Possible Duplicate:
Two URLs pointing to almost the same content

If I have a page, that has this url:

  • domain.com/category/something/

but can also be accessed through these urls:

  • domain.com/category/something/1
  • domain.com/category/something/2
  • domain.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 are 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?

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

you have to define a canonical tag that points to:


so that even if google looks at the other urls you mentioned, it definitely know that they belong to the main-page defined in the canonical tag.

Here is the official google blog post and the explanation for the canonical url.

BTW, putting a rel nofollow would be unnecessary dangerous since they are somehow counted too and may have a negative impact on your SEO.
