Brand Safety

Nine works with Grapeshot to provide brand safety across its network for display campaigns. Using Grapeshot’s technology, Nine can target Advertiser campaigns away from articles that may be considered unsafe. This can be either through Grapeshot’s standard brand safety segments or via a custom brand safety segments built for an Advertiser using their specific key words. Please speak to your Nine sales representative before planning your campaign to learn about what brand safety targeting is available and associated pricing.
