How Our Category Taxonomy Works

Our 59-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.

  • Categories aligned with IAB Content Taxonomy standards
  • Multi-label classification supports overlapping content types
  • Confidence scoring for each category assignment
  • Hierarchical parent-child relationships between categories
  • Continuous refinement based on analyst review and feedback

Category Classification Details

Understanding how we assign categories and maintain accuracy across 100 million domains.

AI + Human Review

Machine learning models perform initial classification, while human analysts review edge cases and ambiguous domains to ensure accuracy.

Continuous Re-Classification

Domains are periodically re-scanned and re-classified to detect content changes, compromised sites, and evolving web properties.

Recategorization Requests

If you believe a domain is incorrectly categorized, submit a recategorization request. Our team reviews and responds within 24 hours.
