Website Accessibility Checklists for 2025

Heading Structure

Your website should be well-organised with a proper heading structure. When you use HTML heading elements correctly, such as H1, H2, and H3 headings, it allows screen reader users to understand the layout, navigating your content effectively.

This structure establishes hierarchy. Screen readers rely on these headings to navigate content, enabling the visitor to jump to the sections they are interested in.

Pros:

• Improved navigation
• Enhanced SEO
• Improved Scanning

Image ALT Text

You also need to take your visitors with visual impairments into consideration when it comes to your website accessibility. Alternative text, or alt text, provides a description of the image, which is read aloud by screen readers, enabling visitors to understand the context and purpose of the images. It can also benefit any visitors with a slow internet connection where the images fail to load.

Your alt text should be descriptive, yet concise. It should convey important information presented in the image.

Pros:

• Necessary for accessibility
• Improved user experience 
• SEO benefits

Colour Contrast

It's important to ensure your website has sufficient colour contrast, ensuring your text and any interactive elements stand out clearly against background colours. This is important for any website visitors with poor vision or colour blindness. By implementing sufficient colour contract, you ensure your content is understandable for your audience, improving user experience, while aligning with accessibility best practices.

Pros:

• Improved readability
• Helpful for those with declining or poor vision
• Ensures content is accessible in all lighting conditions

Responsive Design with Text Resizing

A responsive design has become an essential part of an effective SEO strategy, but text resizing is just as important. This ensures your website adapts to different screen sizes, and when implemented correctly, it allows users to increase the text size. This ensures users with low vision, along with those accessible your website on their mobile device, can engage with your content effectively.

Pros:

• Improved user experience
• Improved mobile experience 
• Future proofing your website

Semantic HTML

Semantic HTML directly addresses how users with disabilities navigate and understand your website structure. It provides a roadmap for assisted technologies. This provides website visitors with the opportunity to jump between different sections, understanding the layout. 

Pros:

• Improved navigation for users relying on screen readers
• Improves SEO, as search engines also rely on semantic HTML to understand the context of your content
