Why prioritize web accessibility? 8 reasons for businesses

You should prioritize web accessibility because a site that people with disabilities can't use loses customers, leads and trust, and in a growing number of markets it also creates legal risk. The same fixes usually make the site easier for everyone and help search engines understand it.

Web accessibility means designing and building a site so that people with visual, hearing, motor, cognitive or neurological disabilities can use it. The standard most organisations follow is the W3C's Web Content Accessibility Guidelines (WCAG). The current version, WCAG 2.2, has three conformance levels (A, AA and AAA) and is backwards compatible with WCAG 2.1.

Here are eight reasons to make it a priority.

1. Is web accessibility the right thing to do?

Yes. Ramps, lifts and braille signs are normal in buildings. Online, many sites still lock people out: a form that can't be completed without a mouse, a video without captions, a button a screen reader announces only as "button".

Building an accessible site means nobody needs help from someone else to buy from you, book a demo or read your content. Accessibility also helps people in temporary or situational limits, such as a broken arm, a noisy train or bright sunlight on a phone screen.

2. How many more people can you reach?

A lot. The CDC says more than 1 in 4 US adults have some type of disability. Worldwide, the World Health Organization estimates that 1.3 billion people, about 16% of the population, experience significant disability.

These customers have money to spend and leave when a site gets in their way. The UK's Click-Away Pound Survey estimated that retailers lost £17.1 billion in 2019 because disabled shoppers left websites with accessibility barriers, up from an estimated £11.75 billion in 2016.

For B2B companies the logic is the same. Buyers, users and decision makers with disabilities work at the companies you sell to. If they can't use your site, they can't champion your product.

3. Does accessibility help SEO?

It overlaps with SEO in useful ways, though Google does not call accessibility a ranking factor.

• Alt text. Google says it uses alt text, together with computer vision and page content, to understand what an image shows, and notes that alt text also improves accessibility. See alt attribute.
• Captions and text near images and media. Google takes information from captions and surrounding text. Captions and transcripts also make video and audio usable for deaf and hard-of-hearing visitors, which WCAG requires.
• Clear structure. Real headings, descriptive link text and a logical page order help screen reader users and also help crawlers make sense of a page.

Treat the SEO benefit as a bonus. Do the work for people first.

4. Does it improve your brand's reputation?

It can. Visible care for accessibility shows customers and employees that your company takes inclusion seriously, and the reverse is also true when a site plainly excludes people.

A simple way to show your commitment is an accessibility statement. The W3C recommends it include your commitment, the standard you follow (such as WCAG 2.2) and contact details for reporting problems. Known limitations and the steps you are taking are also worth listing. The W3C offers a free statement generator.

5. Does it reduce legal risk?

Yes, and the risk is growing.

• United States. The Department of Justice says the ADA's requirements apply to all the goods and services that businesses open to the public offer, including those offered on the web. It has no detailed technical regulation for these businesses but points to WCAG as helpful guidance. Law firm Seyfarth Shaw counted 3,117 website accessibility lawsuits filed in federal court in 2025, up from 2,452 in 2024, and notes that state court cases and demand letters are not included.
• European Union. The European Accessibility Act applies to products and services placed on the market after 28 June 2025. Covered services include online shops, ticketing platforms and banking. Service businesses with fewer than 10 employees and under 2 million euros in turnover are exempt.

Rules differ by country and sector, so check what applies to you with a legal adviser.

6. Does it make the site easier for everyone?

Yes. Accessibility and user experience overlap heavily. WCAG requires that all functions work with a keyboard. Meeting that forces a clear, logical navigation order, which helps every visitor.

Other examples: good colour contrast helps people reading on a phone outdoors, captions help people watching without sound, and clear form labels reduce errors for all users. For more on why this matters, see the importance of UX.

7. Is web accessibility achievable for small teams?

Yes, but not with a one-click fix. Most problems are common and easy to fix once you know where to look. The WebAIM Million 2026 report, which tests the home pages of one million websites, found detected WCAG failures on 95.9% of them, with an average of 56.1 errors per page. The most common problems were:

WebAIM says 96% of all the errors it detected fall into these six categories. Its report also points out that automated tools cannot detect every failure.

Be careful with overlays and widgets that promise instant compliance. In April 2025 the Federal Trade Commission finalised an order requiring accessiBe to pay 1 million dollars. The FTC said the company's claims that its AI widget could make any website WCAG compliant were false, misleading or unsubstantiated. The W3C makes the general point: evaluation tools can assist, but they cannot determine accessibility, and some checks need human judgement. Combine automated scans with manual testing using only a keyboard and a screen reader.

8. Does accessibility lead to better code?

Usually. Accessible sites rely on semantic HTML: real buttons instead of clickable divs, proper headings, labelled form fields and text instead of images of text. That kind of code is easier to maintain, works better across browsers and assistive technology, and gives search engines a clearer picture of the page.

Where should you start?

1. Run an automated check on your key pages: home, pricing, sign-up and demo forms.
2. Fix the common issues in the table above.
3. Try to complete your main conversion path using only the keyboard.
4. Add captions to videos and alt text to informative images.
5. Publish an accessibility statement with a way to report problems.
6. Build accessibility into design and content reviews so new pages don't add new problems.

Accessibility isn't a one-off project. Treat it like security or performance: something every release keeps in mind.
