Straight copying is for douchebags. There are so many intricacies to each campaign that make it profitable, you will never know all the details unless you split test your own variations. No spy tool will ever show you the whole picture and they leave out the most important elements.

The difference in advertising cost between a Quality Score 7 and a Quality Score 9 or 10 is enormous. Account history and campaign performance over time will factor into that. You won't have those benefits until you get the same.

QS 9 pays about 40% less than QS 7.

Do your own work.
