Welcome to the Q&A Forum

Hi, I manage around 13 Clients for SEO and this last two weeks i have been having problems with google keyword ranking some of my clients went down almost 40 positions for some keywords other 15 other stayed the same and some just went down 1 or 5 positions. Somebody know what is happening with google? is it shuffling around positions of people? Any advice or how you do your SEO I'm willing to work together and share experiences and tactics on SEO to people that also share with me in order to build more strategies on this amazing market. Thanks.
