What do you think(or know) is most affective, having multiple link pyramid(chose pyramid since many people say wheel is risky) or having a big pyramid where each web 2.0 has a pyramid of its own. So basically doing 10 Link pyramid to 10web2.0 and than linking it to main said. Please give your views on which option would be best. Also is it better to do link pyramid(wheel) or just do multiple profile links / coments.
