Get into the Widget-mania
Widgets are a nice and sneaky way to make someone do what you want.
There are various of them, others conquer the whole page, other a small box, other a bar at the bottom or header.
These widgets will help you boost your conversion for sure as they are sure to draw the attention and remind the ones visiting your web page something important.
You can use them to gather emails, get people back to their cart, distribute freebies and pretty much everything.
I would strongly suggest heading over to Appocalypsis, a ridiculously easy way to create jaw-dropping widgets.
