Google has introduced a few new features for their AdWords service. These new features include an improved keyword tool and the ability to automatically generate site-related keywords simply by providing a URL.
The new tool is nice-- screenshot can be found below. The "Site-Related Keywords" tab accepts any address and spits out keywords and phrases it thinks you should consider (and even some that you do not want to consider... great for negative keywords!).
It is essential that Google preserves the delicate balance of useful yet powerful. These new features don't make it more difficult to use, yet it gives advertisers better tools to manage their advertising campaigns.
