How AdNabu Syncs Shopify with Google Merchant Center

AdNabu is a Shopify product feed management app that connects your Shopify catalog to Google Merchant Center (GMC) and other shopping channels. It syncs product data instantly, supports import/export of your full catalog, and lets you automate feed actions through Shopify Flow. This applies if you run a Shopify or Shopify Plus store and want your products to appear on Google Shopping, Google Ads, and marketplaces without manually rebuilding feeds.

What "Sync" Means in AdNabu

Syncing here means AdNabu pulls product data from your Shopify store and pushes it to your connected channels as a feed. The core sync behaviors described on the site are:

• Instant Shopify Sync — product data syncs from Shopify to your Google Shopping feed immediately rather than on a slow batch cycle.
• Instant Shopify Product Updates to GMC — when product data changes in Shopify, the update flows to Google Merchant Center.
• Import & Export Product Feed — you can import or export your entire product catalog, useful for bulk changes or migrations.

The practical effect: you edit a product in Shopify, and the feed reflects it without a manual re-upload.

What Data Can Be Synced and Adjusted

AdNabu doesn't just mirror raw Shopify fields — it lets you transform them before they reach the channel. Supported adjustments include:

So the sync is configurable: you decide which products go out, in what currency and language, and with which attributes.

Handling Errors and Edge Cases During Sync

Feed syncs commonly break on missing or invalid product data. AdNabu addresses several of these directly:

• GTIN Fix — resolves GTIN-related errors on your product feed.
• Custom products support — promotes products that don't have GTIN identifiers.
• Product score — gives qualitative and quantitative suggestions on individual products, so you can spot weak listings before they cause disapprovals.
• Error-free GMC & marketplace management — the stated goal of the error-handling features.

If your catalog includes handmade, vintage, or custom items without standard identifiers, the custom products support is the relevant path.

Automation and Store Type Support

Two integration points extend the sync beyond a one-way push:

• Shopify Flow integration — connect Shopify Flow to trigger automated actions based on feed or product events.
• Shopify Headless store support — product listings work for headless commerce setups, not just standard Shopify themes.

This matters if you run a headless storefront or want feed actions tied to other store events.

Channels Beyond Google

While the sync to Google Merchant Center is central, AdNabu also manages feeds for other channels, including Facebook, Instagram, TikTok, Bing Shopping, Snapchat, Pinterest, and X (Twitter). The same Shopify data source feeds all of them, so a single product edit can propagate across channels.

Getting Started

AdNabu offers a 14-day free trial for the main Shopify app. Related apps (Google Shopping Feed, Facebook Product Feed, Meta & Facebook Pixels, Google Ads Pixel, Image Compressor & SEO, URL Redirects) list their own trial terms — some show "Free Now," others 7-day trials. Check the pricing page for current terms before installing, since trial length and plan limits are set per app.

To sync: install the app, connect your Google Merchant Center account, and let the instant sync push your catalog. Then use feed rules, blocklists, and bulk edit to clean up what goes out.
