// Example: Test pricing pages
const pricingVariants = {
  control: {
    starter: 29,
    pro: 99,
    business: 299
  },
  test: {
    starter: 39,
    pro: 129,
    business: 349
  }
}

// Show different prices to 50% of visitors
const variant = Math.random() < 0.5 ? 'control' : 'test'

// Track which converts better
analytics.track('pricing_page_viewed', {
  variant: variant,
  prices: pricingVariants[variant]
})

Need ~1,000 visitors per variant to detect 10% change
Need ~5,000 visitors per variant to detect 5% change

  - Existing: Stay at $99 for 1 year, then $129
  - New: Pay $129/mo immediately
  - Pros: Balanced approach
  - Cons: Still have to communicate increase

Option 3: No grandfathering, small increase
