Alt Text

Alt text (Alternative Text) is a brief image description for screen readers and SEO.

Alt text (alternative text) provides more accessibility to your images. It  is a brief description of an image that helps screen readers convey the content to visually impaired users and improves search engine optimization (SEO) by providing context to the image.

What are Alt Text best practices?

Here are some Alt text best practices, tips and tricks:

  1. Be Descriptive and Specific: Clearly describe the content and function of the image. Include details that convey the image’s purpose.
  2. Keep It Concise: Aim for 125 characters or fewer. Long descriptions can be cumbersome for screen reader users.
  3. Use Relevant Keywords: Include important keywords that are relevant to the image content for SEO purposes, but avoid keyword stuffing.
  4. Avoid Redundancy: Don’t start with phrases like “image of” or “picture of.” Screen readers already announce it as an image.
  5. Context Matters: Tailor the alt text to fit the context in which the image appears. Describe what’s important in the context of the surrounding content.
  6. Functional Images: For buttons or icons, describe the action they perform, e.g., “Search button” or “Play video.”
  7. Decorative Images: If an image is purely decorative, use a null alt attribute (alt=””) to let screen readers skip it.
  8. Test with Screen Readers: Check how your alt text works with screen readers to ensure it makes sense and provides value.
  9. Avoid Repetition: If the image’s content is already described nearby in the text, keep the alt text brief or null to avoid redundancy.
  10. Use Simple Language: Ensure the description is easy to understand, avoiding complex jargon or technical terms unless necessary.
