The day that many of us were expecting has finally come. The Overture keyword research tool has been deactivated.
So where does that leave the folks who relied on this keyword research data?
Well there are still a few free tools around you can access if you are on a very tight budget.
They are pretty limited in scope, but still of some use. For example:
Google's Keyword Tool
Trellian's Keyword Discovery Tool
Miva's Keyword Generator
7Search's Advertiser Tools
Wordtracker's Keywords Tool
Unfortunately, if you are already making a few dollars online (or plan to), I wouldn't recommend these. The data they provide is simply not good enough to base a professional online business upon.
If you haven't already, you should seriously be looking at using a more robust and accurate keyword research tool now.
