However, at the end of November the rankings of my websites started dropping quickly and have been on a clear downward spiral since then. The drops have come in several steps and I have lost about 75% of all my traffic, and it may continue to drop even further. I have no algorithm penalties and do not know why my sites are effected.
I see that there are many other websites that have been affected in similar ways, and I am certain it is due to Google algorithm changes. Does anyone have any information about these changes and what is causing the ranking decreases/increases? Does anyone have any information on how to best try to recover the traffic?
