WCAG Compliance by Industry: The Accessibility Gap
Over 1.3 billion people worldwide live with some form of disability. For many of them, the web is not the frictionless experience most designers imagine — it's a daily obstacle course of missing labels, broken navigation, and invisible content. The Web Content Accessibility Guidelines (WCAG) exist to fix this, yet compliance remains remarkably uneven.
We used LLMSE's WCAG accessibility analyzer to evaluate 30 major websites across 10 industries against WCAG 2.1 Level A — the minimum standard. The results reveal a stark accessibility gap: two-thirds of the sites we tested had at least one critical failure, and performance varies wildly by sector.
The Dataset
We selected 30 globally recognized websites spanning ten industries:
| Sector | Sites Analyzed |
|---|---|
| News & Media | NYTimes, BBC, Forbes |
| Technology | GitHub, Stack Overflow, Microsoft |
| E-commerce | Amazon, Walmart, Target |
| Education | Harvard, Coursera, Wikipedia |
| Healthcare | Healthline, WebMD, WHO |
| Government | GOV.UK, IRS, CDC |
| Finance & Banking | Chase, Bank of America, PayPal |
| Travel & Hospitality | Booking.com, Airbnb, TripAdvisor |
| Social & Entertainment | Reddit, IMDb, Spotify |
| Real Estate | Zillow, Realtor.com, Redfin |
Each site was evaluated against 15 automated WCAG 2.1 Level A checks covering alt text, form labels, heading structure, page titles, language attributes, link and button accessibility, ARIA usage, skip navigation, landmarks, viewport zoom, and more. Scores start at 100 and are deducted per severity: -15 for critical issues, -5 for warnings, -1 for informational findings.
The Big Picture: 32,000 URLs Tell the Story
Before diving into our 30-site sample, here's the broader context. LLMSE has analyzed over 32,700 URLs for WCAG compliance. The grade distribution across this entire dataset is sobering:
| Grade | Count | Share |
|---|---|---|
| A (90-100) | 6,070 | 18.5% |
| B (80-89) | 4,006 | 12.2% |
| C (70-79) | 7,194 | 22.0% |
| D (60-69) | 5,706 | 17.4% |
| F (0-59) | 9,777 | 29.9% |
Only 30.8% of websites pass with an A or B grade. Nearly one in three earns an outright F. The web has an accessibility problem, and it is not confined to small or under-resourced sites.
Key Finding: Even Major Sites Fail
Among our 30 high-profile websites, the grade distribution was:
| Grade | Count | Share |
|---|---|---|
| A (90-100) | 9 | 30% |
| B (80-89) | 5 | 17% |
| C (70-79) | 5 | 17% |
| D (60-69) | 4 | 13% |
| F (0-59) | 7 | 23% |
The average score was 73.6 out of 100 — a C grade. While major sites do outperform the general web (30% A grades vs. 18.5% overall), 20 out of 30 sites still had at least one critical accessibility failure. A critical failure means a real barrier exists for users who rely on assistive technology.

Scores by Industry
Industry averages reveal where different sectors stand on accessibility:
| Sector | Avg Score | Avg Grade | Range |
|---|---|---|---|
| Education | 90.0 | A | 80-100 |
| Government | 88.3 | B | 75-95 |
| Travel & Hospitality | 81.7 | B | 75-90 |

| Social & Entertainment | 58.3 | F | 45-75 |
Education Leads, Social Media Trails
Education (90.0 avg) takes the top spot by a wide margin. Harvard earned a perfect 100 — the only site in our sample with zero issues. Academic institutions tend to have accessibility offices, disability resource centers, and a culture of inclusive design that translates directly into their web properties.
Government (88.3 avg) follows closely. GOV.UK and IRS both scored 95. This isn't surprising: government sites in the US, UK, and EU face legal mandates (Section 508, EN 301 549) that require WCAG compliance. Regulation works.
Social & Entertainment (58.3 avg) sits at the bottom. Reddit scored just 45 — missing its language attribute, landmarks, skip navigation, and page title. IMDb had 13 duplicate IDs and multiple empty links. These platforms are built for engagement, not assistive technology, and it shows.
