95.9%
of homepages had detected WCAG failures in WebAIM's automated test.
Up from 94.8% in 2025. A homepage without a detected error is not automatically conformant.

§ InsightsWeb accessibility
Web accessibility statistics for 2026.
The numbers below come from WebAIM's February 2026 automated scan of one million popular homepages. Automated testing catches only part of accessibility, so every finding is described as a detected error rather than proof of full WCAG failure or legal noncompliance.
19 sourced findings · 3 sections · Updated July 13, 2026
01One million homepages
Detected accessibility errors remain nearly universal.
WebAIM evaluated the rendered DOM of the top one million homepages. The scale matters, but the wording matters too: automated tools detect specific failures and cannot establish complete conformance on their own.
56.1M
distinct accessibility errors were detected across the one million homepages.

56.1
detected errors appeared on the average homepage, a 10.1% increase from 2025.

Element count rose 22.5% year over year.

02The recurring six
Six error types account for almost everything automated testing finds.
The same correctable failures dominate year after year: low contrast, missing alternatives and labels, and controls that have no usable name.
96%
of all detected errors fell into just six recurring categories.

03Structure & semantics
Images, headings, skip links, and ARIA show where implementation breaks.
Accessibility is not a plugin badge. It lives in the names, relationships, and document structure a person using assistive technology has to navigate.
66.6M
images appeared across the homepages in the sample.

16.2%
of all images were missing alternative text.

41.8%
of homepages skipped at least one heading level.

7.5%
had no headings at all.

17.1%
had a skip link, and about one in ten of those skip links was broken.

133.6M
ARIA attributes were detected, 27% more than in 2025 and roughly six times the 2019 count.
More ARIA does not automatically mean better accessibility; incorrect ARIA can create new barriers.

What this data does not prove
Automated testing is a floor, not a full audit. WAVE can detect many machine-testable failures. It cannot judge every keyboard path, announcement, meaning, focus sequence, or real task a human encounters.
Detected errors are not a legal verdict. This page does not determine ADA liability or WCAG conformance and is not legal advice. The DOJ rule linked below specifically addresses state and local governments.
Homepage findings do not describe every page. The study evaluates one homepage per domain. A checkout, form, patient portal, service page, or application can perform better or worse.
04FAQ
Common questions
What percentage of websites have accessibility errors in 2026?
WebAIM detected WCAG failures on 95.9% of the one million popular homepages it tested in February 2026. That is an automated homepage finding, not proof that 95.9% of full websites legally fail.
What are the most common website accessibility errors?
Low-contrast text, missing image alt text, unlabeled form inputs, empty links, empty buttons, and missing document language accounted for 96% of all errors WebAIM detected.
Can an accessibility widget make a website WCAG compliant?
No tool or badge can establish complete conformance by itself. Accessibility depends on the underlying content, semantic markup, interactions, forms, keyboard behavior, and ongoing publishing practices.
Does an automated scan prove ADA compliance?
No. Automated tools identify some technical issues; legal compliance requires context and qualified review. This page is research, not legal advice.
05Sources & method
WebAIM evaluated the rendered homepages with WAVE and publishes its method, definitions, and year-over-year comparisons. W3C is linked for the WCAG standard. The ADA source is included only to distinguish the Department of Justice's state-and-local-government rule from private-business obligations.

07Work with Campbell Digital Studio
Accessibility starts in the underlying build.
CDS treats semantic structure, keyboard behavior, labels, contrast, and mobile QA as build work. No badge can substitute for that foundation.
