Why Checking Image Alt Text Matters for SEO and Accessibility

Image alt text (alternative text) is a crucial HTML attribute applied to image tags. It’s important for several reasons:

  • **SEO:** Alt text helps search engines understand the content and context of your images, which can contribute to image search rankings and overall page relevance.
  • **Accessibility:** Screen readers use alt text to describe images to visually impaired users, making your website accessible to a wider audience.
  • **User Experience:** If an image fails to load, the alt text is displayed in its place, providing context to the user.

Missing or poorly written alt text can hinder both your site’s SEO performance and its usability for people with disabilities. This tool helps you quickly audit your images for missing or empty alt attributes.
