A floating bar becomes visible either when customers start to scroll/swipe down or when customers scroll/swipe beyond the original Outlink button. The bar contains the Outlink button so your customers can quickly click the external link without going back up to the original Outlink button.
The sticky Outlink button makes it as easy as possible for your customers to make a click and thereby improve your conversions.
