FeedShine is a Shopify product feed app that builds and maintains catalogs for Google Shopping, Meta, Microsoft Bing, Pinterest, TikTok, Snapchat, Criteo and AppLovin. It pulls product data straight from Shopify, so a working feed takes about a minute with no manual mapping. All 72 mappable Google attributes are editable, including fields Shopify does not expose on its own, and AI can rewrite titles and descriptions for search intent. Feeds push to Google Merchant Center through the Merchant API and flag the attribute errors that cause disapprovals before you submit, rather than after Google rejects the product. Shopify Markets is supported, so each country gets its own feed with local pricing, translated content and the correct URLs. Merchants can override any single product or apply bulk changes across the catalog. Output formats include XML, TSV and CSV as well as direct API push. Paid plans refresh in near real time and free plans run on a schedule.
