“The power of the Web is in its universality. Access by everyone regardless of disability is an essential aspect.”

Tim Berners-Lee, Inventor of the World Wide Web

I was trying to buy a gift for a friend. It was 11 PM. I was holding my sleeping nephew in my left arm. I only had my right hand free.

The site looked great. Slick design. Cool animations.

But when I tried to checkout, the “Place Order” button was floating off the screen on my phone. I couldn’t scroll to it. I couldn’t click it.

I tried for 30 seconds. Then I got frustrated. Then I closed the tab and bought it on Amazon.

That store didn’t lose the sale because their product was bad. They lost it because they locked the door.

Most business owners think “Accessibility” is a boring checklist for government compliance. They think it’s charity.

They are wrong. Dead wrong.

Accessibility is the biggest untapped growth hack in e-commerce.

The $13 Trillion Market You Are Ignoring

Let’s do some math.

There are over 1 Billion people in the world with some form of disability. That is 15% of the global population.

Together, they control $13 Trillion in disposable income.

If your website is not accessible, you are essentially hanging a sign on your door that says: “I do not want money from 15% of the population.”

But it gets bigger.

[Inclusive Design]: Designing for the permanent, temporary, and situational limitations of all users.

• Permanent: A user who is blind.
• Temporary: A user with a broken arm.
• Situational: A user holding a baby (like me), or standing in bright sunlight, or on slow airport Wi-Fi.

When you solve for one, you solve for all. When you add captions for the deaf, you help the guy watching videos on the subway with the sound off. When you increase contrast for the elderly, you help the guy looking at his phone on the beach.

Accessibility isn’t about “Helping them.” It’s about helping you make more money.

The Litigation Bomb (The Stick)

If the carrot of $13 Trillion doesn’t move you, maybe the stick will.

In 2023 alone, there were over 4,000 lawsuits filed against websites for ADA violations.

It is not a matter of if a lawyer finds you. It is a matter of when.

• Cost of a lawsuit settlement: $25,000 -$50,000.
• Cost of fixing your code: $5,000.

You do the math. Being inaccessible is a liability. It’s a ticking time bomb in your P&L.

The SEO Bonus (The Hidden Carrot)

Here is a secret that SEO “gurus” charge thousands for:

Google is blind.

Google’s bots scan your code. They don’t “see” your beautiful images. They read your Alt Text. They read your headers. They look for structure.

A screen reader (used by the blind) reads code exactly like Google does.

If you optimize your site for a screen reader, you are optimizing it for Google.

• Clear headings = Better SEO.
• Alt text on images = Better SEO.
• Logical structure = Better SEO.

Accessibility = Rankings = Traffic = Money.

The Accessibility Detection Protocol

Before you fix anything, you need to know where you’re failing. Here’s a 30-minute audit that will reveal your blind spots.

Step 1: The Automated Scan (10 minutes)

Run these free tools on your homepage, top product page, and checkout:

Tool	What It Checks	🚨 Red Flag If
WAVE	Errors, contrast, structure	> 5 errors per page
Axe DevTools	WCAG compliance	> 10 issues per page
Google Lighthouse	Accessibility score	Score < 80

Record your baseline:

• Homepage errors: ___
• Product page errors: ___
• Checkout errors: ___
• Lighthouse accessibility score: ___

🚨 Red Flag: If any page has more than 10 errors, you’re likely losing 5-10% of potential customers.

Step 2: The Manual Navigation Test (10 minutes)

Unplug your mouse. Navigate your site with keyboard only.

Task	Pass/Fail	🚨 Red Flag If
Tab to main navigation		Can’t reach it
Tab to Add to Cart		Can’t find focus indicator
Tab through checkout form		Skips fields or gets stuck
Tab to complete purchase		Can’t submit form
Press Enter on buttons		Nothing happens

🚨 Red Flag: If you can’t complete a purchase with keyboard only, neither can millions of potential customers.

Step 3: The Visual Impairment Simulation (5 minutes)

Test	How to Check	🚨 Red Flag If
Color blindness	Use Coblis simulator	CTA buttons disappear
Low vision	Zoom browser to 200%	Layout breaks
Bright sunlight	Max phone brightness, go outside	Text unreadable
Squint test	Squint at your screen	Buttons invisible

🚨 Red Flag: If your primary CTA becomes invisible under any of these conditions, you’re losing sales every day.

