I have a site with quality content that are relevant to thousands of other sites. Many sites already link to my site the natural way but I need more links to make that final jump in the serps. I have acquired many links by sending out mass emails to relevant sites, but not nearly as many as I had hoped for. Now I am considering a new approch. My site is a video site and I am planning to make a DVD with high resolution video and sell it. But more important I will offer the DVD for free in exchange for a link. Do you think people will be more likely to ad a link to there page if I offer this gift in exchange? The DVD unique and highly relevant to there interest. I will also step away from mass emails and focus on high PR sites and write more personal emails. Will it be worth it?
