If you are aiming for traffics from Google, the last thing you want to end up is having duplicates of a same content being indexed by Google. They will eventually being treated as supplemental. Feeds is one of the content you don’t want to get indexed as they are duplicates of your original contents. I had this problem numerous times, and it took me a while to figure it out. So I am just listing out few ways you can avoid that (in the context of Wordpress): 1. Add nofollow to Feed Button: Check your feed button, make sure it comes with a rel="nofollow" within the hyper link codes. 2. Add nofollow to Comment Feeds and Trackbacks: If you provide feeds and trackback for single post, you should add rel="nofollow" to them too. Adding these codes varies from themes to themes, but big chance you might find them inside comments.php. 3.Activate NoIndex in Feedburner: If you are using Feedburner, head over to Publicize -> NoIndex and check on Indicate that your feed should not be indexed by search engines. 4. Add Disallow /feed in robots.txt: Add these following into your robots.txt to suggest feed related contents should not be crawled. Disallow: /feed/ Disallow: /*/feed/ Disallow: /*/feed/rss/ This should stop the crawlers from indexing all contents related to feeds. I think thats pretty much it! You guys can add anything that i probably have missed. Cheers
i agree 100%. this will save you from duplicate content penalty and gets your site out from supplemental result.
