On my website I put
noindex on my category pages but not the pages under it. Even though two weeks passed, the only indexed page is my home page which is not under any category.
When I look at yandex webmasters, under indexing>statistics>excluded pages I see both
www.example.com/category/. I wonder if
www.example.com/category/ (slash at the end) means "I am not indexing any pages under it" and
www.example.com/category means I am not indexing the category.
