Best Practices (what to check)
Responsiveness isn’t just “fit the screen”. It’s making sure your hero message is clear, your CTA is reachable, and nothing breaks on real device sizes. Use these checks to catch issues fast.
Mobile clarity
CTA above the fold, readable headings, no clipped cards, no horizontal scroll. Buttons must be thumb-friendly.
Desktop consistency
Check spacing rhythm, typography scale, multi-column grids, and that hero + services sections feel premium.
Conversion checks
Forms must be easy. Primary CTA should be obvious. Navigation should never hide key actions.
