What is duplicate content and how can I avoid being penalized for it on my site?
What I would like to do is the following:
I have a website at
http://dev.upcoming-djs.com which display a music chart.
And displays a music player at the right side.
I would like to make an URL like:
Which points to the same page only with the track loaded in the player at the right side.
If I understand correctly it isn't good (SEO-wise) to point different URLs to the same page (with same content).
Is this true? And if so is the penalty severe?
