Google this week announced the introduction of sponsorship by daypart or percent of share of voice in programmatic guaranteed (PG) deals, in addition to the cost-per-thousand impression (CPM) deals or the cost per day (CPD) sponsorships.
Publishers are able to set up PGs in Google Ad Manager with a percent of share of voice. This means that a buyer can run ads on a percent of the impressions available throughout the entire day in a specific publisher.
The other option is the sponsorship by daypart where advertisers can run PG ads just on a time frame of the day. Google exemplifies with the Thanksgiving day, where advertisers are now able to reserve impressions available between 6 PM and midnight, for example.
