you must be getting good traffic because of good content. Its a very generic keyword with huge competition; not something easy to crank in.
Yeah!! You have some good content there. But, your traffic isn't too high according to alexa. Can you share how many UV you are getting per day?
I see that all of your articles are copy and paste from numerous sites and blogs with small changes. How is Google about that blogs that have copy and paste posts? Is your traffic organic or only get it from referring sites? How many time did you spent on promoting site? THANKS!
