The results were promising almost immediately, and by the end of the test, we saw a 55% improvement in cost-per-lead over the previous period (from $8.22 to $3.67), and a 48% improvement in CPL in the 3 new ads compared to all other lead gen ads in the account, year-to-date. The new ads generated 118 leads in just over a month. We did also see a lift in their secondary KPI, CTR, compared to both YTD (+19%) and previous period (+48%).
