How to Set Up Call Tracking

This guide takes you from zero to a working tracking number. No prior experience needed. By the end, you will have a number that forwards to your phone and a report that shows which ad made it ring. Set aside about fifteen minutes.

Set up your first tracking number

Follow these steps in order. They apply to almost any call tracking tool, with small wording changes. We use general terms so the steps work whether you pick CallScaler, CallRail, or WhatConverts.

1. Create an account

   Sign up for a call tracking tool. Pick one with a free or low-cost entry so you can practice without risk. CallScaler has a $0 starting tier, which makes it an easy place to learn.

2. Buy or claim a tracking number

   In the dashboard, find the option to add a number. Choose a local number with an area code your customers know, or a toll-free number if you serve a wide area. The tool provisions it in under a minute.

   Tip: a local number often gets more answers than a toll-free one, because callers trust a familiar area code.

3. Set the forwarding number

   Tell the tool where to send calls. This is your real business phone, a cell, or a front desk line. Calls to the tracking number now ring through to you.

4. Place the tracking number where it belongs

   For an offline ad, print the tracking number on the ad. For a single online campaign, put the number on that campaign's landing page. For a whole website, use dynamic number insertion, covered in step five.

5. Turn on dynamic number insertion if you have a website

   If you want to know which online source drove each call, add the tool's small snippet of code to your site. It swaps the number based on how each visitor arrived. The DNI guide shows exactly how this works.

   Tip: most tools give you a single line of code to paste before the closing body tag. If you use a site builder, there is usually a header or footer code box for this.

6. Make a test call

   Dial your tracking number from your own phone. Confirm it rings through to the forwarding line. Then open the dashboard and check that the call shows up with the right source. This proves the setup works before real customers call.

7. Read your report after a few days

   Give it a few days to gather data, then open the call report. Look at which sources drive calls and which do not. Now you can move budget toward what works.

Connect call tracking to Google Ads

If you run Google Ads, you will want your call data inside Google so the platform can optimize toward calls. Most call tracking tools have a built-in Google Ads connection. You turn it on, sign in to your Google account, and the tool sends calls back as conversions.

This is different from the call extensions Google offers on its own. Google's own call assets documentation covers the built-in feature. A dedicated call tracking tool adds source detail that Google's basic feature does not. We compare the two in the call tracking vs Google Ads call extensions guide.

Common setup mistakes to avoid

A few small errors trip up beginners. Here is how to skip them.

Replacing your main business number everywhere

You do not need to change your main line. Tracking numbers forward to it. Keep your real number on Google Business Profile and legal pages, and use tracking numbers for ads and campaigns. Some setups keep your main number for organic visitors and only swap it for paid traffic.

Forgetting to test the forwarding

Always make a test call before you launch. A number that does not forward correctly means missed customers. The test call in step six takes one minute and saves real money.

Not waiting long enough to judge results

One day of data is not enough. Give each source a week or two so you have enough calls to trust the pattern. Judging an ad on three calls leads to bad decisions.

What a good first month looks like

In your first month, aim for three things. First, every ad and major page has the right number and forwards correctly. Second, your report clearly shows the source of each call. Third, you make at least one budget decision based on the data, like pausing a weak source or adding spend to a strong one. If you hit those three, your setup is doing its job.

Which tool to start with

Now that you know the steps, the tool choice is easier. For learning, we suggest the one with the simplest start and the lowest cost to practice. That is CallScaler for most beginners, with a free tier and short setup. CallRail is a polished, popular option, and WhatConverts is strong if lead-source reporting is your focus.
