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 Use this only if you genuinely can't use scheduled fetch, since manual feeds drift out of date the moment prices or stock change.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.

Frequently Asked Questions: Integrating BigCommerce with Google Shopping
What do I need before integrating my BigCommerce store with Google Shopping?
Before starting the integration, you will need an active BigCommerce store, a Google Merchant Center account, and a Google Ads account. You should also ensure your store meets Google's product data requirements and that your website is verified and claimed within Google Merchant Center.
How do I connect my BigCommerce store to Google Merchant Center?
You can connect your BigCommerce store to Google Merchant Center by using the built-in Google Shopping app available in the BigCommerce App Marketplace. Once installed, the app guides you through authorizing your Google account, mapping your product feed, and submitting your catalog for review.
Why are my products disapproved in Google Merchant Center?
Products are commonly disapproved due to missing or incorrect data in your product feed. Common causes include:
- Missing GTINs, MPNs, or brand information
- Incorrect or mismatched pricing between your store and the feed
- Images that do not meet Google's quality requirements
- Prohibited or restricted product categories
- Shipping and tax settings that are incomplete or misconfigured
How long does it take for products to appear in Google Shopping after submission?
After submitting your product feed, Google typically takes between 3 to 5 business days to review and approve your products. In some cases, particularly for new Merchant Center accounts, the review process may take up to 7 business days.
Do I need to manually update my product feed in Google Merchant Center?
No. When using the BigCommerce and Google Shopping integration, your product feed can be set to update automatically. You can configure scheduled fetch intervals within Google Merchant Center so that any changes to pricing, inventory, or product details in your BigCommerce store are reflected in your feed without manual intervention.
Can I advertise specific products rather than my entire catalog on Google Shopping?
Yes. Within Google Ads, you can create product groups inside your Shopping campaign to target specific items based on attributes such as brand, category, product type, or custom labels. This allows you to set individual bids and control which products receive advertising spend.
Frequently Asked Questions: Integrating BigCommerce with Google Shopping
What is Google Shopping and why should I integrate it with my BigCommerce store?
Google Shopping is a product discovery and comparison platform powered by Google that displays your products directly in Google Search results. Integrating your BigCommerce store with Google Shopping allows you to reach millions of potential customers who are actively searching for products like yours, increasing visibility, driving qualified traffic, and boosting sales without relying solely on organic search rankings.
What do I need before I can connect BigCommerce to Google Shopping?
Before starting the integration, you will need the following:
- An active BigCommerce store with products listed
- A Google account with access to Google Merchant Center
- A verified and claimed website URL in Google Merchant Center
- A Google Ads account linked to your Merchant Center account
- Products that comply with Google Shopping policies
How do I create and submit a product feed from BigCommerce to Google Merchant Center?
BigCommerce allows you to generate a Google Shopping product feed directly from your store. You can use the built-in Google Shopping app or a third-party feed tool to export your product data in a format Google Merchant Center accepts. Once your feed file is created, you submit it in Merchant Center under the Products section by creating a new feed, specifying your country and language, and uploading or scheduling the feed URL for automatic updates.
How long does it take for my products to appear in Google Shopping after submission?
After submitting your product feed to Google Merchant Center, it typically takes between 24 and 72 hours for Google to review and process your products. In some cases, especially for new accounts, the review period can extend up to a few business days. You can monitor the status of your products in the Merchant Center dashboard under the Diagnostics tab.
What are common feed errors in Google Merchant Center and how do I fix them?
Some of the most frequently encountered feed errors include:
- Missing required attributes — Ensure every product includes a unique ID, title, description, link, image link, price, and availability
- Invalid GTIN or MPN — Verify that your product identifiers match official manufacturer data
- Mismatched prices — The price in your feed must exactly match the price displayed on your product page
- Disapproved images — Use high-quality images with a plain white or light background and no watermarks
- Policy violations — Review Google Shopping policies to ensure your products and landing pages comply
Do I need Google Ads to use Google Shopping with BigCommerce?
To run paid Shopping ads, yes, you need a Google Ads account linked to your Merchant Center. However, your products can also appear in free product listings on the Google Shopping tab without an active ad campaign. Setting up Google Ads Shopping campaigns gives you greater control over bidding, targeting, and placement to maximise your return on investment.
How often should I update my BigCommerce product feed for Google Shopping?
Google recommends updating your product feed at least every 30 days to keep your listings active. However, for stores with frequently changing inventory, pricing, or promotions, it is best practice to update your feed daily or in near real time. Most BigCommerce feed integrations support scheduled automatic updates to keep your Merchant Center data accurate and up to date.
