The internet should be a place where everyone can access information, use online services, and interact with businesses independently. Yet many websites still create unnecessary barriers for people with disabilities. Small issues such as poor color contrast, inaccessible forms, confusing navigation, and missing image descriptions can make essential online tasks difficult or impossible.
Web accessibility is the practice of designing and developing websites, applications, and digital tools so that people with different abilities can use them effectively. It supports people with visual, hearing, motor, and cognitive disabilities while also improving usability for a much wider audience.
For businesses, accessibility is more than a design consideration. It can influence customer experience, website usability, brand reputation, and legal risk. In this guide, we’ll explain the fundamentals of web accessibility, the standards businesses should understand, common website and content management system (CMS) challenges, and practical steps for creating a more inclusive digital experience.
What Is Web Accessibility?
Web accessibility means removing barriers that prevent people from perceiving, understanding, navigating, or interacting with digital content.
An accessible website considers how people use assistive technologies, including screen readers, screen magnifiers, voice recognition software, and alternative input devices. It also supports visitors who navigate with a keyboard instead of a mouse.
Examples of accessible website features include:
- Descriptive alternative text for meaningful images.
- Clear headings and logical page structure.
- Sufficient color contrast between text and backgrounds.
- Keyboard-accessible menus, buttons, and forms.
- Captions or transcripts for relevant audio and video content.
- Form labels and error messages that assistive technologies can identify.
- Clear, readable language and predictable navigation.
Accessibility should be considered throughout the design, development, content creation, and maintenance process—not added as a last-minute adjustment.
Understanding Web Accessibility Standards
Accessibility standards help organizations identify barriers and establish measurable goals. Several acronyms appear frequently in accessibility discussions, but each serves a different purpose.
Web Content Accessibility Guidelines (WCAG)
The Web Content Accessibility Guidelines, developed by the World Wide Web Consortium (W3C), are a widely used international standard for digital accessibility.
WCAG organizes accessibility around four principles:
- Perceivable: Users must be able to access information through their available senses.
- Operable: Navigation and interactive features must be usable through appropriate input methods.
- Understandable: Content and interface behavior should be clear and predictable.
- Robust: Content should work reliably with browsers and assistive technologies.
WCAG includes three conformance levels: A, AA, and AAA. Level AA is a common target for accessibility programs, although the appropriate requirements depend on the applicable law, contract, and organizational needs.
Businesses should review the current WCAG standards and guidance when planning accessibility improvements.
ATAG, UAAG, and WAI-ARIA
Other accessibility resources address different parts of the digital experience:
- Authoring Tool Accessibility Guidelines (ATAG): Address the accessibility of tools used to create web content, as well as the accessibility of the content those tools produce.
- User Agent Accessibility Guidelines (UAAG): Address accessibility considerations for browsers and other user agents.
- WAI-ARIA: Provides semantics that can help assistive technologies interpret certain interactive web components when native HTML does not provide the necessary information.
These resources are particularly relevant to teams building complex web applications, publishing systems, and custom content management platforms.
Why Web Accessibility Matters for Businesses
Investing in accessibility can benefit both website visitors and the organizations serving them.
1. Create a Better User Experience
Accessible design often makes websites easier for everyone to use. Clear navigation, readable typography, descriptive buttons, consistent page layouts, and helpful form instructions reduce confusion and make important tasks easier to complete.
For example, a clearly labeled contact form benefits visitors using screen readers as well as people accessing the website on a small screen or in a hurry.
2. Reach a Broader Audience
When a website is difficult to navigate or interact with, potential customers may leave before finding the information they need.
Accessibility improvements help reduce avoidable barriers and make services available to a wider range of users. This is especially important for businesses that rely on online bookings, ecommerce transactions, customer portals, applications, or digital support.
3. Support SEO and Content Discoverability
Accessibility and search engine optimization share several useful practices. Descriptive headings, meaningful link text, image alternatives, logical HTML structure, and text-based content can help users navigate pages and help search engines interpret content.
However, accessibility improvements do not automatically increase rankings, and accessibility alone is not a guarantee of SEO success. It should be part of a broader strategy that includes useful content, technical SEO, performance, and a strong user experience.
Google provides additional recommendations in its SEO guide for web developers.
4. Reduce Avoidable Legal and Reputational Risks
Inaccessible digital services can expose organizations to complaints, legal disputes, and reputational damage, depending on the applicable requirements and circumstances.
Proactively reviewing accessibility can help businesses identify and address problems before they become more serious. It is important to remember, however, that automated scans and individual fixes cannot independently establish full legal compliance.
5. Demonstrate a Commitment to Inclusion
An accessible website communicates that a business considers the needs of different customers and employees.
That commitment should extend beyond the public website to online applications, employee portals, internal documentation, and the tools people use to create and manage digital content.
Common Web Accessibility Challenges
Even organizations that value accessibility may struggle to implement it consistently. Some issues originate in the design, while others are introduced through code, third-party tools, or everyday content updates.
Low Color Contrast and Difficult-to-Read Text
Text that blends into its background can be difficult to read for people with low vision or color vision deficiencies. Small font sizes, tightly spaced content, and instructions that rely on color alone can create additional barriers.
Designers should check contrast, use readable typography, and communicate important information through more than color alone.
Inaccessible Navigation and Interactive Elements
Dropdown menus, pop-ups, sliders, tabs, and custom buttons may not work correctly with a keyboard or assistive technology.
Every interactive control should have a clear purpose, an accessible name, and a predictable interaction pattern. Keyboard users should be able to reach controls, understand which element has focus, and operate the available features.
