If you look at my forum: http://www.adminfuel.com You will see that there are not many inbound links. How can I increase this?
build a blog farm, and use autoblogging to add hundreds of thousands of links over the next year or so. bloggerhigh has a free ebook about it. Or search the forum for link building strategies.
there are many ways to build backlinks and lot of them are free as well. below are some free ways you can build backlinks: directory submission article submission forum posting with sig dofollow blog commenting social pages like squidoo, hubpages, qassia press release social bookmarking this will keep you busy for a while
participate in the forum and do posting and also replay to the good post. Also submit it to diff directories( not give enough result for free dir , pyed preffer)
