Here are some tools that I have pulled from this thread As well as doing a simple SE search. I use a few of them if one is slow, times out et cetera. http://www.webceo.com/keywords.htm?source=Bestsellers&kwd=keyword+popularity http://inventory.overture.com/ http://www.digitalpoint.com/tools/suggestion/ http://www.keyworddiscovery.com/search.html http://www.wordtracker.com/free-trial.html I use overture and keyworddiscovery as well as DPs.
I use google Adwords Keyword tool and it gives very accurate results!.The DP keyword tool is good too.
I haver used this tool, http://www.123promotion.co.uk/ppc/index.php for many years and find it to be by far the best!
it seems keyword discovery is pretty good. but i don't really understand the data. what does it base it's data on? in other words, which search engines, and are the results that it gives based on a 1-year estimate or several years? thanks.
wordtracker, heres the link http:// freekeywords . wordtracker . com/ -- remove the spaces cant post the links yet!!
I'm using worldtracker.com, but for me one of the best one was overture, but it is not longer right now... Best, Jakom
