To install the Free version from the admin interface, follow the Automated Install method described bellow.


If you have purchased the Pro version, an email will be sent to you with an Authentication ID and installation instructions. Enter your Authentication ID on the SSO Pro Licenses settings page, and after saving the changes, an update will appear on the WordPress Updates page. Update the WPSSO plugin from within WordPress, as you would any other plugin, to download and activate the new Pro version.


If you downloaded the WPSSO plugin as an archive file, follow the Automated Removal (if necessary) and the Semi-Automated Install methods to install and activate the new plugin. Please take care to check the “Preserve Settings on Uninstall” option on the Advanced settings page before removing the plugin (as explained in the Automated Removal procedure).


If you need to roll-back and re-install an older Free version, you can find them all on the WordPress.org Developers page.


Automated Install (Free version)

  1. Go to the wp-admin/ section of your website
  2. Select the Plugins menu item
  3. Select the Add New sub-menu item

  5. Click the Search Plugins button
  6. Click the Install Now link for the “WordPress Social Sharing Optimization (WPSSO)” plugin

Semi-Automated Install
(Free and Pro versions)


If you already have WPSSO installed, you will have to remove it first before you can re-install it using this method. Don’t forget to check the “Preserve Settings on Uninstall” option on the Advanced settings page before removing the plugin (as explained in the Automated Removal procedure).

  1. Download the plugin archive file
  2. Go to the wp-admin/ section of your website
  3. Select the Plugins menu item
  4. Select the Add New sub-menu item
  5. Click on Upload link (just under the Install Plugins page title)
  6. Click the Browse… button
  7. Navigate your local folders / directories and choose the zip file you downloaded previously
  8. Click on the Install Now button
  9. Click the Activate Plugin link


Manual Install
(Free and Pro versions)

  1. Download and unzip the plugin archive file
  2. Upload the entire wpsso/ folder to your website’s wordpress/wp-content/plugins/ directory
  3. Go to the wp-admin/ section of your website
  4. Select the Plugins menu item
  5. Select the Installed Plugins sub-menu
  6. Scroll down to the “WordPress Social Sharing Optimization (WPSSO)” plugin, and click its Activate link


Once installed and activated, the WPSSO plugin will start adding all the essential Open Graph meta tags to your webpages immediately — there’s no need to configure any additional settings. Although if you have at least one image in your Media Library or NextGEN Gallery that represents your website, you may want to define that one as your Default Image on the General Settings page.


The plugin settings are available under the SSO admin menu, where you can select a default image, change the shared image dimensions, and much, much more.
