What is a A/B Testing?

The mechanics are simple. Traffic is split between version A and version B, each visitor sees one, and you compare how many complete the action you care about. The discipline is in changing one meaningful thing at a time, deciding in advance what counts as success, and running the test long enough that the result is not just the noise of a quiet week.

A/B testing suits high-traffic pages far better than low-traffic ones. If a page receives a handful of visitors a week, the difference between two versions will be swamped by ordinary variation, and acting on the result is guesswork wearing a lab coat. Smaller sites usually get more from qualitative work: watching how people actually use the page, and reading what they ask before they buy.

That qualitative evidence is often easier to gather than a valid test. Chat transcripts from a Clerkzo widget show the exact questions visitors ask on each page, in their own words, which points at what to change long before you have the traffic to test it. Combined with a playground for trying new answers before they go live and a corrections loop for fixing what the assistant gets wrong, it gives smaller businesses a practical alternative to underpowered testing.
