A complete guide to setting up a Google Shopping product feed in 2026, covering the shared Merchant Center foundation and the specific integration steps for Shopify, Wix, and Squarespace.
A Google Shopping feed is the structured product data that powers Shopping ads, free product listings, and increasingly Google's AI-driven agentic shopping, where an AI assistant surfaces and can act on a product directly. The feed itself lives inside Google Merchant Center, and how you get your catalog there cleanly depends on your platform. This guide covers the shared setup logic and the specific path for Shopify, Wix, and Squarespace.
Merchant Center reads a structured feed, one row per product, each with a defined set of attributes: title, description, price, availability, condition, and a product identifier among others. Google uses this feed to decide what to show, to whom, and across which surfaces, standard Shopping ads, free listings that appear without any ad spend, and now AI shopping experiences that read the same underlying attribute data. A clean, complete feed determines whether your products show up across all of these surfaces or are effectively invisible in places you don't realize exist.
Go to Merchant Center and sign in with a Google account, ideally the same business account used for your other Google tools covered earlier in this series. Provide your business information, including a verified business address and website URL. You'll need to verify and claim your website URL inside Merchant Center, typically through one of the same verification methods used for Search Console, an HTML tag, a file upload, or a Google Analytics connection.
Install the Google & YouTube app from the Shopify App Store. Connect your Google account and your Merchant Center account inside the app, creating a new Merchant Center account through the flow if you don't already have one. Once connected, Shopify syncs your product catalog into Merchant Center automatically and keeps it updated as your catalog changes, no manual feed file required.
Wix has a native integration for this under its Marketing & SEO section. Connect your Google account, then follow the prompts to link or create a Merchant Center account. Wix handles the ongoing feed sync automatically once connected, similar to the Shopify flow.
Squarespace's Google Shopping integration lives under the Google panel inside your dashboard, listed as Merchant Center. A few eligibility requirements apply specifically to this integration: your store needs to sell physical products, have a shipping option configured, be located in the United States with the site language set to English, and your plan needs to be Core, Plus, Advanced, or one of the Commerce tiers. Multi-client and sub-accounts in Merchant Center aren't currently supported through this integration. Once connected, Squarespace automatically syncs physical products to Google Product Listings.
Once your feed is syncing, go to the Diagnostics section inside Merchant Center and review any flagged issues before your products go live across Shopping surfaces. Common problems include missing GTINs (Global Trade Item Numbers) for branded products, image quality that doesn't meet Google's minimum resolution requirements, and titles that are either too generic or stuffed with keywords in a way that reads as spam rather than a genuine product name.
If you plan to run Shopping ads, not just free listings, link your Merchant Center account to Google Ads. Inside Merchant Center, go to Settings, then Linked Accounts, and connect your Google Ads account using the same login or granting access if they're separate. This link is what makes your product catalog available as a source for Shopping campaigns inside Google Ads.
A feed that syncs correctly on day one can develop problems over time as your catalog changes, a new product added without a required attribute, an image that stops loading, a price mismatch between your feed and your actual website. Check the Diagnostics section periodically, not just at initial setup, since Google actively penalizes feeds with data that doesn't match what a shopper actually sees on the destination page.
Merchant Center itself and free product listings cost nothing. You only pay when running actual Shopping ads through Google Ads, at which point standard PPC costs apply based on your bidding and competition for relevant search terms.
Once your feed syncs successfully and passes Google's review, free listings typically appear within a few days. If you're also running paid Shopping ads, those can begin serving once the campaign is live and approved, generally within 24 hours of campaign launch assuming no data quality issues are flagging your products.
Not directly as a single shared feed, since Google Merchant Center and Meta Commerce Manager are separate systems, but most ecommerce platforms, including Shopify, Wix, and Squarespace, can sync the same underlying product catalog to both simultaneously through their respective native integrations, so you maintain one source of truth even though the two feeds technically live in different places.
With Google Shopping and Instagram Shopping both connected to your product catalog, and your tracking stack confirmed accurate through Google Analytics 4 and verified tracking, your core setup is complete. If you'd rather have your full commerce and analytics stack set up, verified, and actively managed by someone who does this daily, that's exactly what our paid media team helps with as part of a free Growth Gap Analysis.
