Hi !

The advantage of using the social proof widget is the possibility to shorten the time to make a purchase decision by creating an impression of competition in access to limited goods. Moreover, we can increase the attractiveness of the product by showing the number of users who also displayed the product. The social proof widget helps to increase sales conversion by showing how many people have already bought a product recently as well as increase customer engagement by interacting with them through dynamic animations.
