Very few, if any, other services like our own will guarantee their services. After all, most websites are ever changing, so its pretty much impossible to guarantee that a backlink will live on forever. So call us crazy, but we actually do guarantee all of our backlinks. What this means is that if within the first 30 days, your link gets removed from the site, turns into a “nofollow” link, or the page rank of the site drops, we will replace the backlink at no charge. The main reason we can promise this is because of our large directory of very high quality backlinks that is always growing with fresh links, so we never over use any one url. This means that none of our links abused or filled with spam. So the links that we post tend to “stick” pretty well. The good news is that if a link “sticks” for the first 30 days, it will usually stay put for a very long time.
