Website Accessibility Checker: How to Test Your Site in 5 Minutes

You’ve built a beautiful website. It looks great, functions smoothly, and you’re proud of it. But here’s a question that might keep you up at night: can everyone actually use it?

Website accessibility isn’t just a nice-to-have feature anymore. With legal requirements tightening globally and search engines favoring accessible sites, testing your website’s accessibility has become essential. The good news? You don’t need to be a technical expert or spend hours manually checking every page. You can get a comprehensive overview of your site’s accessibility in just five minutes.

Let’s walk through exactly how to do it.

Why Testing Website Accessibility Matters

Before diving into the how, let’s talk about the why. Testing your website for accessibility issues serves multiple critical purposes that directly impact your bottom line.

First, there’s the legal landscape. The European Accessibility Act goes into effect in 2025, requiring many websites to meet specific accessibility standards. In the United States, ADA lawsuits related to website accessibility continue to rise year after year. Waiting until you receive a legal notice is risky and expensive.

Second, accessibility directly affects your SEO performance. Search engines like Google have explicitly stated that accessibility is a ranking factor. Sites that are easier to navigate with assistive technologies are also easier for search engine crawlers to understand and index. This means accessible websites often rank higher than their inaccessible competitors.

Third, you’re potentially losing customers. Around 16% of the global population experiences some form of disability. When your website has accessibility barriers, you’re excluding a significant portion of your potential audience. Every person who can’t navigate your checkout process or read your content is a lost opportunity.

Finally, accessibility improvements benefit everyone, not just people with disabilities. Clear navigation, readable text, and logical page structure make your site easier to use for all visitors, regardless of their abilities.

What to Look for When Testing Accessibility

When you test your website for accessibility, you’re checking whether people using assistive technologies like screen readers, keyboard navigation, or alternative input devices can successfully use your site. You’re also verifying that your content is perceivable, operable, understandable, and robust (the four principles of WCAG compliance).

Here are the key areas every accessibility test should cover:

Color Contrast: Text must have sufficient contrast against its background. Low contrast makes content difficult or impossible to read for people with visual impairments or color blindness.

Keyboard Navigation: Every interactive element on your site should be accessible using only a keyboard. Many people cannot use a mouse due to motor disabilities.

Alternative Text: Images need descriptive alt text so screen reader users understand the content and context of visual elements.

Form Labels: Every form field requires a proper label that’s programmatically associated with the input. Without this, screen reader users won’t know what information to enter.

Heading Structure: Headings should follow a logical hierarchy (H1, H2, H3) to help users navigate your content efficiently.

Link Purpose: Links should have descriptive text that makes sense out of context. “Click here” doesn’t tell users where they’re going.

ARIA Usage: ARIA (Accessible Rich Internet Applications) attributes help make dynamic content and complex interfaces accessible, but they must be implemented correctly.

How to Test Your Website Accessibility in 5 Minutes

Now for the practical part. Here’s how to get a comprehensive accessibility audit in just five minutes.

Step 1: Run an Automated Scan (1 minute)

The fastest way to identify accessibility issues is using an automated website accessibility checker. Scanluma scans your website, checking against WCAG guidelines and flagging issues that need attention.

To get started:

1. Enter your website URL
2. Click scan
3. Wait for the complete site analysis

Within a minute, you’ll receive a detailed report showing exactly which accessibility issues exist, where they’re located, and what priority level they represent. The scanner checks for dozens of common problems, from missing alt text to insufficient color contrast, giving you a bird’s-eye view of your accessibility status.

Automated scanning catches roughly 30-40% of accessibility issues, which is a significant starting point. These are typically the technical violations that are easiest to fix and have the biggest impact when resolved.

Step 2: Review Critical Issues First (1 minute)

Your scan results will categorize issues by severity. Focus on critical and serious issues first since these are the problems most likely to block users from accessing your content.

Look for patterns in the results. If you see the same issue repeated across multiple pages, that suggests a template-level problem that can be fixed once and applied site-wide. This is especially common with issues like missing form labels or improperly nested headings.

Pay special attention to issues on high-traffic pages like your homepage, key landing pages, and checkout process if you run an e-commerce site. These pages have the biggest impact on user experience and business outcomes.

Step 3: Check a Sample Page Manually (1 minute)

While automated testing is powerful, some accessibility issues require human judgment. Spend a minute on manual testing to catch things that scanners miss.

Try navigating a key page using only your keyboard. Press the Tab key to move through interactive elements. Can you reach everything? Is the focus indicator visible? Does the tab order make logical sense?

Turn on a screen reader (most operating systems have one built in) and listen to how it reads a paragraph of your content. Does it make sense? Can you understand the structure and meaning?

