Message extensions give users the opportunity to click, to text a business directly from the ad! Advertisers can even include a pre-written text message to make starting that conversion easier for mobile users in a hurry.
There is however one caveat – there is no conversion tracking. Advertisers who want to see how many texts their message extensions are generating have to create their own system to track and measure the success of their message extensions.
AdWords advertisers are charged the same CPC fee when a user clicks on a message extension as if they clicked on the ad’s headline or another ad extension.
Keep an eye out for this extension within your account as Google plans to roll them out to advertisers in different regions!
