I once wrote two articles explaining what link builders should and more importantly should not do when trying to get a link from a blogger. I still think many link builders should read that because I still get many crappy e-mails. But there are more ways of looking at the do’s and dont’s for link building.
Like for example the poker-angle. Now poker sites simply love their links so this is one way of getting them, making a nice infographic, but it also is some nice information about what you should and should not do as a link builder.
