Hello everybody, I would like to ask you a question, I spent three weeks time to optimize the word "iPad cases" , the word stay in the home in Google only two days, and now it is back to the second page. You could look Google I want to rank it to the first page again, as well as iPad case, iPhone 4 case and iPhone 4 cases. I hope that they could stay the first page forever, how can I do? who can give me a good suggestion, thank you very much!!!!
