Which tools can be used for A/B testing on ads?

• A. Facebook Ads Manager
• B. LinkedIn Campaign Manager
• C. Twitter Ads
• D. Google Ads and Google Optimize

Answer: (D)

A/B testing ads means comparing two variants to see which performs better, using controlled experiments to attribute differences to the change being tested. The best pairing for this in a Google-focused workflow is Google Ads together with Google Optimize. Google Ads lets you run ad experiments or create ad variations to test different headlines, images, calls to action, or final URLs, so you can directly measure which ad version drives better clicks and engagement. Google Optimize complements this by letting you run A/B tests on the landing pages users reach after clicking an ad, measuring which page variant converts at a higher rate or leads to better post-click outcomes. Using both tools gives a complete picture: optimize the ad itself for engagement and optimize the landing experience for conversions, providing actionable insights across the entire funnel. While other platforms like Facebook or LinkedIn offer their own split-testing capabilities, the combination of Google Ads and Google Optimize is a standard, integrated approach for testing both ad creativity and landing-page performance.
