====== Why short-term tests punish long-term offers ======

===== The speed bias =====

Modern marketing favors speed.

Quick tests.
Fast decisions.
Immediate ROAS validation.

Short-term data feels safer because it arrives quickly.

Long-term offers suffer under this model.

CBSplit was built to correct this imbalance.

===== Long-term offers reveal value slowly =====

Some offers are structured around:

  
  * Subscription continuity
  * Gradual value delivery
  * Education-driven retention
  * Ongoing engagement

Their strength appears over time.

Short test windows only capture the first transaction.

They ignore lifecycle durability.

===== Early metrics undervalue alignment =====

Long-term offers rely on:

  
  * Clear expectation setting
  * Honest billing transparency
  * Sustainable positioning
  * Trust-based messaging

These traits may produce:

  
  * Slightly lower initial conversions
  * More cautious buyers
  * Slower front-end growth

Short-term tests penalize these traits.

CBSplit evaluates the full lifecycle.

===== Impulse offers win early =====

Short-term testing often rewards:

  
  * Urgency-heavy copy
  * Emotional triggers
  * High-pressure angles
  * Aggressive upsell stacking

These tactics increase immediate revenue.

They often reduce:

  
  * Retention
  * Refund resistance
  * Subscription survival

Short-term tests confuse intensity with durability.

===== Rebill cycles change the winner =====

Long-term offers often:

  
  * Rebill consistently
  * Maintain lower churn
  * Produce stable cohorts
  * Generate predictable LTV

Short-term tests conclude before rebills occur.

CBSplit extends evaluation beyond the initial billing cycle.

===== Refund timing masks durability =====

Long-term offers may show:

  
  * Slightly higher early hesitation
  * Slower revenue ramp
  * Lower impulse conversion

But they may also show:

  
  * Lower refund rates
  * Fewer chargebacks
  * Stronger subscription alignment

Short-term tests ignore delayed refund stabilization.

CBSplit integrates refund-adjusted performance.

===== Acquisition cost is not the only variable =====

Short-term tests often optimize for:

  
  * Lower CPA
  * Faster breakeven
  * Immediate ROAS

Long-term offers optimize for:

  
  * Higher LTV
  * Reduced churn
  * Stable processor health
  * Sustainable growth

Short-term focus punishes long-term economics.

===== Scaling decisions depend on evaluation horizon =====

When offers are evaluated too quickly:

  
  * Durable offers are paused
  * Fragile offers are scaled
  * Risk accumulates
  * Margin erodes later

CBSplit aligns scaling decisions with lifecycle truth.
