Get reviews from SearchReviews.com on your website.
One optional setting should be configured before use of the plugin. If you have a Publisher ID (you can sign up at http://searchreviews.com/publisher ), enter it in the widget settings screen.
Posts and pages have a "SearchReviews.com Widget" meta-box. Just add keywords to this box to trigger the widget. Using the widget is optional - if you don't add keywords, the widget won't appear.
