Why Image Alt Text and File Names Matter More Than You Think for Ecommerce SEO

When most store owners think about SEO, they focus on product titles, descriptions, and meta tags. But there’s a hidden layer of optimization that often gets ignored: your images.

From alt text to file names, these small details can make a big difference in how your products show up in search — and even how customers experience your site.

🖼️ Why Image SEO Matters for Ecommerce

  • Search engines can’t “see” images — they rely on alt text and file names to understand what’s in the picture.

  • Google Images is a major traffic source. Shoppers often browse images before clicking through to buy.

  • Accessibility matters. Alt text helps visually impaired users understand what’s on the page.

  • Faster page loads with optimized images improve both SEO rankings and conversion rates.

In short: optimizing images isn’t optional. It’s a missed opportunity if you’re not doing it.

📝 Alt Text: More Than Just Accessibility

Alt text (alternative text) describes what’s in an image. It’s essential for screen readers, but it’s also used by search engines to rank your products.

Example:

Instead of generic alt text like:
❌ “image123.jpg”

Use:
✅ “Black leather crossbody handbag with gold chain strap”

That one change makes your product:

  • Easier to find in search results

  • More descriptive for shoppers browsing visually

🗂️ File Names: An Overlooked SEO Boost

Search engines also look at image file names to understand what’s in the picture. Yet most stores upload files like:
❌ IMG_2025_032.jpg

When they should look more like:
✅ mens-running-shoes-navy-blue.jpg

It’s a simple fix that adds valuable SEO signals.

⚡ The Easy Way: Image Optimizer for BigCommerce

With Image Optimizer, you can:

  • ✅ Automatically generate SEO-friendly alt text for all images

🚀 Why This Matters for Your Store

Every product photo is a chance to get discovered. When images are optimized:

  • Your store ranks higher in Google Search and Google Images

  • Customers find your products faster

  • Accessibility improves, which can also support compliance

It’s one of the easiest SEO wins most BigCommerce merchants are overlooking.
