Challenge
Adbloom primary obstacle was balancing volume with strict compliance. Toluna required users to not only sign up but also verify their email addresses (DOI) to count as a conversion. Additionally, targeting was strictly limited to US residents over 18. Generating massive traffic is common, but driving traffic that completes a high-friction DOI process while maintaining user intent and quality is a significant hurdle.
Solution
Adbloom executed a targeted acquisition strategy for Toluna’s "Influencer" proposition, reaching US audiences 18+ with a rewards and community focus. Publishers highlighted earning incentives and driving impact, attracting users with genuine intent. Campaign compliance was strictly monitored, and traffic was optimized in real-time to prioritize verified, active respondents.
Results
Adbloom overcame high-friction conversion challenges, driving a surge of verified panelists actively participating in Toluna’s surveys and rewards. By focusing on users motivated by rewards and community, we achieved conversion rates that defied typical Double-Opt-In drop-offs.

Micro-communities
Survey and earning communities provided members who understand panel mechanics, converting to active, verified panelists at scale.
Mobile networks
Rewards app placements delivered volume with built-in intent, fueling 155K+ verified US panelists without sacrificing quality.
