About
The Open Graph image alt tag provides alternative text for the image specified in the Open Graph protocol. This helps improve accessibility for users with visual impairments, as screen readers can describe the image content. Additionally, providing alt text ensures that the content of the image is still conveyed in cases where the image cannot be loaded or viewed, contributing to a better user experience and broader reach.
Why it's important
