The Ultimate Guide to Key Performance Indicators for Evaluating Marketing Campaigns Managed by Agency Owners
1. Understanding the Importance of KPIs to Evaluate Marketing Campaign Effectiveness
When you hire an agency to manage your marketing campaigns, precisely tracking key performance indicators (KPIs) is essential to evaluate campaign effectiveness. KPIs provide objective, data-driven insights enabling you to measure how well your marketing dollars translate into business outcomes. By aligning KPIs with your business goals, you can verify whether the agency’s work is delivering tangible results and identify areas for optimization.
