I'm not sure whether this has already been discussed here. If yes, please give me the link. So here it is. As we all know, web 2.0 link wheels as very handy for link building, the back hat way. But if I use forums rather than web 2.0 properties, its it good? Of course they can't be as good, but still, will it be any good? So say, I register at high PR ******** forums and use my profile page(signature and homepage box) and use them to build link wheel, putting the previous profiles link on the current one and so on, any good? Need some expert advice here. Regards.
