Google Update 2010 - Mayday” Update Impacts Long Tail Traffic

Google made between 350 and 550 changes in its organic search algorithms in 2009. This is one of the reasons I recommend that site owners not get too fixated on specific ranking factors. If you tie construction of your site to any one perceived algorithm signal, you’re at the mercy of Google’s constant tweaks. These frequent changes are one reason Google itself downplays algorithm updates. Focus on what Google is trying to accomplish as it refines things (the most relevant, useful results possible for searchers) and you’ll generally avoid too much turbulence in your organic search traffic.
