In the fast-paced world of professional networking, alt text on LinkedIn plays a crucial role in making your posts accessible and discoverable.

Alt Text's Role in Digital Accessibility

Alt text—short for "alternative text"—was first introduced in HTML to display descriptions when images didn’t load. Today, it’s a core requirement in the Web Content Accessibility Guidelines (WCAG), benefiting everyone from those with visual impairments to users in low-bandwidth situations.

• Accessibility: Screen readers vocalize alt text to describe images to visually impaired users.
• Fallback Content: Alt text appears when images fail to load, preventing loss of context.
• Search Indexing: Search engines and internal LinkedIn algorithms can read alt text, potentially aiding discoverability.

How Alt Text Improves Accessibility for Screen Reader Users

Screen readers such as JAWS and NVDA transform text and metadata into speech or Braille. Alt text ensures:

• Clear identification of graphic content
• Conveyance of essential details
• Preservation of context and purpose in relation to the post

Without alt text, an image may simply be announced as “image” with no meaningful information, reducing user experience.

• Increase engagement and reach through accessible posts
