I've set up a new AdWords account and can include your phone number in the ad. The Google Adwords hotline is closed on the weekend. I ask you here.
If a user does not click on the ad and calls the number, how does Google track and calculate the AdWords user?
Another thing: I already get a call at least once a week from sellers trying to sell me a mostly useless or overpriced product (real estate). I think adding my phone number could lead to more sales.
Any feedback from Adwords users?
