GMC Compliance Score: What It Is and Why It Matters
A compliance score is a single number that tells you how close your store is to a Google Merchant Center suspension. Here is how it works, how to interpret it, and how to use it.
A GMC compliance score is a single 0-100 number that summarizes how well your store meets Google Merchant Center's policy and feed requirements. It is not an official Google metric. It is a framework that combines the dozens of individual policy checks Google runs into one number you can track over time, alert on, and report to clients. Without a score, GMC health is invisible: you do not know if things are improving or deteriorating until something breaks.
What a compliance score actually measures
The score is calculated against five categories of checks:
- Feed quality: required attributes present, GTINs valid, brand populated, images reachable
- Structured data: Product schema valid on landing pages, matching feed values
- Policy compliance: business identity consistent, policy pages customized, no misrepresentation triggers
- Page quality: mobile speed, returns declarations, contact info accessible
- Sales experience: shipping accurate, returns clear, no fake urgency or scarcity
How it's calculated
Start at 100. Deduct for active issues, weighted by severity:
| Issue type | Deduction | Cap |
|---|---|---|
| Critical (suspension-level) | -30 each | No cap |
| Error | -5 each | -40 max |
| Warning | -2 each | -20 max |
Bonus points are added for clean audits: complete structured data, all policy pages present, no image violations. The bonus offsets minor warnings but cannot raise a score that has critical issues.
Score ranges and what each means
| Range | Rating | Meaning |
|---|---|---|
| 90-100 | Excellent | Minimal risk. Maintenance mode. |
| 70-89 | Good | Minor issues. Address within 2 weeks. |
| 50-69 | Concerning | Multiple issues affecting performance. Act now. |
| Below 50 | High risk | Suspension likely if not addressed immediately. |
How to use the score in agency client reporting
Score-based reporting wins client retention. The pattern:
- Onboard a client. Record their score on day 1.
- Run audits weekly. Watch the score climb as you fix issues.
- Include the score and trend in every monthly client report.
- When the score plateaus, focus on the highest-impact remaining issue.
- When a client renews, lead with the score: "We took your store from 45 to 89."
Concrete numbers beat vague reports. Clients who see month-over-month improvement renew. Clients who get "we did some work this month" reports churn.
Score signals you should react to immediately
- Score drops 10+ points week-over-week. Something material changed. Find it.
- Score crosses below 70 from above. You moved into the concerning band; do not wait for it to recover.
- Score below 50. Suspension becomes likely if this isn't addressed soon. Treat as urgent.
- New critical issue appears. Any -30 critical deduction is a single SKU-level signal but indicates a policy violation worth investigating site-wide.

Run free auditBottom line
A compliance score is a single number that makes GMC health visible. Track the trend, alert on drops, use the score for client reporting, and treat any score below 50 as urgent. Most successful merchants and agencies treat the score the way they treat Core Web Vitals: a leading indicator they watch every week.
Frequently asked questions
Is a compliance score an official Google metric?
No. It is a framework that combines Google's policy and feed checks into a single tracked number. Google does not publish a compliance score itself, but every audit tool that scores stores agrees on the same underlying signals.
Can two stores have the same score but different risks?
Yes. Two stores can hit 75 with very different risk profiles: one has many small warnings, another has one critical misrepresentation flag. Use the score as a starting point, then look at the breakdown by severity.
What is a good baseline score for a healthy store?
85+. Stores at 85+ rarely face account-level issues. Stores 70-85 carry minor risk that can escalate if not addressed. Stores below 70 should be treated as urgent.
Does the score change in real time?
Most tools recompute weekly. FeedShield recomputes whenever a new audit runs (typically weekly, more often during promo cycles). Real-time scoring is overkill for compliance and adds noise.
Should I share the score with my Google Ads rep?
Yes, especially if you have a recurring rep relationship. Reps respond better to merchants who can quantify their compliance posture than to merchants who say 'we have some issues we are working on.'
How do agencies use compliance scores with clients?
Show clients their score before and after onboarding. A client who went from 45 to 89 under your management has a concrete reason to renew. No vague reports; just the number going up.
