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 www.example.com/Review/CODE/0
to www.example.com/Review/CODE/5
.
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?
