Here we go  again. A lot of website owners still having difficulties to restore from  the latest penguin upgrade and He Cutts said that there will be some  significant changes in the next penguin upgrade which many website  owners may not like. I think this is getting too much. But He Cutt  verified that all the actions taken by search engines is to create web  looking elegant. Here is what He Cutts said in Aug 15At SES San  Francisco during the "Matt Cutts keynote"
"Hey Robert,  I wasn't saying that individuals required to far too pressure out about  the next Penguin upgrade, but I'm satisfied to provide more  information. I was providing perspective on the point that most  individuals were asking me when the next Penguin upgrade would occur, as  if they predicted Penguin up-dates to occur from month to month and as  if Penguin would only include information refreshes.If you keep  in mind, in the beginning of Panda, it took several several weeks for us  to iterate on the criteria, and the Panda effect maintained to be  somewhat bigger (e.g. the Apr 2011 upgrade integrated new alerts like  websites that customers block). Later on, the Panda up-dates had less  effect eventually as we stable the signals/algorithm and Panda shifted  nearer to near-monthly up-dates. Furthermore, we're still in the  beginning of Penguin where the technicians are including new alerts and  iterating to enhance the criteria. Because of that, anticipate that the  next few Penguin up-dates will take more time, integrate extra alerts,  and consequently will have more recognizable effect. It's not the  situation that individuals should just anticipate information refreshes  for Penguin quite yet."
To be  sincere, I am very much concerned what type of penalties for the website  owners are holding out in the next upgrade and what type of SEO  techniques will be efficient after it. Time will tell us. Allows delay  and observe. 2013, By: Seo Master
