Website Accessibility: 7 Practical Improvements Every Developer Should Make

Website accessibility is an important part of modern web development. A website should be usable by people with different abilities, devices, and ways of interacting with digital content.

Accessibility improvements can also make websites easier to navigate and understand for all users. Developers do not always need a complete redesign to get started. Small, thoughtful changes can make a meaningful difference.

Here are seven practical improvements to consider in your next web project.

1. Use Semantic HTML

Semantic HTML gives elements meaning. Instead of using

elements for every part of a page, choose elements such as , , , , and where appropriate.

For example:

<a href="/">Home</a>
<a href="/services">Services</a>

Our Services

Explore the services available to your business.

A meaningful document structure helps assistive technologies interpret the page and makes the code easier to maintain.

1. Add Alternative Text to Images

Images that communicate useful information should have descriptive alternative text. This helps users who rely on screen readers understand the image's purpose.

<img
src="team-meeting.jpg"
alt="A project team reviewing a website design"

Avoid stuffing keywords into alt text. Describe the image in context and keep the wording natural.

For purely decorative images, use an empty alternative attribute:

This allows screen readers to skip images that do not add meaningful information.

1. Make Keyboard Navigation Work

Not everyone uses a mouse. Some users navigate websites with a keyboard, so interactive elements must be reachable and usable without one.

Use native buttons and links instead of clickable generic elements wherever possible.

Open menu

Make sure the keyboard focus indicator remains visible. Avoid removing browser focus outlines unless you replace them with an equally clear indicator.

Test the page using the Tab, Shift + Tab, Enter, and Space keys.

1. Check Colour Contrast

Text should be easy to read against its background. Light grey text on a white background may look subtle, but it can be difficult for many users to see.

The WCAG 2.2 guidelines generally recommend a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text at Level AA.

Use a contrast-checking tool when choosing colours. Also, do not communicate important information through colour alone. For example, show an error message with clear text rather than relying only on a red border.

1. Build Accessible Forms

Forms should clearly identify what information users need to provide.

Use visible labels, suitable input types, and helpful error messages.

Email address
<input
type="email"
id="email"
name="email"
autocomplete="email"
required

Placeholder text should not replace a proper label. When validation fails, explain what went wrong and how to fix it.

For complex forms, ensure that error messages are associated with the relevant fields and that users can easily find them.

1. Use Headings in a Logical Order

Headings help users scan content and understand how different sections relate to each other.

Use one clear main heading for the page, followed by suitable subheadings. Do not select heading levels only because of their visual size; use CSS to control appearance.

For example:

h1 for the main page topic

h2 for major sections

h3 for subsections within those sections

A clear heading structure improves content organisation and makes long pages easier to navigate.

1. Test Accessibility Before Launch

Automated accessibility tools can identify common issues, but they cannot detect every usability problem.

Combine automated checks with manual testing. Navigate the website using a keyboard, zoom the page, inspect form errors, and test important journeys with a screen reader when possible.

Check menus, dialogs, forms, and other interactive components carefully. Fix critical issues before launch and include accessibility checks in your regular development workflow.

Accessibility and Website Performance Go Together

Accessible websites need more than correct HTML. They also benefit from clear content, responsive layouts, predictable navigation, and reliable performance.

These elements influence how people experience a website. Businesses working on their broader website experience can also explore iBirds Digital for information about its digital marketing services.

Conclusion

Website accessibility should be considered throughout development, not added as a last-minute task. Semantic HTML, descriptive image text, keyboard support, readable colours, accessible forms, logical headings, and regular testing provide a practical starting point.

Make these checks part of your development process. They can help you build websites that are more inclusive, easier to use, and better structured for everyone.
