With the Performance Settings you have the ability to clean up the code within the header of your website. WordPress adds some extra code as default to every site which isn't really needed and if you check the box "Cleanup Header" then Social SEO Pro will strip out that code. Below is the code which the plugin will strip out:


<link rel="alternate" type="application/rss+xml" title="WP Social DEV &raquo; Feed" href="http://www.wpsocial.dev/feed/" />
<link rel="alternate" type="application/rss+xml" title="WP Social DEV &raquo; Comments Feed" href="http://www.wpsocial.dev/comments/feed/" />
<link rel="EditURI" type="application/rsd+xml" title="RSD" href="http://www.wpsocial.dev/xmlrpc.php?rsd" />
<link rel="wlwmanifest" type="application/wlwmanifest+xml" href="http://www.wpsocial.dev/wp-includes/wlwmanifest.xml" />
<meta name="generator" content="WordPress 3.6" />

 


Dashboard Widgets


By activating this option, Social SEO Pro will disable the following widgets within the Dashboard:

  • WordPress Blog
  • Other WordPress News
  • Incoming Links
  • Plugins


When you deactivate the options within the settings page, these widgets will be displayed again.


HTML5 Boilerplate .htaccess


By activating this option, Social SEO Pro will add some entries to your site's .htaccess file to optimize the site for better performance. These are the .htaccess settings recommended by the HTML5 Boilerplate project. 


After you activated the .htaccess option, go to Permalinks > Settings and re-save the permalinks. You don't need to change anything, just save them again to make sure, all the code gets added to the .htaccess file.


Below is the code which is being added to your site's .htaccess file:


# BEGIN HTML5 Boilerplate




# This contains the HTML5 Boilerplate .htaccess that can be found at:
# github.com/h5bp/html5-boilerplate/blob/master/.htaccess
#
# Added:
# Block access to access to WordPress files that reveal version information.
#
# Commented out by default:
# Expires headers: Use WP Super Cache or W3 Total Cache (unless using the H5BP build script)
# ETag removal: Use WP Super Cache or W3 Total Cache (unless using the H5BP build script)
# Start rewrite engine: Handled by WordPress
# Suppress/force www: Handled by WordPress
# Custom 404 page: Handled by WordPress
#
# Anytime you update this file the .htaccess file in the root of your
# WordPress install is automatically updated with the changes whenever
# the permalinks are flushed or set
