Test broadly so every visitor gets a good experience.
- Different browsers: view your site in Chrome, Firefox, Safari, and Edge — rendering can differ.
- Different devices: check on a phone, tablet, and desktop to confirm it's responsive.
- Built-in tools: use your browser's developer tools (device toolbar) to simulate various screen sizes.
- Online testers: services like BrowserStack let you preview your site on many real devices and browsers.
- Check key actions on each — menus, forms, and the checkout — not just the homepage.
Tip: Most visitors are on mobile, so always confirm your site looks and works well on a phone first.