Step 4: The Content Audit (5 minutes)

Content Element	Count	🚨 Red Flag If
Images without alt text	___	> 0 on product pages
Videos without captions	___	Any
Form fields without labels	___	> 0
Links that say “Click here”	___	> 0
PDFs (inaccessible)	___	Any critical info in PDFs

🚨 Red Flag: Missing alt text on product images means screen reader users can’t shop—and Google can’t index.

The 3-Tier Accessibility Fix Framework

Quick Fixes (This Week: 2-8 hours, immediate impact)

1. Fix Color Contrast

Run WebAIM Contrast Checker on your primary colors.

Element	Minimum Ratio	Your Ratio
Body text	4.5:1	___
Large text/headings	3:1	___
Buttons and links	4.5:1	___

Time: 2 hours Impact: Makes text readable for 8%+ of population with vision issues

2. Add Focus Indicators

When users Tab through your site, they should always see where they are.

:focus {
  outline: 3px solid #0066CC;
  outline-offset: 2px;
}

Time: 1 hour Impact: Enables keyboard-only navigation for millions

3. Add Alt Text to Product Images

For each product image:

• Describe what’s shown (not “product photo”)
• Include relevant details (color, material, angle)
• Be concise (under 125 characters)

Time: 2-4 hours (depending on catalog size) Impact: Enables screen reader users to shop + improves SEO

---

Medium Fixes (This Month: 1-3 weeks, systematic improvement)

1. Fix Form Accessibility

• Move labels outside input fields (not placeholders)
• Add error messages that explain what’s wrong
• Associate labels with inputs using for attribute
• Add autocomplete attributes for faster filling

Time: 1 week Impact: 10-20% improvement in form completion for all users

2. Add Skip Links

Let keyboard users skip the navigation and jump to main content.

<a href="#main-content" class="skip-link">Skip to main content</a>

Time: 2-3 hours Impact: Makes navigation dramatically faster for keyboard users

3. Add Video Captions

Every video on your site needs captions:

• Product demos
• Testimonials
• Explainer videos

Time: 1-2 weeks (or use automated services) Impact: Opens video content to 15%+ of users who watch with sound off

---

Deep Fixes (This Quarter: 4-8 weeks, competitive advantage)

1. Full WCAG 2.1 AA Compliance Audit

Hire an accessibility specialist to audit your entire site and create a remediation roadmap.

Time: 4-6 weeks Impact: Legal protection + access to $13T market

Test your site with actual screen readers (VoiceOver, NVDA, JAWS).

Not just automated tools—real user flows:

• Find a product
• Add to cart
• Complete checkout
• Track order

Time: 2-4 weeks Impact: Ensures real-world usability for blind and low-vision users

3. Build Accessibility Into Your Process

• Add accessibility checklist to design review

The “Open Door” Protocol: 5 Simple Fixes

You don’t need to rebuild your site from scratch. You just need to unlock the doors. Here is the 80/20 of Inclusive UX.

1. The “Squint Test” (Contrast)

Go to your website. Squint your eyes until things get blurry. Can you still read the text? Can you see the buttons? If your grey text on a white background disappears, fix it. Low contrast causes eye strain for everyone. Make it black on white. Make it bold. Stop being subtle. Subtle doesn’t sell.

2. The “No Mouse” Challenge

Unplug your mouse. Try to buy a product on your site using only the Tab and Enter keys. If you get stuck, or if you can’t tell where the focus is, you have failed. This is how millions of people navigate the web. If they can’t Tab, they can’t buy.

3. Alt Text Is Not Optional

Every image needs a description. Bad: “img_123.jpg” Good: “Red leather running shoe, side view.” Describe it like you are talking to a friend on the phone. This helps the blind visualize the product, and it helps Google index it.

4. Form Labels

Do not use “placeholders” inside the box as labels. When a user clicks the box to type, the placeholder disappears. Now they forgot what they were supposed to type. Put the label outside the box. “Email Address.” “Phone Number.” Clarity impacts conversion.

5. Use the Tools

You don’t have to guess. Use free tools to check your work.

• WAVE (Web Accessibility Evaluation Tool): It puts red icons on your errors.
• Axe: A chrome extension that audits your page.

Case Study: The Accessibility Revenue Lift

A specialty outdoor gear brand came to me with a mystery. Their traffic was growing, but conversion rate was declining. “Our site looks better than ever,” they said. “We just redesigned it.”

