A popup is a type of window that appears on top of the main content of a website. This window typically displays additional information or a call to action triggered by an event, such as clicking a button or link. Popups are often used to display important messages, offers, or forms, effectively engaging visitors and encouraging them to take a specific action.

WordPress, the most popular CMS, provides several methods to add popups to your website. It offers a lot of pluggable additions called plugins. 

You might want to use a popup plugin on your WordPress site for several reasons. Popups can be a great way to draw attention to important information or offers. They can also help you engage your visitors and encourage them to take specific actions, such as signing up for a newsletter or purchasing. Popup plugins also provide an easy way to manage and customize your popups, allowing you to control when and how they are displayed on your site. Using a popup plugin can help you improve your site’s user experience, leading to better conversion rates and more success for your business or organization.
