i have a blog that i write posts on and don't worry about targeting a keyword in particular. on thos posts i get a lot of traffic. when i try to target a keyword i dont get much traffic for that post. why do you think that is? seems kind of counter intuitive right? but its happening on my blog!
Check out the competition of your keywords you want to target for and those keywords which bring traffic.... You will get the answer..... Low Competition Keywords Usually bring good traffic.....
