In digital marketing, assumptions can be expensive. What you think will work may not always resonate with your audience. This is where A/B testing (also called split testing) becomes essential. It allows marketers to compare two versions of a campaign element and identify which one performs better based on real user behavior.
From ads and landing pages to emails and social media posts, A/B testing helps optimize performance, reduce costs, and improve ROI. Below are practical and high-impact A/B testing ideas you can apply to your digital campaigns.
