Read This : Mixed Messages From Google Hope it helps Check your webmasters tool and analytics to get more stats
We have been this discussing this for the last 2 weeks in some other thread. Also happened too me at October 28th: 4 Authority sites older than 2-3 years, #1 in some major keywords for over 1 year, all gone to 5th page. All of them. Right now at top 10 just sheeet results: WP/Blogger/Mfa... you name it. Even Yellow pages ranks #1. Too bad to be true. Anyway, since there is nothing we can do besides work on the sites, that's what i'm doing as usual: providing new relevant + unique content.
Your site is barely a year old... I would consider that pretty "new" in regards to having stable search traffic. Stable organic traffic can take up to 4-5 years to achieve. Until then, you are competing with tons of other "new" sites in an effort to stand out...
Thanks for the url. This is exactly what happened to me and other people. And this has nothing to do with new sites. Both new and older sites get this "slap" more often than we think. Checking my Webmasters tool again... Edit: My Webmasters tool console shows everything normal.
I have also been hit. I'm kinda freaking out because this has been a top site of mine. Webmaster Tools also said that pages aren't included in Google's index. Anyone have the same problem or have I been banned?
I had this happen to one of my sites. The problem was that a user had done some SQL Injection on my site. Google found it and penalized my site. I had to submit a resolution asking for the penalty to be removed.
