A donor who cannot complete a gift form with a keyboard, a customer who cannot read a low-contrast service page, or a job seeker blocked by an unlabeled application field may never tell you what went wrong. They simply leave. A website accessibility compliance checklist helps organizations identify those barriers before they cost trust, engagement, revenue, or support for a mission.
For businesses, nonprofits, and community organizations, accessibility is not a cosmetic add-on after a website launch. It is part of creating a credible, high-performing digital presence that serves more people and supports measurable growth.
What Website Accessibility Compliance Means
Website accessibility means people with disabilities can perceive, understand, navigate, and interact with your website. This includes visitors who use screen readers, keyboard-only navigation, voice controls, magnification tools, captions, or other assistive technology.
In the United States, accessibility is often discussed in relation to the Americans with Disabilities Act, particularly for organizations serving the public. Requirements can vary by organization, sector, funding source, and jurisdiction, so this checklist is not legal advice. Still, the Web Content Accessibility Guidelines, commonly called WCAG, provide the most widely used technical framework for improving accessibility. For most public-facing organizations, WCAG 2.2 Level AA is a practical target.
The business case is equally clear. Accessible websites can improve usability for every visitor, strengthen brand trust, reduce friction in key conversion paths, and help organizations reach audiences that an inaccessible site excludes. A clear heading helps a screen reader user, but it also helps a busy visitor scan a page. Captions support deaf and hard-of-hearing viewers, while also helping people watch a video in a quiet office or crowded train.
Website Accessibility Compliance Checklist for Core Pages
Start with the pages where people take action: your homepage, contact page, service pages, donation or checkout flow, event registration, job application, and account portal. A beautiful homepage does not offset an inaccessible form that prevents someone from becoming a customer, donor, volunteer, or applicant.
Make every function usable by keyboard
A visitor should be able to use all interactive elements without a mouse. Use the Tab, Shift + Tab, Enter, and arrow keys to test menus, popups, forms, sliders, accordions, video controls, and checkout steps.
- Ensure keyboard focus moves in a logical order through the page.
- Make the focused item clearly visible with a strong outline or other visual indicator.
- Confirm users can open and close navigation menus, modal windows, and dropdowns with a keyboard.
- Avoid keyboard traps, where focus enters a component but cannot move out of it.
- Add a skip navigation link so keyboard users can bypass repeated menu items and move to main content.
Keyboard access is one of the fastest ways to expose hidden usability issues. If your team cannot reach or operate a feature with a keyboard, many visitors will not be able to either.
Build pages with meaningful structure
Screen reader users rely on page structure to understand content and move efficiently. Pages need a single, descriptive H1 heading, followed by headings that follow a logical order. Do not choose headings because they look visually appealing. Choose them because they describe the hierarchy of the content.
Use real lists for groups of related items, real buttons for actions, and real links for navigation. A clickable image or styled text block may look polished, but it can create confusion if the underlying code does not communicate its purpose.
Every page should also include a descriptive title in the browser tab. “Contact Nixie Tech” is useful. “Page 12” is not.
Add useful text alternatives for images
Images that communicate information need alternative text that explains their purpose. For example, an image showing a volunteer team packing food boxes could use alt text such as “Volunteers pack meal boxes at a Chicago community food drive.” The goal is not to describe every color or background detail. It is to provide the information a sighted visitor receives from the image.
Decorative images should be marked so assistive technology can ignore them. Complex visuals such as charts, maps, and infographics need a more complete text explanation nearby. If a chart makes the case for a program’s impact, its numbers and takeaway must be available in text, not only through color and shapes.
Check color, contrast, and visual clarity
Low contrast is one of the most common accessibility failures, particularly when brand colors are applied to small text, buttons, or form messages. As a general WCAG AA benchmark, normal text should have a contrast ratio of at least 4.5:1 against its background. Large text has a lower threshold, but relying on large text is rarely a complete answer.
Do not use color as the only way to communicate status or meaning. A required field cannot be marked only with red. A fundraising progress bar cannot rely only on green. Pair color with clear text, icons, patterns, or labels.
