I'm guessing this may have been brought out there before, but maybe not. I use a killer one-way link-building service to promote many of my mini-niche sites. It's a network and you have to participate in order to get the benefit unless you want to pay a fair amount of cash. The service is found at hxxp://www.LinkBuildingSolutions.com It's pretty innovative in that you can set it up to mix and match Directory Style links and In-Context style links. It supports multiple versions of your favorite anchor text and you can point links either at your homepage or "deep link" them to subpages for relevancy and to look natural. The only downsides that I can think of is that the links are obviously pretty low value. While your anchor text is there, the pages these links show up on are not High-PR and they don't directly relate to any niche. Also, it was a bit tricky to setup the first time (it's easy now) and it only supports 300 links....so if you are looking for thousands you won't get them all from this one source.... ...but then again you new better than to rely on one source for links anyway, right?
