Welcome to the second half of our two-part how-to guide for integrating your BigCommerce store with Google Shopping. In earlier guidance on product data we covered why clean product information matters; in Part 1 of this series we mapped categories and enabled products. Here in Part 2 we set up the data feed and submit your products to Google — and, just as importantly, cover the feed-quality practices that determine whether your products actually show and convert once submitted.
Create the Data Feed in Google Merchant Center
Feeds are created in your Google Merchant Center account. In the left-hand menu, open the feeds/data-feed section and add a new feed. You'll be asked for the target country and language (these must match where you actually sell and ship), the destination (Shopping ads / free listings), and a name for the feed. Set these to reflect your real selling markets — a mismatch here is a common reason products get disapproved.
Choose Your Upload Method
You'll select how the feed reaches Google:
Automatic (scheduled fetch): Google downloads your store's feed file on a schedule with no further action from you. This is the recommended option for almost every store, because product data — price and especially availability — changes constantly, and a stale feed causes disapprovals and wasted spend on out-of-stock items. In Merchant Center, give the file a name ending in .xml, then set the fetch frequency and the fetch time and time zone to a window that reflects how often your catalog changes (daily is a sensible default; more often for fast-moving inventory).
Regular uploads by merchant (manual): You download the feed from BigCommerce and upload it to Merchant Center yourself each time. Use this only if you genuinely can't use scheduled fetch, since manual feeds drift out of date the moment prices or stock change.
Connect BigCommerce to Merchant Center
For the automatic method: in Merchant Center, set the filename (ending in .xml) and configure the fetch schedule. Then log into your BigCommerce control panel and go to Marketing > Google Shopping Feed. Choose the country your store sells in from the dropdown; a window will present your feed file URL. Copy that URL, return to Merchant Center, paste it into the Feed URL field, and save. Google will now pull the feed on the schedule you set.
For the manual method: in Merchant Center set the .xml filename, then in BigCommerce go to Marketing > Google Shopping Feed, select your country, choose Export my products to a Google feed file, then Download my Google Shopping Feed file, and save it locally. Back in Merchant Center, choose to manually upload a file, select the file you just downloaded, and save. Repeat whenever your catalog changes materially.
Make the Feed Actually Perform
Submitting a feed is the start, not the finish. The data quality inside it decides whether products are approved, shown, and clicked:
- Titles are the single biggest lever. Front-load what shoppers search — brand, product, key attributes (size, color, model) — because Google matches queries heavily against the title.
- GTIN / brand / MPN: supply valid identifiers wherever they exist. Missing or wrong identifiers are a frequent cause of limited or disapproved listings.
- Price and availability must match the landing page exactly. Any mismatch between feed and live page triggers disapprovals and erodes trust — another argument for scheduled fetch.
- Images: use a clean, high-resolution main image without promotional overlays or watermarks, which violate Google's image requirements.
- Product type and Google product category: set these accurately so your items compete in the right auctions.
Verify, Then Monitor
After the first successful fetch, check the Merchant Center diagnostics for disapprovals and warnings and fix them before scaling spend — disapproved products simply don't show. Then make feed health a recurring habit: review diagnostics on a schedule, watch for items dropping to "out of stock" or "price mismatch," and treat the feed as living infrastructure, not a one-time setup. A well-maintained feed quietly outperforms a neglected one with the same budget.
Frequently Asked Questions
Automatic or manual feed? Automatic scheduled fetch for nearly everyone — it keeps price and availability current, which is the most common source of disapprovals.
Why are my products disapproved? Most often: feed/landing-page price or availability mismatch, missing GTIN/identifier, or image policy violations. Merchant Center diagnostics name the exact reason.
How often should the feed update? At least daily; more frequently for stores whose prices or stock change throughout the day.
Common Setup Mistakes to Avoid
The errors that most often stall a new BigCommerce-to-Google-Shopping integration: choosing manual uploads and then forgetting to refresh them, so the feed silently goes stale and products get disapproved for price/availability mismatch; setting the feed country or currency to something other than where you actually sell and ship; leaving GTINs and brand blank on products that have them, which limits or blocks listings; using marketing-overlaid or watermarked main images that violate Google's image policy; and treating "feed submitted" as "done" without ever opening the diagnostics tab. Every one of these is visible and named in Merchant Center's diagnostics — the mistake is not looking.
Connect the Feed to a Strategy, Not Just an Account
Submitting a clean feed makes products eligible to show; it doesn't decide how well they perform. Once the integration is healthy, the feed becomes the foundation for everything downstream: Performance Max and Shopping campaign structure, bidding, and which products you actually want to push spend behind. The feed-quality work in this guide is what makes that downstream investment efficient — strong titles, correct identifiers, and accurate price/availability lower disapprovals and improve match quality, so the same budget reaches more of the right shoppers. A neglected feed caps the ceiling of even a well-managed campaign; a well-maintained one quietly raises it.
