Using CallRail for Dynamic Number Insertion


CallRail’s dynamic number insertion feature helps you quickly integrate call tracking in your landing page. Each tracking number you create can be assigned a source (like Google Ads, Bing Organic, Yelp, Facebook, etc.) and the correct tracking number will display when a user reaches your landing page via one of these sources.

You will be able to track campaigns in the US, Canada, United Kingdom, Australia, New Zealand, France, Germany or Brazil.

1. Click Settings at the top of the page;


2. Choose the company whose JavaScript code you’d like to install;


3. Select All Integrations from the Integrations section in the left menu;


4. Choose Dynamic Number Insertion from the list of available integrations;


5. Copy the JavaScript provided;


6. Go back to the Instapage builder and click on Settings;


7. Click on HTML/CSS;


8. Paste the code snippet in the Footer section.


Then, create tracking numbers within your CallRail account to track visitors from a specific source, like Google Ads. When a visitor navigates to your landing page through one of the sources you’re tracking, CallRail’s JavaScript will detect the phone numbers on your web page and swap them with the correct tracking number. They will then store the visitor’s source in a cookie so they’ll continue to see the same tracking number each time they return to your website (unless swap.js is removed).
