Website Accessibility: 6 Checks Every Design Must Pass [Checklist]

Website accessibility is no longer an optional nicety tucked into the last phase of a project. It is a foundational business requirement that determines whether a meaningful portion of your audience can actually use what you have built. Think of it this way: if your storefront had steps but no ramp, you would lose customers before they even reached the door. A website with poor accessibility does the exact same thing, quietly, to millions of users with visual, motor, auditory, or cognitive differences. This checklist walks you through six checks every design must pass, so your business does not accidentally lock out the people you are trying to serve.
A Strategic Cpluz Perspective
Most agencies treat accessibility as a compliance checkbox, something bolted on right before launch to avoid legal risk. We think that framing is backwards. At Cpluz, we apply what we call the A-U-X Model: Accessible, Usable, eXcellent. The principle is simple - accessibility should raise the baseline of usability for everyone, not just satisfy an audit.
Here is the counter-intuitive part: when we redesigned the approach for our retail clients, we discovered that accessibility fixes often improved conversion rates for users with no disabilities at all. Larger touch targets helped people on the move. Clearer contrast helped people browsing in bright sunlight. Captioned videos helped people watching without sound on public transit. Accessibility, in other words, is rarely a niche concern. It is a stress test that reveals friction points in your entire user experience. Treat it as a strategic lens for refining your design, not a legal formality you tolerate.
What Makes a Website Truly Accessible?
A truly accessible website allows every visitor, regardless of ability, to perceive, navigate, and interact with your content without unnecessary barriers. This means text that screen readers can interpret, colors that remain legible for people with low vision, and interfaces that respond to keyboards as reliably as they do to a mouse. Achieving this requires deliberate checks built into your design process, not an afterthought squeezed in before deployment.
Check 1: Color Contrast and Visual Clarity
Text must remain readable against its background for users with low vision or color blindness. A common hurdle we help startups in Tamil Nadu overcome is low-contrast branding choices that look elegant on a designer's monitor but disappear for a meaningful slice of real users. Run every text and background combination through a contrast checker, and pay particular attention to buttons and form labels, where poor contrast directly costs you conversions.
Check 2: Keyboard Navigation
Every interactive element - links, buttons, menus, forms - must be operable using only a keyboard. Many users with motor impairments, and a surprising number of power users, never touch a mouse. Tab through your entire site and confirm the focus order is logical and visible.
Check 3: Alt Text and Semantic Markup
Images, icons, and non-text content need descriptive alt attributes so screen readers can convey their meaning. Beyond alt text, your HTML structure itself matters: proper heading hierarchy and semantic tags give assistive technology a map of your page.
Check 4: Captioning and Media Alternatives
Video and audio content must include captions or transcripts. A mistake we often see businesses in the tech sector make is publishing polished product demo videos with no captions at all, effectively excluding deaf and hard-of-hearing prospects from a key piece of marketing.
Why Do So Many Websites Fail Accessibility Checks?
Most websites fail accessibility checks because teams treat accessibility as a final audit step rather than a design principle woven into every decision. In our work with fintech clients at Cpluz, we've found that retrofitting accessibility after launch costs significantly more time and money than building it in from the wireframe stage.
We once worked through a hypothetical scenario with a client whose e-commerce checkout flow relied entirely on color to indicate errors - a red border with no text label. Users with color blindness had no idea a field had failed validation, and cart abandonment on that step was noticeably high. The lesson here is not just about color; it is about never relying on a single sensory cue to communicate essential information. Redundancy in your feedback design protects a wider range of users and, often, reduces support tickets from everyone else too.
Common Accessibility Mistakes to Avoid
- Relying solely on color to convey meaning or status
- Skipping heading levels (jumping from an H1 straight to an H4)
- Auto-playing media without an obvious pause control
- Using placeholder text as the only label for form fields
- Ignoring mobile screen reader behavior during testing
How Do You Test a Website for Accessibility?
You test accessibility through a combination of automated scanning tools and genuine manual review, since automated tools alone catch only a fraction of real issues. Run your pages through a scanner to flag obvious problems like missing alt text or insufficient contrast. Then complement that with manual keyboard navigation, screen reader testing, and, where possible, feedback from actual users with disabilities.
Check 5: Responsive and Zoomable Design
Your layout must remain functional and readable when users zoom in up to 200 percent or resize their browser window. Text should reflow rather than becoming clipped or overlapping other elements.
Check 6: Clear, Consistent Navigation
Navigation menus, search functions, and page structure should behave predictably across every page. Users with cognitive disabilities, in particular, benefit enormously from consistency, since unpredictable layouts increase mental load and abandonment.
Frequently Asked Questions
Q: Is website accessibility a legal requirement in India?
A: Regulatory expectations around digital accessibility are tightening globally, and Indian businesses serving international markets or government contracts increasingly need to meet recognized accessibility standards to remain competitive and compliant.
Q: Does improving accessibility slow down my website?
A: No, accessibility improvements like semantic markup and proper alt text typically have negligible or even positive effects on load speed and SEO performance.
Q: Can I check accessibility without hiring a specialist?
A: Yes, founders can start with free automated scanning tools and manual keyboard testing, though a comprehensive audit benefits from a partner experienced in inclusive design.
Q: How often should accessibility checks happen?
A: Accessibility should be reviewed at every major design or content update, not just once at launch, since new features can quietly introduce new barriers.
