System1 Group PLC has launched its new System1 Ad Ratings service for brands and advertisers as a way for brands to understand the potential of their campaigns to drive long-term growth. The service is launching with two years of data covering over 27,000 TV ads from the USA and UK. Once an ad has aired on TV it is typically available on the platform the very next day. System1 Ad Ratings analyses ads in over 100 categories providing advertisers and brand managers a platform to benchmark the performance of their ads and predict potential long term brand growth. Ad Ratings works by measuring the emotions the ad generates in the consumer and the intensity of that emotional resonance. This produces a Star Rating from 1-5 stars. The Star Rating predicts Long-term brand growth potential: 1-Star equals 0% brand growth, whereas 5-Stars equates to 3%+ long term brand growth potential. The prediction side of the tool has been independently validated in conjunction with the IPA. Using submissions to the IPA Effectiveness Awards, one of the most robust submission procedures in the industry, System1 cross-referenced emotional resonance real-world brand growth in various categories, and the system was modelled on those results.
