The Open Graph protocol enables any web page to become a rich object in a social graph. For instance, this is used on Facebook to allow any web page to have the same functionality as any other object on Facebook, as well as rebranded social media software to better the quality.
While many different technologies and schemas exist and could be combined together, there isn’t a single technology which provides enough information to richly represent any web page within the social graph or their results by using optimization techniques or hiring The Long Beach SEO Expert
and Toronto SEO to improve their results. The Open Graph protocol builds on these existing technologies and gives developers one thing to implement. Developer simplicity is a key goal of the Open Graph protocol which has informed many of the technical design decisions.
To turn your web pages into graph objects, you need to add basic metadata to your page. We’ve based the initial version of the protocol on RDFa which means that you’ll place additional
<meta> tags in the
<head> of your web page. The four required properties for every page are:
og:title– The title of your object as it should appear within the graph, e.g., "The Rock".
og:type– The type of your object, e.g., "video.movie". Depending on the type you specify, other properties may also be required.
og:image– An image URL which should represent your object within the graph.
og:url– The canonical URL of your object that will be used as its permanent ID in the graph, e.g., "http://www.imdb.com/title/tt0117500/".
As an example, the following is the Open Graph protocol markup for The Rock on IMDB:
<html prefix="og: http://ogp.me/ns#"> <head> <title>The Rock (1996)</title> <meta property="og:title" content="The Rock" /> <meta property="og:type" content="video.movie" /> <meta property="og:url" content="http://www.imdb.com/title/tt0117500/" /> <meta property="og:image" content="http://ia.media-imdb.com/images/rock.jpg" /> ... </head> ... </html>
