Account setup, feed diagnostics, website verification, linking to Google Ads, and the account suspension reasons that catch advertisers completely off guard.
Merchant Center is one of those platforms that most ecommerce advertisers set up once and then mostly ignore — until something breaks. I've had clients come to me with Shopping campaigns suddenly serving zero impressions, only to find their Merchant Center account had been suspended for weeks due to a policy violation they never noticed. The exam tests Merchant Center thoroughly because it's the operational backbone of every Shopping campaign. Understanding how it works — and what can go wrong — is essential both for passing the certification and managing real accounts.
Correct answer: B. Send a link request from Merchant Center to the Google Ads account, and then approve that request from within Google Ads
Linking requires action on both sides — you initiate the request in Merchant Center under "Linked accounts," and then approve it in Google Ads under Tools & Settings. Without this active link, Shopping campaigns in Google Ads have no product data to draw from and cannot serve. It's one of the first things I verify when taking over a Shopping account — a broken or missing link is a surprisingly common reason campaigns suddenly stop serving, especially after an account restructure or platform migration.
Correct answer: B. A process that confirms the advertiser owns or has authorised access to the website where products are sold, required before any products can be approved and Shopping ads served
Website verification and claiming are two separate steps — verification confirms you have access to the site (via Google Analytics, Google Tag Manager, HTML tag, or DNS record), and claiming associates that verified site exclusively with your Merchant Center account. Both are required before products can serve. I always complete these steps first when onboarding a new Shopping client, and double-check they're done correctly before spending any time on feed optimisation.
Correct answer: B. A summary of product disapprovals, feed errors, account-level warnings, and the specific reasons products are ineligible to serve — allowing advertisers to identify and fix issues affecting campaign reach
The Diagnostics tab is my first stop every time I audit a Shopping account. It shows you exactly how many products are approved, disapproved, or pending review — and for disapproved products, exactly which policy or data quality issue caused the problem. I've seen accounts where 40% of the product catalogue was disapproved due to fixable feed issues, silently limiting the campaign's reach for months. Reviewing Diagnostics weekly is the operational equivalent of checking the Search Terms report — non-negotiable.
Correct answer: B. Misrepresentation of self or products, policy violations (such as prohibited products), inaccurate pricing or availability, or a poor landing page experience that doesn't match the ad
Merchant Center suspensions are serious — they take all Shopping and free listing activity offline immediately. The most common causes I see are: prices in the feed not matching the website, products that violate Shopping policies (counterfeit goods, certain health products, weapons), misleading shipping or return claims, and landing pages that don't reflect what the ad promises. Reinstatement requires fixing the underlying issues and submitting a review request — which can take days to weeks. Prevention is vastly easier than recovery.
Correct answer: B. A product disapproval affects only the specific product that violates a policy, leaving other products eligible to serve; an account suspension takes the entire Merchant Center account offline, preventing all products from serving
This distinction matters enormously in practice. Individual product disapprovals are common and manageable — fix the specific issue (wrong price, missing GTIN, policy violation) and resubmit the product for review. An account suspension is a much more severe event — the entire account stops serving, including all products that were previously approved. I explain this to clients as the difference between a single product being pulled from a shelf versus the entire store being closed. Both need fixing, but the urgency and impact are very different.
Merchant Center showing warnings you've never looked at, or Shopping campaigns suddenly serving zero impressions? These are signs of feed or account issues that need urgent attention — let me diagnose what's happening.
