Google announced on Google+ that the roll out of the new notification and alerts icon in the Google AdWords advertising console should be live for all soon.
Google said they began rolling out the new design "earlier this month." They said the new approach is "more streamlined" for the notifications and alerts system in AdWords.
Google said it makes it "easier for advertisers to see critical information quickly, and without clutter, prioritize alerts and suggestions, so you can focus on what’s most important in your account, and see all of these messages in a single place, so you always know where to find important notifications - wherever you are in your account."
Here is a fuzzy screen shot of it in action:
Google said that in the past, you may have noticed various styles used to display notifications in your AdWords account, depending on the type of message. Now, your notifications are cleanly available in one place by clicking on the notification bell icon. The most critical alerts are still surfaced to you in a red bar at the top of your account, or with a yellow bubble icon previewing titles of important messages for you.
