Facebook requires a bit of additional information on your webpages to properly integrate (Titles, Descriptions, Images, and Video inside the Timeline)
- Why do I need to do this?
- Obtaining Open Graph Information via the API
- Obtaining Open Graph Information from Viddler.com
Facebook will only pull full data (such as a video thumbnail, page title, or description) from a page if it contains “Open Graph” tags. Otherwise, pasting a link results in no thumbnail, no description, and even a title you may not want---Things that don’t lend themselves to click-throughs. Using Open Graph tags allow you to make a post that looks like this:
And even contain an in-timeline video player:
To get the Open Graph Tags to manually insert them into your page, open the Video Details Panel (clicking 'Edit' next to the video in your Videos list or the 'Edit' button on the Video’s page), select the 'Special embeds' tab, and choose 'Open Graph' from the drop-down menu:
In the URL field, place the address of the page you will be placing this code on. If you enter any other URL in this field, Facebook will read the code from that address instead.
Facebook Caches Open Graph Information
It is important to remember that Facebook will cache the Open Graph information the first time you insert a URL into a Facebook post. If you make updates
Use the Facebook Object Debugger
The Facebook Object Debugger will “refresh” the Open Graph Tags on a page. Use this if you make a mistake on the page’s tags, or if you change the tags on your page.
Facebook does not automatically update posts
You’ll need to delete and re-post your site on the timeline in order to have updates take effect.
