How to Fix Images Without Alt Text in WordPress

Missing alt text might seem minor, but it can significantly affect your website’s SEO and accessibility. Alt text (short for “alternative text”) describes the content of an image, which is helpful for search engines and crucial for users who rely on screen readers.

If your WordPress images don’t include alt attributes, you're missing out on both usability and visibility.

Why Alt Text Matters

- Accessibility: Helps visually impaired users understand what’s in an image.
- SEO: Search engines use it to understand and index your image content.
- Image search visibility: Well-written alt text can get your images ranked in Google Images.
- Fallback context: If the image doesn’t load, users will still understand what was intended.

How to Identify Images Missing Alt Text

1. Manually Check in the Media Library
  - Go to Media > Library
  - Click each image and look for the “Alternative Text” field

2. Use a Plugin
  - Accessibility Checker or WP Accessibility can help detect missing alt attributes across your site.
  - Yoast SEO or Rank Math also alert you if an image in a post lacks alt text.

3. Scan with Online Tools
  - Tools like WAVE Web Accessibility Evaluation Tool and axe DevTools let you check a page for accessibility issues, including images missing alt text.

Tips for Writing Good Alt Text

- Be descriptive but concise (e.g., “Golden retriever puppy running in a field”)
- Don’t use “image of” or “picture of”—it’s already understood
- Include context or function if the image is linked (e.g., “Download RDPCore brochure PDF”)
- Avoid keyword stuffing—write for clarity and relevance

Fixing Alt Text in Bulk (Optional)

If you have hundreds of images:

- Use Media Library Assistant or Auto Image Attributes From Filename With Bulk Updater to generate or edit alt text quickly
- Always review automated results to ensure they’re relevant and accessible

Final Thoughts

Every image should have alt text. It’s one of the simplest and most effective ways to improve your site's SEO, accessibility, and overall user experience. Make it a habit going forward—and audit old posts to clean things up!
