Website Design Checklist: 40 Checks for Conversion-Focused Pages

If you need a practical website design checklist, use this page to review what users see and click first: hierarchy, spacing, CTAs, trust blocks, and form clarity.

Start with a page-level scan in Website Design Audit. If the issue is flow-level friction (not visual design), run Website UX Audit.

What this page covers

This checklist focuses on design execution on live pages:

visual hierarchy
readability and spacing
CTA and interaction clarity
trust placement near decisions
mobile-first layout quality

For navigation architecture, use Website Navigation Best Practices. For usability testing scripts and question banks, use How to Conduct Usability Testing.

40-point website design checklist

1) Above-the-fold clarity

[ ] Headline states who the page is for and the core outcome.
[ ] Subheading removes the biggest objection in one sentence.
[ ] Primary CTA is visible without scrolling on desktop and mobile.
[ ] Hero image supports the message (not decorative noise).
[ ] One primary goal exists for the page.

2) Visual hierarchy and readability

[ ] H1, H2, and body type sizes create a clear scan path.
[ ] Body line length is readable (no long wall-of-text columns).
[ ] Section spacing follows a consistent rhythm.
[ ] Color contrast supports readability in all key blocks.
[ ] Important content appears above less-critical content.

3) CTA and interaction design

[ ] Primary CTA copy is action-specific (not vague).
[ ] Secondary CTA does not compete visually with the primary.
[ ] Button styles are consistent across templates.
[ ] Hover/focus/active states are visible and predictable.
[ ] CTA placement aligns with decision moments (after proof, before exit).

4) Trust and decision support

[ ] Testimonials are specific and near high-intent CTA sections.
[ ] Case-study links are easy to find from sales pages.
[ ] Pricing context is clear before form submission.
[ ] Guarantees/policies are linked near commitment points.
[ ] Contact/help path is visible when users hesitate.

5) Forms and conversion components

[ ] Forms request only essential information.
[ ] Labels are explicit and examples are provided where needed.
[ ] Inline validation explains how to fix each error.
[ ] Multi-step forms show progress and expected effort.
[ ] Success states explain what happens next.

6) Mobile-first design QA

[ ] Tap targets are usable with one thumb.
[ ] Sticky elements do not hide CTA or form fields.
[ ] Font sizes stay readable without zoom.
[ ] Layout remains stable while media loads.
[ ] Mobile CTA path has no dead-end steps.

7) System consistency

[ ] Card, button, and input patterns match the design system.
[ ] Icon style and stroke weight are consistent.
[ ] Heading capitalization rules are consistent.
[ ] Reusable sections use the same spacing and alignment tokens.
[ ] Legacy page styles were not mixed into new templates.

8) Performance and accessibility design checks

[ ] Images are compressed to match rendered dimensions.
[ ] Decorative media does not delay first meaningful content.
[ ] Focus order follows visual order.
[ ] Color is not the only indicator for state and status.
[ ] Motion effects can be disabled and do not block interaction.

Monthly: full template family sweep.
Quarterly: redesign debt review and style-system cleanup.

30-minute website design review workflow

Pick one conversion page and define one primary action.
Run the 40-point checklist and score each item quickly.
Flag every 0 as immediate fix candidates.
Group issues by effort (quick wins vs structural fixes).
Ship top 3 fixes first.
Re-check conversion rate and click depth after 7 to 14 days.

If landing pages are the main issue, combine this with Landing Page Anatomy, Landing Page Best Practices, and Landing Page Copywriting.

Use each page for a distinct intent:

This page (website design checklist): visual and interface design quality.
