parts of your Google Ads account.
Unfortunately, many businesses unknowingly over-report phone call conversions because of incorrect tracking settings. This can make campaigns appear more successful than they actually are and may cause Google’s Smart Bidding algorithms to optimise towards inaccurate data.
In this guide, we’ll explain how Google Ads phone call tracking works, the difference between “One” and “Every” conversions, why minimum call duration matters, and the most common mistakes we see when auditing Google Ads accounts.
What is Google Ads Phone Call Tracking?
Google Ads allows businesses to record phone enquiries as conversions.
Calls can be tracked from:
• Click-to-call ads
• Call assets (formerly Call Extensions)
• Phone numbers displayed on your website using a Google Forwarding Number
These conversion actions help advertisers understand which keywords, campaigns and ads are generating valuable enquiries.
One vs Every: Which Setting Should You Use?
Every conversion action includes a setting called Count.
There are two options.
One
Google records only one conversion per ad interaction.
Example:
A user clicks your ad and calls your business three times.
Google records one conversion.
This is generally the recommended option for lead generation businesses because the objective is usually to measure unique enquiries.
Examples include:
• Electricians
• Plumbers
• Dentists
• Lawyers
• Accountants
• Real estate agencies
• Medical clinics
Every
Google records every conversion after an ad interaction.
Using the same example above:
A user clicks your ad once but calls your business three times.
Google records three conversions.
This option is usually more appropriate for eCommerce businesses where multiple purchases from the same customer have value.
Why Minimum Call Duration Matters
Not every phone call is a genuine lead.
Examples include:
• Wrong numbers
• Missed calls
• Spam calls
• Hang ups
• Existing customers
If your minimum call duration is set too low—or isn’t configured at all—Google may record these interactions as conversions.
For many businesses, a duration between 30 and 60 seconds provides a more reliable indicator of a genuine enquiry. However, the ideal duration will vary depending on your industry and average call length.
Website Calls vs Calls From Ads
Many advertisers don’t realise these are different conversion types.
Calls from Ads
These occur when someone taps the phone number shown directly within a Google Search Ad.
Calls from Website
These require a Google Forwarding Number to dynamically replace the phone number on your website after someone clicks your ad.
If this isn’t configured correctly, website phone enquiries may not be recorded accurately.
Frequently Asked Questions
Should I use One or Every?
For most lead generation businesses, One is recommended.
If you’re measuring enquiries rather than purchases, duplicate phone calls generally shouldn’t be counted as additional conversions.
What is a good minimum call duration?
There isn’t a universal setting.
Many businesses start between 30–60 seconds, but this should reflect what typically qualifies as a genuine enquiry.
Why do my Google Ads conversions differ from my CRM?
Google Ads records conversions based on its attribution model, while CRMs usually record unique leads.
Differences can also occur because of attribution windows, repeat callers, offline enquiries or incorrect conversion settings.
Can Google track calls from my website?
Yes.
Google Ads can track website calls using a Google Forwarding Number, provided it has been correctly implemented.
Conclusion
Phone call tracking is often overlooked, but it has a significant impact on campaign performance.
Small configuration mistakes—such as using the wrong conversion count setting or failing to apply a minimum call duration—can distort your reporting and affect Google’s automated bidding.
If your Google Ads conversions don’t align with the enquiries you’re actually receiving, it’s worth reviewing your tracking configuration.
