Google's own malware and social-engineering threat list, the same one Chrome checks.

FAQ
What does Google Safe Browsing check for?
It's the same malware and social-engineering (phishing) threat list Chrome, Firefox, and Safari use to show their own "dangerous site" warnings, queried directly for this domain and its URL.
Why does SEOTechTests use Google Safe Browsing?
It's the list that actually drives browser warnings for most users, so a match here reflects a threat classification with direct, immediate real-world consequences for visitors.
What does a FAIL from this check mean?
A confirmed match against Google's malware or social-engineering list -- treated as a critical, high-confidence finding that alone can cap the overall Domain Security Score.
Does a clean result guarantee the site isn't a threat?
No. Google's list reflects sites it has already classified; a newly compromised or newly created malicious page may not be listed yet.
