Usability Testing Checklist: What to Test Before Your Website Goes Live

Launching a website without usability testing is risky. This comprehensive pre-launch checklist covers visual hierarchy, navigation, forms, mobile experience, performance, and SEO—so you can catch costly mistakes before going live.

February 20, 2026

You’re about to launch. The design is finished. The content is uploaded. The developers say everything works.

Time to go live?

Not yet.

Every website launch carries risk. Broken forms, confusing navigation, invisible CTAs, slow loading, mobile layout issues — these problems are often invisible to the team that built the page but immediately obvious to first-time visitors.

This checklist is your safety net. Run through it before every launch — whether it’s a full website, a landing page, or a major update. It takes less than an hour and can prevent weeks of lost conversions.
