Image SEO & alt text

How to Improve Image SEO and Alt Text on Your Website

Images support trust and sales, but search engines and screen readers only understand them if you describe them clearly.

Short answer: Improve image SEO by adding unique, descriptive alt text to meaningful images, using readable file names, compressing large files, and fixing missing alt attributes on product, service, and hero images. Avoid keyword stuffing and duplicate alt text across many pages.

Alt text

What good alt text looks like

Alt text describes the image for people using screen readers and helps search systems understand image context. Describe what is in the image and why it matters on that page.

Decorative images can use empty alt (alt="") so assistive tech skips them.

Problems

Missing, generic, and duplicate alt text

  • Missing alt text — common on galleries and Shopify imports
  • Generic alt text — “photo”, “banner”, or filename only
  • Duplicate alt text — same description on every product image

An SEO audit lists URLs with image SEO gaps so you can fix catalogs systematically.

Filenames & performance

File names, lazy loading, and page speed

Use readable file names before upload (blue-running-shoes-side-view.jpg not IMG_9832.jpg). Compress large hero and product images so pages stay fast on mobile.

Lazy loading is fine for below-the-fold images; keep critical hero images optimized and quickly loadable.

Products & services

Product and service page images

On ecommerce product pages, describe the product variant shown — color, size, material, or use case. On service pages, describe the work, team, or location shown rather than repeating your company name in every alt tag.

Shopify and Wix owners often fix alt text in bulk with SEO apps — see Shopify SEO and Wix SEO guides.
