A Step-by-step Guide to Auditing Your Website’s Existing Alt Text

Alt text, or alternative text, is a crucial component of web accessibility. It helps users with visual impairments understand the content of images on your website. Regularly auditing your alt text ensures that your site remains accessible and SEO-friendly. This guide walks you through a step-by-step process to review and improve your existing alt text.

Why Auditing Your Alt Text Matters

Proper alt text enhances user experience for visitors who rely on screen readers. It also contributes to your website’s search engine optimization (SEO), as search engines use alt text to understand image content. Incomplete or inaccurate alt descriptions can hinder accessibility and reduce your site’s visibility.

Step 1: Gather a List of All Images

The first step is to compile a comprehensive list of all images on your website. You can do this manually or use tools like Screaming Frog, Google Search Console, or accessibility audit plugins. Having a complete inventory ensures no image is overlooked during the audit.

Step 2: Review Existing Alt Text

Examine the current alt text descriptions. Look for:

  • Missing alt text
  • Vague or generic descriptions (e.g., “image” or “photo”)
  • Irrelevant or inaccurate descriptions
  • Overly long or keyword-stuffed text

Step 3: Evaluate and Edit Alt Text

Ensure each alt text accurately describes the image’s content and function. Follow these best practices:

  • Be specific and concise.
  • Use relevant keywords naturally.
  • Avoid keyword stuffing.
  • For decorative images, use empty alt attributes (alt="").

Step 4: Test Accessibility

Use screen reader tools or accessibility testing software to verify that your alt text effectively conveys the image content. This step helps identify issues that may not be obvious during manual review.

Step 5: Implement Changes and Monitor

Update your website with the improved alt text. Regularly monitor your site’s accessibility and SEO performance. Consider scheduling periodic audits to maintain optimal accessibility standards.

Conclusion

Auditing your website’s alt text is an ongoing process that ensures your content remains accessible and search-engine friendly. By following these steps, you can improve user experience for all visitors and demonstrate your commitment to inclusive web design.
