How to test a website before launch: guide and checklist
Why Test Your Website
Before Launch
Even a perfectly designed website can “break” in small ways — a non-working button, a broken link, an unsubmitted form. The user won’t investigate and will simply close the tab.
Testing helps catch in advance everything that could go wrong:
- bugs and layout errors;
- broken links and redirects;
- display issues on different devices;
- slow page loading;
- malfunctioning forms and buttons;
- content inaccuracies and SEO settings issues.
The earlier a mistake is found — the cheaper it is to fix.
What Needs
To Be Tested on a Website
Even with perfect development, errors almost always occur: non-working forms, incorrect links, typos. So we check everything — from buttons to counters — and sleep peacefully.
Technical Part
Errors in basic functionality are the most common and, unfortunately, critical. They may not be visible at first glance,
but they can ruin conversion rates.
What We Check:
- forms — submission and validation;
- buttons — work and lead where they should;
- redirects — not to 404;
- 404 — page exists, no broken links;
- speed — how it loads on mobile.
UX/UI
The interface should be clear, elements should not overlap when
the screen size changes. This directly affects behavioral factors and conversion. When a user gets lost on the site, they usually leave.
