Whether you want to create a poll or run a photo contest, social media and messaging services play a major role in inviting participants. If you share the link to your PollUnit in your Facebook stream, via WhatsApp, in Twitter or similar, the app will read the social media tags. This metadata describes how the link should be displayed. In most cases this includes a graphic, headline and a short description.
At the bottom of the Share dialog you will find a link »Change content (Social Media Tags)«. If you click this link, you can edit the metadata and add your own graphic. A small preview shows you how Facebook, WhatsApp and Co. will display the link to your PollUnit.
