Even when using AI to generate alt text, it's helpful to understand what makes good alt text — especially if you're reviewing or editing it later. Well-written alt text improves accessibility, enhances SEO, and creates a better experience for all users.
Here are some simple guidelines to help you write or refine alt text effectively.
Be descriptive, but concise
Alt text should clearly describe what’s in the image — but no need to go overboard.
✅ Good: A woman holding a reusable coffee cup in a park
🚫 Too much: A young brunette woman in a beige coat holding a reusable cup made of bamboo while walking in a sunny park in autumn
Avoid "image of" or "photo of"
Screen readers already know it’s an image — no need to say it.
✅ Good: Golden retriever puppy playing with a tennis ball
🚫 Bad: Image of a golden retriever puppy
Include relevant context
If the image supports a marketing message or a product, reflect that.
✅ Example for e-commerce: Red leather crossbody bag on a wooden table, front view
✅ Example for content blog: Woman laughing during a morning run, symbolizing motivation
Use keywords (when relevant)
You can include keywords naturally for SEO, but don’t stuff them.
✅ SEO-friendly: Organic cotton white T-shirt folded neatly on a shelf
🚫 Keyword-stuffed: White T-shirt organic cotton sustainable eco-friendly clothes
Use plain language
Keep it simple, clear, and direct.
✅ Good: Freshly baked sourdough bread on a cutting board
🚫 Bad: A scrumptious loaf imbued with rustic charm resting upon a wooden slab
