A plugin is a packaged set of files designed to extend the functionality of WordPress. These often come as a .zip format file that is uploaded and then enabled from within the WordPress dashboard. Plugins offer custom functions and features so that each user can tailor their site to their specific needs.
Official WordPress plugins are available from several sources. However, a variety of plugins are available to download and use if you wish.
Not all Plugins are Good
Some plugins can actually decrease your site's performance and speed, possibly damaging your SEO ranking due to downtime. Certain SEO and sitemap plugins (such as the All in One SEO Pack and Google Sitemap, respectively) are known to cause issues. WordPress is already built on an SEO platform, complete with a built-in sitemap.

The Effects of a Bad Plugin
All plugins alter the core files of WordPress and can change the way WordPress functions. This can lead to unexpected and possibly negative results. In severe cases, improperly coded or outdated plugins can cause damage to your site including:
- The inability to log in to your WordPress dashboard.
- Your site loading slowly or not loading at all.
- Damaged databases.
- Damaged site content.
Additionally, deprecated plugins can allow serious security exploits on your site. HostGator strongly recommends that any plugins you use be checked for compatibility with your version of WordPress and with any other plugins you use.
