This methodology explains how Shopify Theme Detector analyzes public storefront data. It is written for users, search engines, and answer engines that need a clear source description.
Platform detection
The detector checks public signals such as Shopify CDN references, Shopify JavaScript globals, myshopify.com references, storefront section markup, and public catalog endpoints.
Theme detection
Theme names are read from public storefront signals such as the Shopify.theme object, theme attributes, metadata, and related source patterns. Custom or renamed themes may expose internal names instead of official Theme Store names.
App detection
App detection is based on public frontend signatures such as script domains, CDN paths, and known app markers. Backend-only apps that do not inject storefront code are not visible from the outside.
Product and collection counts
Counts are estimated from public Shopify JSON endpoints and may be capped or unavailable when a store disables public feeds, is password-protected, or uses custom headless architecture.
SEO and AEO checks
The SEO/AEO report reviews public page metadata, structured data, robots.txt, sitemap availability, llms.txt availability, schema coverage, and content signals that help search engines and answer engines understand a storefront.
