| Criterion | Lumi | Smart 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. | Automate and simplify store-wide SEO tasks, from meta tags and alt tags to structured data and broken links. |
| Catalog coverage | Product-image alt text, product descriptions, search titles, and meta descriptions. Available features vary by plan. | Covers products and collections alongside theme, file, link, and technical SEO work. |
| 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. | Mixes AI generation, bulk optimization, audits, and automation across its SEO feature set. |
| Broader scope | Focused on Shopify product-content cleanup rather than replacing a full SEO, site-speed, or general AI toolkit. | Includes image optimization, page speed, JSON-LD, broken links, backlinks, redirects, and sitemap controls. |
| Best fit | Shopify teams that want missing-alt-text detection, selected content drafts, review, publishing, and generation history in one place. | Stores that want mature, broad SEO automation with technical and content tools. |

Not in every use case. Stores that want mature, broad SEO automation with technical and content tools. Lumi is purpose-built for teams that find missing alt text, choose other fields to refresh, review drafts, publish approved updates, and keep generation history.
Smart SEO's primary job is to automate and simplify store-wide SEO tasks, from meta tags and alt tags to structured data and broken links. Lumi is organized around finding missing image alt text, choosing other product fields to refresh, reviewing drafts, publishing approved updates, and keeping generation history.
You want technical SEO and link-management features. Structured data and page speed belong in the same tool as content optimization. Broad SEO automation matters more than reviewable content generation and alt-text fix records.
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.
