Microsoft adCenter Excel Plugin
There is a new keyword tool out there better than the usual overture and our traffic estimator tool.
It is an excel 2007 plugin that does:
Keyword Expansion – we have included 3 different expansion algorithms: campaign association, fast contained, and category simulation
Keyword Search Volume Historical and Forecast – we have included daily and monthly keyword traffic data, including forecasting
Keyword Buzz – you can find buzz keywords in our 300+ verticals
Keyword Demographic analysis
Keyword Geographic analysis
Keyword Monetization – you can find all monetization information (CPC, CTR, etc.) for your keyword list
I definitely recommend giving it a try. You’ll need Excel 2007 to run it. The best part - it’s free.
