To reduce the eCPL (effective cost per lead) for native ads, start by refining your targeting. Focus on reaching the most relevant audience for your offer. Use compelling headlines and visuals to improve click-through rates. Test multiple ad creatives to find the best-performing ones. Optimize your landing page for conversions by making it user-friendly and clear. Track your campaigns and analyze performance data to identify areas for improvement. Adjust bids and budgets to focus on high-performing placements. Use retargeting to re-engage interested users. By continuously testing and optimizing, you can lower eCPL while improving campaign results.
