Browse all 58 content categories used to classify 120 million domains in our web filtering database. Understand what each category means and how domains are assigned.
Each card above is a column in that file, and one domain can hold several of them, ranked. Firewall, DNS and parental control teams run it inside their own products, offline when they need to.
Our 58-category taxonomy has been designed by web filtering experts and refined over a decade of domain classification. Each category is precisely defined to minimize overlap while covering the full spectrum of web content.
Domains can belong to multiple categories simultaneously. For example, a technology news site would be classified under both "Technology" and "News & Media" to accurately reflect its content.
Understanding how we assign categories and maintain accuracy across 120 million domains.
Machine learning models perform initial classification, while human analysts review edge cases and ambiguous domains to ensure accuracy.
Domains are periodically re-scanned and re-classified to detect content changes, compromised sites, and evolving web properties.
If you believe a domain is incorrectly categorized, submit a recategorization request. Our team reviews and responds within 24 hours.
