The ideal length is between 80–140 characters. This keeps descriptions specific and readable without being spammy.
Do I need alt text for decorative images?
If an image is purely decorative and adds no meaning, you can leave alt text empty. However, product photos, blog images, and infographics should always include descriptive alt text.
