Plugins are add-ons that extend your site’s functionality. From SEO and page builders to ecommerce and memberships, plugins let you add features or integrate your site with other services, all without writing custom code.

A WordPress.com website has many more built-in features than a self-hosted WordPress site, meaning you won’t need a plugin for many common features. Before installing a plugin, check this list to ensure the feature isn’t already available on your site.

Premium plugins often include more functionality, professional support, and ongoing development. The cost helps support the developers who maintain and improve the plugin over time. These plugins can be purchased directly from the developer. You can also purchase some popular plugins conveniently from within your WordPress.com account.

Yes. Developers can create custom plugins and upload them to WordPress.com on paid plans. You can also connect GitHub and use tools like WP-CLI for advanced workflows. Check out WordPress Studio for local plugin development.

Popular plugins include Yoast SEO, WooCommerce, Jetpack, and Elementor. They cover everything from search optimization to online stores.

On paid plans, go to your dashboard and click Plugins on the left-hand side. Browse or search the plugins directory, where you can learn about plugin features and see ratings. If you are happy with the plugin, click the “Install and activate” button to add it to your site. You can also upload a plugin ZIP file. For full instructions, see our guide to installing plugins.

Start with your goals. If you want more traffic, try an SEO plugin. If you need to sell products, add WooCommerce. Always check reviews, update history, and active installs to gauge reliability.

Plugin installation is available on all paid plans. Free plans come with a curated set of built-in features instead of external plugins.

You can deactivate the plugin from your dashboard, then reactivate plugins one by one to identify the cause. If you’re on a paid plan, our support team can help you troubleshoot.

Choose plugins with frequent updates, good documentation, and strong user ratings. A plugin with lots of active installs and recent support responses is generally more reliable.

Most plugins work with any theme. Still, it’s wise to preview changes in the Site Editor and check plugin documentation for any known conflicts.
