Many of you start each day by asking: What is driving a change in my clicks or cost? What campaigns or ad groups saw the the largest moves? Did any of my recent changes break something?

To help answer these questions, we’ve created the top movers report to show you which campaigns and ad groups have experienced the largest changes in clicks and cost, and highlight changes you made which might have contributed to those moves. Even if your overall account performance metrics appear unchanged, the top movers report will look inside your campaigns to highlight big moves that might have been easily overlooked.

How it works
To view the top movers report, click the Dimensions tab, then View: Top movers. The report compares performance for two consecutive time periods of equal length, and finds the campaigns and ad groups that experienced the largest change between the two periods. You can compare periods of 7, 14, or 28 days, or look at reports generated in the last 90 days.

The report will start by finding up to 10 of the largest moves in clicks or cost and present a summary at the top. If a top mover saw an increase, it goes into the “Top increases” category. If it’s a decrease, it goes into the “top decreases” category. When changes aren’t significant enough to be a top mover, they will roll up into “Other changes.”

The table below will give details for each top mover. When possible, we offer a “possible cause” for the move, like “bids were increased” or “new keywords were added”.

Note that “possible causes” only considers changes made to your account. It won’t tell you, for example, if your competitors have raised their bids or introduced new ads.

Top movers is our latest effort to save you time and money by helping you understand changes in performance.  For additional information about using this new report, visit the AdWords Help Center.
