This is a great application for the avid adwords pro. If you’re just getting off the ground it is also very friendly. They regularly update the software and it works fast for those of us on broadband and if you’re not then this is not something you would use just yet. Lets face it though, if you’re marketing on the internet, you should be on broadband to function properly.
Keyword Elite also known as KE has many other functions as well as the identifying niches that would be ripe for new products and services. I use it every time I start a new Adwords campaign.
Rating = Preferred (especially for adwords)
