Allows app developers to spend as little as $50 on iAd campaigns
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.
