It seems that it is Google's roll-out new features day today. First GSC now a new Ad-Review center.
The layout has changed completely. The ad units are now fully visible, so wide ads such as 724x90 ads are no longer cut-off, so that is good, they are easier to see without require a click. But the square ads are now smaller thus making the text harder to read, so not sure if this was great trade off.
The block icon is now reduced to symbol and once you click on an ad they felt the need to flip the layout so that things that showed in the left side bar are now on the right. Change for change's sake?
The biggest change is that one can longer block an ad based on the destination URL. Fundementally I have an issue with this but I guess practically it isn't a big deal since most of the spammy ads used multiple url's to avoid AdSense filter and being blocked. Ad words accounts can still be blocked but now you can access the list of blocked account, this wasn't possible before. Not sure if this really useful but it doesn't hurt.
I just had a chance to use this once, so I guess after more time working with the new tool I might find some other great features.
I also noticed that my "revenue profile" report is working again after it showing errors for past few month. Who knows maybe we will get the Ad-Balancer back.
