Testing What Converts
Hypotheses and metrics.
Why Test At All
Opinions about what converts are often wrong. Testing replaces guessing with evidence by comparing versions of a page against real visitor behavior.
Conversion rate optimization, or CRO, is the disciplined practice of running these tests to steadily improve results instead of redesigning on a hunch.
What an A/B Test Is
An A/B test shows version A to half your visitors and version B to the other half, then measures which converts better.
Because traffic is split randomly and at the same time, outside factors affect both versions equally. The difference in conversion rate points to the change you made.
A/B test setup:
Control (A): current headline
Variant (B): new headline
50% of visitors see A
50% see B
