2. og:site_name The name of your website. e.g. IMDb not imdb.com.
3. og:url The URL that is the the unique identifier for your post. It should match your canonical URL used for SEO, and it should not include any session variables, user identifying parameters, or counters. If you use this improperly, likes and shares will not be aggregated for this URL and will be spread across all of the variations of the URL.
