To address ‘customized reports’ issues in Report Center, Google integrated advanced performance data into campaign management. Now, instead of running a placement performance report, you can manage your automatic placements on Networks tab. Rather than run a search query report, you can use "See search terms" option on Keywords tab to see which searches’re bringing up your ads. And if you prefer to look at your reports in a spreadsheet program, you now’ve option to download nearly every table in your account (look under the "More actions..." menu above each table). You can also use new segmentation functions to slice and dice your data directly within campaign management. Click on "Filter and views" menu above your statistics, then choose "Segment by" option to see different levels of detail available for display. The segmentation options available to you differ depending on whether you're looking at keywords, ad groups or campaigns.
