Creating ADA-compliant display ads is not just about ticking a legal checkbox—it’s about ensuring digital inclusion for all. At SizeIM, we believe accessibility should be integral to the creative process, not an afterthought. When your ads are responsive and accessible, you reach a broader audience and reinforce your brand’s reputation for care and innovation. Here’s how we (and you) can approach ADA-compliant display ad design, ensuring every campaign is both beautiful and accessible across every platform and resolution.
Why ADA Compliance Matters in Display Ads
- Legal requirement: Ads must meet web accessibility standards per the Americans with Disabilities Act (ADA) and, globally, WCAG guidelines.
- Wider reach: Accessible ads ensure that users with visual, auditory, motor, or cognitive disabilities engage with your message.
- Better user experience: Accessibility improves ad performance and user trust, which benefits your campaign ROI.
Step 1: Prioritize Accessible Visual Design
We always start by considering the visual elements that directly impact accessibility:
- Contrast: Keep a minimum contrast ratio of 4.5:1 between foreground (text/icon/button) and the background. This ensures readability for users with low vision or color blindness.
- Color as information: Never use color alone to convey meaning. Pair color cues with icons, patterns, or text cues to make information clear for everyone.
- Flashing content: Avoid rapid animations or flashing effects beyond three flashes per second to prevent seizure risks for photosensitive users.
Step 2: Structure Ad Content for Screen Readers
Assistive technologies rely on semantic and descriptive content rather than visuals. Here’s what we focus on:
- Alt text for all images and graphics: Every key visual must have relevant alt text (e.g., alt=”Ad: Up to 40% off on travel bags”). This enables screen readers to describe the ad’s purpose and offer.
- Button and link labels: Interactive elements (CTAs, links) need descriptive text or
aria-labelattributes (e.g.,aria-label="Shop Travel Deals"), so users understand what action each element triggers. - Keyboard navigation: All elements must be accessible by Tab and Enter keys, supporting users who can’t use a mouse.
Step 3: Design Accessible Multimedia Elements
Multimedia is increasingly common in display advertising. To be ADA-compliant:
| Ad Element | Accessibility Requirement |
|---|---|
| Video | Provide closed captions and audio descriptions for spoken/action content. |
| Audio | Include a full transcript available for users with hearing impairments. |
| Animated banners | Give users pause or stop controls, and keep motion simple and cycles short (under 5 seconds). |
When in doubt, simpler is often better—avoid autoplay with sound, unnecessary loops, and dense visual noise.
Step 4: Technical Compliance Best Practices
The back-end code behind your ad matters just as much as what users see:
- Semantic HTML: Use proper
<button>and<a>tags for actions, rather than generic<div>or<span>tags. - ARIA attributes: Where semantics aren’t enough, ARIA labels provide accessible text for assistive technology (e.g.,
aria-label="Dismiss ad"for a close button). - Visible focus indicators: Elements should display a visible outline or style when navigated with a keyboard, helping users track their position.
- Consistent heading structure: If your ad mimics a mini-web page, use
<h1>,<h2>, etc., appropriately for logical document hierarchy. This way, screen readers can parse and navigate your ad structure.
Step 5: Validate and Test Your Ads
Before publishing, every ad should go through:
- Automated accessibility scans: Tools like axe or Lighthouse can flag contrast issues, missing alt attributes, and keyboard traps. While these aren’t perfect, they catch many easy-to-fix barriers.
- Manual testing: Use screen readers (like JAWS or NVDA) and navigate solely by keyboard to experience your ad as a user with disabilities would.
- User feedback: Where possible, ask users with disabilities to review your ad and share their experiences. Nothing beats real-world input.
Common Pitfalls—What to Avoid
- Auto-playing media with audio: This can be a barrier for users with hearing impairments or who use assistive tech.
- Tiny, low-contrast text in animated elements: These are both hard to read and easily missed by screen readers.
- Missing labels for input fields in lead generation ads: Every form element—email, name fields, checkboxes—needs clear labels, not just placeholder text.
