The Hill – ‘Facebook is giving advertisers new information about how users notice and act on ads as they move between their computers, smartphones and tablets. In a post on Wednesday, Facebook said that it would begin allowing companies that advertise on the social media site “to see for the first time how people are moving between devices — across mobile apps and the web — before they” act on the ad, such as purchasing an advertised product. “Imagine seeing an ad for a product on your mobile phone while in line at the bank. Do you immediately make a purchase on your phone? Probably not,” the company wrote. “But perhaps you go back to your office later that day and buy on your desktop computer.” Building off of existing tools, advertisers will now be able to see how users move between iPhones, Android phones and iPads as they see and then act on ads on Facebook…”
