As you know, Google stepped up the invites to this beta interface last week. Google told me that last week about 20-30% had access to this beta interface, but as of today, Google is rolling it out to all of their publishers. You won't have to use it, if you don't want to - the old interface is still there, but you might want to.
Why? Google said:
- More insights. We've built in simple, graphical reporting and more options for you to easily slice and dice your data, so you can see at a glance what ads are working and which are not, and adjust your strategies accordingly.
- More control. We've made our ad controls richer and simpler to use, so you can better control which ads and advertisers you want to appear on your sites.
- More efficiency. It's now much easier to quickly see earnings and payment information, to run reports, to find relevant features and help, and to make account changes. Our engineers have spent countless hours making sure that the interface is stable and blazing fast. We’ve also spent many hours in our usability labs with publishers, focused on making the interface easy to learn and use for all types of publishers.
I've personally been in this beta for over a year and I like the new interface. There were bugs throughout the year, but is has improved and improved.
