Creating Consistent Alt Text Guidelines for Your Content Team

by

Creating effective and consistent alt text guidelines is essential for ensuring that your website is accessible to all users, including those with visual impairments. Clear guidelines help your content team produce descriptive, concise, and useful alt text for images across your site.

Why Alt Text Matters

Alt text provides a textual description of images for screen readers and improves SEO. When alt text is inconsistent or missing, it can hinder accessibility and reduce the overall quality of your website. Establishing standardized guidelines helps maintain high accessibility standards and ensures a uniform user experience.

Key Components of Alt Text Guidelines

  • Descriptive and Concise: Alt text should accurately describe the image without being overly verbose. Aim for 125 characters or less.
  • Contextually Relevant: Tailor descriptions to the content’s purpose and how the image relates to the surrounding text.
  • Avoid Redundancy: Do not include phrases like “image of” or “picture of” as screen readers already identify images as such.
  • Decorative Images: Use empty alt attributes alt="" for purely decorative images to avoid cluttering screen readers.
  • Consistent Terminology: Use the same terms and style throughout your site to maintain professionalism and clarity.

Implementing the Guidelines

To ensure consistency, provide your content team with written guidelines, examples, and training. Regularly review and update these standards as your website evolves. Consider creating a checklist for writers and editors to follow when adding or updating images.

Tools and Resources

  • Accessibility Plugins: Tools like WAVE or Axe can audit your site for alt text issues.
  • Style Guides: Develop a style guide that includes alt text standards and best practices.
  • Training Sessions: Host workshops or tutorials to educate your team on accessibility and alt text creation.

By establishing and enforcing consistent alt text guidelines, your content team can improve the accessibility and professionalism of your website. Clear standards foster better communication and ensure all users have a positive experience.
