The metrics used to determine sell-through are unavailable if any "Delivery" dimensions are added to your report.

Metric category	Metric
Total	Total ad requests The sum of all ad requests. It is equal to the sum of "Unfilled impressions" and "Total code served count". For single ads, each request is counted once. For optimized pods: Each ad returned in the pod is counted as an ad request. Your ad opportunity duration is used to calculated the number of ad requests for any unfilled time in the pod. Total fill rate Formula: (# Total impressions) ∕ (# Total ad requests) Total responses served The total responses served to an ad request. Total unmatched ad requests Total requests where no ad was selected. Calculated from the unfilled time for optimized pods.
Ad server	Ad server responses served Ad requests that were filled by Ad Manager ads.
AdSense	AdSense responses served Ad requests that were filled by AdSense ads.
Ad Exchange	Ad Exchange responses served Ad requests that were filled by Ad Exchange ads.

Video Solutions

You can run a sell-through report to specifically understand video fill rate. This report can be used with any video inventory, including display ads, single video ads, and video pods. For optimized pods, it includes total ad requests and unmatched ad requests, calculated from the unfilled time in the pod.

By default, Ad Manager uses 30 seconds as the unfilled duration used to report on unmatched ad requests. For example, using the network default of 30 seconds, an optimized pod with an unfilled duration of 2 minutes will be considered to have 4 unmatched ad requests in reporting.

You can adjust this setting at Admin ❯ Video and audio ❯ Ad opportunity duration.

How video sell-through metrics are calculated

The values for video sell-through metrics are calculated per optimized pod, based on the number of filled ads and the unfilled duration of the pod. Each ad that serves in an optimized pod is counted as an "Ad server responses served" and the "Total unmatched ad requests" are calculated by dividing the unfilled duration of matched requests by a network constant default value of 30 seconds.

See an example

Ads are requested for a 120-second optimized pod
Three ads serve to the optimized pod:
[30 second ad] + [20 second ad] + [20 second ad] = [70 seconds filled]

Calculations

Total unmatched ad requests
[ unfilled duration / "Ad opportunity duration" value ] *
[ 120 - 70 ] / [ 30 ] = 1 unmatched ad request **

Total ad requests
[ total responses served + unmatched ad requests ]
[ 3 + 1 ] = 4 total ad requests

_{* The network-level value set at Admin ❯ Video and audio ❯ Ad opportunity duration. The default 30 seconds is used for this example.

** Only whole values are counted; any remainder is not reported.}
