Yesterday my website ranking no.1 for its branded keyword dropped to no.2 (inner page not homepage) and was replaced in the no.1 position by a URL that has cloned/copied my homepage but actually redirects to another website (webcam site). So the no.1 site is actually a 301 redirect. Any idea how or why Google would rank a 301 clone of my website as no.1 and how to fix it? My site is custom built using PHP. Also it seems who ever did this created alot of copies as my site keeps getting replaced by a different 301 URL every few hours.
