I have a product review page that defaults to showing all reviews. On this page I have 5 links which link to showing only the 1, 2, 3, 4 and 5 star ratings.
If I have a product with 1 review which is a 5 star review, the 5 star review link then gets flagged for duplicate content as my URL changes from
But the content doesn't change (as there is only the one review).
My initial thought is to add
no-index to the review page that lists everything and only allow the search engines to index each star rating page individually.
Is this the correct approach?
