Key Performance Indicators (KPIs) for Mid-Level Marketing Managers to Measure Multi-Channel Digital Campaign Success

In multi-channel digital marketing, selecting the right KPIs is essential for mid-level marketing managers to measure and optimize campaign effectiveness across platforms like social media, email, paid search, SEO, and content marketing. The following KPIs focus on actionable insights that directly correlate with campaign goals including ROI, engagement, conversion, and customer retention.

1. Overall Campaign KPIs

These KPIs offer a comprehensive view of multi-channel campaign success and help prioritize resource allocation and strategic adjustments.

a. Return on Investment (ROI)

ROI evaluates campaign profitability by comparing revenue generated against spend. Monitoring ROI across channels ensures budget is focused on high-performing tactics.
Formula: ROI = ((Revenue - Campaign Cost) / Campaign Cost) * 100

CAC measures the average cost to acquire a new customer from all channel efforts. Segmenting CAC by channel uncovers the most cost-effective acquisition sources.
Formula: CAC = Total Campaign Cost / Number of Customers Acquired

Formula: Conversion Rate = (Conversions / Total Visitors) * 100
