Just noticed some new features with the Adwords keyword tool: Looks promising...time to go tinker with it a bit.
I've noticed the tool in general is a lot better than before. It seems to be improving slightly over time. You can actually use the tool for what it was intended for.
Wow! This new keyword tool is pretty awesome. I can't wait to start a new campaign. I think I could easily consume several hundred keywords in one ad group.
This seems much better than the old tool. I have to see if its any better at estimating traffic. The "site-related keywords" tool is rather interesting.
