According to the Google Adwords official blog, they launched two new tools. The Display Campaign Optimizer and the Contextual Targeting Tool. These new tools are to help advertisers get more out of their display network advertisements.
The Display Campaign Optimizer helps in managing the targeting and bidding in the display network campaigns. To use the Display Campaign Optimizer though, your campaign needs to have Conversion Optimizer set up and Target CPA bidding enabled. As of the moment though, DCO is only available to a small group of qualified advertisers, but it will become available to more advertisers over the coming months.
Just like the DCO, the Contextual Targeting Tool is only available to a select few advertisers but will also be available to all advertisers in the coming months. This toll helps advertisers build a tightly themed keyword list for the Display Network campaigns. This tool makes the campaign more effective, while assisting the advertisers to do job of segmenting easier.
