I have done a lot of manual back linking for my main site and now have it at the top of the niche I wanted so job done (for a couple of months anyway.) I am developing more sites in my niche to target specific keywords and need to do the back linking all over again. I have seen lots of people advertising backlinking packets, including article writing and submission and all sorts of other things on warrior forum and digital point or whatever its called. but there are so many of them offering different things. Has anyone used such services that they can say were well worth the price and that they would be happy to recommend???
