What is Call Tracking

Call tracking technology is used by marketers to track phone calls to measure conversion rate along with additional analytics such as duration of the call and call routing options. It's normally used in a pay per call performance-based advertising business model.

Better data. More great leads.

The possiblities for advertising are multiplying. From billboards to bus shelters, display ads to directories, web searches to websites, it can be challenging to figure out what tactic will lead to the most conversions. Luckily, call tracking can help cut through the confusion.

Traditionally, call tracking required businesses to hook up phone lines and invest in expensive hardware. Configuring on-premise infrastructure required serious technical chops.
