Landing page design — Define what the checklist must approve
Sign-off scope identifies the campaign promise, supported devices, form boundary and tracking events under review.
Landing page design — Confirm inputs and source material
Final copy, legal language, destination URLs and analytics definitions enter as owned source material.
Landing page design — Cover formats, widths and contexts
Breakpoint evidence uses realistic text length, translation and imagery rather than tidy placeholder content.
Landing page design — Exercise states and exceptions
Form testing covers focus, completion, validation, delay, duplicate submission, recovery and confirmed success.
Landing page design — Check accessibility and traceability
Keyboard order, visible focus, contrast, error guidance and event provenance stay in the same acceptance record.
Landing page design — Name the acceptance owner
The acceptance owner can explain the consequence of a failure and authorise a documented exception.
Landing page design — Create the sign-off record
The final record attaches a source, observed result, owner and retest condition to every accepted check.
Practical checklist
- Check content hierarchy at narrow, medium and wide widths using final-length headings and labels.
- Specify default, focus, filled, invalid, submitting, success and recovery states for every form.
- Verify the keyboard sequence, visible focus, labels, error guidance and contrast without relying on colour alone.
- Map each primary and secondary action to a destination, event name and expected confirmation state.
- Run a content and interaction review with realistic campaign parameters, slow responses and duplicate submission attempts.
