This form, although many people know it, but many people have it. The paging of news and products if not processed, you will see error messages in WMT always through the improvement section of the HTML section of the title and description.

6. Incomplete form of duplication:

Usually happens with pages that use the free tag mechanism or have an unstructured portfolio structure. This is a common format for wordpress sites that have no clear management mechanism for tags and categories. You already have a category of "A-type products" that you have a tag of "Category A products", or more specifically the "Baby items" and Tag "baby supplies" list then what is up. Understanding is that your A-class product is 2 pages in existence, talking about it. It is not exactly a 100% duplicate content but it is a similar content, it will also directly affect the quality of your website.
