Over the next few weeks in the US and UK, we'll be rolling out the ability for advertisers to bid for phone calls -- in addition to bidding for clicks -- when they show Google search ads on computers and tablets.
well the phone numbers in adwords trick will only last so long.... you'll start to get calls but you won't get any clicks, so your ad will seem like it isn't performing then you'll vanish cause of low CTR.
so what if goog does track it? is goog going to give me a goog tracking number? I don't want my customers remembering or saving a goog number that i might or might not have next week.....that I might get charged per call on.
