Clearly a simple and effective way to outrank your competition is to reverse engineer their backlinks.
There are tools such as Market Samurai and Yahoo Explorer to see the backlinks...
But, in your experience, what's the best strategy to reverse engineer? For example, it's easy to reverse engineer blog comments or forum posts, but what about backlinks that are hard coded?
Is it literally a case of contacting the webmaster and asking for a link?
Any thoughts massively appreciated from Warriors that have 'seen it, got the tshirt'!