The Situation

Their new design was sleek. Minimal. Trendy. Light gray text on white backgrounds. Subtle animations. Beautiful photography.

And completely inaccessible.

Their numbers told the story:

• Conversion rate: Dropped from 2.8% to 1.9% after redesign
• Bounce rate: Increased 23%
• Mobile conversion: Down 34%
• Checkout abandonment: Up 18%

The Detection Phase

We ran the Accessibility Detection Protocol:

Automated Scan:

• Homepage WAVE errors: 47 (🚨 Critical)
• Product page errors: 31 (🚨 Critical)
• Lighthouse accessibility score: 54 (🚨 Below 80)

Manual Navigation Test:

• Couldn’t Tab to Add to Cart (🚨)
• No visible focus indicator anywhere (🚨)
• Checkout form fields weren’t labeled (🚨)

Visual Impairment Simulation:

• Squint test: Primary CTA invisible (🚨)
• Color contrast on buttons: 2.1:1 (🚨 Should be 4.5:1)
• Text contrast: 2.8:1 (🚨)

Content Audit:

• 340 product images without alt text (🚨)
• Size guide in inaccessible PDF
• All form labels were placeholders

The Real Problem

Their “beautiful” redesign had made the site unusable for:

• 15% of population with disabilities
• Older customers (major demographic for outdoor gear)
• Anyone shopping on a phone in bright sunlight
• Anyone with imperfect vision
• Anyone navigating with keyboard

That’s not a niche. That’s a significant chunk of their customer base.

The Intervention

Week 1-2 (Quick Fixes):

• Fixed color contrast (gray to black text)
• Added focus indicators
• Made buttons visible (higher contrast background)
• Added alt text to top 100 product images

Week 3-4 (Medium Fixes):

• Moved form labels outside input fields
• Added skip links
• Fixed keyboard navigation order
• Converted PDF size guide to accessible HTML

Week 5-8 (Deep Fixes):

• Added alt text to all 2,400 product images
• Conducted screen reader testing
• Built accessibility checklist into design review

The Results

Metric	After Redesign	After Fix	Change
Lighthouse Accessibility	54	94	+74%
Conversion Rate	1.9%	3.2%	+68%
Mobile Conversion	1.1%	2.4%	+118%
Checkout Abandonment	41%	28%	-32%
Organic Search Traffic	Baseline	+23%	SEO boost

Monthly revenue increase: +$87,000 **Annual impact:** +$1.04M

The Unexpected Wins

SEO Boost: Adding alt text to 2,400 images gave them a 23% increase in organic image search traffic within 60 days.

Reduced Support Tickets: Fixing form labels reduced checkout-related support tickets by 45%.

No Lawsuit: Six months earlier, a competitor was sued for accessibility violations. Cost them $40,000 to settle.

The Lesson

Their “beautiful” redesign was costing them over $1 million per year.

Not because the design was wrong. Because they optimized for aesthetics over usability.

The irony? The accessible version looked nearly identical. They just changed colors and added labels.

Accessibility isn’t charity. It’s revenue you’re currently leaving on the table.

The Bottom Line

Making your site accessible is the ultimate selfish act.

You tell yourself you are doing it to be a “good person.” But you are really doing it because:

1. You want the $13 Trillion market.
2. You don’t want to get sued.
3. You want better SEO.

And that is okay.

In the end, everyone wins. Your grandmother can read your font. The blind user can buy your shoes. And you get to keep the profit.

In the next chapter, we’re going to dive into the dark arts of Psychology and Persuasion—how to use the human brain’s bugs to drive even more sales.

Five things to do this week

1. Do The Squint Test: Open your homepage. Squint until it’s blurry. If your “Shop Now” button disappears, change the color immediately. If your text becomes invisible, increase the contrast.
2. Unplug Your Mouse: Try to checkout on your site using only Tab and Enter. If you get stuck, you are blocking 15% of the world. Fix the tab order.
3. Audit Your Alt Text: Go to your top 10 best-selling products. Do the images have names like “DSC_001.jpg”? Change them to descriptive text: “Man exploring a cave wearing the Helios Headlamp.”
4. Fix Your Forms: Go to your checkout. Are the labels inside the boxes? Move them out. Make them visible at all times. This is the easiest conversion lift you will get today.
5. Run a WAVE Audit: Download the WAVE browser extension. Run it on your homepage. It will show you big red errors. Fix the top 3 errors. Ignore the “warnings” for now. Just kill the errors.
