As users increasingly spend time across a growing number of sites, however, display advertising is becoming more challenging. Last year alone there were 47 million new web sites created*. Contextual targeting can help by automatically showing your ad to users on web pages related to your products on the millions of sites in the Google Display Network (GDN). But building and managing your campaigns can still be time-consuming. So how do you reach your target audience easily and efficiently while meeting your business goals?Today, we’re launching two tools -- the Display Campaign Optimizer and the Contextual Targeting Tool -- to help you maximize your performance on the GDN, while saving you valuable time and resources.Display Campaign Optimizer. This new tool automatically manages targeting and bidding for your Display Network campaigns with the goal of increasing your conversions while meeting your advertising objectives. You simply provide us with your target cost-per-acquisition (CPA), creatives and budget, and the Display Campaign Optimizer goes to work, showing your ads in all the right places, automatically. It monitors your campaign performance and, in real time, adjusts your campaign accordingly. Your campaigns stay optimized, as it “learns” and does more of what’s working and less of what isn’t. For example, Seventh Generation, a company that sells eco-friendly household cleaning, baby care and personal care products, was looking to connect with more “green” consumers across the web and get them to download coupons from their site for use in-store. After implementing the Display Campaign Optimizer, the tool delivered 60% of the coupons downloaded from their site, with a CPA 20% below their target. Further, analysis of our beta testers showed that on average, campaign using Display Campaign Optimizer were likely responsible for almost one-third of the accounts’ total conversion volume with CPAs within 6% of their peer group CPA.**The Display Campaign Optimizer is now available globally for larger campaigns running on the Google Display Network.
