Ok, First off your website is down. You should get a different host more people will come back and use your website more if it is always up.
I have found twitter to be an excellent way to gain targeted traffic. It is relatively easy to build a large following of people interested in your niche, but be sure not to spam. Spend some time building relationships and making worthwhile tweets and the traffic will come.
unique content & at the same time some link building can differ a lot. It is the easy way from where you can derive traffic easily. Facebook is another option for deriving traffic
