On my site I have 1 page that had good ranking for some KW. I have moved the page and change its location with 301 redirect, soon after that page lost the rank! It is still somewhere in top 10 but before that it was in 1-3 place for some KW. Right now I know it was pretty stupid to do this.. but it is better to know what to do for recovering. So what is the best way? Does it help if simply restore old page location? Or I need to perform more actions?
