Abstract: A system and method for creating shareable Internet-based advertisements includes an administration console receiving data related to an Internet-based advertisement, and configuring an overlay to provide on top of the Internet-based advertisement. A database operatively connected to the administration console stores data and code related to the overlay and the Internet-based advertisement. A share tag is applied to the Internet-based advertisement. Upon activation of the share tag, a share tag server retrieves the stored data and code and displays the overlay on the Internet-based advertisement as an expanded share tag. Upon activation of a share feature on the expanded share tag, the share tag server provides, to a desired social media network server, the stored data needed to display the Internet-based advertisement on the user's social media network page. The Internet-based advertisement is displayed on the user's social media network page, and may be further shared by others.
