I have PHP site and I want to make the URL's more SEO friendly. If I was to implement my .htaccess file with the mod rewrite, should I first ask the SE's to remove my PHP URLs? What I am worried about is getting my hands smacked by the search engines for duplicate content - especially Google. I've heard that sites have been put into a filter / sandbox effect in Google due to the number of new pages being indexed in a short period of time. Any advice would be appreciated. Darren
