Out of interest how does everyone else go about building one way links? Link exchanges are easier, but as everyone has correctly highlighted carry far less weight.
I tend to submit articles, add sites to directories (not convinced this is particularly worthwhile anymore), blog etc... However this is perhaps harder when working on a clients behalf as I may not be an expert in their market and therefore artcile writing or blogging is not necessarily viable.
I'd be interested to hear everyones thoughts.
