Litmus vs landing page A/B testing

A/B testing optimizes an existing funnel. Litmus answers the earlier question: should this idea, audience, promise, or offer exist at all?

QuestionLanding page A/B testingLitmus
Best used whenYou already have traffic and a page worth optimizing.You need to prove demand before building or launching.
Primary variablePage layout, copy, CTA, form length, or conversion flow.Audience, promise, offer, acquisition angle, and intent action.
Traffic sourceOften existing traffic or paid campaigns configured elsewhere.Acquisition is part of the experiment design, so the source and message are tied to the hypothesis.
Success metricConversion rate lift on the page.Qualified demand signal, confidence, skew, and cost per intent.
DecisionPick the higher-converting variant.Build, kill, iterate, or scale the idea.
Where each fits

Optimization is not validation

A/B testing is powerful once you know the market wants what you are offering. But it can make a weak idea look better by improving the wrapper around it.

Demand validation comes first. It tests whether the idea earns enough meaningful action from the right people to justify the next investment.

Simple rule

Validate before you optimize.

If the question is "which page converts better?", use A/B testing. If the question is "is this worth building?", use Litmus.