The Top Three Performers
Harvard.edu (100, Grade A) — A clean sweep. Every image has alt text, all headings follow logical hierarchy, skip navigation is present, landmarks are properly used, and the language attribute is set. This is what WCAG compliance looks like when an institution treats it as a priority.
GOV.UK (95, Grade A) — The UK government's design system is widely regarded as a gold standard for accessible public services. Minor heading hierarchy issue is the only deduction. Everything else — labels, landmarks, skip navigation, language — is textbook.
IRS.gov (95, Grade A) — Another government site demonstrating that legal requirements produce results. Comprehensive landmark usage, skip navigation, and properly labeled forms. A single duplicate ID prevents a perfect score.
The Bottom Three Performers
Forbes.com (40, Grade F) — The worst performer in our sample. Five heading-level skips, missing skip navigation, unlabeled form inputs, and poor structural organization. A content-heavy site that has invested in monetization infrastructure but neglected the accessibility basics.
Reddit.com (45, Grade F) — Missing its lang attribute, page title, landmarks, and skip navigation. Reddit's modern SPA architecture delivers minimal HTML to the browser, which creates a cascade of accessibility gaps detectable even in static analysis.
Redfin.com (49, Grade F) — Blocked viewport zoom (preventing users from enlarging text), empty links, duplicate IDs, and missing skip navigation. The zoom-blocking alone is a critical barrier for low-vision users.
Where Websites Fail: The 15 WCAG Checks
Here's how often each issue appeared across our 30-site sample:
| Issue | WCAG Criterion | Severity | Frequency |
|---|---|---|---|
| Heading hierarchy violations | 1.3.1 | Warning | 73% |
| Duplicate element IDs | 4.1.1 | Warning | 53% |
| Missing skip navigation | 2.4.1 | Warning | 50% |
| Empty links (no accessible text) | 2.4.4 | Critical | 27% |
| Missing image alt text | 1.1.1 | Critical | 23% |
| Missing form labels | 1.3.1 | Critical | 20% |
| Missing landmarks | N/A | Warning | 20% |
| Missing page title | 2.4.2 | Critical | 13% |
| Empty buttons | 4.1.2 | Critical | 10% |
| Missing lang attribute | 3.1.1 | Critical | 7% |
| Viewport zoom blocked | 1.4.4 | Critical | 7% |
| Positive tabindex | N/A | Info | 7% |
| Missing ARIA labels | 4.1.2 | Warning | 3% |
Heading Hierarchy: The Most Common Problem
73% of sites had at least one heading-level skip — jumping from H1 to H3, or starting a page with H2 instead of H1. While this is a warning rather than a critical failure, it directly impacts screen reader users who navigate by heading structure. Forbes had five separate heading-level violations. BBC, despite having 143 headings, still managed to skip levels.
This is arguably the easiest issue to fix. Developers simply need to maintain a logical heading order: H1 for the page title, H2 for sections, H3 for subsections, with no levels skipped.
Duplicate IDs: A Hidden Danger
53% of sites had duplicate element IDs. IMDb led with 13 duplicates, followed by GitHub with 11. Duplicate IDs break the relationship between labels and form fields, cause ARIA references to target the wrong element, and violate the HTML specification itself. They're invisible to sighted users but create real confusion for assistive technology.
Missing Skip Navigation: Half the Web
50% of sites lacked skip navigation — a simple "Skip to main content" link that lets keyboard users bypass repetitive navigation menus. This is a well-known WCAG requirement (2.4.1) and one of the simplest to implement: a single anchor link with a couple lines of CSS. Yet half the world's most visited sites don't bother.
Missing Alt Text: Still Happening in 2026
23% of sites had images without alt text. BBC was the worst offender with 59 images missing descriptions out of 118 total — a 50% failure rate. WebMD had 11 missing alt texts on a health information site where visual content often conveys critical medical information.
For screen reader users, an image without alt text is invisible at best and confusing at worst. The screen reader may read the file name instead, producing meaningless output like "stock-photo-32847.jpg."
