A/B testing helps businesses identify the most effective ad elements, improve campaign performance, and maximise return on ad spend (ROAS).

What are the key variables businesses can test in A/B testing?

Answer 3

• Creative (image, video, ad copy).
  
  • Audience (different targeting criteria).
  • Placement (where the ad appears).
  • Delivery optimisation (goal setting for conversions, clicks, etc.).
  • Call-to-action (CTA) (e.g., “Shop Now” vs. “Learn More”).

A holdout test measures the true impact of an ad campaign by comparing people who saw the ad vs. those who didn’t, helping to measure incremental lift.
