How to Make a Website Accessible: Step-by-Step Guide

Making a Site Accessible: Where to Start?

106 RGAA criteria. That number alone can be paralyzing. I've seen entire teams freeze up when they first open the audit checklist. Don't worry -- it's easier than it sounds when you break it down. Here's the trick I use: tackle it in layers, starting with the quick wins.

Step 1: Initial Audit

Before you fix anything, you need to know where you stand. Run an automated scan with RGAA Test (rgaa-test.fr) -- it takes a few minutes and gives you a clear snapshot. Automated tools catch about 30-40% of issues, which is a solid starting point. Then roll up your sleeves for manual checks: unplug your mouse and try keyboard navigation, fire up NVDA or VoiceOver, zoom to 200%, disable CSS. You'll be surprised what you find.

Step 2: Fix the Basics (Level A)

Start with the low-hanging fruit. Add descriptive alt text to informative images, empty alt="" on decorative ones. Check your contrast ratios (4.5:1 minimum for normal text -- that light gray on white probably doesn't pass). Set up proper heading hierarchy, add HTML5 landmarks, make sure every form field has a visible label. Here's a trick I use: the placeholder is NOT a label. I've taught this to hundreds of devs and the lightbulb moment is always the same.

Step 3: Deepen (Level AA)

Basics done? Nice. Now go deeper: synchronized video subtitles (no, YouTube auto-captions don't count), 200% zoom support without breaking layout, visible focus indicators on every interactive element, and descriptive link text. "Click here" tells nobody anything.

Step 4: Test and Validate

Re-run your RGAA Test audit and compare with your initial results -- you should see real improvement. Test critical user journeys with a screen reader. If you can involve users with disabilities, their feedback is invaluable.

Step 5: Publish and Maintain

Publish your accessibility statement (it's a legal requirement), set up a feedback mechanism, and train your content contributors. Accessibility isn't a checkbox you tick once -- it's an ongoing commitment.

Accessibility is a marathon, not a sprint. Every new piece of content needs to meet RGAA standards. But you're already on the right track by reading this.
It really depends on the project size. For a 10-20 page site, expect 2-4 weeks of focused work. For something complex like an e-commerce platform, you're looking at 3-6 months. But here's the good news: your initial audit with RGAA Test takes just a few minutes, and it gives you a clear picture of where to start.
No, and that's the good news! In most cases, you can fix things on the existing site. The most common errors -- missing alt text, poor contrast, absent labels -- can all be fixed without a redesign. I've rarely seen a site that actually needed a full rebuild for accessibility.
The legal target is 100% on applicable criteria. Realistically, aim for 75% first -- that already covers the major issues and shows real commitment. Then work your way up. The multi-year accessibility plan lets you spread this over 3 years, so don't feel pressured to fix everything overnight.
