A person looking for housing advice, addiction support or a vital health service may reach your website at the hardest point in their week. If they cannot use the menu with a keyboard, understand a form, read the text on a phone or complete a referral, the barrier is not technical. It has a human consequence. Website accessibility testing is how organisations find and remove those barriers before people are excluded.
For charities, public bodies and mission-led organisations, accessibility is not a finishing touch for a new website. It is part of delivering your service fairly, protecting your reputation and making every pound invested in communications work harder. A site that works for more people can generate more enquiries, referrals, donations, event bookings and meaningful engagement.
What website accessibility testing actually involves
Accessibility testing checks whether people with different access needs can perceive, understand, navigate and use a website. That includes people who are blind or partially sighted, Deaf or hard of hearing, neurodivergent, have a learning disability, experience limited mobility, or use assistive technology such as screen readers, voice control and keyboard navigation.
It also helps people whose circumstances change from moment to moment: someone using a cracked phone screen, reading in bright sunlight, holding a baby, coping with fatigue, or trying to complete a form on a slow connection. Accessible design is not a niche feature. It is clearer, more resilient digital communication.
Testing should look beyond whether a page technically loads. It asks practical questions: can somebody find the service they need? Do headings explain what follows? Does error messaging tell people how to fix a form? Can a screen reader make sense of a donation journey? Are videos understandable without sound?
In the UK, public sector bodies have specific accessibility regulations for websites and mobile applications, including requirements to publish an accessibility statement. Many charities and other organisations are not covered by those regulations in the same way, but the Equality Act 2010 still matters. More importantly, the people you exist to support should not have to work harder to access help.
Why automated checks are useful, but not enough
Automated tools are a sensible starting point. They can quickly identify missing image descriptions, poor colour contrast, empty links, incorrectly structured headings and some coding errors. Used regularly, they are a useful safety net, particularly when content is being updated by busy teams.
But a tool cannot reliably tell you whether alternative text is meaningful, whether a page makes sense when read aloud, or whether a call to action is clear to a first-time visitor. It may confirm that an image has alternative text, while missing the fact that the text says only “image”. It may also flag issues that need human judgement rather than a blanket fix.
Manual testing fills that gap. An experienced tester will navigate with only a keyboard, check focus order, assess form labels and error messages, review page structure, test zoom and reflow, and listen to key journeys through a screen reader. They will look at the language and interaction design, not simply the code.
The most revealing insight often comes from involving disabled people and people with lived experience of the service area. A technically compliant website can still be confusing, emotionally overwhelming or impractical for its intended audience. User testing shows where real life does not match an internal assumption.
Prioritise the journeys that matter most
A full website audit can be valuable, especially after a redesign or when a site has grown over several years. However, small teams do not always have the budget or capacity to fix everything at once. The right approach depends on the scale of the site, the risks involved and the services it supports.
Start with the journeys where failure carries the greatest cost. For many organisations, that means finding contact details, making a referral, requesting support, booking training, donating, joining as a member, reporting an issue or accessing urgent information. Test these routes across desktop and mobile, from the first search result or social post through to confirmation.
It is also worth reviewing your most visited pages and your most recently published content. An inaccessible campaign page can limit the reach of a message at exactly the point you have invested time and budget in getting it seen. A downloadable PDF may contain essential eligibility criteria but be unreadable to someone using a screen reader.
A clear audit should separate critical barriers from lower-priority improvements. If a keyboard user cannot submit a safeguarding concern, that needs urgent attention. If a decorative element needs a minor code adjustment, it should be scheduled, but it should not delay a vital fix. Good website accessibility testing gives teams a practical route forward rather than an intimidating list of faults.
Common barriers with real consequences
Some issues appear repeatedly because they are easy to create during design, content entry or platform updates. The following are especially worth checking across priority journeys:
- Colour used as the only way to communicate meaning, such as red text for an error or green text for success.
- Low-contrast text, particularly on coloured campaign graphics, image overlays and button states.
- Missing, vague or misleading alternative text for images, charts and linked graphics.
- Forms with unclear labels, placeholder text used as a label, or errors that do not explain what needs changing.
- Menus, pop-ups and buttons that cannot be reached or operated with a keyboard.
- Heading structures that skip levels or use bold styling in place of meaningful headings.
- Video without captions, and audio or visual content without an equivalent explanation where one is needed.
- PDFs created as scanned images, leaving people unable to select, enlarge or have the content read aloud.
These are not merely compliance issues. Poor contrast can hide an appointment link. A badly labelled form can stop someone asking for help. An inaccessible document can exclude a member from information they are entitled to receive.
Build accessibility into everyday publishing
The least expensive accessibility issue is the one prevented before publication. That means making accessible practice part of how your team briefs, writes, designs and signs off content, rather than relying on a rescue operation after launch.
Content editors need straightforward guidance: use descriptive headings, write purposeful link text, add meaningful image descriptions, avoid putting essential words into graphics, and create documents with proper structure. Designers need to consider contrast, text size, focus states and interaction from the earliest concepts. Developers need accessible components that remain usable when reused across the site.
WordPress can support accessible publishing well, but the theme, plugins, page builder choices and content habits all affect the outcome. A visually polished template is not automatically accessible. Equally, a well-built site can become harder to use if new content is added without care. Regular checks are part of responsible maintenance.
For public sector organisations, maintain the accessibility statement as the site changes and be honest about any known limitations. For every organisation, provide a clear way for people to report a problem or request information in a different format. The response matters as much as the wording: somebody should own the process and be able to act on it.
Turn findings into a workable improvement plan
A useful accessibility report should explain the issue in plain English, identify who may be affected, show where it occurs and recommend a proportionate fix. It should also distinguish between quick content changes, design-system improvements and development work that needs planning.
Avoid treating an audit as a one-off certificate. Websites change, browsers change, plugins update and new campaigns introduce new content patterns. A practical rhythm might include checks during design and development, testing before a major launch, routine reviews of high-priority pages, and a more thorough audit after significant changes.
The goal is progress that can be sustained by the people responsible for the site. That may mean fixing critical barriers first, training editors, improving templates, then scheduling deeper work into a wider redevelopment plan. For organisations under pressure, this is often more effective than promising perfection and delivering little.
Accessibility is one of the clearest ways a website can demonstrate that your organisation means what it says about inclusion. When people can find, understand and use your services without unnecessary obstacles, your digital presence does more than meet a standard. It makes room for people to take the next step when they need you.
