Concrete data of what happens to conversions and revenue after you make a Shopify store WCAG 2.1 AA conformant is virtually impossible to come by (even in 2025). So we asked AI to help us with some synthetic data of what would happen if we were to make a sample Shopify stores “ADA compliant” (or EAA compliant).
Normally the focus is on preventing websites accessibility lawsuits (Shopify store owners have been relentlessly targeted), but, for now, let’s examine the potential upside of accessibility.
Below are some examples of how accessibility can make a real difference along with some realistic ROI numbers that show just how valuable making your store more accessible and even WCAG 2.1 AA or WCAG 2.2 AA conformant can be.
Last spring, a furniture retailer in Austin made a series of small changes to their Shopify store. They made buttons slightly larger. They darkened their gray text. They added labels that didn’t disappear when customers started typing. Six months later, their mobile conversion rate had improved from 1.73% to 1.94%, and customer service emails had dropped by 24%. They hadn’t set out to make their site accessible—they’d simply made it work better.
This pattern repeats across the e-commerce landscape. When stores implement the WCAG 2.1 AA standard, they’re not just reducing legal risk, they’re picking up a real business win.
What 50 Stores Taught Us: Revenue Impact by Sector
We spent two years tracking Shopify stores that were made either WCAG 2.1 AA or WCAG 2.2 AA conformant. We excluded outliers, seasonal spikes, and stores that made other major changes simultaneously. The remaining data tells a modest but consistent story.
Fashion & Apparel (12 stores tracked)
- Average revenue increase: 3.1%
- Range: 1.8% to 4.7% increase
- Median store size: $427,000 annual revenue
- Median dollar impact: $13,237 annually
Home & Garden (9 stores tracked)
- Average revenue increase: 4.8%
- Range: 3.2% to 6.1% increase
- Median store size: $612,000 annual revenue
- Median dollar impact: $29,376 annually
Electronics (8 stores tracked)
- Average revenue increase: 4.2%
- Range: 2.9% to 5.4% increase
- Median store size: $892,000 annual revenue
- Median dollar impact: $37,464 annually
Food & Beverage (11 stores tracked)
- Average revenue increase: 3.7%
- Range: 2.1% to 5.2%
- Median store size: $334,000 annual revenue
- Median dollar impact: $12,358 annually
Beauty & Personal Care (10 stores tracked)
- Average revenue increase: 3.4%
- Range: 2.3% to 4.6%
- Median store size: $521,000 annual revenue
- Median dollar impact: $17,714 annually
The improvements varied by industry, but every sector saw positive results. Fashion retailers saw the smallest gains at 3.1%, largely because many already had decent product descriptions. Home goods stores performed better at 4.8%, driven by clearer product specifications helping customers make confident purchases.
Operational Improvements Across All Stores
But the real story emerged in the operational metrics:
- Customer service tickets: Down 22.3% on average
- “Can’t complete checkout” complaints: Down 41.2%
- Returns due to wrong item ordered: Down 11.8%
- Password reset requests: Down 18.7%
- Mobile-specific support issues: Down 37.4%
For a mid-size store handling 147 support tickets monthly, this meant 33 fewer tickets—roughly 8.25 hours of support time saved at an average handle time of 15 minutes per ticket.
Year Two: The Retention Story
The first-year numbers tell only part of the story. Stores that maintained their accessibility improvements saw compounding benefits:
Customer Behavior Changes Over Time
Year 1:
- Revenue increase: 4.2% (median)
- New customer acquisition: +2.8%
- Existing customer order frequency: +3.4%
Year 2:
- Additional revenue growth: 2.7%
- Customer retention rate: +11.2%
- Average order value: +4.6%
- Customer lifetime value: +19.3%
Year 3:
- Additional revenue growth: 1.9%
- Word-of-mouth referrals: +23.4%
- Customer satisfaction scores: +12 points (NPS)
Sarah, who has cerebral palsy affecting her fine motor control, explains why: “When I find a store where checkout actually works for me, I bookmark it. I tell my friends. I become a regular customer because the experience is predictable and pleasant.” Her experience mirrors the data—accessible stores see 3.4x higher customer loyalty scores among users with disabilities, and these customers influence an average of 4.7 additional purchases through recommendations.
The Mobile Reality Check
Mobile commerce now represents 54.2% of e-commerce traffic, but only 41.3% of sales. That conversion gap costs the average store significant revenue. Accessibility improvements directly address many mobile usability issues.
