What is Line item?
Also called: Ad Manager line item
A line item is a booking in an ad server such as Google Ad Manager that holds what to serve, where, when, at what price and at what priority.
हिंदी में पढ़ेंGoogle Ad Manager stores campaigns in three layers. An order is the deal with an advertiser, holding the advertiser, the salesperson and the trafficker. A line item sits inside the order and holds the promise: start and end dates, goal, rate, targeting, type and priority. Creatives, the ads themselves, are attached to line items.
The line item type sets how it competes. Sponsorship and Standard line items are guaranteed. Price priority, Network and Bulk are remnant types that compete on price at priority 12. House line items fill what is left. Header bidding also relies on line items: in a classic Prebid setup, each price bucket has its own Price priority line item.
When delivery looks wrong, check the line item first, because dates, targeting and goals live there. A typo in the targeting, such as an ad unit path that does not match the page tag, means the line item never sees the impressions it was meant for.
Example
A brand buys 500,000 homepage impressions in December at a $6.00 CPM. The line item holds those dates, the 500,000 goal, the rate and the homepage targeting. Its value is 500,000 × $6.00 ÷ 1,000 = $3,000.
Why it matters to publishers
Almost every serving decision in Ad Manager is made between line items, so reading them correctly is a core ad ops skill.
