What is Value CPM?
Also called: value CPM
Value CPM is an estimated CPM you set on a Google Ad Manager line item. Remnant line items use it instead of their rate to compete with AdX.
हिंदी में पढ़ेंValue CPM is an amount you set on a non-guaranteed line item to help Google Ad Manager estimate what it is worth. Ad Manager uses it in revenue calculations, and it also changes how the line item competes for impressions.
For remnant line items, such as Price priority, Network and Bulk at priority 12, Ad Manager uses the value CPM instead of the rate when competing in dynamic allocation and First Look. So the line item faces Ad Exchange or AdSense at the value you set, and the higher CPM serves.
Value CPM is useful when a line item’s booked rate does not reflect what it really earns. It only helps if it is accurate. Set it too high and the line item beats AdX bids that would have paid you more. Set it too low and it loses impressions it should have won. Base it on recent revenue data and review it when that data changes.
Example
A Network line item has a $0.50 rate but really earns about $1.80 CPM, so you give it a $1.80 value CPM. AdX bids $1.60, and the line item's $1.80 value CPM wins. Without it, the $0.50 rate would lose to AdX.
Why it matters to publishers
A wrong value CPM quietly hands impressions to the lower-paying source. Checking it against real earnings keeps dynamic allocation fair.
