CG Score is CleverGraph's proprietary 0–100 domain trust rating. It blends 11 independent domain signals — traffic authority, domain age, archive history, malware and safe-browsing scans, SSL validity — with 7 live on-page content quality checks and 3 email-authentication records (MX, SPF, DMARC) to tell you how trustworthy a source is.
Each checkpoint is scored 0–100 and tier-weighted, then combined into a composite. Independent domain signals drive most of the score (~77%), live on-page content quality contributes ~15%, and email-authentication records (MX/SPF/DMARC) contribute ~8%. The result maps to an algorithmic grade from A+ (exceptional authority) to F (unverified).
A score of 80 or above (grade A/A+) indicates high, citable authority. 60–79 (grade B/C) is broadly dependable but worth corroborating. Below 60 (grade D/F) should be treated as directional only until independently confirmed.
Yes. CG Score is free for every CleverGraph user. Guests get three free checks per hour without signing in, and registered users get unlimited checks protected by fair-use limits.
No. CG Score rates the domain, not a specific article. A high-scoring domain has a strong track record, but you should still apply critical judgment to any individual piece of content.
