When building a website, accessibility and search engine optimization might seem like separate goals, but these elements are closely linked. An accessible website enhances everyone’s experience, including those with disabilities, while making it easier for search engines like Google to understand the content.

By prioritizing accessibility, you’re not only making your site more inclusive but also increasing its visibility online, as accessibility and SEO work together to create a user-friendly and discoverable site.

For business owners, web developers, marketers, and content creators, integrating accessibility with SEO offers a proactive way to reach a larger audience and establish a stronger digital presence.

Rather than treating accessibility as a standalone feature, embracing it as a core part of your SEO strategy reveals its power. Enhancing usability supports both individual users and signals to search engines that your website is designed to offer a quality experience.

Understanding Website Accessibility

Website accessibility is about designing your site so anyone can use it, including people who rely on assistive technologies such as screen readers, voice control, or keyboard-only navigation.

The Web Content Accessibility Guidelines (WCAG) are internationally recognized standards that outline how to make web content usable for everyone, structured into three levels: A, AA, and AAA. Meeting Level AA is widely regarded as best practice, balancing usability with a site’s overall design and functionality.

To make your site accessible, here are a few core principles:

  • Descriptive alt text for images allows screen readers to convey what the image shows to visually impaired users.
  • Color contrast between text and background ensures readability for people with low vision or color blindness.
  • Keyboard accessibility for interactive elements, like links, buttons, and forms, is essential for users with motor impairments.
  • Text alternatives, such as captions for videos and transcripts for audio, allow people with hearing impairments to access information.
  • Clear headings and labels improve navigation for those using screen readers.

By focusing on these elements, you’re creating a more inclusive site and enhancing its overall search engine ranking.

Real-World Business Impacts of Accessibility

Accessibility improvements can have a significant impact on businesses:

  • Tesco, a major UK retailer, collaborated with the Royal National Institute of Blind People to enhance accessibility on its online grocery platform. This redesign, which focused on screen-reader compatibility and intuitive navigation, resulted in a 350% increase in sales, growing from GBP 52 million to GBP 235 million within a year.
  • NHS Digital saw user engagement improve dramatically through accessibility-focused changes. By simplifying navigation and reducing redundant content, NHS increased daily users from 15,000 to 26,000, showing how accessibility can enhance engagement.
  • Domino’s Pizza faced a lawsuit concerning its website’s accessibility for visually impaired users. Although initially costly, this prompted Domino’s to revamp its online ordering system, making it screen-reader compatible. This case underscores the importance of proactive accessibility measures in avoiding legal risk and enhancing user experience.

How Accessibility and SEO Work Together

Accessibility and SEO share the goal of improving user experience, which search engines like Google highly value. Google rewards sites that are easy to navigate, and accessible design directly supports this by making sites functional for everyone.

Organized headings make content structure clear to both Google and screen readers, while descriptive alt text aids in accurate indexing of images. Simple, logical URLs enhance clarity for users and search engines alike, improving both accessibility and SEO.

SEO Benefits Beyond Rankings

The benefits of accessibility extend beyond higher search rankings:

  • Increased Shareability: Accessible and readable content is more likely to be shared on social media and linked back to by other sites, increasing organic backlinks. These organic references signal to search engines that your content is valuable, authoritative, and widely recognized, strengthening your site’s SEO.
  • Higher Return Visits: Users tend to return to accessible sites because they know they can easily navigate and access content without barriers. These return visits reinforce your site’s engagement metrics, which is a positive signal to search engines and further enhances your credibility.
  • Improved Engagement Metrics: An accessible website promotes a better overall experience, leading to higher time spent on pages, reduced bounce rates, and improved conversion rates. Clear navigation, readable fonts, and well-structured content make it easier for visitors to interact with and understand your site’s offerings, which improves both user satisfaction and SEO signals to search engines.

These recurring visits and shares are essential as they strengthen engagement metrics and further signal to search engines that your site is high-quality.

Tools for Maintaining Accessibility and SEO

Maintaining a website that is both accessible and SEO-friendly requires ongoing attention. Here are some valuable tools:

  • Google Search Console provides insights into user behavior, helping identify areas where accessibility can enhance engagement.
  • A/B testing can be applied to color schemes or font sizes to gather data on user preferences.
  • WAVE and Google Lighthouse help ensure compliance with accessibility standards, detecting issues like missing alt text, low contrast, or slow loading times.

Using these tools consistently can help keep your website accessible and visible to a broad audience.

Around the world, the legal landscape for digital accessibility is becoming more rigorous. In the United States, the Americans with Disabilities Act requires businesses to make online services accessible, while the European Union’s Accessibility Act mandates compliance by 2025. Countries like Canada, the United Kingdom, and Australia are also setting similar standards, underscoring a global move towards inclusive digital experiences.

Failing to meet these standards can lead to fines, legal action, and reputational damage, as companies have faced lawsuits for failing to provide accessible online content. By following these standards, businesses protect themselves from legal risk while aligning with SEO and accessibility best practices.

New trends are emerging at the intersection of accessibility and SEO. Voice search, for instance, is growing rapidly and demands content that is clear and concise, which is also fundamental to accessible design. As more people use virtual assistants like Siri and Google Assistant, websites optimized for voice search are likely to see increased engagement.

Artificial intelligence (AI) is another promising tool, capable of dynamically adjusting content presentation based on user needs. For instance, AI can help convert text to speech or simplify complex text, bringing personalization to accessibility and making it an even greater asset for SEO as search engines adapt to user-centric content.

Inclusive Design as a Core Brand Value

Inclusive design is becoming essential for many brands, showing a commitment to serving diverse audiences. Websites built with accessibility in mind demonstrate a brand’s respect for all customers, building trust and loyalty.

By focusing on inclusivity, businesses can attract customers who appreciate brands that prioritize accessibility. A clear, readable website shows that a brand values every visitor, creating a positive impression and fostering stronger customer relationships.

Common Misconceptions About Accessibility

Some misconceptions prevent businesses from fully embracing accessibility. For example, accessibility improvements are often seen as costly or relevant only to a small group of users. In reality:

  • Low-Cost Updates: Many updates, such as adding alt text or simplifying navigation, are low-cost and can be implemented gradually.
  • Universal Benefits: Accessibility benefits everyone, including mobile users, those in bright environments, and people with temporary impairments.

Recognizing the broad value of accessibility helps businesses embrace it as a priority alongside SEO.
