I am a web developer at an IT consulting firm: http://bit.ly/gclCet

We have 100% unique content all focused on the information technology industry and we leverage many different subject matter experts in the production of our content in order to ensure it adds value not only our website but the web at large.

However our generic keyphrase traffic was down -68% in the Feb 24th - March 7th period in comparison to the Feb 12th - Feb 23rd period. Generic keyphrase traffic had been on the rise over the past several months as we steadily produced more valuable content and took no special efforts to promote it.

I have noticed that rankings have dropped significantly for many of the keyphrases that were driving this traffic prior to the update. For example we had a case study (http://bit.ly/h6fDmL) discussing a messaging gateway we developed for a client that ranked #1 in our region for the keyphrase "messaging gateway" but can now only be found around position #393. A similarly dramatic drop occurred for other regionally targeted phrases like "e-commerce", "it consulting firm", "it consulting services", "it integration", "it staff augmentation", "network management", "network security", "software architect", and around 40 other phrases.

I know it is a small sample size, but the correlation can simply not be ignored, does anyone at google with knowledge of the changes to algorithm have any insight as to why we were affected and more importantly what we can do to rectify the situation?
