What is Open Graph Protocol (OGP)?

Open Graph Protocol

Open graph tags are meta tags that help reflect data such as titles, descriptions, and images when sharing web pages on social media. It was created for the first time by Facebook.

They are used with <meta> tags inside the <head> tag in HTML language.

Basic OGP Meta Tags

You can use open graph tags in the simplest way by placing the following 4 meta tags in the source code of the page. These 4 meta tags are required on all pages for the build to work.

  • og:type Specifies the type of page. (Article, video, author…)
  • og:title Specifies the title of the page.
  • og:image Specifies the cover image that describes the page.
  • og:url Specifies the canonical URL that created the page.


<meta property="og:type" content="article">
<meta property="og:title" content="Nikola Tesla Quotes - Words From Life">
<meta property="og:image" content="https://wordsfromlife.com/img/static/nikola-tesla.jpg">
<meta property="og:url" content="https://wordsfromlife.com/en/nikola-tesla-quotes">

Optional OGP Tags

The following meta tags are optional for the Open Graph Protocol but generally recommended.

  • og:audio It is used to specify the URL of the audio file to be shared.
  • og:video It is used to specify the URL of the video file to be shared.
  • og:description A description is used to describe the page, usually it pulls the same value as the meta description tag of the page.
  • og:determiner It is used for the word that will appear before the title of the page. Such as the prefixes “a”, “an” or “the” in English texts. It is blank by default.
  • og:locale Used to mark the local language of the page. Its default value is “en_US”.
  • og:locale:alternate It is used for the alternative locations of the page that are available. It can be used as an array for multiple alternate pages.
  • og:site_name Used to specify the name of the website.
