 **Open Graph (recommended)**
 - Set `og:title`, `og:description`, and `og:image` on important pages (home + detail pages) from CMS media when available.
 
+### Site-wide Schema.org JSON-LD (Organization / LocalBusiness)
+
+Business admins configure this under **Website → Settings → Structured data**. The API builds a ready `jsonLd` object for you.
+
+1. `GET /tenants/{domain}/website/business-info`
+2. If `schema.enabled` and `schema.jsonLd` is an object, render once in the root layout (or every public page):
+
+```html
+<script type="application/ld+json">
+  …paste schema.jsonLd…
+</script>
+```
+
+In Next.js App Router, put it in the root layout via `<script type="application/ld+json" dangerouslySetInnerHTML={{ __html: JSON.stringify(schema.jsonLd) }} />` when `jsonLd` is non-null.
+
+- Do **not** invent Organization fields locally when `jsonLd` is present — use the CMS object.
+- When `schema.enabled` is false, `jsonLd` is `null` — omit the script tag.
+- Tenant resolve also exposes `{ schema: { enabled, type } }` for lightweight checks; full payload is on business-info.
+- Social profile URLs from business profile are merged into `sameAs` automatically; admin can add extra https URLs.
+
+### Product + blog Schema.org JSON-LD (auto)
+
+When **Website → Settings → Structured data** is enabled, detail endpoints include a ready `schema.jsonLd` (no admin fields to edit):
+
+| Page | Endpoint | `@type` |
+|------|----------|---------|
+| Product detail | `GET /tenants/{domain}/products/by-id/{id}` (or by slug) | `Product` (+ `Offer` when store min price exists) |
+| Blog detail | `GET /tenants/{domain}/blogs/{slug}` (or by id) | `BlogPosting` |
+
+On the product/blog page:
+
+```tsx
+{product.schema?.jsonLd ? (
+  <script
+    type="application/ld+json"
+    dangerouslySetInnerHTML={{ __html: JSON.stringify(product.schema.jsonLd) }}
+  />
+) : null}
+```
+
+- Emit **in addition to** the site-wide Organization/LocalBusiness script from business-info.
+- When structured data is disabled, `schema.jsonLd` is `null` — omit the tag.
+- Do not invent Product/Article fields locally when `jsonLd` is present.
+
+### Per-page SEO meta overrides (optional)
+
+CMS forms expose optional **SEO title** / **SEO description** on products, blogs, portfolios, videos, instructions, workshops, user-products, and categories.
+
+Public detail payloads include:
+
+- `seoMetaTitle` (`string | null`)
+- `seoMetaDescription` (`string | null`)
+
+Website rules:
+
+1. Prefer `seoMetaTitle` for `<title>` when non-null; else use the normal title/`nameFa`.
+2. Prefer `seoMetaDescription` for `<meta name="description">` when non-null; else summary/abstract/about.
+3. Product/blog `schema.jsonLd` already prefers these overrides when set.
+4. Empty/null means “no override” — never show placeholder text as meta.
+
 **Checklist before shipping a page**
-1. Unique `<title>` and meta description  
+1. Unique `<title>` and meta description (use `seoMeta*` when present)  
 2. One clear H1 + sensible H2 sections  
 3. All content images have alt text  
 4. Public URL is included via CMS sitemap and/or `sitemap-config.json` static pages  
+5. Site-wide Organization/LocalBusiness JSON-LD from `business-info.schema.jsonLd` when enabled  
+6. Product/blog detail pages emit `product.schema.jsonLd` / `blog.schema.jsonLd` when present  
 
 If OpenAPI and this brief conflict, **OpenAPI wins**.

 **Open Graph (recommended)**
 - Set `og:title`, `og:description`, and `og:image` on important pages (home + detail pages) from CMS media when available.
 
+### Site-wide Schema.org JSON-LD (Organization / LocalBusiness)
+
+Business admins configure this under **Website → Settings → Structured data**. The API builds a ready `jsonLd` object for you.
+
+1. `GET /tenants/{domain}/website/business-info`
+2. If `schema.enabled` and `schema.jsonLd` is an object, render once in the root layout (or every public page):
+
+```html
+<script type="application/ld+json">
+  …paste schema.jsonLd…
+</script>
+```
+
+In Next.js App Router, put it in the root layout via `<script type="application/ld+json" dangerouslySetInnerHTML={{ __html: JSON.stringify(schema.jsonLd) }} />` when `jsonLd` is non-null.
+
+- Do **not** invent Organization fields locally when `jsonLd` is present — use the CMS object.
+- When `schema.enabled` is false, `jsonLd` is `null` — omit the script tag.
+- Tenant resolve also exposes `{ schema: { enabled, type } }` for lightweight checks; full payload is on business-info.
+- Social profile URLs from business profile are merged into `sameAs` automatically; admin can add extra https URLs.
+
+### Product + blog Schema.org JSON-LD (auto)
+
+When **Website → Settings → Structured data** is enabled, detail endpoints include a ready `schema.jsonLd` (no admin fields to edit):
+
+| Page | Endpoint | `@type` |
+|------|----------|---------|
+| Product detail | `GET /tenants/{domain}/products/by-id/{id}` (or by slug) | `Product` (+ `Offer` when store min price exists) |
+| Blog detail | `GET /tenants/{domain}/blogs/{slug}` (or by id) | `BlogPosting` |
+
+On the product/blog page:
+
+```tsx
+{product.schema?.jsonLd ? (
+  <script
+    type="application/ld+json"
+    dangerouslySetInnerHTML={{ __html: JSON.stringify(product.schema.jsonLd) }}
+  />
+) : null}
+```
+
+- Emit **in addition to** the site-wide Organization/LocalBusiness script from business-info.
+- When structured data is disabled, `schema.jsonLd` is `null` — omit the tag.
+- Do not invent Product/Article fields locally when `jsonLd` is present.
+
+### Per-page SEO meta overrides (optional)
+
+CMS forms expose optional **SEO title** / **SEO description** on products, blogs, portfolios, videos, instructions, workshops, user-products, and categories.
+
+Public detail payloads include:
+
+- `seoMetaTitle` (`string | null`)
+- `seoMetaDescription` (`string | null`)
+
+Website rules:
+
+1. Prefer `seoMetaTitle` for `<title>` when non-null; else use the normal title/`nameFa`.
+2. Prefer `seoMetaDescription` for `<meta name="description">` when non-null; else summary/abstract/about.
+3. Product/blog `schema.jsonLd` already prefers these overrides when set.
+4. Empty/null means “no override” — never show placeholder text as meta.
+
 **Checklist before shipping a page**
-1. Unique `<title>` and meta description  
+1. Unique `<title>` and meta description (use `seoMeta*` when present)  
 2. One clear H1 + sensible H2 sections  
 3. All content images have alt text  
 4. Public URL is included via CMS sitemap and/or `sitemap-config.json` static pages  
+5. Site-wide Organization/LocalBusiness JSON-LD from `business-info.schema.jsonLd` when enabled  
+6. Product/blog detail pages emit `product.schema.jsonLd` / `blog.schema.jsonLd` when present
