Apple has added a new section to its iTunes Connect developer portal, iAd Workbench
. The tool lets app developers promoting their titles via iAd to exercise more control over ads and campaign budgets. The minimum spend for such campaigns is now just $50, and developers can ask to pay on a cost-per-acquisition (CPA) or cost-per-click (CPC) basis. Apple provides estimates for the reach of a given campaign, including statistics for impressions, taps, and downloads.
More significantly developers can customize campaigns to target preferred audiences, based on criteria like location, previous iTunes/App Store downloads, and so forth. One given
example is advertising for a to-do list app, which a developer could choose to aim only at people who have a habit of downloading productivity and utility apps. Ads can also be set to appear only in certain categories of apps.