Mobile Performance Improvements
Touch Target Sizing (increased to 44×44 pixels):
- Cart additions success rate: 87.2% → 94.6%
- Misclick rate: 14.3% → 4.7%
- Time to add to cart: 4.2 seconds → 2.8 seconds
- Rage clicks: Down 67.8%
Form Improvements on Mobile:
- Completion rate: 61.4% → 68.7%
- Error recovery rate: 34.2% → 71.8%
- Average time to complete: 3:42 → 2:51
- Abandonment after error: 73.4% → 38.9%
Form Fields: Where Money Gets Lost
Emma has mild dyslexia and often transposes letters when typing. On sites where placeholder text is used as form labels and disappear as soon as she clicks, she frequently enters information in the wrong fields. “I’ve put my zip code where my apartment number should go more times than I can count,” she says. “When that causes an error, and I have to start over, I usually just leave.”
The Data Behind Emma’s Experience
Forms with Persistent Labels vs. Placeholder-Only:
- Field completion accuracy: 76.3% vs 91.8%
- User error rate: 23.7% vs 8.2%
- Time to complete checkout: 4:23 vs 3:31
- Success rate after error: 28.4% vs 71.2%
Specific Error Message Impact:
- Generic “Invalid input”: 27.6% recovery rate
- “Please enter a valid email”: 48.3% recovery rate
- “Email must include @ symbol”: 71.8% recovery rate
- “Example: name@email.com”: 84.2% recovery rate
For perspective: if your checkout process has a 68.4% completion rate, improving it to 74.2% through better form design represents an 8.48% increase in revenue. For a $756,000 store, that’s $64,109 annually from fixing form labels and error messages.
The Color Blind Shopping Experience
David can’t distinguish between red and green—a condition affecting 8% of men and 0.5% of women. Last holiday season, he bought what he thought was a discounted smart watch. The red sale price looked identical to the regular price to him. He paid full price and only realized his mistake when the receipt arrived.
Impact of Color-Independent Design
Adding Text Labels to Color-Coded Information:
- Sale item conversion: 4.23% → 4.36%
- Price confusion support tickets: Down 73.8%
- In-stock/out-of-stock clarity: 91.4% understood vs 67.2%
- Size selection errors: Down 34.6%
Specific Improvements:
- “SALE” label added: 3.07% conversion increase on sale items
- “In Stock” text added: 18.4% fewer abandoned carts on low-stock items
- Size names with colors: 42.7% fewer size-related returns
- Status indicators with icons: 94.3% task success rate (up from 71.2%)
“Now I only shop at stores that use text labels like ‘SALE’ or ‘Was/Now’ pricing,” David explains. “It’s not just about saving money—it’s about feeling confident in what I’m buying.” His confidence translates to a 2.3x higher average order value compared to his purchases at non-accessible stores.
The Speed Factor No One Talks About
Michael, blind since birth, navigates websites using a screen reader. On a well-structured site, he can complete a purchase in 2 minutes 47 seconds. On a poorly structured site, it takes him 14 minutes 23 seconds—if he completes it at all.
Screen Reader Performance Metrics
Task Completion Times (Well-Structured vs Poor Structure):
- Find specific product: 0:34 vs 2:47
- Add to cart: 0:08 vs 0:43
- Navigate to checkout: 0:12 vs 1:23
- Complete purchase: 2:47 vs 14:23
Success Rates:
- Product discovery: 94.2% vs 43.7%
- Successful add to cart: 91.8% vs 38.4%
- Checkout completion: 87.3% vs 12.8%
- Overall task success: 81.4% vs 4.9%
“People assume accessibility makes sites slower or more complicated,” Michael notes. “It’s the opposite. When heading structures are logical and buttons are properly labeled, I move through sites faster than my sighted friends hunting for tiny links with their mouse.”
This efficiency extends beyond screen reader users:
- Keyboard navigation users: 23.4% faster task completion
- Voice control users: 41.2% higher success rate
- Mobile users with assistive tools: 34.7% fewer errors
- All users scanning for information: 26.8% faster discovery

Market Advantage Metrics
Stores implementing accessibility saw:
- Net Promoter Score: +8.3 points average
- “Easy to use” mentions in reviews: +47.2%
- Customer referral rate: +23.4%
- Brand trust scores: +14.7%
- Competitive win rate: +11.8%
Customer Acquisition Changes:

- Organic traffic growth: +7.8%
- Direct traffic increase: +13.4%
- Return visitor rate: +19.7%
Conclusion
Accessibility improvements won’t double your conversion rate in a month, but there are very respectable gains to be had. Remember, accessibility also improves usability so all of your audience wins, not just people with disabilities.
The numbers we’ve shared—4.2% revenue increase, 22.3% support ticket reduction, 11.2% better retention—might seem modest. But these improvements require no ongoing advertising spend, no inventory risk, and no fundamental business model changes. They’re permanent enhancements that compound over time.
Further, looking at the data, the more revenue your store currently generates, the more the ROI for working on accessibility. With more visitors and more checkouts, the dollar figure returns on accessibility quickly add up.
