Once there you should have Beta version link which is new keyword tool.
On first glance it has the new Adwords interface like design which in the beginning could be slightly annoying.
Old keyword research tool:
But the new tool offers some really nice features.
I particularly like the Broad, Phrase, Exact match reporting at the same time. The topics to which your keyword may belong is also useful because a particular keyword may be available in different categories and still relevant.
I have noticed some differences between the two tools in terms of Global traffic. The new tool suggests about 5-10% less global monthly traffic compared to the previous version. It also estimates the CPC slightly less.
I will continue playing with this tool in the next couple of days so stay tuned.
Thanks for reading.
