I am starting a blogging site and I am trying to figure out how to put different ad codes in each category of posts. For example, I want to put ads about pets and animals in the "Pets" category.
I am making each blog (which is available to users) have many different categories, where they can organize each of their posts.
So when I click on "Pets" in the list of categories at the bottom right of each blog's home page, it will take me to all that blog's posts listed under "Pets", and it will show pet ads. Same with other categories, too. Is this possible? If so, how do I configure this and what files do I change?
Thanks for your help, I am new to wordpress.
