Google may have just put out an algorithm update a couple days ago that seems to have affected webmaster’s keyword rankings. For the most part website keyword rankings have dropped significantly, while some witnessed an increase by about 20%.
This is still in the early stage of development, but with the recent Panda update already being implemented and the upcoming (and terrifying) Penguin update being expected, this change on August 28th could be a number of things.
I’ll keep you updated once I find out more on this.
