WCAG 2.2 Website Accessibility: A 2026 Compliance Guide for B2B Sites

Website accessibility for a B2B site means building to WCAG 2.2 Level AA, the W3C standard published in October 2023. The U.S. Department of Justice has no regulation setting detailed web standards for businesses, yet the ADA still covers their websites, and the European Accessibility Act has applied to e-commerce since June 2025.

Most sites miss the mark by a wide margin, and the gap got worse this year. The good news is that a handful of error types account for nearly all of it, and the fixes sit squarely inside normal web work: design tokens, form markup, component code and testing. This guide covers what changed, what the rules require, and where to start.

Website accessibility failures got worse in 2026

WebAIM's 2026 analysis of the top one million home pages found detectable WCAG 2 failures on 95.9 percent of them, up from 94.8 percent in 2025, with an average of 56.1 errors per page, a 10.1 percent increase (WebAIM Million). The most common problems were low-contrast text on 83.9 percent of home pages, missing image alt text on 53.1 percent, missing form labels on 51 percent, empty links on 46.3 percent, empty buttons on 30.6 percent and a missing document language on 13.5 percent. Those six categories made up 96 percent of all errors detected.

The audience affected is large. The CDC reports that more than 1 in 4 U.S. adults, over 70 million people, reported having a disability in 2022 (CDC). On a B2B site, an unlabeled demo form or an unreadable pricing table blocks a buyer at the exact step that produces pipeline, which is why accessibility belongs in any review of why a B2B website isn't converting.

WCAG 2.2 adds nine success criteria to the accessibility standard

WCAG 2.2 became a W3C Recommendation on 5 October 2023 and adds nine success criteria to WCAG 2.1 (W3C). Six of them sit at Level A or AA, the level most organizations target: Focus Not Obscured (Minimum), Dragging Movements, Target Size (Minimum), Consistent Help, Redundant Entry and Accessible Authentication (Minimum). The older 4.1.1 Parsing criterion is obsolete and removed.

Each one maps to a familiar B2B pattern. Sticky headers, chat launchers and cookie banners can hide the element a keyboard user has focused. Small icon buttons fail the new minimum target of 24 by 24 CSS pixels. Multi-step demo and signup forms that ask for the same details twice fail Redundant Entry, and login puzzles or CAPTCHAs that require memory or transcription can fail Accessible Authentication. A help link that moves around from page to page fails Consistent Help. Most of these are component fixes, the same layer where we tune responsiveness in our guide to Interaction to Next Paint.

ADA website compliance rests on guidance, deadlines and lawsuits

For private businesses, the Justice Department's guidance says the ADA's requirements apply to goods and services offered on the web, and that businesses have flexibility in how they comply because the department has no regulation setting out detailed standards. It points to WCAG and Section 508 as helpful guidance (ADA.gov). For state and local governments, a separate Title II rule sets dates, and an interim final rule in April 2026 pushed them back to April 26, 2027 for entities serving 50,000 people or more and April 26, 2028 for smaller ones (Federal Register).

Litigation fills the gap left by the missing private-sector standard. Law firm Seyfarth Shaw counted 3,117 website accessibility lawsuits filed in federal court in 2025, a 27 percent increase from 2024, making up 36 percent of all ADA Title III suits that year (Seyfarth Shaw ADA Title III blog). Its count excludes state courts, so the real number is higher. This article is general information; talk to counsel about your exposure.

The European Accessibility Act reaches companies selling into the EU

The European Accessibility Act entered into application on June 28, 2025, and the European Commission estimates around 100 million people in the EU live with a disability (European Commission). The products and services it covers include e-commerce, banking services and e-books, enforced through each member state's national law (European Commission).

For a U.S. company, the test is who you serve. A business that sells to consumers in the EU through its website falls within the e-commerce scope, wherever it is headquartered. Pure B2B services may sit outside it, but the boundary depends on the national rules, so confirm with counsel before deciding. Building to WCAG 2.2 AA covers the practical ground either way, since the European standard EN 301 549 incorporates the WCAG success criteria for web content.

Accessibility overlays fall short of WCAG compliance

One-line overlay scripts promise instant compliance, and regulators have pushed back. In January 2025 the FTC moved to require accessiBe to pay $1 million to settle allegations that it misrepresented the ability of its AI-powered tool to make any website WCAG compliant (FTC). The Justice Department's own guidance says automated checkers and overlays need to be used carefully, and that a clean report does not mean everything is accessible (ADA.gov).

Automated scans are still worth running, as long as you treat them as a first pass. WebAIM notes that the absence of detected errors does not indicate a page is accessible, and its data shows home pages with ARIA present averaged 59.1 errors against 42 on pages without it (WebAIM). WebAIM cautions that the comparison does not prove ARIA caused the errors. Even so, ARIA is a precision tool best used sparingly, and the durable fix is clean semantic HTML in your templates and components, checked by a person using a keyboard and a screen reader.

A WCAG 2.2 checklist your web team can run this quarter

Run an automated scan across your templates, then fix the six common errors at the component level: contrast in your color tokens, alt text in your CMS fields, labels on every form input, descriptive text on every link and button, and a lang attribute on every page. Next, tab through your homepage, pricing, demo form and contact page with no mouse, and check that focus stays visible and is never hidden behind sticky elements. Test the same flows with a screen reader, and add the WCAG 2.2 items: 24-pixel targets, no repeated form entries, a consistent help location and a login that does not depend on a memory test.

Then keep it fixed. Add accessibility checks to your release process, publish an accessibility statement with a contact for problems, and retest after every redesign. The W3C says the best way to prepare for the still-draft WCAG 3 is to meet WCAG 2.2 now (W3C).
