My site uses mod_rewrite to make friendly URL's, which is supposed to make finding our content easier for both search engines bots and humans alike.
However, my Google Webmaster Tools is now alerting me of supposed duplicate content in titles and meta descriptions because of this. Some pages appear to be indexed two or three times because of dynamic URL re-writing.
Is this something I should worry about? I always hear that Google frowns heavily on duplicate content. But what if something LOOKS like duplicate content but really is not? Is there an obvious solution I don't know about?
