So as a beginner I start reading link building theory and probably the best tutorial of all is the one of Woodward. Clean and effective, however useless in his own word. GODOVERYOU highlight this and the top dog in "tier link building" niche take note and update their thread, in fact Jacob King make a mistake in the post where he explain the flaw of his tier link building... A question came up to me, the post of GODOVERYOU Code: http://seosunite.com/f2/tiered-link-building-tiered-linking-tutorial-815/ is from August 2012 and the tutorial of Woodward and Jacob King (I pick the top of the 1st page on G) around the same period. My question is since when we know that social bookmark can not be use as a tier ? Since the beginning of link building theory or did a change occur later on their structure ?
