Web Accessibility: 4 Errors That Are Blocking Your Users

Web accessibility is not a checkbox you tick after launch - it is a foundational principle of good design. Yet across countless audits, we keep encountering the same handful of errors, quietly turning away visitors who simply cannot use the site in front of them. Imagine building a beautiful storefront, then locking the door for anyone who cannot climb three steps to reach it. That is precisely what an inaccessible website does to millions of users with visual, motor, auditory, or cognitive differences. For a business trying to grow in India's competitive digital market, this is not just an ethical gap - it is lost revenue, lost trust, and in some sectors, genuine legal exposure.

A Strategic Cpluz Perspective

Most agencies treat accessibility as a compliance exercise: run an automated scanner, patch the flagged issues, move on. We approach it differently at Cpluz through what we call the "P-E-R" framework: Perceivable, Explorable, Recoverable. Perceivable asks whether every user, regardless of sense impairment, can register that content exists. Explorable asks whether they can move through your site using their preferred input method, whether that is a keyboard, a switch device, or voice command. Recoverable asks whether users can undo mistakes without a support call. This is a counter-intuitive shift because most teams stop at Perceivable - fixing alt text and color contrast - and never test whether a user can actually complete a purchase or fill a form without a mouse. In our work with fintech clients at Cpluz, we've found that Explorable and Recoverable failures cause far more abandoned sessions than missing alt text ever does, simply because they block the entire task, not just one element on the page.

Why Does Missing Alt Text Still Break Accessibility?

Missing or meaningless alt text remains one of the most common web accessibility errors because screen reader users depend on it to understand images that carry information. A product photo with no description, or worse, an alt attribute reading "image1234.jpg," leaves a shopper with no idea what they're about to buy. This extends beyond photos to icons used as buttons - a shopping cart icon with no accessible label is functionally invisible to assistive technology. A mistake we often see businesses in the tech sector make is treating alt text as an SEO afterthought rather than a genuine description of function or content, which means it satisfies a crawler but fails the actual human being trying to use the page.

How Do Color Contrast and Reliance on Color Alone Exclude Users?

Low color contrast and color-only signaling exclude users with low vision or color blindness by making critical information invisible or indistinguishable to them. Think of a form that marks a required field only with a red asterisk, or an error message that turns a field's border red without any accompanying text. For someone with red-green color blindness, that signal simply does not register. It's well documented that insufficient contrast between text and background forces users to strain or abandon a page entirely rather than persist. The fix is straightforward in principle: pair every color cue with text, an icon, or a pattern, and verify contrast ratios meet recognized thresholds before a design is approved, not after a user complains.

What Happens When a Site Cannot Be Navigated by Keyboard?

Keyboard navigation failures happen when interactive elements - menus, modals, sliders, custom dropdowns - cannot be reached or operated without a mouse, trapping users who rely on keyboards or switch devices. When we redesigned the navigation approach for one of our retail clients, we discovered that their elegant mega-menu looked stunning visually but was entirely unreachable by keyboard; a user could tab into it but never tab back out, effectively trapping them on one section of the site. This is a common lesson in accessibility work: a component can pass every visual design review and still fail the moment a real user tries to operate it without a mouse. The takeaway is that accessibility testing must include an actual keyboard-only walkthrough of every core user journey, not just a visual inspection.

Common Accessibility Errors and Their Impact

Missing or vague alt text - blocks screen reader users from understanding images and icons
Poor color contrast - excludes users with low vision from reading text or identifying states
Broken keyboard navigation - traps users who cannot operate a mouse or touchscreen
Unlabeled form fields - leaves users unsure what information is required or where an error occurred

Why Do Unlabeled Forms Cause the Most Abandonment?

Unlabeled or ambiguously labeled form fields cause abandonment because users cannot determine what information is expected, and error messages that don't explain what went wrong leave them stuck with no path forward. Have you ever submitted a form only to see a vague "Error" message with no indication of which field caused it? That frustration is amplified many times over for someone using a screen reader, who cannot visually scan the page for a red outline. Our team's analysis of client campaigns has repeatedly shown that forms built with proper label associations, clear instructions, and specific inline error text convert measurably better across every type of user, not only those relying on assistive technology.

Addressing these four errors is rarely about a total redesign. It is about embedding accessibility principles into your existing development and design workflow so they are caught before launch, not after a user complains. A tailored accessibility audit, followed by a prioritized remediation plan, tends to deliver far more sustainable results than a one-time automated scan.

Frequently Asked Questions

Q: Is web accessibility only a legal requirement?
A: No, while legal considerations exist in many jurisdictions, accessibility is fundamentally a business strategy that expands your audience, improves usability for all visitors, and strengthens your brand's reputation for inclusivity.

Q: Can automated tools catch every accessibility error?
A: No, automated scanners identify a portion of issues like missing alt text or contrast ratios, but errors involving navigation flow, logical reading order, and genuine usability require manual testing by a human, ideally including someone who uses assistive technology.

Q: Does improving accessibility slow down a website?
A: Not when it's planned correctly. Accessible code tends to be cleaner and more semantic, which often improves load performance and search visibility rather than hindering it.

Q: How often should a business audit its site for accessibility?
A: At minimum, before any major redesign or feature launch, and ideally on a recurring schedule, since new content and features can introduce fresh barriers even on a previously accessible site.
