Welcome to the Q&A Forum

This shouldn't be too difficult a change then. We only have around 20 articles that were hit by this particular issue. Thanks for the response, and everyone was very helpful.

We have articles written for how to setup pop3 and imap. The topics are technically different but the settings within those are very similar and thus the inital content was similar. SEOMoz reports these pages as duplicate content. It's not optimal for our users to have them merged into one page. What is the best way to handle similar content, while not getting tagged for duplicate content?