This is where thoughtful brand implementation matters. Accessibility does not require a generic-looking website. It requires a visual system that retains character while giving people enough contrast, legibility, and clarity to act with confidence.
Create accessible forms that people can finish
Forms are often where accessibility and conversion performance meet. Every input needs a visible label that remains available when a user begins typing. Placeholder text is not a substitute for a label because it can disappear and may have poor contrast.
Instructions should appear before the field they describe. Required fields should be clearly identified, and error messages must tell users what went wrong and how to fix it. “Invalid entry” is not enough. “Enter a valid email address, such as name@example.com” gives the visitor a next step.
Test forms for screen reader announcements, keyboard access, error handling, and confirmation messages. If a form times out, provide a warning and a way to extend the session. This is especially relevant for donation, registration, healthcare, financial, and application workflows.
Review Media, Documents, and Third-Party Tools
Accessibility gaps often come from assets or tools outside the main website template. A modern compliance review should include the full visitor journey, not just the pages your internal team edits most often.
Make video and audio content accessible
Videos need accurate captions that identify spoken content and meaningful sound. Auto-generated captions can be a useful starting point, but they frequently misidentify names, technical terms, and calls to action. Review and correct them before publishing.
When visuals communicate information that is not spoken, provide audio description or a meaningful text alternative. For audio-only content, offer a transcript. If your organization uses video for program stories, product education, or campaign promotion, this step protects both access and message clarity.
Audit PDFs and downloadable resources
An accessible website can still fail visitors if its essential information is stored in inaccessible PDFs. Annual reports, program applications, menus, brochures, policies, and board materials should be checked for tagged headings, logical reading order, selectable text, descriptive links, form labels, and sufficient contrast.
When possible, publish vital information as a web page as well as a download. Web pages are generally easier to update, search, translate, and use with assistive technology. PDFs may still have a role for formal documents or print-ready materials, but they should not become a barrier to a core service.
Test embedded platforms and plugins
Scheduling systems, donation tools, payment processors, chat widgets, maps, cookie banners, and social media feeds can all introduce accessibility issues. You may not control their source code, but you are still responsible for the experience your visitors receive.
Before selecting a vendor, ask about WCAG conformance, keyboard testing, screen reader support, and the availability of accessibility documentation. After installation, test the actual implementation on your site. A vendor’s claim is useful, but it does not replace real-world testing in your branded flow.
Combine Automated Scans With Human Testing
Automated accessibility tools are valuable for catching missing alt text, contrast problems, empty links, and other code-level issues at scale. They cannot reliably judge whether alt text is meaningful, heading order makes sense, a form is understandable, or a checkout path is frustrating.
Use automated scans as an early warning system, then conduct manual testing. Navigate key pages by keyboard. Test with at least one screen reader when possible. Zoom text to 200 percent and verify that content remains usable without horizontal scrolling on standard page layouts. Review mobile behavior, since accessibility problems often appear differently on smaller screens.
For a stronger review, involve people with disabilities in usability testing. Technical conformance and lived experience are related but not identical. A site may pass a scan yet still create needless work for the people it is meant to serve.
Turn Accessibility Into an Ongoing Operating Practice
Compliance is not a one-time launch task. Every new campaign page, product update, staff upload, PDF, video, plugin, and brand refresh can introduce new barriers. The most effective organizations create a simple governance process rather than waiting for a complaint or redesign.
Assign clear ownership across marketing, content, design, development, and operations. Give content editors practical standards for headings, links, image descriptions, and captions. Include accessibility checks in design review, quality assurance, procurement, and post-launch maintenance. For larger sites, schedule periodic audits that prioritize high-traffic and high-conversion pathways first.
The right investment depends on your site’s size, platform, audience, and risk profile. A small local business may begin by correcting core templates, forms, and color issues. A nonprofit serving vulnerable communities may need a broader review of multilingual content, program applications, PDFs, and donation systems. What matters is moving from good intentions to an accountable plan.
A more accessible website sends a practical message: every visitor’s time, independence, and participation matter. Start with the page where your audience most needs to act, fix the barriers that stand in their way, and let that standard guide every future digital decision.
