A plugin is a piece of software containing a group of functions that can be added to a WordPress website. They can extend functionality or add new features to your WordPress websites. WordPress plugins are written in the PHP programming language and integrate seamlessly with WordPress.
In the WordPress community, there is a saying that goes around: “there’s a plugin for that”. WordPress makes it incredibly easy for users to add features to their website without knowing a single line of code. There are thousands available for free to download at the official WordPress plugin directory.
As a site administrator, you can install/uninstall plugins from the admin area. You can also download and manually install them using an FTP client.
Because the vast majority of plugins are free, it is important to note that they usually do not come with tech support. For this reason, it is important to be careful when choosing which ones you want to install on your site. Although there are plugins that can do virtually anything, some are much higher quality than others. In order to choose the right ones, you should ask yourself a couple questions. How long has it been since it was updated? Is it compatible with the latest version of WordPress? Are people getting answers to their support questions? What type of rating does it have?
