Google has updated web interface for AdWords, and invited a small group of US advertisers to start testing the new interface :We're testing changes to the ways that AdWords advertisers see and manage the data in their accounts. These changes should make it easier to tackle common tasks, like navigating between campaigns and editing keywords across several ad groups. We hope the updates will give advertisers clearer insights into their ad campaigns and simpler ways to act on those insights.
To answer a common question: The updates we're testing won't affect how ads run. Bidding, ranking, Quality Score, and the other key AdWords performance fundamentals are not changing with these updates.”
