Well i was surfing the net today as usual, looking for new ways to get some more backlinks for some sites i run and i came accross this great little site.
http://www.freelinksdirect.comSee what they do is you sign up for an account and you tell them the category your site fits into, they generate you some link code to place on your site displaying a few of the other sites in that same category.
Ok sounds good so far, then you wait, as people sign up and join the same category as you there is a chance your site gets picked to be one of the sites they have to link to in that code like what you generated when you signed up.
Ok well the good part is that you link to about 4 sites but the potential for hundreds of sites to get your link over time, you never get linked from any of the sites your linking to so your always getting unique one way links.
On top of that they dont let your site be chosen too often within a short space of time, as any good seo knows, gaining too many backlinks over a short period of time can set up red flags with the search engines so a more natural slow build up of links is much better.
So i suggest you check them out.
