Are duplicate content allowed in Google

There is a popular myth about duplicate content, basically saying that Google penalizes sites for having duplicate content. Well, it is just a non-proof myth that now has been cleared up by Greg Gothaus of the Search Quality Team in Google from his blog post on Google Webmaster Central Blog along with a 15 minute video and presentation slide.

In short, the truth is that this not the case. Google won’t penalize sites for having duplicate content. However, that’s also not saying that duplicate content can’t have a negative impact on your rankings. There are actually a lot more covered in his video, so I highly suggest you take your time watching it through.
