I am using a theme that automatically adds hatom-entry, hatom-feed classes on my WordPress blog.

I read that such tags/classes should be used for syndicated content.

Anyway, then I ran a Rich Snippet Tool, which threw a "HAtomfeed" error. So I removed a "hfeed" div tag.

Now, should I be concerned? Can this cause any problems? I still have a couple of these classes (listed below), and I just hope they do not effect my site's ranking.

For now, these are the tags the Rich Snippet Tool has detected:

hatom-feed

hatom-entry:

entry-title:

entry-content:

published:

author:

fn:

person-name:

url:

Appreciate your help!
