ImageSEO Reviews WebAIM 2026 Data: 53.1% of Top Home Pages Have Images Missing Alt Text as DOJ Deadlines Near

Top home pages now average 66.6 images, and 16.2% lack alternative text. The DOJ rule for larger state and local governments applies April 26, 2027.

DALLAS, TX, UNITED STATES, November 9, 2026 /EINPresswire.com/ -- ImageSEO, a WordPress plugin that writes image alt text and filenames, has reviewed the 2026 WebAIM Million report alongside its own audit of top-ranked homepages. WebAIM found images with missing alternative text on 53.1% of the top one million home pages, making it the second most common accessibility failure after low-contrast text.

Pages are carrying more images than before. WebAIM counted an average of 66.6 images per home page, up 13.6% in one year, and 16.2% of those images, or 10.8 per page, had missing alternative text. Across all error types, 95.9% of home pages had detected WCAG 2 failures, up from 94.8% in 2025, and the average rose to 56.1 errors per page from 51.

ImageSEO's July 2026 audit used a narrower sample and a stricter test. It analyzed 306,634 images on 5,306 reachable homepages from the 10,000 highest-ranked domains on the Tranco list. Of those images, 67.7% had non-empty alt text, 21.0% used alt="" and 11.3% had no alt attribute at all. At least one image with no alt attribute appeared on 37.1% of the sites, while 24.3% of sites described every homepage image. The two studies measure different things and are not directly comparable.

An empty alt attribute is not automatically an error. The W3C's Web Accessibility Initiative says decorative images should use a null alt value so that screen readers can ignore them. Images that carry information need a text description.

The issue also has a public-sector deadline in the United States. The Department of Justice's web accessibility rule under Title II of the Americans with Disabilities Act covers state and local governments. An interim final rule published April 20, 2026 moved the compliance date to April 26, 2027 for entities with a population of 50,000 or more, and to April 26, 2028 for smaller entities and special district governments. The department's own explanation of the rule uses an image without alt text as an example of content that a screen reader cannot convey.

"Automation can close a gap this size, but it cannot decide what an image means on a particular page," said the ImageSEO team. "A person still has to check that the description is right."

ImageSEO generates alt text and filenames for images in WordPress media libraries. A free plan covers 10 images per month with no credit card. The full audit data is at https://imageseo.io/alt-text-study/.
