What is duplicate content and how can I avoid being penalized for it on my site?
I've a new website coming up with 1000's of page which will contain some city codes. I'd also like to place city info copied from Wikipedia(as per Creative Commons License).
Now the focus of the pages will be city codes. Wikipedia content will be there only to improve page appearance.
However it can be slapped duplicate content penalty so I should use rel=canonical.
But the main content/focus of site is some city codes and not Wikipedia info per se. Rel=canonical will give impression that whole part of page is duplicated lowering the page seo worth.
What should I do to tackle this duplicate content issue?
