Plugins

WordPress plugins are relatively small pieces of web software that can be installed on any WordPress site. They extend the native functionality to do almost anything that the technology of today allows. Just like WordPress itself, the code within plugins is open source, which means that anyone can build a new plugin if they have the required skill set. Every WordPress website or blog can work with an unlimited number of plugins (although it is not a recommended approach). The most popular functionalities introduced through plugins include spam protection, search engine optimization (SEO), caching, social media integration, interactive contact forms, and backups.
