How to find WordPress Plugins and install them?

The two most common ways to finding WordPress Plugins, are:

1. Find free plugins within the WordPress Admin area.
2. The WordPress Admin Area is the administrative area of a WordPress website. Visit the WP-admin directory in your web browser:
   
   https://www.domainname.extension/wp-admin/
    

   IMPORTANT: You can only activate or deactivate WordPress Plugins, being the WordPress administrator. The administrator has full access to all sections within the WordPress Admin Area. Other users, with roles, such as editor, contributor or author, have limited access. Subscribers only have access to their profile page inside the admin area.

   2. Select “Install Plugins”.

   4. Enter the name of the selected plugin.
   5. Select a plugin among the most commonly used or recommended.
   6. Click “Activate the plugin”.
   7. Click “Install”.


3. Find free and paid plugins within WordPress directory
4. Search results inside the WordPress admin area are not always helpful. And limited to free plugins only. Most beginners find it difficult to decide which plugin is best for the job. As an alternative, search the WordPress directory. To find -both free and paid- plugins:
    
   1. Go to WordPress.org

   3. Use the Search box in the middle
   4. Enter the plugin name or functionality you want to add
   5. Click on the plugin name to select

   IMPORTANT: WordPress searches into the plugin directory. It displays the available plugins in a list. You still need to review the results and select the one that suits best.
