Google released a whitepaper titled "CPA Performance Trends on the Google Content Network." The whitepaper has the following findings, all very positive about how Google AdSense performs:

1. Ads on the Google Content Network are likely to be as cost-effective - or even more cost-effective - than ads on the search network.
   • The median advertiser has a content CPA that's about 2% lower than their search CPA.
2. The Content Network drives a significant share of total conversions.
   • The Content Network drives nearly 20% of total conversions for the median advertiser.
3. Conversion rates are higher for advertisers who used either of two AdWords campaign management controls: the Conversion Optimizer and site exclusion.
