10 Common Website Design Mistakes and How to Fix Them
Ten website design mistakes that cost enquiries on business, school and church sites, with a clear fix for each and a short audit you can run today.
Practical tips for mobile friendly website design: layout, readable text, tap targets, menus, forms, images and how to test on real phones.
For most Indian small businesses, schools and churches, the typical visitor holds a phone. They may be on a modest handset, on a mobile connection that fluctuates, and often in a hurry. Google also uses the mobile version of your pages for indexing, so a weak mobile site affects how you are found as well as how you convert.
Mobile friendly website design is not about shrinking the desktop site. It means planning the page for a small screen and a thumb, then adding to it for larger screens. These tips cover layout, text, buttons, menus, forms, images and testing.
Mobile first design means you decide what a phone visitor needs most before thinking about wide screens. A small screen forces useful discipline: what is the one message, and what is the one action?
For a school, that may be "admissions open for next year" plus a button to call the office. For a plumber, it is the service area and a tap-to-call button. Once the phone version works, you can add more detail and imagery for larger screens, rather than cutting things away from a crowded desktop design.
A responsive website adjusts its layout to the screen width. The usual pattern is a multi-column grid on desktop that becomes two columns on a tablet and one column on a phone.
Aim for body text of at least 16 pixels, comfortable line spacing and strong contrast between text and background. Light grey text on white looks elegant on a design file and is hard to read in sunlight.
Keep paragraphs to two or three lines on a phone, use clear subheadings, and put the key point first. If you write for Tamil or other regional languages as well as English, test the fonts on real devices. Some fonts render poorly on older Android phones, and Tamil script often needs a little more line height than English.
Fingers are less precise than a mouse. Buttons and links need enough size and spacing so a thumb does not hit the wrong one. A common guideline from design systems is a touch target of around 44 to 48 pixels, with space between neighbours. Accessibility guidance sets a lower minimum, but larger is kinder on small screens.
Tip: Put the main action where a thumb reaches easily. For many local businesses that is a tap-to-call or WhatsApp button, either in the header or fixed at the bottom of the screen. Make sure it does not cover the content or the cookie notice.
| Element | Good practice on mobile |
|---|---|
| Phone number | Tappable link that starts a call |
| Button that opens a chat with a short pre-filled message | |
| Address | Link that opens the map app |
| Tappable link, but offer a form as the main option |
A menu button that opens a clear list is the standard, and visitors understand it. Keep the top level short, group related pages and make the close button obvious. Test that the menu opens and closes reliably on every page, and that sub-menus can be opened with a tap, since there is no hover on a phone.
Avoid putting every page into the menu. If a page is not something a visitor will look for, link it from the footer or from relevant content instead.
Forms are where mobile visitors most often give up. Ask only for what you need. Name, phone number and a short message are enough for most enquiries.
Mobile connections vary, and many users have limited data. Resize images to the size shown, compress them and use modern formats such as WebP where your platform supports it. Load images below the first screen only when needed, and avoid autoplay video and heavy animation.
Speed is part of mobile design, not a separate task. Google publishes Core Web Vitals targets for loading, responsiveness and visual stability, and you can check them in PageSpeed Insights. Our website speed checklist walks through the fixes, and a hosting plan that suits your site removes a common bottleneck.
Browser tools that simulate a phone are useful, but they do not show everything. A real handset shows problems with scrolling, keyboards, fonts and touch behaviour.
Note: Your own analytics show how many visitors use phones. Check the device report in Google Analytics 4 and design for the split you actually have.
Features that help people with disabilities also help everyone using a phone in bright sun, on a bus or with one hand. Good contrast, resizable text, clear focus states for keyboards and descriptive link text all make a page easier to use.
These small habits also reduce support calls, because visitors can complete the task without needing to phone and ask.
Responsive describes the technique: one site whose layout adapts to the screen size. Mobile friendly describes the result: a site that is easy to read and use on a phone. A responsive site can still be unfriendly if the text is tiny or the buttons are cramped.
Open it on a real phone and try the main journey. Then run the page through PageSpeed Insights and check the mobile experience in Google Search Console. Look for horizontal scrolling, text that is too small and buttons that are too close together.
For most businesses, no. One responsive website that works well on all screen sizes is easier to maintain and better for search. An app only makes sense when you need features a website cannot provide.
Google uses the mobile version of a page for indexing, and page experience is one of many signals. A site that is hard to use on a phone is likely to lose visitors even if it ranks, so treat it as a conversion issue first.
Good mobile friendly website design is mostly discipline: one column, readable text, easy taps, simple menus and quick pages. If your current site struggles on phones, start by testing the main journey on a real handset.
