Google Indexed our variation page
Hello, we recently ran a split test for our homepage. The variation was called /index_new after the url which we didn't want indexing so we put a robotsnoindex on it but google has somehow indexed this page and affected our rankings because of duplicate content. Why has this happened?

Anyway, for what I know it's a best practice to use the rel=canonical for this situation. Where you say that "index_new" belongs to "index", so the search engine would not consider it as a duplicate.
