What is a Plugin?
WordPress plugins are add-ons that enable you to extend the Content Management System’s (CMS) functionality. You can use plugins for almost everything, from adding e-commerce features to WordPress to implementing page builders or using Search Engine Optimization (SEO) tools.
More About Plugins
One of the main upsides of using WordPress is choosing from literally dozens of thousands of plugins, both free and premium.
At any time, you can look up plugins without leaving the dashboard and install and test new options in minutes. That convenience makes it easy to test new features for your website without committing resources to custom development.
Most WordPress websites use multiple plugins. You can also develop custom plugins if you have coding knowledge. Those plugins can be for personal use only, or you can choose to sell them in the sizable online market.
