Facebook is reported to have started testing a Buy Tickets button (according to AllFacebook), where users can now buy tickets to events they feel like attending. The flip side, the button does not lead to any place within Facebook. Instead users are still directed to third party websites. The button appears within News Feed stories of the event and within the upcoming events section.
However it is a possibility that Facebook might change the way the buy ticket button functions and might start taking the transactions in its own hands. If this does happen, online marketing trends will shift heavily towards Facebook, since the ease with which events can be created and tickets sold will attract a lot of viewership. This could also help in viewing user trends for a particular event or series of events. It is not known when the functionality will be rolled out, but when it is rolled out, Facebook events will see higher traffic.
At present, individual users do not have the capability to add the option of adding a ticket link. However Facebook pages can create events with links to tickets. These links then become a “buy tickets” button.
