Click-through rate compares a defined recipient group with recorded clicks after a campaign. The figure can be useful, but it becomes misleading when the basis, measurement method or purpose is unclear.
Define the denominator
Decide whether you are comparing clicks with messages sent, accepted or delivered, and use the same definition over time. Remove test numbers and technical duplicates before drawing conclusions.
Put the click in context
A click is an action, not necessarily a purchase or completed task. Combine campaign tagging with landing-page data to see how many people completed the next relevant step.
Respect privacy
Explain link tracking and use the data only for purposes supported by a valid lawful basis. Avoid personal data in URLs and do not retain details longer than necessary.
Compare groups with care
Different audiences, offers and times create different conditions. Prefer comparisons between campaigns with similar purposes and record what changed. A higher click result is not necessarily better when more people opt out, the landing page fails or the resulting actions have little value.
Define the need before tracking
Describe which decision the click data should support, who needs access and how long details should be retained. If aggregated campaign figures are sufficient, recipient-level information need not be preserved. Data minimisation makes both the analysis and the privacy explanation easier.
A relevant next step

Plan recipients, wording, timing and follow-up as one coherent journey.
