I enabled Extensions within one of my Adwords campaigns and was surprised to see a report within my account about Extension activity.
I activated Extensions by connecting my Adwords account to an approved Google Places account which in turn then pushes its data into my Adwords account.
I was surprised this particular ad generated as many impressions as it has.
Next, I am going to add multiple Google Places accounts and locations to a multi-unit Adwords campaign to see what kind of results it generates.
