You can now turn your SweepWidget giveaway into a modal popup on your webpage! First, edit or create a giveaway. Then, on the embed page you must tick the check box that says Make widget a popup in embedded pages. Now, you can select how many seconds you want it to wait until the widget pops up.
As you can see, the widget will pop up as a modal. There is a convenient X in the top right corner which allows the user to close the widget.
IMPORTANT: after adding this feature, you must add the new embed code to your website (if you already had an old embed code).
