“Google launched a new AdWords tool called Website Call Conversions, which lets advertisers identify and measure calls from their website that occur after an ad click. The company explains that many customers only call a given business after clicking through an ad and learning more about the provided products and services. Google says 70 percent of mobile searchers have called a business directly from search ads, and the company already lets advertisers track this with AdWords click-to-call ads, call metrics, and calls as conversions. Today’s release is specifically for those calls that occur after already navigating to the company’s website” says the Next Web.
Convert Experiments call tracking integration will be updated as soon as Google publishes the way to hook into them. For now you can connect them in your Google Analytics where you will be seeing Convert experiment ID and variation name. Using a custom report you can connect the two. Read more here how to do this.
