How to Create an Autism-Friendly Website: 5 Mistakes to Avoid and How to Test

Neon accents, large saturated backgrounds, and several bright colors competing on one screen can be overstimulating. Lowering contrast won't fix it, since text still needs to meet WCAG contrast (4.5:1 for normal text). What helps is fewer, calmer colors: a muted base, one accent reserved for the action you want, and dark text on a light, plain background.

If your brand palette is loud, keep the brand colors for small, deliberate moments (the logo, the primary button) rather than painting whole sections with them.

A top bar, a sidebar, a mega menu, and a hamburger that each show different options. Where do you even start?

Pick one navigation pattern and keep it in the same place on every page. WCAG calls this consistent navigation, and it's a Level AA requirement. For a manufacturer, organize it around what buyers look for: products or processes, industries served, capabilities and certifications, and a clear way to request a quote. Our article on what manufacturing buyers check on your website walks through that order.

An autoplaying hero video, a carousel that rotates every three seconds, a cursor trail, a bouncing chat button. Each one pulls attention away from the content, and together they make a page hard to read.

• Give people control. WCAG 2.2.2 (Pause, Stop, Hide, Level A) requires a way to pause, stop, or hide anything that moves automatically for more than five seconds alongside other content.
• Respect the setting. Many people turn on "reduce motion" in their operating system. The CSS prefers-reduced-motion media query lets your site honor it.
• Default to still. Put a play button on the trade show reel or the factory tour video instead of autoplaying it. Replace carousels with one strong, static message.

As a bonus, less motion usually means a lighter, faster page.

The W3C's cognitive accessibility guidance includes a pattern called "Use Literal Language," alongside "Explain Implied Content" (W3C COGA). Idioms, sarcasm, and clever wordplay can be hard to decode, and so can marketing claims that never say what they mean.

"We go the extra mile" says nothing, while "We ship most orders within five business days and confirm the date when you order" tells the buyer something they can plan around. Literal copy is easier for autistic readers, for buyers reading in a second language, and for the AI tools that now summarize your site for buyers.

A newsletter modal on arrival, a chat window that opens itself, and a push notification request, all before the visitor has read a sentence. The W3C guidance calls this out directly: "Limit Interruptions" is one of its patterns for helping users focus.

Show one thing at a time. Let the chat button wait to be clicked. Ask for an email address after someone has read something worth subscribing to, not before.

Start with a free scan to catch the machine-detectable issues: missing alt text, unlabeled form fields, low contrast, broken heading structure.

• Tools: WAVE from WebAIM and axe DevTools both run in the browser. Lighthouse, built into Chrome DevTools, includes an accessibility audit.
• How: Scan your key templates as well as the homepage: a product page, a capability page, and the quote or contact form.

Be wary of "overlay" widgets that promise one-line compliance. In January 2025 the FTC announced a $1 million settlement with accessiBe, finalized in April 2025, alleging it overstated what its accessibility plug-in could do, including a claim that it could make websites WCAG compliant within 48 hours (FTC, 2025). A widget also adds exactly the kind of extra interface this article argues against, so fix the code instead.

Automated tools miss a lot. Two manual checks catch most of the rest.

• Keyboard: Put the mouse away and use Tab, Shift+Tab, Enter, and Space to reach every link, button, and form field. You should always see where you are (a visible focus ring), and you should never get stuck. WebAIM's keyboard guide explains what to look for.
• Screen reader: Use VoiceOver on Mac or NVDA on Windows, both free, and listen to the page top to bottom. Headings should read in a logical order (H1, then H2, then H3), and buttons should say what they do.

Recruit a few people with different disabilities, including autistic and other neurodivergent people, and ask them to complete a real task: find a product spec, request a quote. Watch where they hesitate. The W3C has guidance on involving users in evaluating accessibility, including how to do it respectfully.

Alt text tells a screen reader user what an image shows and why it's there. Describe what matters ("CNC-machined aluminum housing, anodized black, shown next to a ruler for scale") instead of the file name. Mark purely decorative images with empty alt text so they're skipped. Good alt text also helps image search.

The Web Content Accessibility Guidelines are the reference standard, and WCAG 2.2 has been the current W3C Recommendation since October 2023. Level AA is the usual target. It's also the level the US Department of Justice requires of state and local government websites, under WCAG 2.1 (ADA.gov), which matters if you sell to them.

Use the WCAG 2.2 Quick Reference to check each fix against a specific success criterion, so you know what you meet and what you don't yet.
