Troubleshooting Dynamic Number Insertion

CallRail’s JavaScript snippet allows you to integrate call tracking on your website using dynamic number insertion (DNI).

If you expect a tracking number to swap on your website and are not experiencing the swap behavior, you can use the articles in this section to help you test and troubleshoot.

Getting Started

You must test each page where you’ve installed your JavaScript snippet separately. For example, entering a landing page URL will not test the entire website.

Note: If you're running an automated test using CallRail's auto-test feature, each test will check the web page for all tracking numbers in your company. In this case, you may see some tracking numbers show as “not found.”   

Troubleshooting Dynamic Number Insertion

Next, we’ve collected the most common errors that cause your numbers to stop swapping. If one of the sections below describes the specific issues you are experiencing, you can use the guide linked in that section to help you troubleshoot.

Where is the swap script placed?

It’s important that our swap script is as close as possible to `</body>` tag in your site's code. You can follow this guide for additional troubleshooting steps.

Is your site cached on your browser?

Try accessing your website in a private browsing session (like "incognito" mode on Google Chrome). If you suspect this to be the case, we strongly recommend testing your website on a computer that has not been to the site previously. Alternately, if no computer is available, please contact our Support team and we’ll be happy to verify your number’s swapping for you.

Is your swap target correct?

The swap target is the telephone number CallRail looks for on your website to dynamically replace with a tracking number. If the swap target is incorrect, your numbers won't swap. You can follow this guide for additional troubleshooting steps.

Is your swap target formatting correct?

If you notice your numbers are not swapping, check your swap target formatting. You can follow this guide for additional troubleshooting steps.

Is another tracking number swapping instead of a tracking number from your website pool?

If your numbers are not swapping, make sure you read through CallRail's swap precedence rules to make sure you’re not accidentally overriding your website pool with other tracking numbers.

Are you using caching plugins?

Certain plugins, like WP Rocket, can cause the JavaScript snippet to fail. You can follow this guide for additional troubleshooting steps.

If you are still having issues after following the troubleshooting steps in the guides provided, please contact our Support team.
