Placements are the locations on the Display Network where your ad appears. Examples include relevant websites and apps that partner with Google to show ads.
Over the coming weeks, the “Placements” column in the Report Editor will show the same data that’s displayed in the “Placements” section of your campaigns and ad groups.
These metrics will only include manually targeted placements. Previously, the “Placement” column in Report Editor included data for automatically targeted placements. So keep in mind that these new placement numbers won’t reflect all the placements where your ads have shown.
To view all placements where an ad has shown use the placement(group) filter in the Report Editor. On your campaigns and ad groups pages, you can use the “Where ads showed” section.
