A/B tests on call-to-action buttons, links, and conversion triggers. See which CTA patterns drive more clicks and conversions.
This segment contains 2 cta experiment records. Winner, loser, mixed, and inconclusive are reported outcome labels. Check each evidence badge before treating a result as independently reviewable.
Use these records as hypothesis input, then match the audience, metric, treatment, and context before planning a local test. Reported lifts are not pooled because the underlying outcomes and designs may not be comparable.
Button engagement alone does not show whether the element helped conversion. The topline movement was small and uncertain, while the diagnostic path exposed a larger problem: only about six of every hundred button interactions reached the next funnel stage. The label appears to have attracted people looking for account access rather than shopping, and an added modal inserted another step before the destination. Some activity also shifted away from stronger existing paths. For global navigation changes, evaluate downstream completion by origin page and intent; raw click volume can reward the wrong behavior.
Sticky mobile CTAs can compress time-on-page meaningfully (~15% faster) without sacrificing engagement signals — users converted at a directionally higher rate AND moved through the page faster, suggesting reduced hesitation rather than rushed clicks. The result was shipped via 90/10 holdout monitoring rather than traditional 50/50 A/B inference — the high baseline (~85%) and limited mobile traffic made full A/B underpowered, so the team chose a holdout-validated rollout as the deliberate methodology. Bayesian P(variant > control) was ~0.90, supporting the directional ship call.
