Duplicated Pages and Forums

[waltergah]

Does duplicate content hurt that particular duplicated content, or the entire site? There are some parts of my site that I don’t care about getting high rankings on search engines. For example, I have a forum and there are certain links that only logged in people can see. If you aren’t logged in, they will take you to a page where it tells u to log in. google, obviously not logged in, interprets this as lots and lots of the same duplicated page. Should I just leave it alone cause I dont care if those pages makes it to search engines. Will it not hurt the entire site? For example, can my homepage search rankings decrase?

That leads to my next question. What is the best way to optimize a forum? Whenever someone posts a new post, it seems another url for the same forum thread is created..... which is obviously duplicated….in other words, if like 20 people post on a thread, i believe my site adds 20 urls for that page...anyone know how to fix this?

If you have lots of duplicate pages, you can get hit by Panda, which tends to be a site-wide penalty.

However, I would look for ways to correct this rather than just ignore the pages as Google tells everyone not to duplicate content.
