There is now a free version of Keyword Discovery

http://www.keyworddiscovery.com/search.html

I'm testing it out to see how it compares with the full version.

ha. Saw this article is really good, you write make sense very much.

A great free way to actually check out keywords are on freekeywords.wordtracker.com. This will tell you how many people per day is searching for a particular keyword or phrase. A really good way to track this is compare the info you find in freekeywords.wordtracker.com with the info you find in g trends(google trends). Google trends lets you know which region, city and language is dominant with that keyword. I would really suggest going to majorleaguewealth.com which will link you to online marketing techniques that are great and thirtydaychallenge
