Does Achieving 100% AAA Accessibility Boost Your Website’s Search Engine Ranking?

In the digital age, website accessibility has transcended beyond being just a good practice; it’s a necessity. As web developers and content creators, we often hear about the importance of making websites accessible, specifically aiming for the coveted ‘100% AAA’ accessibility rating. But does achieving this gold standard in accessibility also enhance your website’s search engine ranking? Let’s dive into this intriguing topic.

What is AAA Accessibility?

Before we explore the impact on search engine rankings, it’s crucial to understand what AAA accessibility entails. In the world of web design, accessibility is governed by the Web Content Accessibility Guidelines (WCAG). These guidelines are divided into three levels of compliance: A, AA, and AAA, with AAA being the highest. Achieving 100% AAA accessibility means your website is accessible to the broadest range of users, including those with various disabilities.

The Connection Between Accessibility and SEO

Search Engine Optimization (SEO) is all about making your website more visible on search engines like Google. While Google doesn’t explicitly state that AAA accessibility improves search engine rankings, there’s an indirect relationship between accessibility and SEO.

  1. Enhanced User Experience: Search engines favor websites that offer a great user experience. An AAA accessible website is user-friendly, easier to navigate, and understandable for a wider audience, including those with disabilities. This can lead to lower bounce rates and higher engagement, both of which are favorable for SEO.
  2. Improved Site Structure and Navigation: Accessible websites typically have clear headings, logical structure, and effective navigation. These features not only aid users with disabilities but also help search engine crawlers understand and index your website more effectively.
  3. Increased Content Reach: By making your website accessible, you’re opening up your content to a broader audience, including those with disabilities. This can lead to more traffic, shares, and backlinks, which are vital factors in SEO.

The Myth of Direct Correlation

However, it’s essential to address a common misconception: there is no direct evidence that achieving 100% AAA accessibility automatically boosts your site’s search engine ranking. Search engines use a multitude of factors to determine rankings, and while accessibility is a component of a quality website, it’s not a standalone factor for SEO.

Best Practices for Balancing Accessibility and SEO

  1. Use Alt Text for Images: This not only aids visually impaired users but also allows search engines to better understand the content of your images.
  2. Ensure Text Readability: Using clear and straightforward language benefits all users and can improve your site’s readability score, a factor in SEO.
  3. Structured Data and Headings: Utilize proper heading tags and structured data to organize content, making it easier for both users and search engines to navigate your site.
  4. Loading Speed and Responsiveness: An accessible site should load quickly and be responsive across various devices, a factor that significantly impacts SEO.


In conclusion, while achieving 100% AAA accessibility does not directly boost your website’s search engine ranking, it contributes significantly to overall site quality, which is a critical component of SEO. By focusing on accessibility, you’re inherently improving many aspects of your website that search engines value. It’s a win-win situation: you create a more inclusive web experience while potentially enhancing your website’s visibility and reach.

Additionally, if users can read and use all of your website easily, they will stay for longer and share links to your website — which will directly improve it’s search engine performance. Making a website which is not so accessible is basically cutting off some people from being able to enjoy your content.
