Facebook – How to get share counts using graph API

This technique is now deprecated.

This used to tell Google how to index the page.

https://developers.google.com/webmasters/ajax-crawling/

This technique has mostly been supplanted by the ability to use the JavaScript History API that was introduced alongside HTML5. For a URL like www.example.com/ajax.html#!key=value, Google will check the URL www.example.com/ajax.html?_escaped_fragment_=key=value to fetch a non-AJAX version of the contents.

Couldn't find this in the documentation but multiple calls to the API are not necessary. You can use summary when querying a feed or multiple posts. Specify this in the fields parameter.

https://graph.facebook.com/PAGE_ID/feed?fields=comments.limit(1).summary(true),likes.limit(1).summary(true)

This will return a response like this.

{
  "data": [
    {
      ....
      "summary": {
        "total_count": 56
      }
      ...
    }, 
    {
      ....
      "summary": {
        "total_count": 88
      }
      ...
    }
  ]
}

This will be much faster than making individual requests for each object just to get the number of comments or likes.
