Definition

Alt text, or alternative text, is a descriptive text that is added to images on websites, serving as a textual substitute for the visual content. It plays a crucial role in making web content accessible to users with visual impairments who rely on screen readers, as well as improving search engine optimization by providing context for images. Alt text enhances the overall user experience by ensuring that all visitors can understand and engage with the content, regardless of their abilities or the devices they are using.
