What else i can do in term of one way links, except: forum posting blog commenting directory submission article writing yahoo answers bookmarking hubpages press release
Make sure the BOLDED items are DO FOLLOW and have page rank on the main page. Otherwise, you'd be wasting your time.
Hey man, I think you have missed one of the massive method which drives the huge traffic..... yups..Social bookmarking.....
I agree with the Do Follow aspect, however, just because a page does not have Google page rank, doesn't mean it is a waste of time. You must remember that Google is not the only player on the field and the other search engines don't pay any attention to page rank Also, just because a page does not have page rank today, doesn't mean it won't have page rank tomorrow...all pages start out with "0" PR
"QUALITY CONTENT" You forgot the best way to get quality one way link, which is "to create quality content". Many people will link to you by themselves, happily if you have unique quality content.
Also, blog writing... Create account on some of the social networks, like Wordpress.com, Blogger.com and link back to your pages.... Just don't be too spammy or you will get banned....
