Alt Text: The Hidden SEO Goldmine for Ecommerce Sites

If you're running an ecommerce site, you're sitting on untapped SEO potential. Every product image on your site is a chance to rank higher in search results and drive more sales. The secret? Alt text.

Most online stores treat alt text as an afterthought. They either skip it completely or use generic descriptions like "product image." But smart ecommerce developers know that good alt text can boost search rankings, increase traffic, and help customers find products faster.

Why Alt Text Matters More for Ecommerce

Ecommerce sites are different from regular websites. You have hundreds or thousands of product images. Each one is a potential entry point for customers to discover your products.

Think about it: when someone searches for "black leather boots size 9," they might find your product through Google Images before they ever see your product page in regular search results.

Here's what good alt text does for your online store:

• Captures long-tail search traffic: Specific product descriptions match specific searches
• Improves product page rankings: Search engines understand your content better
• Increases image search visibility: Your products show up in Google Shopping and image results
• Helps mobile users: Alt text appears when images load slowly on mobile connections

The Ecommerce Alt Text Formula

Writing alt text for product images isn't the same as writing it for blog photos. You need to think like a customer searching for products.

Start with the Basics

Include the essential product details customers search for:

• Product type
• Brand (if relevant)
• Key features
• Color
• Size (when visible)

Example: "Nike Air Max 270 black running shoes"

Add Descriptive Details

Include visual elements that help customers understand the product:

Good: "Red cotton t-shirt with round neck and short sleeves"

Better: "Men's red cotton crew neck t-shirt with short sleeves, front view"

Include Context When Helpful

Sometimes showing how the product is used adds value:

Product shot: "Stainless steel coffee maker with glass carafe"

Lifestyle shot: "Woman using stainless steel coffee maker in modern kitchen"

Real Examples from Successful Stores

Common Ecommerce Alt Text Mistakes

Using SKU Numbers: "Product #ABC123" tells customers nothing useful.

Being Too Generic: "Product image" or "item photo" wastes an SEO opportunity.

Forgetting Multiple Images: Each product angle needs its own specific alt text.

• Main image: "Black leather jacket, front view"
• Back view: "Black leather jacket, back view showing design details"
• Detail shot: "Black leather jacket zipper and pocket detail"

Ignoring Lifestyle Images: Don't just describe the setting, connect it to the product.

Bad: "People at a party"

Good: "Friends wearing casual dresses at outdoor party"

Technical Implementation Tips

For Product Catalogs

If you're pulling product data from a database, create alt text templates:

[Brand] [Product Name] [Color] [Product Type]

This gives you: "Nike Air Force 1 white sneakers"

For Image Variants

Different product images need different alt text:

• Main product shot: Focus on the product itself
• Lifestyle images: Include context and usage
• Detail shots: Highlight specific features
• Size/fit images: Mention the model or sizing context

For Generated Content

If you're auto-generating alt text from product data, include:

• Product title
• Primary color
• Category
• Key attributes

But always review auto-generated text. Customers search in natural language, not database field names.

Advanced Alt Text Strategies

Seasonal Keywords

Update alt text for seasonal relevance:

• "Red sweater" becomes "Red Christmas sweater" in December
• "Sandals" becomes "Summer beach sandals" in warmer months

Local SEO Integration

For stores with physical locations: "Wedding dress available at [City] bridal boutique"

Voice Search Optimization

People ask voice assistants: "Show me black running shoes under $100" Your alt text: "Black running shoes under $100, Nike brand"

Google Search Console: Monitor image search impressions and clicks
