How to track message extension.conversions?
I am running AdWords campaign for one of my UK client. since two weeks I've implemented message extension. Within 14days I got 11 clicks but conversion is not showing.
My question is that how to track the conversion from message extension. How Adwords system knows that conversion happened.
See , 11 clicks that means 11 message has delivered to the mobile numbers.
Someone kindly explain briefly how message extension work..
