Yoast SEO Premium v2.2.2

The WordPress SEO premium plugin adds several features to the WordPress SEO plugin. At the moment, the extra included functionality includes:

• A redirect manager
  This allows you to create and manage redirects from within your WordPress install, allowing you to easily redirect old URLs to new ones, and solve common issues. This is especially powerful because of the combination with the Google Webmaster Tools integration.
  Built for scale, this redirect module can either handle the redirects for you or generate a redirect file that you can include in your Apache or NGINX server config.
• Tutorial videos for the entire plugin
  Don’t understand a section of the plugin? Don’t know what to do with the page analysis box? Don’t fret: the premium version comes with 17 tutorials videos explaining every setting the plugin has in detail. You can see an example video below!
• Integration with Google Webmaster Tools
  The integration with Google Webmaster Tools in WordPress SEO premium allows you to retrieve crawl errors from Google Webmaster Tools and fix them immediately using the redirect manager.
