Reach and frequency buying is an ad-buying tool that lets you purchase ad campaigns in advance whilst having increased control over how many people you reach and how frequently those people see your ads. You can also create multiple versions of an ad campaign and share them with colleagues using the complementary Campaign Planner tool.

Note: Access to the reach and frequency buying type is being rolled out to qualifying advertisers gradually and may not be available to you at this time.
