Hi
I would just like to share my own method of driving traffic.
Result of my organic traffic:

Totally no promotion after Jan. And it just keeps on increasing.
This is what I did:
1) I write a very informative post. I know what my niche is about, so I keep on concentrating on the niche.
2) In my post, I do purposely give some stupid misinformation in order to get people to comment and tell me that I'm wrong. This makes my blog kinda viral when someone laugh at me and tell their friends how stupid I am.
3) I give a gift to my visitors. No subscription required, but just referring to their friends. I use a script for this.
4) I promote through facebook. I make sure my content is consistent and don't jump around. This makes my friends think I am so into the niche that all my posts are about the same thing.
5) When I write my post I make sure my keywords are there. And the normal social bookmarking game with keywords targetted.
Yea..basically, that's about it. Just repeat the sequence. I think the point that got me a lot of traffic is point 3 where I use a script.
Hope you like my tips
