Learn how to write product image alt-text that improves SEO, accessibility, and conversions. With real examples for Etsy, Shopify, and Amazon listings.

What is Alt-Text and Why E-commerce Sellers Need It

Alt-text (alternative text) is a written description of an image. It serves three critical purposes: 1. Accessibility: Screen readers read alt-text to visually impaired users 2. SEO: Google uses alt-text to understand and rank images 3. Fallback: Displays when images fail to load For e-commerce, alt-text is often the difference between your product appearing in Google Image Search or not.

The Alt-Text Formula for Product Images

Use this formula for consistent, effective alt-text: [Material] + [Color/Pattern] + [Product Type] + [Key Feature] + [Size/Variant] Examples: • "Hand-knitted merino wool scarf in burgundy, 180cm length" • "Vintage brass table lamp with adjustable arm, art deco style" • "Organic cotton baby onesie, sage green with snaps, 0-3 months" Be specific, be natural, and include details that shoppers search for.

Common Alt-Text Mistakes That Hurt Rankings

Avoid these common mistakes: ❌ Empty alt-text: alt="" — Google ignores the image entirely ❌ Keyword stuffing: alt="buy cheap blue mug ceramic mug best mug" — Google penalizes this ❌ Too generic: alt="product image" — provides zero SEO value ❌ Too long: alt="This is a beautiful hand-crafted..." (200+ chars) — gets truncated ❌ Duplicate: Using the same alt-text for all images on a page Each image should have unique, descriptive, keyword-aware alt-text.

Platform-Specific Alt-Text Tips

Etsy: Alt-text comes from your file name and listing tags. Use descriptive file names. Shopify: Set alt-text in the image editor for each product photo. Shopify displays it in the HTML img tag.
