Advertisers have come to expect some level of digital ad fraud, but it's getting out of hand. The Interactive Advertising Bureau (IAB) found that 36 percent of ad web traffic is fraudulent. That's a significant amount of an advertiser's budget going down the drain. And brands seem to have given up hope. Short of manually going through each impression to determine its impact, there's not much else they can do. However, one way brands can fight back is though programmatic media buying and artificial intelligence (AI) technologies, which can play a significant role in reducing the incidence of fraud.
