ThirstyAffiliates is a popular WordPress plugin to manage affiliate links easily. It gives bloggers the tools they need to monetize their website with affiliate marketing. There are no complex setups. It is just another type of post in the admin and a button in the Visual Editor. Creating hierarchical categories for links can make managing them faster. Example: placing all Amazon links within an “Amazon” category or all software links in a “Software” category.
