Results

1. Executive Summary
Dettol Original Soap drove penetration in TV-dark rural UP and Maharashtra by targeting female cord-cutters/nevers (25-44) on YouTube. The "Driving Penetration" campaign achieved exceptional ROAS (2.3 UP, 1.9 Maharashtra), significant sales uplift (6.2% UP, 4.9% Maharashtra), and 60% incremental reach (4+ frequency), demonstrating digital's power for robust ROI and deep market penetration where traditional media failed.
2. The Challenge
Crucial rural markets (40% of business) in UP and Maharashtra presented a significant challenge for Dettol Original Soap. Low linear TV penetration created "TV dark markets," rendering conventional advertising ineffective. This barrier to brand penetration and sales demanded an efficient, alternative media solution that can identify audiences not exposed through TV for incremental growth.
3. Objectives
Running Nov’25–Feb’26, objectives were:
• Drive Dettol Original Soap penetration in TV-dark rural UP & Maharashtr.
• Achieve significant incremental reach over traditional TV by identifying data signals of Cord Cutters and Cord Nevers (i.e people who are not exposed to TV) • Generate measurable sales growth in both states.
4. Strategy & Execution
Adapting to evolving media consumption, the campaign strategically pivoted to YouTube, targeting female cord-cutters/nevers (25-44). The strategy drove high reach (4+ frequency) and optimal dispersion using a tailored mix of YouTube ad formats: Non-skip Video Assets, YouTube Shorts, and YouTube Bumpers. This multi-format approach effectively built brand presence among previously unreachable audiences.
5. Results & Return on Investment
The "Driving Penetration" campaign surpassed objectives with outstanding ROI:
• Sales Growth: Significant uplift of 6.2% in UP and 4.9% in Maharashtra, indicating strong purchase intent.
• Exceptional ROAS: Achieved 2.3 in UP and 1.9 in Maharashtra, validating the digital approach's efficiency.
• Campaign Efficiencies: Realized 10% YouTube bid rate efficiencies through continuous optimization, maximizing media spend effectiveness.
• Unprecedented Reach: Attained 60% incremental reach at a 4+ frequency, successfully penetrating inaccessible segments and boosting critical mind metrics.
Dettol Original Soap solved a critical penetration challenge with the help of relevant data signals on YouTube, thereby setting a new benchmark for leveraging digital to drive significant, measurable success and ROI.
