I have the typical mod_rewrite rules to make urls prettier
RewriteRule ^most-viewed$ index.php?time=1
RewriteRule ^most-viewed-week$ index.php?time=2
But somehow, Google managed to get the index.php?time= version too, so now, in google search results both results show, the one with the mod_rewrite url, and the "regular" one.
I'm afraid this is bad for seo as this could be considered as "duplicate content".
How can I avoid the "regular" one being indexed, or even better, to make it unaccessible to everyone.
I use PHP if that helps.
