The document describes a campaign to recruit 5,000 participants for Scholio within three weeks that initially failed to meet its goals. It outlines various target audiences that were planned to engage but problems surfaced. The campaign pivoted to test different messages, imagery and motivations through Facebook ads. This improved conversion rates from 5% to over 10% but was still too slow. Further testing of audiences, messages and motivations increased conversion rates to over 40% and recruitment goals were met. Lessons learned include questioning plans and stakeholders, using split testing capabilities, and working with experienced Facebook ad specialists.
