"Media is increasingly important in customer relationship management.

Brand Safety

"As advertisers move more of their investments from linear to digital mediums, they need assurance their brands are being seen by real people, not bots, in the right audience target, and in an appropriate environment."

John Montgomery

EVP of Brand Safety, GroupM Global

Consumer adoption of digital and social media platforms has enabled incredible opportunities for brands to connect directly with their consumers, but there are risks. Brand owners need the confidence that their messages are being received by the right people in the right context. Rightly, they also deserve standards and measures that support accountability and create trust.   

GroupM has participated in or led every significant effort to increase the integrity of digital marketplaces worldwide. We’ve created or collaborated to define strict standards and advertising best practices that balance the needs of advertisers, publishers and consumers.
