Plug in SEO is built to diagnose SEO problems and teach DIY merchants how to resolve them. Lumi connects supported findings and selected-product generation to review, publishing, and history.
Quick answer
Lumi focuses on product fields: it creates selected drafts, keeps them available for review, publishes approved changes, and tracks drafts and publications.

| Criterion | Lumi | Plug in SEO |
|---|---|---|
| Primary job | Find missing image alt text, empty descriptions, and missing SEO fields, create drafts, review them, publish approved updates, and keep generation history. | Help DIY store owners diagnose SEO problems and understand how to fix them. |
| Catalog coverage | Product-image alt text, product descriptions, search titles, and meta descriptions. Available features vary by plan. | Reviews store-wide SEO concerns rather than focusing only on product content fields. |
| Review model | Merchant-started batches always create drafts for review. Maintain can automate drafts for new-product content and missing image alt text after product updates; enabled automation can publish automatically after you opt in. | Pairs diagnostics and reporting with guidance for merchants who want to control their SEO work. |
| Broader scope | Focused on Shopify product-content cleanup rather than replacing a full SEO, site-speed, or general AI toolkit. | Oriented around SEO education, issue diagnosis, and ongoing reporting. |
| Best fit | Shopify teams that want missing-alt-text detection, selected content drafts, review, publishing, and generation history in one place. | Hands-on merchants who want to learn SEO and work through store-wide recommendations. |

Not in every use case. Hands-on merchants who want to learn SEO and work through store-wide recommendations. Lumi focuses on product fields: it creates selected drafts, keeps them available for review, publishes approved changes, and tracks drafts and publications.
Plug in SEO's primary job is to help DIY store owners diagnose SEO problems and understand how to fix them. Lumi is organized around finding missing image alt text, choosing other product fields to refresh, reviewing drafts, publishing approved updates, and keeping generation history.
Your main need is SEO diagnosis and education. You prefer to work through recommendations yourself. Store-wide SEO guidance matters more than AI-assisted catalog publishing.
No. Lumi helps with product-image alt text and search-content cleanup, but accessibility involves the full storefront and search results depend on many factors.
