Like it or not, Facebook advertisements just got even smarter. On Tuesday, the social network announced Product Ads, a set of tools that lets businesses more effectively target Facebook's 1.4 billion or so users with a new, automated process. SEE ALSO: Facebook is rethinking how it tracks ads With Product Ads, businesses who upload their product catalogs to Facebook can manually create ad campaigns. The other, more compelling option? Let Facebook do the heavy-lifting, automatically creating campaigns and targeting various kinds of users with ads it thinks will perform well, based on things like a user's interests, general location and whether they've already been to the advertiser's app or website. In a Facebook first, businesses can also now create ads that promote several products at once. Ads that used to be static now act as digital carousels of content, with up to five product images rotating through, like in the image below: Product Ads could prove useful to businesses with deep inventories of attractive products: furniture chains, clothing franchises and so on. (For one, those multi-product ads increase the odds of users finding items to buy.) It's also a potential win for Facebook, which gets the majority of its growing revenues via advertising on desktop and mobile. The loser? Shoppers' wallets.
