I came across this amazing keyword tool that makes keyword research much more easy.
The site is
Keyword Eye : Visual Keyword Suggestion Tool PPC, SEO, Niche Finder
(Not my site, not an affiliate link)
Just enter your keyword and watch the tool churn out hundreds of keywords that are color coded as green, orange or red depending on competition. You can straightaway locate low competition keywords as they are in green color.
Make sure you use the "Advanced Search" after you have searched for a keyword and choose the match type, country, number of results to display, search volume, negative keywords. The tool also allows you to download results in CSV, Text, Excel format. A google chrome extension is available that allows you to use it right from Chrome browser.
Hope you guys like it. Happy keyword researching.
