As a webmaster, you may have been concerned about your RSS/Atom feeds crowding out their associated HTML pages in Google's search results. By serving feeds, we could cause a poor user experience:
- Feeds increase the likelihood that users see duplicate search results.
- Users clicking on a feed may miss valuable content available only in the HTML page.
To address these concerns, we prevent feeds from being returned in Google's search results, with
the exception of podcasts (feeds with multimedia enclosures). We continue to allow podcasts,
because we noticed a significant number of them are standalone documents (that is, no HTML page
has the same content) or they have more complete item descriptions than the associated HTML page.
However, if, as a webmaster, you'd like your podcasts to be excluded from Google's search results
(for example, if you have a vlog, its feed is probably a podcast), you can use
Yahoo's spec for noindex feeds.
If you use FeedBurner, making your
noindex is as simple as checking a box ("Noindex" under the "Publicize" tab).
We're aware that there are a few non-podcast feeds out there with no associated HTML pages, and thus removing these feeds for now from the search results might be less than ideal. We remain open to other feedback on how to improve the handling of feeds, and especially welcome your comments and questions in the Crawling, Indexing and Ranking subtopic of our Webmaster Help Group.
