Beta Hub: +3,000 teens enrolled in science and technology, with -50% CPA

The challenge

With more than 60 courses available and simultaneous operations in Argentina, Mexico, and Brazil, the program needed to turn genuine interest among young people into concrete enrollments at a cost that could hold up as the campaign matured.

• Reaching a narrow age segment (16 to 18) across three countries with different advertising markets and digital consumption behaviors.
• Maintaining message consistency across more than 60 courses with varying subjects and demand levels.
• Reducing cost per enrollment consistently over the first six months of the campaign without sacrificing volume.

Our approach

We worked on Beta Hub's paid media accounts around three priorities: targeting the right audience, organizing the course catalog efficiently, and optimizing cost per enrollment on an ongoing basis.

1. 01

   Market-level and age-specific segmentation

   We structured campaigns separately for Argentina, Mexico, and Brazil, adapting audiences and bids to each market's conditions. Targeting was focused exclusively on the 16-to-18 age range, with interest signals in education, technology, and science.

2. 02

   Managing a broad course catalog

   With more than 60 courses to promote, we organized the inventory into campaign groups by thematic affinity and historical demand. This allowed us to allocate budget where conversion was most efficient and avoid cannibalization between similar creatives.

3. 03

   Sustained CPA optimization

   Over the first six months we adjusted bids, creatives, and audience criteria based on accumulated enrollment data. The result was a 50% reduction in cost per enrollment while maintaining a total enrollment volume that exceeded 3,000 young people.
