I make use of Schema information on my Web site and add additional info for Google+. It was an effort to add more social site improvements. Originally I could use the code from the default WordPress meta description
<?php bloginfo('description'); ?>
to fill in values for the code below. However, after using the plugin to remove the default meta tag, I wanted to know if the plugin could include the following as well as your opinion on its usefulness for SEO:
<!-- Add the following tag inside head for Google+1 -->
<meta itemprop="name" content="SOME NAME">
<meta http-equiv="content-type" content="text/html; charset=UTF-8" />
<meta itemprop="description" content="SOME DESCRIPTION">