Missing Image Alternatives and Media Captions
Meaningful images need appropriate alternative text so that their purpose or information can be conveyed to people who cannot see them. Decorative images can often use empty alternative text so screen readers do not announce unnecessary details.
Videos may require captions, and audio content may need transcripts. The right approach depends on the content and the needs it must support.
Inaccessible Forms and Error Messages
Forms are especially important because they often support conversions and essential tasks. If a visitor cannot identify a field, understand its requirements, or discover why an error occurred, they may be unable to submit the form.
Use programmatically associated labels, clear instructions, accessible validation messages, and helpful error recovery. Do not communicate errors through color alone.
Third-Party Plugins and Custom Components
Embedded booking systems, chat widgets, maps, payment tools, and other third-party components can introduce accessibility barriers that website owners cannot resolve through their own page styling alone.
Review these components during procurement and testing. Where a component is inaccessible, work with the vendor or consider an accessible alternative.
Why Content Management System Accessibility Matters
A content management system is the operational foundation of many websites. It allows employees to create pages, publish articles, upload images, manage forms, and maintain digital information.
An accessible public website is important, but the administrative interface matters too. If employees with disabilities cannot use the CMS independently, they may encounter barriers when carrying out everyday responsibilities.
An accessible CMS should consider:
- Keyboard navigation: Can users perform common publishing tasks without a mouse?
- Screen reader compatibility: Are controls, menus, fields, and status messages announced meaningfully?
- Clear forms and controls: Do fields have labels, instructions, and understandable error messages?
- Accessible content creation: Does the editor help authors create meaningful headings, links, tables, and image descriptions?
- Consistent workflows: Can employees complete tasks without confusing or unexpected interface changes?
- Accessible output: Does the CMS generate pages that visitors can use with assistive technologies?
Accessibility should be evaluated across both the authoring interface and the website it produces.
A Practical Approach to Accessible CMS Development
Consider an organization that needs a content management platform for employees with different accessibility needs. The platform must support accessible public pages while allowing staff to create and maintain content independently.
A successful implementation begins by understanding the people who will use the system and the tasks they need to perform. Designers and developers can then evaluate the existing interface, document barriers, and prioritize improvements.
For a custom CMS built with a framework such as CakePHP, accessibility work may involve improving semantic HTML, implementing keyboard-friendly controls, providing accessible validation messages, and ensuring that interactive components communicate correctly with assistive technologies.
The technology itself does not guarantee accessibility. The outcome depends on implementation, content, integrations, and ongoing testing.
A structured development process should include:
- User and task research: Identify who will use the system and which workflows are essential.
- Accessibility requirements: Establish measurable criteria based on relevant standards and user needs.
- Accessible design: Create consistent layouts, readable interfaces, and understandable interaction patterns.
- Development and integration: Implement semantic markup and accessible controls, including third-party components.
- Testing and remediation: Combine automated checks with manual keyboard testing, screen reader evaluation, and feedback from people with disabilities.
- Training and maintenance: Help content editors understand accessibility and review the system as it changes.
This process makes accessibility part of the platform’s architecture and everyday operation rather than a separate, one-time task.
How to Make Your Website More Accessible
Businesses do not need to fix every issue in a single day. A prioritized plan can help teams make steady, measurable progress.
Step 1: Conduct an Accessibility Audit
Review important pages and workflows, including the homepage, navigation, service pages, contact forms, account areas, and checkout process where applicable.
Automated testing tools can identify some issues, but they cannot reliably detect every accessibility barrier. Manual evaluation is essential.
Step 2: Test Keyboard Navigation
Navigate the website without a mouse. Confirm that links, menus, dialogs, form fields, and buttons can be reached and used. Make sure keyboard focus is visible and does not become trapped in an interface component.
Step 3: Review Content and Structure
Use logical heading levels, descriptive links, meaningful page titles, and appropriate image alternatives. Check that instructions are understandable and that tables are structured correctly when tables are necessary.
Step 4: Check Visual Accessibility
Evaluate text contrast, zoom and reflow behavior, text spacing, focus indicators, and the visibility of important controls. Test the website on different screen sizes and with browser accessibility settings where relevant.
Step 5: Test Forms and Interactive Components
Check required fields, validation, error announcements, keyboard behavior, and accessible names. Review pop-ups, sliders, accordions, and third-party integrations separately.
Step 6: Include People with Disabilities in Testing
Automated tools and expert reviews are valuable, but feedback from people who use assistive technologies can reveal practical barriers that other methods miss.
Step 7: Establish an Ongoing Accessibility Process
Assign responsibility for accessibility, train content editors, test major updates, and include accessibility requirements when selecting new themes, plugins, and software.
For a practical starting point, explore the W3C WCAG overview and its supporting evaluation resources.
Common Accessibility Mistakes to Avoid
Some approaches appear to solve accessibility problems but leave important barriers in place.
- Relying only on automated scans: Tools identify many common issues, but manual testing is still necessary.
- Treating an accessibility overlay as a complete solution: A widget cannot automatically correct every underlying design, code, or content problem.
- Adding generic alt text everywhere: Alternative text should communicate the purpose of meaningful images, not repeat filenames or add unnecessary descriptions.
- Ignoring the CMS: Accessible public pages do not guarantee that employees can use the administrative interface.
- Treating accessibility as a one-time project: New content, updates, plugins, and redesigns can introduce fresh barriers.
- Assuming accessibility guarantees SEO gains or legal compliance: Accessibility supports better usability, but rankings and compliance depend on many factors and the applicable requirements.
