If you are familiar with the 30 Day Challenge, then you know about the GTrends method of calculating search volume for a keyword on Google. The method works extremely well and even Wordtracker has a free version of it that you can use. The problem is that it is just too time consuming. I found a free tool that automates the process of calculating GTrends for your keywords. You just enter all the keywords into a textbox and then hit a button and off it goes. Then once it is done, you view the results and find which keywords are worth your time and which aren't. This tool has saved me hours of manual work and I have found some hidden gems just because I didn't have to waste my own time doing the research.
