The **homepage** (`/`) includes a visible FAQ section and JSON-LD `WebPage` + `FAQPage` + `Organization` / `WebSite` / `SoftwareApplication` in a single `@graph` for search and AI answers.

**Blog article** (`/eng/blog/what-shopify-apps-does-skims-use`) emits `Article` (with `inLanguage: en-US`, `isAccessibleForFree`, publisher/author URLs), `FAQPage` when FAQs exist, `BreadcrumbList`, and `Organization` (`sameAs` social profiles) in addition to standard Open Graph and Twitter Card tags (`og:image:alt`, `twitter:site`, etc.).

## Core Functionality

### Shopify Detection Tool

- [Homepage - Shopify Detector](https://apps.nivk.com/): Main detection interface
  - Instant Shopify store detection (under 3 seconds)
  - Theme identification (Dawn, Debut, Brooklyn, custom themes)
  - App detection (Judge.me, Klaviyo, Google Analytics, etc.)
  - Technical stack analysis
  - Confidence scoring based on multiple signals
  - Rate limiting: 10 requests per minute per IP

**Detection Methods**:
- HTTP headers analysis (X-Shopify-Stage, X-Shopify-Shop-Id, X-Shopify-Request-Id)
- Page source analysis (cdn.shopify.com, Shopify.theme, Shopify.shop objects)
- URL pattern matching (/collections/, /products/, /cart, /checkout)
- JavaScript object analysis (Shopify-specific objects and functions)

- Network request analysis

**Accuracy**: 95%+ for standard Shopify stores. Lower accuracy for headless Shopify setups or stores that hide Shopify signals.
