Would like to hear your input on this one.. I have a large Wordpress website and I have set my Category and Tag Archives of my blog to noindex and have not included them in my Sitemap. Reason for this is that the Archives not really add anything from a user perspective and that there is a risk of duplicate content. They basically are just overviews of articles written on a specific subject. While reading some SEO websites and doing some research on other websites I found that some sites actually include their Tag and Category archives in the search engines and that others simply include them in their Wordpress sitemap but have them set as NOINDEX. What do you guys do?
