Google AdWords officially launched their new ad scheduling, enabling advertisers the ability to schedule the appearance of their ads based on both time of day and day of the week. This new feature, which competes with dayparting that Microsoft AdCenter has had since their beta launch, was released worldwide to all advertisers across 40+ languages.
Another feature now allows publishers to specify their own time zone, or the time zone they would like their ads to appear in. The dayparting feature allows advertisers to specify the time period they would like their ads to appear. It is worth noting that the ads are served based on the advertiser specified time zones. So an advertiser on the west cost of the US could schedule ads to appear between 1-3pm PST, but someone on the east coast would see those ads between 4-6pm PST. An advertiser could also chose to schedule their ads to display only during their hours of operation when they would be available for customer support or on the phone.
Dayparting features not only work for keyword targeting but you can also use it for any site targeting campaigns on the AdSense network.
