What is A/B testing?

A/B testing is a marketing optimization technique used to compare two versions of an advertisement, landing page, headline, image, or other marketing element to determine which performs better.

In Reddit advertising, A/B testing helps marketers identify which ad creatives, headlines, audiences, and calls-to-action generate better engagement and conversions.

How does A/B testing work?

1. Create two versions: Prepare Version A and Version B of an advertisement.

2. Choose an element: Test headlines, images, videos, CTAs, or landing pages.

3. Divide the audience: Show each version to comparable audience groups.

4. Run the experiment: Collect performance data over a suitable period.

5. Compare results: Evaluate clicks, engagement, conversions, and other metrics.

6. Choose the winner: Use the version that performs better based on your objective.
