Between 2026-07-17 and 2026-07-17, an automated WCAG check scanned 429 websites. 52.1% of 326 sites fell in F, the lowest grade band with at least 10 sites. The sample is the home pages of 429 websites from two research sets built from a target list for the German market: online shops, transport and travel, banking and insurance, telecoms, football clubs, automotive, public-sector bodies and other organisations. A group is the label on our target list, not a finding that any law applies to a site. Most common detected failure mapped to a WCAG success criterion: Insufficient colour contrast (color-contrast), 88.0% of 326 sites. Second: Links with no discernible text (link-name), 34.0% of 326 sites. These are detected failures of an automated check in aggregated data, not a verdict on any site.

Three numbers

52.1% of 326 sites in the grade breakdown fell in F, the lowest grade band with at least 10 sites. Scans from 2026-07-17 to 2026-07-17.
88.0% of 326 sites in the rule breakdown had a detected failure of the most common rule mapped to a WCAG success criterion: Insufficient colour contrast (color-contrast). Scans from 2026-07-17 to 2026-07-17.
34.0% of 326 sites in the rule breakdown had a detected failure of the second most common rule mapped to a WCAG success criterion: Links with no discernible text (link-name). Scans from 2026-07-17 to 2026-07-17.

Method

The sample is 429 websites, scanned between 2026-07-17 and 2026-07-17. The scanner loaded each site in Chromium and ran an automated check (WCAG 2.1 Level A and AA, the WCAG 2.2 target size criterion 2.5.8, and axe-core best-practice checks) with axe-core 4.12.1. Sites that did not render are not assessed: they have no grade and no rule result, so the grade and rule tables have smaller denominators. Automated testing catches roughly 30 to 40 percent of WCAG success criteria, not 30 to 40 percent of a site's failures. We publish aggregates only. The minimum cell size is 10 sites, and no site is named.

Detected failures by criterion

Detected failures by axe-core rule and WCAG success criterion, sorted by share of sites. Denominator: 326 sites. A site can appear in several rows.
Check	Rule ID	WCAG success criterion	Sites	Share of sites with a detected failure
Insufficient colour contrast	`color-contrast`	1.4.3 Contrast (Minimum)	287	88.0%
Links with no discernible text	`link-name`	4.1.2 Name, Role, Value	111	34.0%
Images without alternative text	`image-alt`	1.1.1 Non-text Content	62	19.0%
Buttons with no discernible text	`button-name`	4.1.2 Name, Role, Value	46	14.1%
ARIA roles missing required child roles	`aria-required-children`	1.3.1 Info and Relationships	29	8.9%
Incorrectly structured lists	`list`	1.3.1 Info and Relationships	28	8.6%
Page disables zoom	`meta-viewport`	1.4.4 Resize Text	28	8.6%
Nested interactive controls	`nested-interactive`	4.1.2 Name, Role, Value	27	8.3%
ARIA attribute not allowed on this role	`aria-allowed-attr`	4.1.2 Name, Role, Value	22	6.7%
Form fields without a label	`label`	4.1.2 Name, Role, Value	20	6.1%
ARIA roles missing the required parent role	`aria-required-parent`	1.3.1 Info and Relationships	15	4.6%
List items without a parent list	`listitem`	1.3.1 Info and Relationships	13	4.0%
ARIA attribute with an invalid value	`aria-valid-attr-value`	4.1.2 Name, Role, Value	12	3.7%
ARIA commands without an accessible name	`aria-command-name`	4.1.2 Name, Role, Value	11	3.4%

ARIA input fields without an accessible name	`aria-input-field-name`	4.1.2 Name, Role, Value	11	3.4%
ARIA attribute prohibited for this element	`aria-prohibited-attr`	4.1.2 Name, Role, Value	11	3.4%

Grade bands

Sites by grade band, in grade order A to F. Denominator: 326 sites. The grade band is Inkluso's score out of 100 for the automated check: A from 90, B from 75, C from 60, D from 40, F below 40. A grade band is not a WCAG conformance level, and a high grade means the automated check detected few failures, not that a site is accessible.
Grade band	Sites	Share of sites
A	19	5.8%
B	40	12.3%
C	35	10.7%
D	62	19.0%
F	170	52.1%

Sites by country

Sites by country. Denominator: 429 sites. Country is the jurisdiction recorded for the scan, otherwise the language of the scan; it is not a finding about where a site's operator is based. Countries below the minimum cell size are left out.
Country	Sites	Share of sites
DE	429	100.0%

Sets

Sites by source set. Denominator: 429 sites. A site in both sets is counted in each, so the rows can add up to more than the denominator.
Set	Sites	Share of sites
scan-database	390	90.9%
scan-database-rerun	50	11.7%

Sites by group

Sites by target-list group. Denominator: 429 sites. Each site counts in one group; the table shows the number of scanned sites and their share of the sample, no outcome figure for any group, and groups with fewer than 10 sites are not listed.
Group	Sites	Share of sites
Online shops	236	55.0%
Transport and travel	63	14.7%
Banking and insurance	62	14.5%
Telecoms	19	4.4%
Football clubs	18	4.2%
Automotive	12	2.8%
Public-sector bodies	10	2.3%

What this data does not show

It does not show a manual test. Every result comes from an automated check, which covers only part of WCAG.
It covers only the home page of each site, as the scanner loaded it. No other page of any site was checked.
It does not show whether any site meets a national act or any other legal requirement. A detected failure of an automated check is not a legal conclusion about a site.
It is not a representative sample of all websites. The sample is the sets listed above.
20 cells with fewer than 10 sites are left out, so the tables do not add up to every site in every dimension.
