Define the broken transition precisely
'The CTA does not work' can mean low discovery, low activation, repeated activation, destination loss, task failure, wrong-fit action, or downstream regret. Record the page state, eligible audience, device, control label, placement, destination, and time window. Confirm event instrumentation before interpreting a rate. Then list rival failure classes: the action is irrelevant, its consequence is unclear, it is hard to find or operate, the technical transition fails, or the promise produces poor fit. A visible button cannot repair a missing decision reason, and a click cannot prove a successful handoff.

Relevance failure appears before the control
Inspect whether the reader has the information and intent needed for the proposed action. An early purchase prompt may be noticed and correctly ignored because price, evidence, or fit remains unresolved. Compare behavior across entry questions and content depth, then ask representative readers what they would need next. Do not label a lower action rate as failure when the page enables informed refusal. NICE guidance to consider reading path and limit the strongest CTA helps frame the check, but only reader research can establish whether this control matches the decision stage.

Prediction failure hides behind generic text
Ask users to predict the destination, commitment, data sharing, cost, and ability to return before activation. W3C link-purpose guidance requires determinable purpose from text or programmatic context and explains the value of meaningful text for link-list and keyboard navigation. Repeated 'Learn more,' 'Continue,' or 'Get started' labels can lead to different states while sounding identical. Check the accessible name as well as visible text. A change is warranted when plausible readers consistently expect a different consequence, not merely because the copy team prefers another verb.

Operation failure needs path reproduction
Test keyboard, touch, zoom, small viewports, high latency, disabled scripts where the service supports them, and representative assistive technology. Look for obscured controls, invisible focus, overlapping sticky elements, tiny targets, duplicate submissions, lost state, and external redirects that fail or cannot return. Use native semantics and verify announced role and name. The U.S. Web Design System provides component-level accessibility test guidance; a passing automated scan is only one input. Reproduce actual task paths because a control can be technically present while unreachable in the reader's order of operation.

Handoff failure is measured after activation
Reconcile click, destination arrival, state confirmation, form progress, error, completion, support, cancellation, and refund where data and privacy boundaries allow. For an affiliate link, check that the destination still matches the surrounding description and that a reader can return; do not promise merchant availability. A spike in clicks with a fall in qualified completion suggests the new prominence may have recruited unready readers. A flat click rate with fewer errors may still be an improvement. Maintain guardrails for user control, disclosure visibility, accessibility, and downstream fit instead of optimizing a single activation event.

Repair the supported class, not every surface
If relevance is weak, add or relocate decision evidence. If prediction is weak, rewrite the label and context. If discoverability is weak, repair hierarchy and reading order. If operation fails, fix semantics or implementation. If post-click fit is poor, qualify the action or repair the destination promise. Change one mechanism at a time when feasible and state the stopping rule. Preserve a control-path recording or annotated reproduction so reviewers can verify that the proposed mechanism actually occurred. Do not run a button-color test while destination loss is unresolved. Recheck the smallest high-risk path after the fix instead of assuming a passing component demo repairs the complete journey. Archive the hypothesis tree, evidence, change, and reversal trigger so a temporary metric shift does not become permanent mythology.
