A website can look polished on a desktop and still frustrate customers on a phone. Responsive web design helps pages adapt to different screen sizes, but a quick resize is not enough to confirm the experience works. London businesses should test real customer tasks: finding a service, understanding the offer, and getting in touch. Use this checklist to review layouts, menus, text, and calls to action on phones, tablets, and desktop screens—and note where visitors may get stuck.
Check Layouts at Real Sizes
Open key pages on an actual phone, not just in a desktop browser preview. Check common tasks on both a smaller phone and a larger one, then repeat on a tablet and desktop. Look for horizontal scrolling, cut-off content, overlapping elements, and images that make important information hard to find.
Pay attention to how content changes order as the screen narrows. The main service, essential details, and next step should remain easy to spot. Images should fit their containers without distortion, while columns should stack in a sensible reading order. Test both portrait and landscape views if customers may use either orientation.
Test Navigation and Menus
Try to reach important pages using only the mobile menu. Labels should make sense without guesswork, and visitors should be able to open, close, and move through the menu using a finger. Check that the menu does not cover its own controls or leave the page in a confusing state after a selection.
Make sure key destinations are not buried. Services, contact details, and other high-priority pages should be reachable without excessive tapping. If the site has a long page, test whether in-page links or a clear back-to-top control help people move around. Also check that links and buttons have enough space between them to reduce accidental taps.
Review Readability and Content
Read each page on a phone at its normal zoom level. Body text should be comfortable to read, headings should make the page easy to scan, and line lengths should not force visitors to work through dense blocks. Check contrast between text and background, especially for small labels, footnotes, and text placed over images.
Confirm that important information remains visible when content wraps. Buttons should not split awkwardly, headings should not collide with nearby elements, and forms should show complete labels and instructions. Trim repeated or low-priority copy if it pushes the main message too far down the page, but keep the details customers need to make a decision.
Verify Key Actions and Forms
Test every important action on each screen size: call, email, request a quote, book, or submit a form. Confirm that phone numbers open the dialer on mobile and email links open a mail app where supported. Buttons should be easy to find and tap, and their wording should explain what happens next.
Complete forms with a phone keyboard. Check that fields are clearly labeled, the right keyboard appears for details such as email addresses, and error messages explain how to fix a problem. Submit the form and confirm that the success message is visible. If a sticky button or banner is used, make sure it does not cover form fields or other essential content.
Review your most visited pages first, then test the full journey from arriving on the site to completing a key action. Record issues with a screenshot and the device or screen size where they appear, so fixes are easy to prioritize.
