Retailers sell their products through paid marketing on Facebook besides organic selling. Facebook offers paid advertisements for your products. During the Facebook Ad setup, sellers can target users precisely to whom they want to display their ads. This brings a difference while calculating the ROI. Even if a dynamic advertisement option is chosen, vendors can set up a retargeting. In the case of retargeting ads, if a user has engaged with the ad displayed then that ad is shown to the user on all affiliated Facebook network sites online. This enhances the overall sales.
