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.
