Automatic Experiments for Adsense
Google is expanding its collection of optimization tools with the introduction of Automatic Experiments for Adsense publishers.
Enabling the feature will allow Google to run automatic experiments on a small portion of a publishers traffic and provide data about which ads perform best on a website. The data could prove to be rather useful information for those looking to optimize their ad inventory and increase revenue and user engagement.
The opportunities generated from these experiments will appear in the “Opportunities” page on the Optimization tab within publishers AdSense account and will be labelled "verified by experiment.”
