Avoid These 7 Website Accessibility Errors to Improve Your Google Search Ranking

As Google increasingly favors accessible websites in its search rankings, ensuring your website meets the Web Content Accessibility Guidelines (WCAG 2.1) is crucial for both user experience and search engine optimization (SEO). In this article, we'll guide you through the seven common website accessibility errors and provide actionable advice to correct them.

A Strategic Cpluz Perspective

At Cpluz, we've found that a focus on accessibility is not just a moral obligation but also a sound business strategy. By incorporating accessibility into your web development and design process, you can expand your audience, enhance user experience, and potentially boost your search engine rankings.

1. Duplicate or Missing Alternative Text

Many websites neglect to provide alternative text for images, resulting in a lack of context for screen readers and other assistive technologies. To fix this, ensure that every image on your website has an accurate and descriptive alt attribute.

Example: A group of smiling children holding hands in a park.

Why it matters: Alternative text helps visually impaired users understand the content and context of your images.

2. Inaccessible PDFs

PDFs can be a challenge for accessibility if not properly formatted. Ensure that your PDFs include a title, headings, and tagged content. You can also provide alternative text for images within the PDF.

How to do it: Use a tool like Adobe Acrobat to add tags and alternative text to your PDFs.

Why it matters: Inaccessible PDFs can hinder users' ability to navigate and understand the content, negatively impacting your website's accessibility and SEO.

3. Insufficient Color Contrast

Aim for a minimum contrast ratio of 4.5:1 between the background and text to ensure that users with color vision deficiency can easily read your content. You can use online tools like the WebAIM Color Contrast Checker to test your website's color scheme.

How to do it: Use the color contrast checker to identify potential issues and adjust your design accordingly.

Why it matters: Inadequate color contrast can make your website difficult to navigate and read for users with color vision deficiency, leading to a poor user experience and potential penalties in search rankings.

4. Poor Navigation and Breadcrumb Trails

A well-structured navigation menu and breadcrumb trail are essential for users with screen readers and those using keyboard navigation. Ensure that your navigation is logical, consistent, and provides a clear wayfinding system.

How to do it: Implement a clear and consistent navigation menu, and use breadcrumbs to help users understand their current location within your website.

Why it matters: Poor navigation can confuse users, leading to frustration and potentially harming your website's SEO and user experience.

5. Flash Content

Flash content can be inaccessible to users with disabilities, and many devices no longer support it. Instead, use HTML5 alternatives for multimedia content.

How to do it: Convert any Flash content to HTML5, and use modern web technologies for animations and multimedia.

Why it matters: Flash content can hinder your website's accessibility and may cause issues with search engine crawlers, potentially impacting your SEO.

6. Keyboard Navigation Issues

Ensure that your website is fully navigable using a keyboard, as many assistive technologies rely on this functionality. Test your website using a keyboard-only navigation to identify any issues.

How to do it: Test your website using a keyboard-only navigation to ensure that all elements are accessible and can be reached via keyboard shortcuts.

Why it matters: Inaccessible keyboard navigation can prevent users with disabilities from fully using your website, leading to a poor user experience and potential SEO penalties.

7. Captchas

Captchas can be challenging for users with disabilities, as they often rely on visual or audio elements. Consider using alternative verification methods, such as email or phone number verification, to ensure that all users can access your content.

How to do it: Implement alternative verification methods to ensure that all users can access your content without relying on captchas.

Why it matters: Captchas can exclude users with disabilities from accessing your content, negatively impacting your website's accessibility and SEO.
