Bid on viewable impressions using viewable CPM
If you'd like to pay only for ad impressions measured as viewable, you can with viewable CPM (cost-per-thousand impressions). An ad is counted as 'viewable' when 50 percent of your ad shows on screen for 1 second or longer for Display ads, or plays continuously for 2 seconds or longer for video ads. You can select viewable CPM as a bid strategy when you choose CPM bidding for your 'Display Network only' campaign.
How it works
With viewable CPM, you bid on 1,000 viewable impressions and pay for impressions that are measured as viewable. An ad is counted as 'viewable' when 50 percent of your ad shows on screen for one second or longer for Display ads and two seconds or longer for Video ads. Viewable CPM lets you bid on the actual value of your ad appearing in a viewable position on a given placement. Bear in mind that using a higher vCPM bid than your CPM bid is usually more effective for winning these more valuable types of impression. This can help keep your bids competitive and continue to meet your daily budget. Learn more about viewable CPM.
