What is 4DX?
Creating 2 versions of a digital asset to see which one users respond to better. Examples of
assets include a landing page, display ad, marketing email, and social post. In an A/B test,
half of your audience automatically receives “version A” and half receives “version B.” The
performance of each version is based on conversion rate goals such as the percentage of
people
who click on a link, complete a form, or make a purchase.
