Call of Duty Wiki:Categorizing

This is a quick overview on Categorizing pages.

What not to do
Do not add a base category to a page, such as adding Category:Call of Duty: Black Ops, to a page about content in Black Ops. There are already subcategories that cover specific parts of a game, such as perks. Put pages in those categories instead. Placing pages in the base category simply clutters it and defeats the point of it, which is to link to other categories related to the page.

Do not add game-related categories to blogs. These are here to categorize game-related pages, not blogs.
