For 10 years we have been ranking top 5 in all major keywords for our site. We are now experiencing a 50% + drop, with the keywords that mach our site name disappearing completely. I am now looking at having to lay off staff just to keep afloat. Sadly, sites that 'break the rules' duplicate content, repetition of keywords in description, etc,etc seem to have weathered the storm just fine. Thank you for listening, I look forward to seem the algorithm tweaked, to keep us honest businesses and their employees alive.
