In order to track calls back to your online advertising campaigns, you need to add Call Sumo's tracking code to dynamically display tracking numbers on your website.
The tracking code is a script we will provide you to help determine the advertising channel that led a visitor to your website and shows the tracking number that corresponds to that channel. Once the visitor calls your tracking numbers, the tracking code allows you to see the details of the visit as soon as the phone starts ringing.
Here's an example of how a tracking code looks like:
<script async src="//36039.tctm.co/t.js"></script>
You will need to add this code between the <head> and </head> of each page of your website. You can also ask your web developer to do this for you.
