I was recently directed to a great tool for doing keyword research. It uses the overture database and then estimates the monthly searches in Google and MSN (probably from released search percentages).
The best part of it is that it offers keywords that are similar and related and shows you numbers for those as well. This save you a lot of time digging through overture, and estimating all the numbers yourself in a spreadsheet (or am I the only one that does that).
They also supply quicklinks for every single option you could think of:
Overture Bid Price
Google, Yahoo, and MSN Search results
Yahoo! Suggest
Digital Point Wordtracker
Nichebot
Google Trends
AdWords Google Traffic Estimator
Google Suggest
Google Synonym
AdWords Keyword Tool
This puts some of the best market research tools all on the same page! You can use all of the tools, or none of the tools.
