Line item type that is commonly used to traffic your ad networks. Network line items:
- Can allocate a specific percentage of your remaining impressions that the line item should fulfill.
- Can be set to have an unlimited end date.
- Aren't included in forecast results.
- Are eligible to compete directly with AdSense and Ad Exchange.
How network line items compete with other indirectly-sold line items
Ad Manager ranks all eligible remnant line items by their CPM rate (or value CPM , if defined) to choose the highest value remnant line item.
For network line items, their weight determines how often they compete in the ranking against other remnant line items. For example, if a network line item has 100% weight, it always competes against other remnant line items based on its rate. If a network line item has 50% weight, it competes against other remnant line items about half of the time.
If AdSense or Ad Exchange has a line item with a higher CPM than the one selected by Google Ad Manager, regardless of the type, Ad Manager serves the AdSense or Ad Exchange line item. Even though a network line item may be set to 100% of impressions, for example, it could wind up not delivering if it's always beaten by another non-guaranteed line item, AdSense or Ad Exchange.
