Website accessibility is no longer a niche concern reserved for government portals or large enterprises. Every business with a website has visitors who rely on screen readers, keyboard navigation, or high-contrast display settings to browse effectively. If your site creates barriers for these users, you are not just risking compliance issues - you are turning away potential customers before they even see what you offer.
Think of your website as a physical storefront. You would never install a locked door with no ramp and call it welcoming. Yet that is precisely what an inaccessible website does to millions of users daily. This checklist walks you through four foundational WCAG (Web Content Accessibility Guidelines) checks your business needs to run today, along with the reasoning behind each one.
A Strategic Cpluz Perspective
Most accessibility checklists treat compliance as the finish line. We see it differently. In our work with clients across retail and fintech at Cpluz, we've found that businesses treating accessibility as a pure legal checkbox tend to produce clunky retrofits - alt text stuffed in as an afterthought, awkward keyboard traps, color contrast fixes that clash with brand identity.
Our approach instead uses what we call the A-R-C framework: Audit, Remediate, Culture. Audit means running structured technical checks against WCAG success criteria. Remediate means fixing issues within your existing design system rather than bolting on patches. Culture means training your internal content and design teams so new accessibility debt doesn't accumulate with every future page you publish.
This third pillar is the one most agencies skip entirely. A mistake we often see businesses in the tech sector make is fixing accessibility once during a redesign, then quietly reintroducing violations six months later when a marketing team uploads a new landing page without alt text or proper heading structure. Building accessibility into your content workflow, not just your codebase, is what keeps your site compliant long after the audit report is filed away.
What Are the Core WCAG Checks Your Site Needs?
The four checks below cover the areas where most business websites fail, based on the patterns we consistently encounter during audits.
1. Is Your Color Contrast Sufficient?
Text and background color combinations must meet a minimum contrast ratio so users with low vision or color blindness can read your content. WCAG AA standard requires a 4.5:1 ratio for normal text and 3:1 for large text.
A mistake we often see businesses in the tech sector make is choosing a pale gray for body copy because it looks elegant in a design mockup. It looks elegant until a user with even mild vision impairment cannot read your pricing page. Run your color palette through a contrast checker before finalizing any brand style guide.
2. Can Every Function Be Operated by Keyboard Alone?
Every interactive element - menus, forms, buttons, modals - must be fully operable without a mouse. Many users with motor impairments navigate exclusively via keyboard, and screen reader users depend on logical tab order to move through a page.
When we redesigned the navigation approach for one of our retail clients, we discovered that the dropdown menu worked perfectly with a mouse but trapped keyboard users inside an infinite loop with no visible exit. The lesson here is simple: a feature that looks flawless visually can still be functionally broken for a significant slice of your audience. Test your site by unplugging your mouse and navigating using only Tab, Shift+Tab, and Enter.
3. Does Every Image Have Meaningful Alt Text?
Alt text describes images to users relying on screen readers, and it also helps search engines understand your visual content. Decorative images should carry empty alt attributes so screen readers skip them, while informative images need concise, accurate descriptions.
A common hurdle we help startups in Tamil Nadu overcome is treating alt text as an SEO keyword-stuffing opportunity rather than a genuine description. Write alt text the way you would describe the image to someone on a phone call - clearly and without exaggeration.
4. Is Your Page Structure Built with Proper Headings?
Screen reader users often navigate a page by jumping between headings rather than reading top to bottom. If your headings skip levels, or if you use bold text instead of actual heading tags for visual emphasis, you break that navigation path entirely.
Here is a quick checklist to verify your heading structure:
- Only one
<h1>per page, matching the page's primary topic - Headings follow a logical order without skipping levels (h2 before h3, not h2 straight to h4)
- Headings describe the content of the section that follows, not just a styling choice
- No heading tags used purely for making text larger or bolder
What Are the Most Common Accessibility Objections We Hear?
Business owners often push back on accessibility work, assuming it is costly or purely a legal exercise. Our team's analysis of dozens of client audits revealed that most fixes are inexpensive when addressed at the design system level rather than page by page. A robust accessible foundation actually reduces long-term maintenance costs, since consistent components need to be fixed once rather than repeatedly across every new page.
Does accessibility slow down your development timeline? Not when it is built into your design tokens and component library from the outset. Retrofitting is what costs time and money - building it in from day one does not.
Frequently Asked Questions
Q: Is WCAG compliance legally required for my business?
A: Requirements vary by jurisdiction and industry, but many countries now treat inaccessible websites as a legal risk under broader anti-discrimination or consumer protection laws, so proactive compliance is a sound strategic choice regardless of your specific obligations.
Q: How often should I audit my website for accessibility?
A: A full audit annually is a reasonable baseline, paired with lighter checks after every major redesign or content migration to catch new issues before they accumulate.
Q: Does improving accessibility also help my SEO?
A: Yes, many accessibility improvements such as proper heading structure, descriptive alt text, and clean semantic markup directly align with what search engines use to understand and rank your content.
Q: Can I fix accessibility issues without a complete website redesign?
A: In most cases yes, since color contrast, alt text, heading structure, and keyboard navigation can typically be remediated within your existing design framework without a full rebuild.
