I know a lot of you may already know this but I thought of sharing this because recently I just realized the power of this method.
So what is it??
KEYWORD RICH DOMAIN NAMES!!
I have a niche site which is about a year old and it ranked (still does) pretty well for a lot of keywords except one of the main keyword which is pretty competitive...
So I decided to do this experiment and I bought another domain which had the main keyword in it (the keyword the other site couldn't rank for). I threw up a quick wordpress blog on it and added some unique content on it. Then slowly I started building links to it through submission directories etc.
And guess what? In 3 weeks it's ranking 4th for that keyword!
Now I know most of you knew this but just a reminder try this...it works wonders!
