Different funnel stages require different evaluation timelines and metrics. Understanding these differences prevents premature optimization and campaign killing.
Here's how to properly assess each funnel level:
π Give L2 campaigns 2-3 weeks for evaluation
Allow sufficient time for audience warming and data collection. Cut faster only if performance is clearly terrible within one week.
π Test L2 impact by pausing campaigns
Temporarily pause L2 to measure L3 performance impact. If L3 suffers, L2 was effectively feeding bottom-funnel conversions.
π Focus on total funnel ROAS over individual levels
Measure overall profitability across all campaign levels. Individual campaign ROAS matters less than total return on investment.
π Track L3 performance as funnel health indicator
L3 should deliver highest ROAS since audiences are most warmed. Poor L3 performance signals upstream funnel problems.
π Use different metrics for different objectives
L1: video views, CTR, CPC alongside ROAS.
L2: frequency, engagement, warming metrics.
L3: conversion rates and ROAS.
Most advertisers kill profitable campaigns too early because they don't understand funnel evaluation timelines. L2 campaigns need 2-3 weeks to show their true impact on L3 performance.
The key metric isn't individual campaign ROASβit's total funnel profitability. Patience pays in funnel marketing.
