Open Graph and its impact on SEO

Definition of the Open Graph protocol

The official definition of the Open Graph protocol indicates that this is a protocol which allows a web page to become a "rich" object in a social network.

More specifically, the Open Graph Protocol is a set of tags that allows a webmaster to give major social networks (Facebook, Google +, Twitter, Linked in...) detailed information about its pages. This information will allow social networks to better display a link on those pages that have been placed by the users.

The Open Graph protocol has been originally created by Facebook and is now managed by the Open Web Fondation.

What is the impact of the Open Graph on SEO ?

In theory, the impact of the Open Graph on SEO is limited. Actually, the Open Graph protocol is intended primarily to social networks (Facebook, Google +, Twitter...) and not to search engines (Google, Bing...)

In practice, however, the social networks, like Facebook for example, have become so important in recent years that the search engines can’t ignore the Open Graph data in their algorithms. It would be adventurous enough to accurately describe the impact of this kind of data, but its impact undoubtedly exists. It is also certain that the major search engines analyze these Open Graph tags. In particular, Google may tend to favor pages used in its Google + social network.

For SEO, historically, the webmasters should primarily focus their attention on the title and meta description tags of their pages. Today, it is equally important to add Open Graph tags on the web pages, particularly if these pages are frequently shared on social networks like Facebook.

Placing Open Graph tags

To add the Open Graph protocol, you must simply:

  • Add the namespace "" to the html tag
  • Between the head tags, you must add the meta tags with their property and content attributes
  • The specifications define 4 Open Graph tags like "Requirements" : og:title, og:type, og:url, og:image
  • Other tags are also useful, especially if your page has a rich content (video)

Here is a detailed example of Open Graph data implemeting:

<html xmlns:og="">

<meta property="og:title" content="Article on the Open Graph by Yakaferci" />
