Why Alternative (Alt) Text Is Important
Alt text is read by screen readers to convey the purpose or content of images to visually impaired users. It also helps search engines understand your images and boosts SEO.
When alt text accurately reflects what is shown or conveyed by an image, all users can more fully engage with your site’s content. We can discriminate three kinds of images:
1. Regular (Informative) Images
For images that communicate essential information, write a concise sentence describing the main subject and context.
Tip: Focus on what’s truly important in the image. You don’t need every detail—just what matters to understanding the content.

2. Hero/Logo Images
If the image is a hero banner or logo that includes text crucial to the content—such as an event name, company slogan, or brand information—use the visible text for the alt attribute.
Tip: Only include the text that users need to know. Don’t repeat text that is already displayed nearby in plain text on the page.

3. Decorative Images
For purely decorative images that add visual flair but provide no additional information: Mark them as “decorative” -> this tells assistive technology that the image can be safely ignored.
Tip: If removing the image wouldn’t change a user’s understanding of the page, it’s decorative.
