Web Accessibility Checklist: 7 Standards Every Site Must Meet [Guide]

A robust web accessibility checklist is no longer a nice-to-have; it is a foundational requirement for any business serious about reaching every possible customer. Think of your website as a physical storefront. If half your entrances have staircases but no ramps, you are turning away customers before they even see what you sell. Digital accessibility works the same way, and yet it remains one of the most overlooked aspects of website design in India today. This guide walks you through the seven standards your site must meet, along with the reasoning behind each one, so you can build a digital presence that genuinely welcomes everyone.

A Strategic Cpluz Perspective

Most accessibility guides treat compliance as a checkbox exercise: run an automated scanner, fix the flagged errors, move on. We think that approach misses the point entirely. In our work with clients across sectors, we have developed what we call the A-P-E Model for Accessibility: Automated, Perceptual, Experiential.

Automated testing catches roughly a third of real issues - missing alt text, contrast ratios, missing labels. Perceptual testing means actually using your site with a screen reader or keyboard-only navigation to understand how it feels. Experiential testing goes further still: it means recruiting a small panel of users with different abilities to complete real tasks on your site, such as booking a consultation or submitting an inquiry form.

A mistake we often see businesses in the tech sector make is stopping at the automated stage and declaring victory. Automated scanners cannot tell you whether your focus order makes logical sense, or whether your error messages actually help someone recover from a mistake. True accessibility is achieved when a person using assistive technology can complete the same task, in a comparable amount of time, as a sighted mouse user. That is the standard worth aiming for.

What Is the Foundation of Any Web Accessibility Checklist?

The foundation is the Web Content Accessibility Guidelines, commonly known as WCAG, built around four principles: content must be Perceivable, Operable, Understandable, and Robust. Every item on a proper web accessibility checklist traces back to one of these four pillars. When we redesigned the approach for one of our e-commerce clients, we discovered that framing every design decision through this lens - rather than treating accessibility as a separate audit - dramatically reduced the number of retrofits needed later in development.

The 7 Standards Your Site Must Meet

Sufficient color contrast - Text must stand out clearly against its background so users with low vision or color blindness can read it without strain.
Keyboard navigability - Every interactive element, from menus to forms, must be fully operable using only a keyboard, with a visible focus indicator at each step.
Descriptive alt text - Images must carry meaningful alternative text so screen reader users understand what they cannot see.
Logical heading structure - Headings should follow a clear hierarchy, allowing screen reader users to navigate content the way a sighted user would scan a page.
Accessible forms - Labels, error messages, and instructions must be programmatically associated with their fields, not just visually placed nearby.
Captions and transcripts - Video and audio content needs text alternatives for users who are deaf, hard of hearing, or simply browsing without sound.
Responsive, resizable text - Users must be able to enlarge text up to 200 percent without breaking the layout or losing content.

Consider a startup we advised that had built an otherwise polished product page. Every image lacked alt text, and their "Buy Now" button existed only as a styled <div> rather than a real button element - meaning keyboard and screen reader users could never activate it. Once we corrected the semantic markup and added descriptive alt attributes, their support tickets referencing "cannot complete purchase" dropped noticeably within the following month. The lesson here is straightforward: accessibility gaps often hide inside details that look fine visually but break down entirely for assistive technology.

How Do You Test Your Site Against This Checklist?

You test it by combining automated tools with genuine human review, never relying on either alone. Start with an automated scanner to catch obvious technical errors quickly. Then navigate your entire site using only your keyboard's Tab key - can you reach every link, button, and form field in a sensible order? Next, enable a screen reader and listen to how your content is announced. Does it make sense out of context? Finally, wherever budget allows, invite actual users with disabilities to test key workflows.

What Are Common Mistakes Businesses Make With Accessibility?

The most common mistake is treating accessibility as a one-time project rather than an ongoing discipline woven into every design and development sprint.

Bolting it on at the end - Accessibility retrofitted after launch is always more expensive and less effective than accessibility built in from the first wireframe.
Ignoring dynamic content - Pop-ups, sliders, and interactive widgets are frequently forgotten, even when the rest of the site is compliant.
Assuming compliance equals usability - Passing an automated audit is not the same as delivering a genuinely comfortable experience.

Frequently Asked Questions

Q: Is following a web accessibility checklist legally required in India?
A: While India's specific accessibility legislation continues to evolve, businesses serving global markets or government contracts increasingly face binding accessibility requirements, making early compliance a strategic advantage rather than a burden.

Q: How much does it cost to make a website accessible?
A: Cost varies by site complexity, but building accessibility in from the start is consistently more economical than retrofitting an existing site after launch.

Q: Does accessibility work conflict with good visual design?
A: No, thoughtful accessibility and strong visual design are complementary; constraints like sufficient contrast and clear hierarchy tend to produce cleaner, more intuitive interfaces overall.

Q: How often should we re-audit our site for accessibility?
A: Treat it as an ongoing practice, with a full review after any major redesign and lighter checks after each significant content or feature update.
