WebAIM tests one million home pages: this is how accessible we will be in 2025
The WebAIM Million report examined how accessible 1,000,000 home pages on the internet are. This survey is done every year by WebAIM (Web Accessibility in Mind). They look at common problems that make it difficult for people with disabilities to use websites.
Comparison: 2024 and 2025
In February 2025, researchers found 50,960,288 errors on websites. That means an average page had 51 errors. This is 10.3% less than in 2024, when a page had an average of 56.8 errors.
This is an improvement, but there are still many websites that are not properly accessible.
| Year | Average number of faults per page |
|---|---|
| 2024 | 56.8 |
| 2025 | 51.0 |
It is good news that there are fewer errors than last year. But there are still millions of problems that make it difficult for people with disabilities to use websites.
Moving in the right direction
In 2019, errors were found on 97.8% of all websites, in 2024 it was 95.9%. A decrease of 1.9% in 5 years. But: in 2025, it was 94.8% - a drop of 1.1% in 1 year! That seems little, but is suddenly a substantial improvement in 1 year. If that continues...
Websites are becoming increasingly complex
The study shows that websites are becoming increasingly complex. In 2024, an average homepage had 1,173 elements. By 2025, that will have risen to 1,257 elements (+7.1%). Over the past six years, the number of elements has actually increased by 61%.
This is because more and more interactive and visual elements are being added. But the more elements a page has, the higher the risk of errors.

Common accessibility errors
About 4.1% of all elements on a website have an accessibility problem. This means that people with disabilities encounter an error on 1 out of 24 elements.
This table shows which errors are most common.
| Type of accessibility error (WCAG 2.2) | % of home pages |
|---|---|
| Low colour contrast | 79,1% |
| Missing alternative text for images | 55.5% |
| Missing labels for form entry | 48,2% |
| Empty links | 45,4% |
| Empty buttons | 29,6% |
| Missing document language | 15,8% |
Conclusion?
Although the average number of errors per page is decreasing, accessibility problems continue to arise. The increasing complexity of web pages makes it harder to solve these problems effectively.
To make the web more accessible, developers, designers and companies must continue to invest in accessibility improvements and adhere to international guidelines such as WCAG (Web Content Accessibility Guidelines).
