Alt Text
Alt text (alternative text) is a descriptive attribute added to images in HTML and other digital formats to provide a text alternative for users who cannot see the image, such as those using screen readers or in cases where images fail to load. It serves as a crucial accessibility feature that ensures content is perceivable by all users, including those with visual impairments, and also contributes to SEO by helping search engines understand image content.
Developers should implement alt text whenever they embed images in web pages, documents, or applications to comply with accessibility standards like WCAG and improve user experience for people with disabilities. It is essential in web development, content management systems, and any digital interface where images convey information, as it enhances inclusivity and can boost search engine rankings by providing context to crawlers.
