I found this very usefull tool to increase traffic on your blog.The great thing about this tool is that it is compatible with almost all Blogging Softwares.Once you download and install it you will get a little W icon in the bottom right of your web browser.Click to open it then it will open a menu and all you have to do is enter the subject you'll be writting about and it will give you a list of the keywords that are the most searched for in Google.Words like Google and Youtube generate about 500,000 searches it would be very usefull depending on your subject.This is very usefull for Search Engine Optimisation(SEO).It will optimise your text to a maximum to get the best results ever.To download go to this website http://www.wordtracker.com/academy/5-minute-seo.You will need firefox to use this once you finish downloading you must restart Firefox for the changes to apply.It's an add on.
