Up to $8.6 billion of sales will be lost due to cart abandonment this holiday season especially during the earliest days. There are plenty of reasons why holiday shoppers won't push through the "Buy" button right away. Luckily, you can still reach back to the ones who got away earlier in the holidays to remind them of their abandoned holiday carts.

While retargeting, also known as remarketing, is a helpful year-round tool, it is one tactic that should not overlook during the holiday season. With heightened holiday competition, you need an easy way to remind your shoppers that they've not completed their holiday purchase. And this is what retargeting does best.

You can implement a holiday retargeting campaign using Dynamic Product Ads. This tool allows you to run ads that specifically target people who visited your website and added an item to their carts without making a purchase. So that the next time users log in Facebook, they'll automatically be displayed with an ad reminding them of their abandoned carts.
