In the context of web accessibility, "alt text" refers to alternative text that describes images for users who cannot see them. This description serves a crucial function for individuals using screen readers, which convert text to speech. By providing a brief but informative description of an image, alt text ensures that people with visual impairments can understand the content and context of the images on a webpage.

This practice aligns with accessibility standards, which aim to create an inclusive online environment. Including accurate and meaningful alt text is an essential aspect of web design, as it enhances the overall user experience for those with disabilities. For example, if an image depicts a beautiful landscape, the alt text might describe the scenery, allowing visually impaired users to share in the experience.

In contrast, the other provided options do not align with the core function of alt text. While text that improves search engine optimization, provides user instructions, or summarizes web content might contribute to a well-designed website, none of these options fulfill the specific purpose of making visual content accessible to users with visual impairments.