The Legal Landscape
WCAG compliance is not just about doing the right thing — it's increasingly a legal requirement:
- United States: The ADA has been interpreted by courts to apply to websites. Accessibility lawsuits reached approximately 4,600 in 2023, up from 265 in 2016.
- European Union: The European Accessibility Act (EAA) requires products and services to meet accessibility standards from June 2025.
- United Kingdom: The Equality Act 2010 requires reasonable adjustments for disabled users.
- Canada: The Accessible Canada Act sets federal accessibility standards.
The industries with the strongest legal exposure — government and finance — also tend to score highest in our analysis. That correlation is not coincidental.
The Regulatory Divide
Our data reveals a clear pattern: regulated industries outperform unregulated ones.
| Category | Avg Score | Regulatory Pressure |
|---|---|---|
| Government | 88.3 | High (Section 508, EN 301 549) |
| Finance | 78.3 | High (ADA lawsuits, CFPB guidance) |
| Education | 90.0 | High (Section 504, OCR enforcement) |
| Healthcare | 76.3 | Moderate (Section 1557, HIPAA) |
| E-commerce | 73.3 | Moderate (ADA Title III lawsuits) |
| News & Media | 60.0 | Low |
| Social & Entertainment | 58.3 | Low |
When regulators require accessibility, organizations invest in it. When they don't, accessibility becomes a nice-to-have that rarely makes it past the backlog.
What This Means for Your Website
If Harvard can score 100 and BBC can score 60, the gap is not about resources — it's about priorities. The good news: the most common issues are also the easiest to fix.
Five Fixes That Cover the Most Ground
1. Fix your heading hierarchy. Audit your pages for heading-level skips. Every page should start with one H1, followed by H2s for major sections, H3s for subsections, with no gaps. This 15-minute fix addresses the most common issue in our dataset.
2. Add skip navigation. Insert an anchor link as the first focusable element on every page: <a href="#main" class="skip-link">Skip to main content</a>. Style it off-screen by default, visible on focus. This addresses an issue found on 50% of sites.
3. Ensure unique element IDs. Run a quick automated check for duplicates. Duplicate IDs break label-input associations and ARIA references — both critical for assistive technology.
4. Add alt text to every image. Use descriptive text for informational images and alt="" for decorative ones. Never leave the alt attribute absent entirely. BBC's 50% alt text failure rate shows even major organizations miss this basic requirement.
5. Don't block viewport zoom. Remove user-scalable=no and maximum-scale=1 from your viewport meta tag. Low-vision users rely on pinch-to-zoom to read content on mobile. Blocking it fails WCAG 1.4.4 and creates a genuine barrier.
Important Caveats
Our analysis covers automated static HTML checks only, which represent approximately 30-40% of WCAG 2.1 Level A criteria. Many important accessibility requirements — color contrast, keyboard operability, focus management, dynamic content updates, screen reader compatibility — require manual testing or browser-based evaluation.
Some sites in our sample (Reddit, Booking.com, Spotify, TripAdvisor) deliver minimal server-side HTML and rely heavily on client-side JavaScript rendering. Their actual accessibility may differ from what static analysis detects, for better or worse.
A passing score on automated checks does not mean a site is fully accessible. A failing score, however, reliably indicates real problems.

Methodology
This report analyzed homepage content for each website as of February 24, 2026. WCAG scores were generated using LLMSE's WCAG analyzer (v1.5.18), which performs 15 automated WCAG 2.1 Level A checks with deduction-based scoring (-15 per critical, -5 per warning, -1 per info).
The global distribution data (32,700+ URLs) comes from LLMSE's classification pipeline, which runs WCAG analysis automatically during URL processing. Individual site results in the 30-site sample were generated from fresh homepage fetches, not cached data.
Limitations: We analyzed homepages only. Subpages, application flows, and authenticated areas may score differently. Automated checks cover approximately 30-40% of WCAG 2.1 Level A — manual testing is required for full compliance assessment.
This analysis was conducted using LLMSE, which has classified over 1.4 million websites across SEO, EEAT, WCAG accessibility, readability, and GARM brand safety dimensions. All data reflects the database as of February 2026. To analyze your own site, visit llmse.ai/classify.
