Hello everyone,this is Doris. Last month one of my site has been penalized(-30).That is not a good news! But i want to tell u guys is: 2 weeks ago the site had a strange phenomenon: the access IP decrease half every day(eg: today 300,tomorow would be 150,the day after tomorow change to 75,just the things like that). But the rank act normal. Now the new site looks like repeat the same thing. I am very worried about it. Who happend to has the same experience? Any suggestion is appreciated.
