What is call tracking?
Call tracking is a way to find out which marketing produced a phone call. The usual method is to give each source, such as a Google ad, a website, or a printed mailer, its own phone number. Each number forwards to the business's real line. When someone calls, the system records which number they dialed, and with it the source, along with details such as the time and length of the call.
For a business that books work by phone, ad platforms and analytics tools don't see a call unless something connects it to its source. Call tracking provides that connection.
How does call tracking work?
Most systems follow the same pattern. Google describes its own version for Google Ads in four steps:
- Display: a tracking number "is displayed in your call assets or your website (for call conversion tracking) instead of your business number."
- Tracking: when someone calls it, "Google Ads tracks details about the call like time, duration, campaign, and ad group."
- Routing: the call is automatically routed "to your actual business phone number."
- Reporting: the details appear in reports.
Third-party call tracking platforms apply the same idea to sources outside Google Ads, such as organic search, the Business Profile, and printed ads.
What is dynamic number insertion?
Dynamic number insertion swaps the phone number shown on a website based on how the visitor arrived, so a call from that visitor can be tied to their source. Google Ads includes its own version for website calls. Its phone snippet "replaces a phone number on your website with a Google forwarding number," so Google can connect a call to the ad that brought the visitor and see "which specific keywords, ads, ad groups, and campaigns are leading to call conversions."
Google adds that it can do this "without any cost to you." The swap only applies to visitors who clicked an ad; everyone else sees the regular number.
How does Google Ads count calls as conversions?
Google Ads can count a call as a conversion in two ways: "by analyzing call recordings using Google's AI to identify high-quality leads, or by counting calls that last longer than a minimum duration you set." If recording is off or unavailable, Google falls back to the minimum duration.
Google notes that call recording "is currently limited to calls where both parties are in the U.S. or Canada." Setting the minimum length matters: too short, and quick hang-ups count as conversions; too long, and short booking calls are missed.
What rules apply to Google forwarding numbers?
Google sets limits on its own tracking numbers:
- Don't reuse them. Google forwarding numbers "shouldn't be copied and promoted outside of Google Ads," because they "are a property of Google and can change or be reassigned at any time."
- They expire. Calls connect for 60 days after a caller's first call, and each new call resets the 60 days.
- First calls need to be quick. A first call connects if it's placed within "about 30 minutes (up to about 2 hours in certain markets) of viewing the ad."
For numbers printed on trucks, yard signs, or mailers, use the business's own numbers or numbers from a call tracking platform the business controls.
Can call tracking numbers hurt local SEO?
Google's Business Profile guidelines set the rules for phone numbers on a profile:
- "The phone number must be under the direct control of the business."
- "Use a local phone number instead of a central call center helpline number whenever possible."
- Numbers and URLs must not redirect users to "landing pages or phone numbers other than those of the actual business."
- "Additional phone numbers can be used on Google Business Profile websites and other local surfaces."
Google doesn't say tracking numbers affect rankings. Because Google also compiles business details from other sources, using numbers consistently across listings matters. See what are local citations.
What should a moving company track?
At minimum, a separate number or tracking method for each paid channel, the website, and the Google Business Profile. Then connect the calls to outcomes: which calls became booked moves. Calls that start online but book offline can be reported back to Google Ads; see offline conversion tracking.
