How dynamic number insertion works
There are several ways you can install dynamic number insertion on your website. Here are our other articles that will guide you through these methods:
Destination number: The number that rings at your business when one of your tracking numbers is called. This is where your calls are routed. Usually, your business number.
Swap target: The swap target is the telephone number CallRail looks for on your website to dynamically replace with a tracking number. By default, the swap target is the destination number.
Source tracking number: A single, static tracking number that tracks one campaign source. For example, a billboard or a Google ad extension.
Website pool: A pool of numbers that dynamically swap based on how a lead routes to your website and is able to capture visitor-level data like pages visited, PPC keywords, etc. This also allows for more extensive lead reporting like CPL and keyword reporting.
Cross-subdomain call tracking
By default, every CallRail account is set up to track across subdomains. Cross-subdomain tracking allows your website visitor’s referring data to be carried across subdomains. This allows CallRail’s dynamic number insertion script to show the same tracking to a visitor as they navigate across subdomains on a website (i.e. from http://campaign.example.com to http://example.com).
