Learn about expanded inventory
The "Expanded inventory" setting allows you to choose to receive bid requests from inventory that may otherwise be blocked.
By default, the "Expanded inventory" setting is off and expanded inventory is excluded. This means that bid requests are filtered and you may receive fewer of them.
When the "Expanded inventory" setting is on, expanded inventory is included and you may receive more bid requests. However, you may receive requests from inventory such as inventory with no content, more ads than content, and content that encourages accidental clicks.
