Alt Text Best Practices

Follow these guidelines for accessible, SEO-friendly image descriptions.

Do This

  • Be specific and descriptive

    "Golden retriever puppy playing with red ball in sunny backyard"

  • Keep it concise (125 characters or less)

    Screen readers may cut off longer descriptions

  • Describe the image content, not its purpose

    Focus on what's in the image, not why it's there

  • Include relevant keywords naturally

    Helps with image SEO when done appropriately

Don't Do This

  • Don't start with "Image of" or "Picture of"

    Screen readers already announce it's an image

  • Don't use the filename

    "IMG_2847.jpg" tells users nothing

  • Don't keyword stuff

    "Dog puppy pet animal canine golden retriever dog"

  • Don't leave it empty (for meaningful images)

    Empty alt text should only be used for decorative images
