PreView FAQs

PreView is a SaaS advertising testing platform that measures human response to video advertising at scale. PreView is built on the most advanced facial coding technology and machine learning to provide marketers a true measure of consumer attention and emotional response to video. Marketers can launch campaigns with confidence knowing their ad creative is optimised for Attentive Reach.

PreView is designed for today’s marketer who needs to test and compare creative concepts, durations and their context (channel and device), to deliver the greatest return on ad spend.

PreView uses front-facing cameras to analyze facial coding data of anonymous opt-in viewers as they watch video content online in their home environment. This aggregated attention and emotion data is reported to the dashboard to provide comparative creative intelligence that enables advertisers to launch their most effective creative.

Speed, scale and efficiency is the key differentiator between PreView Ad Testing and traditional research methodologies. PreView is a natural viewing experience, using any device with a front-facing camera with no software to install. Access viewers from all over the world, with results typically delivered within 48 hours. 

Traditional methodologies are typically process heavy, costly, difficult to scale and compromise the respondent’s viewing experience. 

Using an attentive reach model throughout a campaign can achieve significant impact gains and can reduce waste by as much as 30% through creative quality selection alone. Over time, individual campaigns contribute to valuable attention performance benchmarks to continuously improve advertising planning, flighting and assessment.
