eBay and Amazon announced they were adding new features to their ad platforms, which allow third-party merchants to run ads on the marketplaces.

eBay is rolling out a new look and new features to its AdCommerce advertising platform on September 23, 2009, including a new home page, a new ad creation tool called Ad Wizard, new dashboards, and improved reporting. Advertisers will be able to create reports by day, by campaign, by ad, and by keyword and will be able to view two metrics on the same graph to compare results. In addition, eBay is testing Return on Investment (ROI) metrics that will allow advertisers to track purchases and bids on eBay that directly result from ad clicks.

Amazon.com also announced new features on its Product Ads cost-per-click ad program. The company expanded the range of price values it is able to accept from Yahoo Store Sync and Yahoo Store file uploads, added a Manufacturer Part Number attribute, and expanded the unit of measurements it is able to accept for the Shipping Weight attribute.
