- Keep alt text concise (under 125 characters).
- Use empty alt attributes (
alt="") for purely decorative background images.
Avoid
- Avoid starting alt text with "picture of" or "image of".
- Do not stuff repetitive keywords into alt tags.
- Avoid using image filename (e.g.
IMG_001.jpg) as alt text. - Don't leave important informational product images without alt text.
Frequently Asked Questions (FAQ)
