I would like you SEO experts will tell, the way I am doing is it right or wrong and WHAT else I have to do further to get good rank and improve my position in search engine result page.

2. Forums
3. Article Submission.
4. Yahoo, google, Msn Groups
5. We also having good shopping reviews from customer’s everyday.

6. Affiliate programmes
