Two URLs pointing to almost the same content
If I have a page, that has this URL:
example.com/category/something/
but can also be accessed through these URLs:
example.com/category/something/1
example.com/category/something/2
example.com/category/something/3
where the last number is used as an image-index to display a certain image on the page. So the content of the pages is the same, just with one image changed.
How do I avoid google indexing the versions with /number
at the end, so it only shows up once in searches - and is not considered duplicate content?
Is it enough to put a rel="nofollow"
on links to the /number
links?
