Where to find it: Shopify Admin → Apps → Firefly Sky SEO → Image Alt Optimizer.
Recommended workflow
- Under Step 1: Scan images, scan all images or choose products, collections, blogs, or the file library.
- Optionally choose Scan frontend references to identify whether a file is currently used on the storefront.
- Under Step 2, choose the output language, scope, image type, and reference status.
- For the safest first run, select Images missing Alt only.
- Choose Batch optimize, then review results in the table.
- Use Edit for a manual correction or Revert to restore the original Alt text.
Filters and statuses
Use Products, Collections, Blogs, File library, or All tabs. You can also filter by format, search by filename or resource, sort by update time or optimization state, and separate active from draft resources.
SVG files: automatic vision optimization skips SVG because SVG is XML rather than raster pixel data. Use Edit to add Alt text manually.
Writing useful Alt text
- Describe the image’s purpose and visible subject concisely.
- Include a product name or relevant detail only when it helps understanding.
- Avoid “image of,” keyword stuffing, file names, and promotional claims.
- Decorative images may use empty Alt text when appropriate.
Recovery and history
Use View optimization history to audit prior changes. Revert all optimized restores optimized records in bulk; review scope carefully before using it.
