I have created my own site and worked on its SEO. It reached the top five ranking in its page rank and is doing well. I am now targeting the top ranking. I would like to know any more methods that are available for the improvement of rankings? I have tried a lot of things but my rank seems to be stuck at its position for now. So are there any other relevant methods other than social bookmarking, article submission, Press releases etc.
Can anyone please help me in this aspect?
