Google AdWords clients are now offered a new keyword suggestion tool though their AdWords account. They've added some nice comparison tweaks to make the updated tool more user friendly and efficient.

The tool allows users to sort results by popularity, cost, and history. It helps build keyword lists, downloadable in .csv, and helps generate lists through automatic variation of keywords with the keyword variation tab.
