Google Merchant Center
Google Merchant Center is Google’s free tool where businesses upload product information so their products can appear across Google, including Google Shopping, Shopping ads and free listings. Shopify stores usually connect to it through the Google & YouTube app.

Misrepresentation
Misrepresentation is a Google Merchant Center policy that prohibits listings or websites that leave out important information or give misleading information about products or the business. It covers six areas: unacceptable business practices, coordinated deceptive practices, dishonest pricing and transaction conditions, unavailable offers, manipulated media and unreliable claims.
Account suspension
An account suspension means Google has stopped showing all of a Merchant Center account’s products because of a policy violation. Products stay hidden until the problems are fixed and a review is approved.
Account warning
An account warning is Google’s notice that a Merchant Center account has a policy problem that must be fixed by a deadline. During the warning period products can keep showing, sometimes with limited visibility. If the problem isn’t fixed in time, the account may be suspended.
Warning period
The warning period is the time Google gives a merchant to fix a policy problem before suspending the account. For most violations, Google’s warning email gives 7 or 28 calendar days. For some misrepresentation types, Google warns at least 7 days before suspending.
Egregious violation
An egregious violation is a policy breach Google considers so serious that it suspends the account immediately, without a warning. Under the misrepresentation policy, unacceptable business practices, coordinated deceptive practices and dishonest pricing and transaction conditions are treated as egregious.
Needs attention
Needs attention is the tab in Merchant Center (under Products) that lists account and product issues. It is where merchants see what Google found, start a review request, and check when a cool-down period ends.
Request review
A review request asks Google to re-check an account or product after the merchant has fixed an issue, or believes Google made a mistake. Merchants choose “I fixed the issue” or “I disagree with the issue”. Google says reviews can take up to 7 business days.
Courtesy review
A courtesy review is the single review a merchant can request during a 7- or 28-day warning period, according to Google Merchant Center Help.
Cool-down period
A cool-down period is a waiting time during which Google disables the review button. According to Google, a one-week cool-down may begin if issues aren’t resolved by the second review attempt, it can get longer with each unsuccessful review, and Google support can’t shorten it.
Identity verification
Identity verification is Google’s check that a real, identifiable business runs a Merchant Center account. Google often requires it before a merchant can request a review of an account-level suspension, including misrepresentation suspensions.
Website needs improvement
“Website needs improvement” is a Merchant Center issue indicating Google found the store’s website incomplete, hard to use, or missing information shoppers need, such as working pages, contact details or policies. It often appears alongside misrepresentation.
Item disapproval
An item disapproval means Google won’t show one specific product, because of a data problem (such as a wrong price or missing identifier) or a policy problem. The rest of the account can keep showing.
Preemptive item disapproval
A preemptive item disapproval (PID) is a state Google can apply to products while it reviews an account. Google’s help pages say items in this state can be put forward for review once any cool-down period ends.
Free listings
Free listings are unpaid product listings that can appear on Google surfaces such as the Shopping tab. They require a Merchant Center account in good standing; a suspension removes them too.
Shopping ads
Shopping ads are paid Google Ads that show a product’s image, title, price and store name. They draw on Merchant Center product data, so a Merchant Center suspension also stops Shopping ads.
GTIN
A GTIN (Global Trade Item Number) is a product’s barcode number, such as a UPC, EAN or ISBN. Google uses GTINs to identify products. Merchants should never invent one; in Shopify the GTIN goes in each variant’s barcode field.
identifier_exists
identifier_exists is a product data attribute that tells Google whether a product has standard identifiers such as a GTIN, brand and MPN. Setting it to “no” (false) is the correct choice for products that genuinely have no barcode, such as custom or handmade items.
Product data source
A product data source (often called a feed) is how product information reaches Merchant Center. For Shopify stores it is usually synced automatically by the Google & YouTube app. Google won’t process a review request if the data source is empty.
Google & YouTube app
The Google & YouTube app is Google’s official Shopify sales channel. It connects a Shopify store to Google Merchant Center and syncs products, and merchants can start a Merchant Center re-review from its Settings tab.
