How to prevent duplicate content in archives?

[naturalsociety]

My news site has a number of excerpts in the form of archives based on categories that is causing duplicate content problems.

Here's an example with the nutrition archive. The articles here are already posts, so it creates the duplicate content.

Should I nofollow/noindex this category page along with the rest and 2011,2012 archives etc (see archives here)?

Thanks so much for any input!

Install Yoast's Wordpress SEO plugin. Has all the options you're looking for in one easy tab

I'd leave the archive crawlable since you use them in your nav bar. Just make sure to have canonical attributes on my posts. Also, use the "strip catagory base from URL" option - makes it all look a bit cleaner and shortens your URLs

Thanks a lot for the answer, Bob. I'm currently using All in One SEO, do you find that Yoast's is much better overall as well?

Appreciated.

Yeah, the Yoast plugin has more advanced options. It also has a lot less annoying ads in the admin panel

Thanks, Bob. I've begun the switch over -- appreciate the follow-up.