These quick manual checks help you understand the real user experience and catch context-dependent issues that automated tools can’t always identify.

Step 4: Examine Your Most Common Issue (30 seconds)

Look at which accessibility issue appears most frequently in your scan results. This is often something like missing alt text on images or low color contrast.

Understanding your most common issue helps you prioritize remediation efforts. If 200 images are missing alt text, you know that’s where you’ll get the most impact from your fixing efforts.

H3: Step 5: Create Your Action Plan (30 seconds)

Based on what you’ve learned, quickly outline your next steps:

• What’s the #1 priority issue to fix?
• Which pages need immediate attention?
• Do you need to update your website template or theme?
• Should you schedule regular accessibility scans?

Having a clear action plan transforms your test results from information into improvement.

Common Accessibility Issues to Watch For

As you test your website, certain accessibility problems tend to appear more frequently than others. Being aware of these common issues helps you spot them quickly and understand their impact.

Missing Alternative Text on Images: This is one of the most prevalent accessibility violations. Every image that conveys meaning needs descriptive alt text. Decorative images should have empty alt attributes (alt=””) so screen readers skip them.

Insufficient Color Contrast: Text and background colors must meet minimum contrast ratios, typically 4.5:1 for normal text and 3:1 for large text. Many modern, minimalist designs accidentally create contrast issues with their light gray text on white backgrounds.

Empty Links and Buttons: Links that contain only an icon or image without text are impossible for screen reader users to understand. Every link needs descriptive text, even if that text is visually hidden.

Missing Form Labels: Forms are a major accessibility challenge. Every input field needs a label element properly associated with it using the “for” and “id” attributes. Placeholder text alone is not sufficient.

Poor Heading Structure: Pages that skip heading levels (jumping from H1 to H3, for example) or use multiple H1 tags create navigation confusion for assistive technology users. Think of headings as the table of contents for your page.

Videos Without Captions: Video content must include captions for deaf and hard-of-hearing users. This is both an accessibility requirement and improves user experience for people watching in sound-sensitive environments.

Non-Responsive Design: Sites that don’t work well on mobile devices or when zoomed to 200% create barriers for people with visual impairments who need to enlarge content.

Many of these issues are covered in detail in the guide on common accessibility issues that hurt your website’s SEO, which explains both how to identify and fix each problem.

What to Do After Testing

Testing is just the beginning. The real value comes from taking action on what you discover.

Prioritize by Impact: Start with issues that affect the most users or appear on your most important pages. For e-commerce sites, this means focusing on product pages, cart, and checkout first. If you run an online store, consider reviewing e-commerce accessibility solutions designed specifically for shops.

Fix Systemic Issues: If your test reveals template-level problems, fixing them once updates your entire site. This is far more efficient than page-by-page remediation.

Schedule Regular Testing: Accessibility isn’t a one-time project. New content, design updates, and third-party integrations can all introduce new issues. Schedule automated scans weekly or monthly to catch problems early.

Document Your Progress: Keep records of your accessibility improvements. This documentation serves as evidence of good-faith effort if you ever face legal questions, and it helps you measure progress over time.

Consider Professional Support: If you’re an agency managing multiple client websites, having a systematic approach to accessibility testing becomes essential. Automated scanning tools help you scale your accessibility services across your entire client portfolio while demonstrating ongoing value.

Educate Your Team: Make sure everyone who creates or publishes content understands basic accessibility principles. Content creators who write good alt text and use proper heading structure prevent issues before they happen.

Moving Forward with Confidence

Testing your website accessibility doesn’t need to be complicated or time-consuming. In just five minutes, you can gain valuable insights into how accessible your site really is and identify the specific issues that need attention.

The key is getting started. Many website owners put off accessibility testing because they assume it will be overwhelming or reveal too many problems to fix. In reality, most accessibility issues are straightforward to resolve once you know they exist. Even incremental improvements make your site more usable and reduce legal risk.

Whether you’re a small business owner making sure your site is accessible to all customers, or an agency managing accessibility for multiple clients, regular testing is the foundation of maintaining an inclusive web presence. Automated accessibility checkers like Scanluma remove the technical barriers and give you clear, actionable information about what needs to improve.

Remember, website accessibility is not about achieving perfection overnight. It’s about steady progress toward a more inclusive web that serves all users equally. Start with a five-minute test today, fix your most critical issues, and build accessibility into your regular website maintenance routine.

Your website’s accessibility directly impacts real people trying to access your content, use your services, or purchase your products. Every issue you fix removes a barrier for someone. That’s worth five minutes of your time.
