Alt Text Best Practices
How to write effective image descriptions
Be Specific
Describe the actual content of the image in detail but stay concise.
Keep it Concise
Most screen readers cut off alt text after about 125 characters.
Use Keywords
Include relevant keywords naturally, but avoid keyword stuffing.
Context is Key
Describe the image in relation to the surrounding content.
Ignore Decoratives
Use empty alt tags (alt="") for purely decorative elements.
Avoid Phrases
Don't use "image of" or "picture of". It's already implied.
