WordPress comes with many default content types, such as image, video, gallery, audio, aside and so-on.
But what if you need more flexibility?
What if you need to make your onw content types?
Easy — using the WordPress API, you can create your own custom post types, taxonomies, and metadata. Whatever you are selling or whatever service you provide, WordPress can be customised to your business.
So you can take WordPress in whatever direction your business needs.
