How to Test Your Site’s Accessibility with Free Tools
An accessible website gives more people a fair chance to find information, complete tasks and contact an organisation. Accessibility testing can reveal barriers affecting keyboard users, people with low vision, screen-reader users, people with hearing loss and anyone navigating on a small or slow device. You do not need an expensive testing suite to begin.
A useful process combines automated scans, manual checks and feedback from people with different access needs. For an Australian website serving visitors in Sydney, Melbourne, Brisbane or regional communities, this approach also helps identify issues caused by mobile layouts, inconsistent internet connections and unfamiliar local language.
Why Accessibility Testing Matters
Accessibility is broader than adding alternative text to images. Visitors may need clear focus indicators, meaningful headings, sufficient colour contrast, captions, predictable navigation and form instructions that explain errors in plain language. A site can pass an automated scan while still being confusing to someone using a keyboard or screen reader.
Australian organisations should treat accessibility as part of responsible digital publishing. The Disability Discrimination Act 1992 is relevant to equal access, while the Web Content Accessibility Guidelines provide a practical technical framework. Testing against WCAG 2.2 at an appropriate level can help teams identify risks, although compliance decisions may require professional legal or accessibility advice.
Accessibility also supports everyday usability. A commuter checking a service on a phone in Melbourne, a customer using browser zoom in Adelaide or someone in regional Queensland dealing with a slower connection can benefit from the same improvements made for disabled users.
Begin With Free Automated Scanners
Automated tools are a fast way to find common problems. Google Lighthouse, available through Chrome DevTools, reports on performance and accessibility, while WAVE identifies issues directly on a rendered page. The free axe DevTools browser extension checks for many WCAG-related problems and explains why a particular element may fail.
Run a scan on representative pages rather than the home page alone. Include a landing page, article, contact form, search results page and any screen that requires sign-in. A clean result on one template does not prove that every page is accessible, especially when content editors can introduce new headings, links or images.
Treat automated results as evidence, not a final verdict. Tools can usually detect missing labels, low contrast or invalid ARIA patterns, but they cannot reliably judge whether alternative text is useful or whether a multi-step process makes sense. Review each warning, remove false positives carefully and record the decisions in an issue tracker.
Test Navigation Without A Mouse
Keyboard testing is free and exposes barriers quickly. Use Tab to move through interactive elements, Shift+Tab to move backwards, Enter or Space to activate controls, and the arrow keys where appropriate. Check whether the focus order follows the visual order and whether a visible focus ring remains easy to locate.
A visitor should be able to reach menus, pop-ups, forms, carousels and media controls without getting trapped. When a dialogue opens, focus should move into it and return sensibly when it closes. Skip links can help keyboard users bypass repeated navigation, particularly on content-heavy sites with long pages.
Try the site with a screen reader as well. NVDA is a free option for Windows, while VoiceOver is built into Apple devices and TalkBack is available on Android. Listen to headings, landmarks, link names, button labels and form errors. “Click here” and “Read more” provide little context when announced out of visual context, whereas descriptive labels explain the destination.
Inspect Content, Colour And Visual Structure
A page should remain understandable when text is enlarged to 200 percent and when content reflows on a narrow screen. Check for clipped text, overlapping controls, horizontal scrolling and menus that disappear when browser zoom is used. Chrome and Firefox include zoom controls, and browser extensions can simulate some visual conditions.
Free contrast checkers such as WebAIM’s Contrast Checker can assess text and background colour combinations. Normal text generally needs a contrast ratio of at least 4.5:1 under WCAG AA, while large text has a lower threshold. Colour must not be the only way to communicate status: pair a red error message with an icon or clear wording.
Images need purposeful alternative text. A product or editorial image may need a concise description, while a decorative shape should usually have empty alternative text so assistive technology ignores it. For examples of how digital presentation can be organised visually, the SpeedTao gallery offers a useful reference point, although every image still needs context-specific review.
Check Mobile And Local Use Cases
Test on a real phone as well as a desktop browser. Australian audiences often access content over mobile data, during commutes or from locations where a stable broadband connection is not guaranteed. Try common viewport sizes and rotate the device. Buttons should be comfortably spaced, sticky elements should not cover content, and essential tasks should work without delicate gestures.
Performance and accessibility overlap. Large images, autoplay video and excessive scripts can make a page difficult to use for people on limited data plans or older devices. Compress media, provide captions and transcripts, defer non-essential code and ensure the core content appears before decorative features load.
Use Australian English and familiar local conventions where they suit the audience. Dates, phone numbers, addresses and currency should be presented consistently, and location fields should accommodate states and territories rather than assuming an overseas format. Test contact and delivery forms with suburbs in Perth, Canberra or Hobart as well as metropolitan examples, since validation rules can accidentally reject legitimate Australian details.
Combine Technical Checks With Human Review
Inspect the page structure in browser developer tools. Headings should follow a logical hierarchy, landmark regions should be meaningful, and interactive controls should use native HTML where possible. Native buttons, links and form elements generally provide more reliable keyboard and assistive technology behaviour than custom elements built entirely with scripts.
Review dynamic content carefully. Error messages, cookie notices, filters and loading states must be announced or made discoverable when they change. If a site uses server-side rendering or static generation, the rendering method can influence how quickly content and metadata become available; this rendering comparison provides useful context when evaluating technical architecture alongside user experience.
Human feedback remains essential. Invite people who use screen readers, magnification, switch access or speech input to complete realistic tasks, and compensate them for their time. Ask them to search, submit a form, recover from an error and locate contact details. Their observations often reveal friction that no scanner can identify.
Create A Practical Testing Routine
Make accessibility part of the publishing cycle instead of treating it as a one-off audit. Scan new templates before release, manually test important user journeys and repeat checks after major changes to navigation, forms, design systems or third-party components. Keep screenshots and issue records so developers can verify fixes rather than relying on memory.
Prioritise barriers by impact and frequency. A missing label on every search field may deserve attention before a minor heading inconsistency on a rarely visited page. Fix the underlying component where possible, then test several pages to confirm that the repair has spread throughout the site.
A simple routine can keep a small team consistent:
- Run Lighthouse, WAVE or axe on key page templates after each significant release.
- Complete a keyboard-only journey through navigation, search, forms and media controls.
- Test zoom, reflow, contrast and text alternatives on desktop and mobile.
- Use NVDA, VoiceOver or TalkBack for realistic tasks, not just a quick page scan.
- Record failures, assign owners and retest every fix before closing the issue.
