Death of The Yahoo / Overture Keyword Suggestion Tool
Andy Beal reported that Yahoo Search Marketing is no longer supporting it’s keyword tool, known to many Internet marketers still as the Overture Keyword Suggestion Tool.
The tools will be replaced by Yahoo’s new Sponsored Search tool, which I think is only available to active advertisers. However, Yahoo will soon update the keyword data to include search results beginning January 2007, and they will continue to update it from time-to-time. I doubt, however, that the tool will continue to remain an accurate gauge for keyword-based marketing research.
It other words, you may be actually looking at outdated data is you’re still using the Keyword Suggestion tool. A few better alternatives:
- Keyword Elite research tool - I uses this. Comes with all the analysis functions you’ll ever need, highly recommended
- Word Tracker - Use by most people, but only give you raw keyword data
- Keyword Discovery
Take note that all other tools based solely on the Keyword Suggestion tool will also be less effective.

I've gotta say "BIG Thank You" for creating 
Niceto share all the keyword search tools. Do you use Google Keyword search tool? Is that good?
Honestly, Overture had big flaws anyway
When my site ranked #4 for secure email I thought I got a big jump (2000 users more), but nothing happened!
Use Google’s Adwords Tool instead. They dont give you numbers but an overall estimate like “Low, Medium High”
