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 is likely within 30 days. 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.
