Explain principle working of message extension?
Message extensions allow customers to message you directly from your Google ad. Customers simply have to click on the call to action, such as “Send us a text” or “Message us for help.” Then, customers are taken to their messaging app where they can send you a text message.
Message extensions, like all other ad extensions, are eligible to show alongside an advertiser’s ads on the SERP, generally making them larger and more feature-rich while increasing CTR.
message extensions give users the opportunity to click to text a business directly from the SERP!
Advertisers can even include a pre-written text message to make starting that conversion easier for mobile users in a hurry.
Google Ads (formerly known as Google 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.
