More than one in four U.S. adults have a disability, and about three‑quarters of disabled adults use the internet daily. Many of your potential customers therefore rely on tools like screen readers or keyboard navigation. A 2025 WebAIM study found that over 94 % of websites contain accessibility errors, particularly low contrast text and missing alt text. For small businesses, these issues can drive people away and invite legal scrutiny. The good news is that basic improvements are straightforward. This article outlines key accessibility principles and practical steps to make your site inclusive.
Making your website accessible isn’t only about meeting regulations; it’s about welcoming everyone. The Americans with Disabilities Act (ADA) requires businesses open to the public to provide equal access. Millions of adults have difficulty using a mouse or keyboard or have visual or hearing impairments, and many abandon inaccessible sites Beyond compliance, accessible design improves navigation and usability for everyone. In short, it’s both ethical and practical.
Low contrast text makes reading difficult for people with low vision or color blindness and is the most common web accessibility error. Section508 guidelines recommend a contrast ratio of at least 4.5:1 for body text and 3:1 for large text. You should also avoid using color alone to convey information; combine colors with text or icons so that users who cannot perceive color still understand your message To check your colors, use free online contrast testers and adjust your palette until it meets the ratios. Dark text on a light background or vice versa generally works well, and adding labels or shapes to charts makes them easier to interpret.
Images need alternative text (alt text) so screen reader users understand what they depict. Unfortunately, missing alt text remains a common failure. Good alt text briefly describes the image’s purpose and information. Section508 guidance emphasises that alt text should convey the same information as the image, avoid redundancy and be concise For decorative images that do not add information, use an empty alt attribute (alt="") so screen readers skip them. For example, describe “Bakery owner handing a croissant to a smiling customer” rather than “company photo.” Effective alt text not only improves accessibility but also helps search engines index your images.
Clear structure benefits all visitors. The W3C recommends using short headings to group related paragraphs and provide an outline of the page. Heading tags (H1 through H6) create a hierarchy that screen readers use to navigate. An H1 should represent the page title, with H2s for major sections and H3s for subsections. Styling text with bold or large fonts is not enough; proper HTML markup is required. Review your pages for a single, descriptive H1 and break longer sections into logical subheadings. This makes your content easier to scan and allows users to jump directly to what they need.
Many people use keyboards or other input devices instead of a mouse. WebAIM highlights that keyboard accessibility is crucial. Users tab through interactive elements using the Tab key and go backwards with Shift+Tab. Ensure every link, button and form field can receive keyboard focus and that a visible focus indicator (typically an outline) is visible. Avoid CSS that removes outlines (outline:0 or outline:none) and maintain a logical tab order that follows the visual layout. Provide a “skip to main content” link at the top so keyboard users can bypass large menus. A quick way to test: navigate your site using only the keyboard. If you can’t tell where you are or get stuck, adjustments are needed.
Forms are where conversions happen. Missing or ambiguous labels can frustrate users and lead them to abandon your site. According to WebAIM, nearly half of websites lack proper labels for form inputs. The W3C’s guidance states that every form control should be clearly labelled using the <label> element with an explicit for attribute. This tells screen readers what each field is for. Include concise instructions near the field rather than hiding requirements in error messages. Indicate required fields with text (and if you use an asterisk, explain what it means). If a user makes an error, highlight the field and provide clear guidance on how to fix it. Thoughtful forms make it easy for everyone to contact you or complete a purchase.
Videos can exclude people who are deaf or hard of hearing. Section508 notes that captions provide a textual display of dialogue and important sounds, and WCAG requires captions for pre‑recorded and live media. Provide transcripts for audio-only content. Captions and transcripts also help users in noisy environments. Most video platforms offer automated captions; review them for accuracy and add a transcript for podcasts or audio clips.
Accessibility isn’t a one‑time task. The ADA recommends combining manual and automated testing. Tools like the WAVE extension catch many issues, but human judgement is essential. Navigate your site with a screen reader and keyboard, and ask disabled users for feedback. Offer a way for visitors to report issues so you can fix them. Regular checks and small fixes help maintain an inclusive experience.
If you’re planning a redesign or new site, incorporate accessibility early. Choose templates or themes known for good accessibility, and prioritize responsive design so content adapts to different screen sizes. Use relative units like rem or em to allow text scaling. The W3C emphasizes keeping content clear and concise and using meaningful link text (avoid “click here”). Planning for accessibility from the start saves time and reduces the need for expensive retrofits later.
While legal requirements provide one motivation, accessibility also makes financial sense. WebAIM’s analysis found an average of 51 accessibility errors per homepage. Resolving these issues expands your market to the roughly 28 % of adults with disabilities and improves the experience for everyone. Accessible sites tend to be faster and rank higher in search results, which can increase conversions. Enforcement is also increasing: in 2024 the Department of Justice finalized a rule requiring state and local governments to meet WCAG 2.1 Level AA for their websites and mobile apps. Although this rule applies to public entities, it signals a broader trend toward clear standards. Taking action now demonstrates social responsibility and may give your business a competitive advantage.
Accessibility is both a moral obligation and a practical investment. By implementing a few fundamental practices—improved color contrast, descriptive alt text, structured headings, keyboard-friendly navigation, clear form labels, captioned media and regular testing—you can make your website more inclusive without significant cost. These adjustments enhance user experience, broaden your audience and help your business stand out for the right reasons.
