Optimizing lead generation in Europe — efficiency through exclusion.
Client overview
A lead-generation program in Europe was spending on broad audiences with generic messaging and an ad frequency above 30. Zali Digital rebuilt targeting, added mid-funnel nurture and controlled frequency on Meta Ads across €18,842.29 of spend.
The challenge
Budget was leaking in five places:
Targeting issues. Spend went to broad and irrelevant audience segments.
Generic ad copy. Messaging failed to resonate, lowering engagement and CTR.
High frequency. Audience overlap pushed frequency above 30, causing ad fatigue.
No mid-funnel strategy. Interested prospects were not nurtured, so conversions were missed.
Slow optimization. Campaigns were not adjusted in real time.
Business objectives
Lower the cost of each completed registration.
Reach high-intent prospects and exclude the rest.
Stop ad fatigue from eroding results.
Strategy & execution
Focus on high-intent users; exclude irrelevant segments.
