Cross-Channel Performance Analysis

When each channel reports independently — Google Ads showing ROAS of 8x, Meta showing ROAS of 5x, email showing CPA of $12 — the numbers appear impressive in isolation but may be significantly overstated because each channel claims credit for the same conversions.

Cross-channel analysis recognizes that customers interact with multiple channels before converting, and that optimizing each channel independently without understanding their interactions produces a fragmented, potentially conflicting strategy.

Cross-channel KPIs measure business outcomes rather than channel-specific metrics: total new customers acquired (not new customers by channel), total revenue from marketing, blended CAC across all channels, and LTV/CAC ratio.

Blended metrics force conversations about the full marketing investment — including brand spend that does not show direct attributable conversions — rather than cherry-picking the channels that look best in their own reporting.
