Google's Top Movers report for AdWords advertisers, which originally launched in 2013 is getting an update.
Google quietly announced the update on Google+ saying they've "simplified" the top movers report by making "it easier to find changes across your account and quickly identify ways to improve performance."
Here is a picture of the new top movers report:
Google gave this example of why the report is better:
The summary table at the top now highlights the most important changes in your top movers metrics for the date range you set. Now, you can quickly see total changes across your account. And, you can drill down to see the campaign or ad group that has changed the most for cost, clicks, and conversions.
