What is the Open Graph protocol?
The protocol that allows you to share content from a web page on social networks is called "Open Graph". The Open Graph (OG) data is a set of tags giving structured and rich information about the content of a page from a website. In other words, when a user clicks on a share button, the default information will be the one inserted in the OG tags.
How to set up Open Graph tags?
Add the following line in your Html page:<html xmlns:og="http://ogp.me/ns#">
Add the meta tags with property and content attributes in the <head> tag, as for example below:
tag og:title
which corresponds to the title of your page, it must be less than 65 characters long: it is very similar to your classic Title tag!
tag og:description
which corresponds to a short description of your page, it must be less than 300 characters and it is very similar to your classic meta-description tag!
tag og:url
which corresponds to the url of your web page >> so try to optimize your url !
tag og:image
which represents the image of your page that will be shared on social networks = URL of the image that represents your page
tag og:site_name
which is the url of your site = global name of your website
Warning: not all tags are essential, but some are! You must absolutely specify the 4 tags: og:title, og:type, og:url, og:image
You can extract this information in your SmartKeyword account by going to "My Keywords" > "optimize" > "technical" then in the Open Graph section of the "Action Plan" for a given word.
