Every AI marketing investment needs a measurement framework. Here's what to track:

Efficiency Metrics

• Content pieces produced per week (before vs after AI)
• Time to publish per content type
• Cost per piece of content
• Ad creative variants tested per month

Performance Metrics

• Organic traffic growth rate
• Email open and click rates
• Ad CTR and conversion rate
• Cost per lead and customer acquisition cost

Bottom Line Metric

Marketing-attributed revenue per marketing dollar spent. AI should move this number up — if it isn't, adjust how you're using it.
