Trust Metrics is a brand safety planning tool for programmatic advertising founded on the principles of print publishing and the idea that high quality publishers are best suited to host the best quality ads. Beginning about a decade ago, programmatic buying was devaluing the hard work that many legacy publishers put into their editorial, so Trust Metrics sought to reward good content online by informing brand advertisers where to find it and defining exactly what made it superior. While other vendors define quality environments as those that simply lack safety concerns, Trust Metrics goes deeper and looks at content for quality features including freshness of content, page design, user experience, depth and breadth of editorial, and hundreds of other unique features to generate an overall quality score and safety ratings. Achieving this work through a combination of machine and human analysis, our ratings provide the much-needed insight for advertisers who simply don't have the resources to evaluate and monitor tens of thousands of domains on their own. Each Advertiser has different thresholds of suitability in quality, safety, and contextual targeting and we use our scoring system to create custom scalable whitelists that help provide more confidence to buying at scale.
