Will RSS feeds cause Google to penalize a blog for duplicate content? Several of the feed sites are listing more than a few sentences of my blog entries and I wondered if it would be best to remove my listings?
What tool are you using to produce your RSS feed? You should be able to limit how much of each entry is provided to the sites that republish it. If they are just republishing a short excerpt followed by a link to the complete content at your site, you shouldn't have an issue.
Duplicate content is generally a filter.. NOT a penalty. In your case it is completely legitimate and U should be fine. More on duplicate content -
