Brand Safety

"We take Brand Safety very seriously. We are implementing global standards for all of the digital risk areas like, Viewability, Fraud, Privacy infringement, Anti-Piracy, Appropriate placement. As clients move more of their investment from linear channels to digital, they need to be assured that their brand messaging is seen by real humans, in the right target audience and in an appropriate environment."

John Montgomery

As new opportunities with data and measurability emerge in the digital supply chain, so do complexities. These complexities open the door for inevitable risks—including, but not limited to, fraud, piracy, viewability, privacy infringement and appropriate targeting and placement. As clients are moving more funds from linear to digital media, they are increasingly concerned that their brands are safe, and being shown to the right people, in the right place, at the right time. GroupM takes a leadership role in the navigation of these complex digital environments, creating and collaborating on stringent standards and best practices so clients can be assured that their campaigns are being viewed in brand safe environments, and that the consumer experience can be both protected and enjoyable.
