AOL’s Platform-A today announced the launch of its spot marketplace, the industry’s largest online spot advertising market for display advertising.

The spot marketplace will let advertisers bid on select unsold inventory across the entire Platform-A network on a cost-per-thousand (CPM) or on a pure performance basis (cost-per-click or cost-per-action). The Platform-A network includes advertising inventory on all AOL owned-and-operated sites – such as AOL News, Sports, Money & Finance, Moviefone and MapQuest – along with the thousands of publisher sites in the Advertising.com network. Platform-A is AOL’s advertising business.

“I’m thrilled to introduce Platform-A’s spot marketplace as a complementary solution that lets advertisers further extend their reach across the Platform-A network,” said Lynda Clarizio, President of Platform-A. “With this product, Platform-A is providing marketers with a spot marketplace that is scalable, drives results, and extends advertising brand value.”

The spot marketplace complements other Platform-A advertising solutions, such as branded content integration and editorial sponsorships. With just one insertion order, advertisers can run a spot market display campaign across the entire Platform-A network with one tracking, reporting and delivery system. The backbone of the spot marketplace will be Advertising.com’s award-winning AdLearn technology that optimizes and targets the delivery of advertising to meet advertisers’ objectives.

The spot marketplace further supports the mission of Platform-A by offering comprehensive solutions for advertisers and publishers across multi-digital channels. Earlier this month, Platform-A introduced PubAccess, a Web-based, self-service interface for publishers to join the Advertising.com network and easily manage the advertisements displayed on their sites.
