How to Prioritize Accessibility Issues on Your Website

Website accessibility is about inclusion, usability, and reaching your entire audience, not just compliance. But identifying accessibility errors can feel overwhelming. The 2026 WebAIM Million report, which scans the top one million home pages, found an average of 56 detectable errors per page, and nearly 96% of those pages had at least one WCAG failure. Knowing how to prioritize is what turns a daunting list into a workable plan. A strategic approach lets you tackle the most impactful barriers first and improve the experience for real users efficiently.

Why Timing Matters Right Now

For state and local government entities, prioritization isn’t just good practice anymore. It’s tied to a deadline. Under the Department of Justice’s ADA Title II rule, government entities serving populations of 50,000 or more must meet WCAG 2.1 AA by April 26, 2027. Entities under 50,000 and special district governments have until April 26, 2028. If your organization is government-adjacent, or you serve clients who are, that timeline reshapes what “high priority” means. The work needs a plan, not a scramble.

Even if your organization sits outside Title II, the same prioritization logic applies. The legal landscape keeps moving, and a site built with accessibility in mind protects you on multiple fronts at once.

A Step-by-Step Guide to Prioritization

1. Begin with a basic assessment. Conduct an initial audit using resources like the W3C WAI Preliminary Evaluation Guide. Focus on manual checks for fundamental barriers: keyboard navigation, image text alternatives, page structure, and color contrast. This surfaces the easily fixable, high-impact issues first.

2. Add automated tools. Use automated testing tools such as WAVE, axe, and Lighthouse to detect common issues like missing alt text, incorrect heading structure, ARIA misuse, and insufficient contrast. Keep in mind that automated tools catch only a fraction of potential problems, so manual testing and user feedback remain essential. The W3C WAI Tools List offers a full selection.

This is also where continuous monitoring earns its place. One-off scans catch issues the day you run them, but content changes constantly. A monitoring platform like Insi, our in-house accessibility tool, scans pages on an ongoing basis and flags new issues as they appear, so accessibility doesn’t quietly drift after launch. Reach out if you’d like to see how it fits into a team’s workflow.

3. Categorize and prioritize what you find. Don’t try to fix everything at once. Classify issues by severity and real user impact:

• High priority (blocks access): These prevent people from using key content or functionality and map to WCAG Level A failures. Examples include interactive elements (buttons, forms, links) that can’t be operated by keyboard, missing or incorrect form labels, content invisible to screen readers, and keyboard traps. A keyboard trap, for instance, can lock out screen reader and motor-impaired users entirely. Address these immediately, especially on high-traffic pages.
• Medium priority (degrades experience): These make the site harder to use but don’t block access, and they often map to Level AA. Examples include poor color contrast, improper heading levels, and confusing link text. Schedule these for upcoming updates.
• Low priority (minor or cosmetic): Enhancements like decorative images with unnecessary alt attributes, redundant ARIA roles, or minor semantic markup issues. Handle these during ongoing maintenance.

4. Consider scope and frequency. Evaluate how widespread an issue is. Does it affect core pages or multiple components? Does it behave differently on mobile and desktop? Fixing reusable elements like headers and navigation yields the biggest improvement for the least effort, since one fix corrects the issue everywhere that element appears.

5. Triage when resources are tight. Most organizations can’t fix everything at once, and that’s the real question prioritization answers. Two filters help when you have to choose: traffic and exposure. Start with your most-visited pages, since fixing a barrier there helps the most people fastest. Then weigh legal and reputational risk, especially for anything tied to a compliance deadline or a core service people rely on. A barrier on your homepage or application form outranks one buried three clicks deep.

6. Build accessibility into your ongoing workflow. Accessibility isn’t a one-time task. Add accessibility checks to QA and code reviews, train your team regularly, run automated scans with each deployment, and seek feedback from users with disabilities. The goal is to prevent new issues rather than chase old ones.

The Bottom Line

Prioritizing accessibility comes down to a repeatable process: evaluate, test with both tools and people, categorize by severity and real impact, weigh scope and exposure, and build the habit into your development cycle. Done consistently, it turns accessibility from a compliance headache into a steady advantage.

If you’re staring at an audit report and not sure where to start, or you’re facing one of the ADA Title II deadlines and need a clear plan, that’s exactly the kind of work our Blueprint process is built for. We can help you map your issues to a phased remediation plan that fits your timeline and budget. Reach out and we’ll take a look together.
