Clicking on the 
icon when it appears on a page displays a set of social media sharing buttons for the page. For example, buttons for Facebook and Twitter.
Clicking on any of those buttons allows you to share the page address if you have an account on that particular social media platform.
•Many websites use social media buttons and code provided by 3rd-parties who track usage of those button. The IP Office Knowledgebase uses its own code to provide the buttons and does not perform any tracking or reporting of what you share or with who you share it.
