CPM
Cost per 1,000 impressions (CPM) is a metric that represents how much money advertisers are spending to show ads on YouTube. You’ll see a few different CPM metrics in YouTube Analytics:
CPM: The cost an advertiser pays for 1,000 ad impressions. An ad impression is counted anytime an ad is displayed.
Playback-based CPM: The cost an advertiser pays for 1,000 video playbacks where an ad is displayed.
What’s the difference between CPM and playback-based CPM?
Videos on YouTube can have more than one ad. CPM focuses on the advertiser cost for ad impressions. Playback-based CPM focuses on the advertiser cost for video playbacks that include one or more ads. Your playback-based CPM is often higher than your CPM.
For example, say your video is viewed 5,000 times. 1,000 views included one ad and 500 other views included two ads, for a total of 1,500 views with ads. This instance means there were 2,000 individual ad impressions, but only 1,500 monetized playbacks.
Let’s say the advertiser paid $7 total. The video’s cost per impression would equal the $7 advertiser cost divided by the 2,000 ad impressions, or, $0.0035. The CPM, or cost per 1000 impressions, would then equal $0.0035 times 1,000, or, $3.50. The playback-based CPM would equal $7 divided by the 1,500 monetized playbacks, times 1,000, or $4.67.
