This add-on allows users to evaluate a thread inside the forum/site. It is the functional equivalent to the rating function of resources. The users could not only see a thread, they could also access it for good-bad content, the quality of the thread… Those valuations could help a lot for the recommendation, so a new user could choose the high rating thread first when he/she is going to the forum for the first time in his/her life. It also encourages the thread owners to post more useful content if they have high rating threads or the administrator could know the trend of content following what the user voted before.
This add-on has an extrovert function that is displayed the rating right on the Search page of Google. It could also support for Rich Snippets & Structured Data of Google. If Google understands the content on your pages, we can create rich snippets—detailed information intended to help users with specific queries. For example, the snippet for a thread might show the average rating of that thread.These rich snippets help users recognize when your site is relevant to their search, and may result in more clicks to the threads.
