4.  Add Alt Text to Images

Alternative text (alt text) is essential for images, allowing screen readers to describe them to users.

Provide concise and descriptive alt text for content-enhancing images, and avoid using generic phrases like “image” or “picture.”

For decorative images, use an empty alt attribute (alt=””) to indicate that the image is not essential content.

5. Implement a Clear Link Strategy

A well-designed link strategy improves user experience and accessibility.

Describe links before inserting them, using descriptive text that indicates the link’s purpose.

Use visual cues like icons (e.g., PDF icons) to differentiate links from surrounding text.

Underline links to distinguish them further, and highlight menu links on mouseover to enhance usability.
