Developing content gets users to your site. Dripping content keeps them there.
Dripping content is a method of releasing content to your site users. Users receive content bit by bit, perhaps over the course of a few months, until they have access to the full library.
You can also drip specific menu items or posts, requiring a user to view them in a certain order. Even requiring a user to provide an email before being allowed to see more of your site could be considered content dripping.
One popular reason for implementing content drip is when you are creating an online course and you want the course to be completed within a certain time frame.
Drip content often requires users to interact more frequently with your site. Since they don’t get all the information at once, they need to come back.
