Social Media Post Alt Text

Social media post alt text is a written description that helps people using screen readers understand meaningful visual content shared in a post. A cleaning company posting a before-and-after image could describe the visible change without claiming results the photo cannot demonstrate. Good alt text prioritizes useful information over lists of search keywords and avoids repeating a caption word for word when that adds no value. Platform support for editing descriptions varies by format and interface. This is related to website image alt text, but the social publishing workflow and available fields can be different. Important announcements should not exist only inside an image.
