What is Price priority line item?
Also called: Price priority, price-priority line item
A Price priority line item is a non-guaranteed Google Ad Manager line item at priority 12 that competes on price. Prebid setups use it.
हिंदी में पढ़ेंPrice priority is one of Ad Manager’s remnant line item types. It runs at priority 12, is not guaranteed, and competes on its rate against other priority 12 demand, including Network and Bulk line items, AdSense and Ad Exchange. The highest net CPM wins.
This is the type Prebid’s setup guide uses for header bidding. Each line item targets one price bucket key-value, such as hb_pb=2.80, with a rate equal to that bucket. When Prebid sends a bid in that bucket, the matching line item competes on price inside Ad Manager. Medium granularity needs 201 such line items per set.
Through dynamic allocation, Ad Exchange competes with the highest-priced remnant line item that has not reached its goal. If a Price priority line item has a value CPM, Ad Manager uses that instead of its rate. Pricing rules can also apply: a remnant line item needs a rate at or above the floor to compete.
Example
Prebid sends a bid in the 2.10 bucket. A Price priority line item targeting hb_pb=2.10, with a $2.10 rate, competes against a $1.95 AdX bid and wins.
Why it matters to publishers
In a classic Prebid setup, header bidding revenue flows through Price priority line items, so their rates and targeting must match your price buckets exactly.
