Hi, I am trying to rank a health related website. This is the url: www.ridpiles.com Domain age is 1 year 6 months. Done Directory submissions Blog Comments + Forum posts Done Social Bookmarks Article submissions (Not much) I have done competitor analysis. All of my competitors are just had links from directories and some link exchanges. They got links from quality sites like Yahoo dir. I know my site is far better than my competitors and has 100% unique content. I have submitted to yahoo directory inclusion, but still no luck i hadn't accepted into it. I am planning to go for a sponsered review but dont know, weather the link will be valuable for that much of money. I was left with Guest Blogging. I see this is the only option for me to build links. But i have a very tough competiton, i must compete with most reputed sites like webmd.com etc, i need to get more good links. But i cant get what other ways to get authoritative links. If Guest blogging is the only option for me, how many posts do i need to do daily? And can someone suggest me good Guest blogging sites? Anyhelp would be appreciated.
