I think i have been penalised from google from duplicate content on my site . I havent in any way done this deliberatly and cant understand why it has happened . My hosting has just changed thou . For instance my home page reads www.example.com/ but i have to home pages www.example.com/ and www.example.com/78gheksjccle8 . Both read exact same content . My webmaster tools at google has picked this up . How can i get rid of this . As my keywords are bouncing in and out of google on a daily basis for the last few months .
