I have recently added mod rewrite to my site (yesterday) and I need to know if I need to redirect all previous urls to the new rewritten urls.
before, my urls looked like this:
domain.com/index.php?page=whateverpage&any=vars
Now, my urls look like
domain.com/whateverpage.html
domain.com/whateverpage.html?any=vars
So I have changed all links and url in my pages to go to the new urls. Google is already picking up these new urls. However, I just want to know this:
1. Is there any penalization? Maybe they will think the new urls are duplicate content.
2. Do I need to add a redirect mod rewrite? To forward anyone coming from old urls to the new ones? Which by the way, both old and new urls work. So I can still access old urls.
I'd appreciate any input. Thank you!
