Multilanguage site and reviews leading to duplicate content
I'm developing a multilanguage website in which all main content will be displayed in different languages.
I also have a possibility for reviews on this website. Reviews will be written in the language of the visitor/reviewer.
a list of review will be on the dutch version on:
a list of review will be on the english version on:
A specific dutch review on the dutch version
The same specific dutch review on the english version
Now this will lead to duplicate content + dutch cotent on the english version of the site en vice versa
Also the lists of reviews will be in different languages aswell.
How should I tackle these duplicate content problems and mixed language problems?
help is much appreciated!
