How to Extract Vendor and Supplier Data from Shopify DOM

When auditing competitor Shopify stores, some of the most valuable details are hidden from the standard frontend interface. Many store owners hide the manufacturer brand or supplier name on their product pages. However, you can often extract vendor data from the Shopify DOM because the platform still sends this metadata to the browser page source.

Here is how to read and extract these hidden vendor attributes safely.

1. Understanding the JSON-LD Script Tags

Shopify storefronts insert metadata structures (like Schema.org schemas) into their pages for search engine indexing. By viewing the page source or DOM, you can look for tags containing `"vendor"` or `"brand"`. These often contain the name of the original manufacturer or private agent.

2. Automating the Process

Instead of manually inspecting the page source code for every item, you can use browser extensions. Extensions like Shopify Product Exporter parse the JSON structures in the DOM automatically, outputting clean columns for `Vendor`, `Brand`, and `SKU` directly into your spreadsheet exports.
