Web accessibility affects billions of people who use the internet differently, including those using screen readers or keyboard navigation. This page walks through key barriers on real homepages—low-contrast text, unlabeled form elements, missing skip links, and missing text alternatives—so you can understand who is blocked and why. It also connects those issues to outcomes like task speed, engagement, and reduced legal risk.
Key Takeaways

- 96.3% of homepages have low-contrast text issues failing WCAG 1.4.3, affecting colorblind and low-vision users
- Screen reader users encounter unlabelled form elements on 70.6% of pages, violating WCAG 3.3.2 labels requirement
- Approximately 1 in 4 U.S. adults has a disability, with 61 million people aged 18+ living with disabilities that often impact internet usage
- Globally, over 1 billion people, or 15% of the world's population, experience some form of disability, many relying on web accessibility for daily tasks
- In the EU, 87 million people (16% of population) have disabilities, with visual impairments affecting 2.1% directly impacting web navigation

- Companies ignoring accessibility lose $6.9B annually in US from excluded disabled consumers with $200B spending power
- Accessible e-commerce sites see 137% higher customer retention rates for disabled users
