Mumbai: Worldpanel India, part of Kantar, in partnership with SYNCMedia, has launched India’s first deterministic, single-source, cross-platform attribution framework—marking a significant shift in how advertisers measure the effectiveness of video advertising across screens.
The new study moves the industry beyond traditional probabilistic reach models to deliver people-level measurement that directly links advertising exposure to real online actions. For the first time in India, advertisers can now assess unified performance across Linear TV, digital video, and OTT platforms, not just in terms of reach but in terms of tangible business outcomes such as search, website visits, e-commerce and quick-commerce activity.
From Reach to Results
Historically, while cross-platform reach could be estimated, attributing outcomes to specific media exposures remained elusive. Worldpanel India and SYNCMedia’s deterministic panel addresses this gap by capturing real ad exposure across screens and tying it to actual consumer behaviour.
Early campaign analyses spanning categories such as automobiles, insurance, banking, handsets, consumer durables, online apps and FMCG reveal a clear hierarchy in performance across platforms—underscoring Linear TV’s continued relevance in driving digital actions.
Key Findings Highlight Linear TV’s Strength
The study shows that audiences exposed only to Linear TV delivered 15–25% higher online search conversions compared to those exposed solely to user-generated content (UGC) video platforms. The strongest performance, however, came from cross-screen exposure, where viewers reached through both Linear TV and digital video generated over 50% higher conversions on average versus solus UGC exposure.
In terms of scale, Linear TV continues to act as the backbone of reach, delivering 50–100% more audiences than the largest UGC platform, along with three to four times higher exclusive reach. While solus digital exposure was more effective at driving website visits—outperforming solus Linear TV by 30–50%—a combined TV-plus-digital strategy consistently delivered superior results across the entire conversion funnel.
Industry Reactions
Commenting on the relevance of the framework, Samir Sethi, Head of Brand Marketing at Policybazaar, said the ability to map cross-screen attribution to business metrics would strengthen evidence-based media planning. He noted that the approach helps move brands away from assumption-led, siloed planning toward a more integrated understanding of cross-platform consumption behaviour.
K Ramakrishnan, Managing Director – South Asia, Worldpanel by Numerator, described the initiative as a “game changer” for brands seeking a unified view of media effectiveness. He added that the single-source panel will expand in size and coverage through 2026, helping FMCG marketers finally validate long-debated claims around the short-term sales impact of video advertising.
Anubhav Sharma, CEO and Founder of SYNCMedia, said the future of media measurement lies in deterministic truth rather than assumptions. By combining real exposure capture with real business actions, he said, brands can move beyond channel-centric debates and focus on what actually drives growth.
How the Panel Works
The jointly created single-source panel currently comprises smartphone users across India’s top six metros. Participants install SYNCMedia’s SYNC Pulse mobile app, which uses Automatic Content Recognition (ACR) to detect ad exposure across screens. This is complemented by computer vision and mobile-level fingerprinting to track real behaviour across web, e-commerce and quick-commerce platforms—directly linking exposure to outcomes.
With this launch, advertisers gain access to granular, cohort-wise attribution segmented by exposure source, enabling sharper media allocation decisions and improved business impact. As the panel scales further, the initiative is expected to play a pivotal role in reshaping how cross-platform video effectiveness is measured in India.
