Custom Post Types (CPTs) are a fantastic feature within WordPress. They allow you to define your own Post Type and how it operates within WordPress. As an example, if you're creating a movie review site you might make a Custom Post Type called ‘movies' and include Custom Meta Boxes and seperate entry fields for data such as “Genre”, “Release Date”, “Director”, etc., rather than adding all the content into the standard edit field. This makes for much easier to manage data when displaying it within your theme.
