To achieve a substantial 35.75% reduction in Cost per Acquisition (CPA), we implemented a series of data-driven optimizations.
First, we refined the audience by reducing the number of interests, expanding the age range from 24 to 55, and extending the location radius to 35 miles.
Additionally, we enhanced remarketing efforts by adjusting lists to 180 days across Facebook, Instagram, and website engagers, ensuring we re-engaged high-value prospects.
These strategic adjustments allowed for more effective targeting, improved reach, and stable campaign performance — all while lowering acquisition costs.
