Adding descriptive text to images on Facebook provides context and accessibility. These additions, often called descriptions or labels, clarify the content of an image, offering viewers additional information. For example, a user might append a description to a photograph of a landmark detailing its location and historical significance.
The inclusion of text with visual content enhances user engagement and reach. Such additions improve the discoverability of images through search functionality. Furthermore, providing descriptions ensures content is accessible to individuals using screen readers, complying with accessibility guidelines and expanding the audience.
