The Role In The Customer Journey
Ab Testing should be treated as part of a larger customer journey rather than an isolated tactic. Define what happens immediately before it, the single primary job it performs, and the next step a successful visitor should take.
Common Implementation Mistakes
Common problems come from unclear objectives, too many competing actions, missing message continuity between steps, and adding complexity before the basic path works. Test the experience as a customer would: use a mobile device, submit the form, complete the transaction where relevant, and verify the promised next step actually occurs.
What To Measure
Choose a metric tied to the component's job. A landing page may be judged by qualified form submissions, a checkout by completed purchases and abandonment, an upsell by acceptance and incremental order value, and an automation by whether the intended contacts receive the correct next action. Measurement should reveal where to investigate, not merely produce a dashboard.
