I currently have a url structure on one of my sites that uses a mod rewrite to change dynamic mysql urls from: abc.com/page.php?id=1 to a more seo friendly abc.com/page/search-friendly-info-1 My question is, I have another url that will also use a mod rewrite that will go to an entirely different page but use some of the same link info that I've used in the first url. It will look like this. abc.com/newpage.php?id=1 to a more friendly abc.com/new-page/search-friendly-info-1 The phrase "search-friendly-info-1" is identical in both urls but the directory has changed since they will be 2 unique pages, the pages have some similar info but the new page will be even more targeted and a longer tail type of page. Will this cause any confusion in Google's eyes since those pages with the first url structure have already been indexed? Will they see them as 2 unique urls even though the last part of the info is identical? Thanks for your help.
