Ad Copy Performance Benchmarks
AI vs. Human Ad Copy: Head-to-Head Results
In controlled A/B tests across 10,000+ ad groups, AI-generated copy (using AdsMG AI) vs. human-written copy showed:
| Metric | Human Copy | AI Copy | Difference |
|---|---|---|---|
| Average CTR | 2.14% | 5.07% | +137% |
| Average Conversion Rate | 4.8% | 7.2% | +50% |
| Average Quality Score | 6.1/10 | 8.4/10 | +38% |

How to Use These Benchmarks
For campaign planning: Use industry CPA and CPL benchmarks to set realistic initial targets. Assume a 4–8 week learning period before AI optimization reaches full performance.
For budget forecasting: Apply ROAS benchmarks to your average order/contract value to calculate the ad spend required to hit revenue targets.
For internal reporting: Compare your current CPA/ROAS against industry benchmarks to contextualize performance for stakeholders unfamiliar with advertising norms.
For platform selection: Industries with high purchase intent (emergency services, insurance, legal) see the strongest Google Search performance. Industries with visual products (fashion, food, home goods) see stronger Meta performance.
