"Webmatch" is a call-tracking feature provided by Callcap that associates phone calls with specific pageviews to bridge the gap between advertising campaigns and incoming phone calls.
Webmatch allows a company to bridge the gap between basic web analytics and direct sales via phone calls. If a call leads to a sale, Webmatch can help you see where the initial visit came from, what ad campaign it may have run under, and what page the user was on when they called you.
At it's most basic, Webmatch will simply associate recent calls to recent pageviews, but with Dynamic Rotator enabled, Webmatch can show unique phone numbers to visitors to more accurately track their statistics.
In order for the Callcap Webmatch plugin to work, you must have Webmatch enabled on your Callcap account. More information can be found here:
