Unmatched Coverage & Freshness

The Most Comprehensive Domain Coverage Available

Coverage matters. When evaluating a URL categorization database, the percentage of domains you can classify directly impacts your product's effectiveness. Our database is built from the ground up to maximize coverage while maintaining accuracy.

We source our domain list from multiple authoritative sources, with Google's Chrome User Experience Report (CrUX) forming the foundation. CrUX data represents real-world browsing patterns from hundreds of millions of Chrome users worldwide, ensuring our database covers the domains that actually matter to your users.

Coverage by Popularity Tier

Our coverage is particularly strong where it matters most: the domains your users actually visit. With 18 million domains sourced directly from Google CrUX data, we ensure that virtually every meaningful web interaction can be classified.

Authoritative Data Sources

Always Fresh: Weekly Update Cycle

The web changes constantly. New domains are registered, existing sites change their content focus, and previously categorized domains may shift their purpose. Our weekly update cycle ensures your categorization data stays current.

Why Coverage Matters for Your Applications

The effectiveness of any URL categorization solution hinges directly on its coverage capabilities. When your application encounters an uncategorized domain, it creates gaps in your security posture, advertising targeting, or content filtering effectiveness. Our comprehensive coverage approach eliminates these blind spots by ensuring that virtually every domain your users encounter is properly classified.

The Cost of Incomplete Coverage

Organizations using databases with limited coverage often face significant operational challenges. Security teams may miss malicious domains that slip through unclassified, advertisers may serve ads on inappropriate content, and content filters may fail to block harmful material. These failures can result in security breaches, brand safety incidents, and compliance violations that carry substantial financial and reputational costs.

Coverage Quality vs. Quantity

While total domain count is important, the quality of coverage matters even more. A database with 100 million domains that misses popular, high-traffic sites provides less value than our focused approach targeting the domains users actually visit. By building our coverage around real-world browsing data from Google CrUX, we ensure that our classification efforts prioritize the domains that matter most to your applications.

Our Technical Infrastructure for Maintaining Coverage

Maintaining comprehensive web coverage requires sophisticated technical infrastructure that can discover, analyze, and classify millions of domains continuously. Our platform combines multiple data collection methods, advanced machine learning classification systems, and robust quality assurance processes to deliver the most comprehensive and accurate domain database available.

Rigorous Data Quality Assurance

Coverage without accuracy provides little value. Our quality assurance processes ensure that every domain classification meets rigorous accuracy standards before entering our production database. We employ multiple validation layers including automated testing, statistical analysis, and human review for edge cases.

Automated Quality Checks

Every classification passes through automated quality gates that verify confidence scores, check for classification consistency, and flag potential errors for review. Our systems automatically identify and quarantine suspicious classifications before they reach customers.

Human Expert Review

For ambiguous cases, newly emerging content categories, and quality auditing, our team of trained content analysts provides human oversight. This ensures our automated systems remain calibrated and accurate even as web content evolves.

Continuous Accuracy Monitoring

We continuously monitor classification accuracy through statistical sampling, customer feedback analysis, and comparison against ground-truth datasets. Our target is maintaining 98%+ accuracy across all major content categories, with even higher accuracy for critical security and safety categories.

How Our Coverage Compares to Industry Alternatives

Not all URL categorization databases are created equal. Many competitors rely on limited data sources, outdated crawling infrastructure, or insufficient classification capabilities that result in significant coverage gaps. Our approach addresses these common limitations through superior data sourcing, advanced technology, and continuous improvement processes.

Common Industry Limitations

Traditional URL categorization providers often struggle with newly registered domains, international content, and rapidly changing websites. Their databases may contain stale data, miss emerging threats, or provide inconsistent classifications across similar content types.

Our Competitive Advantages

By sourcing our domain list from Google CrUX data representing real user browsing patterns, we ensure comprehensive coverage of domains that actually matter. Our weekly update cycle keeps data fresh, while our advanced ML classification provides consistent, accurate results across all content types and languages.

Use Cases That Demand Comprehensive Coverage

Different applications have varying coverage requirements. Security applications need near-perfect coverage to prevent threats from slipping through. Advertising platforms need comprehensive coverage to maximize brand safety. Understanding these requirements helps organizations choose the right database for their needs.

Continuous Improvement and Future Development

The web continues to evolve rapidly with new domains, content types, and technologies emerging constantly. Our commitment to comprehensive coverage includes continuous investment in expanding our data sources, improving our classification technology, and adapting to changing web landscapes.

Expanding Data Partnerships

We actively pursue partnerships with additional data providers to expand our domain discovery capabilities. This includes relationships with registrars, hosting providers, and security researchers who can provide early visibility into newly created domains.

Advanced Classification Technologies

Our research team continuously evaluates and implements new machine learning techniques to improve classification accuracy and speed. This includes exploring large language models, multimodal analysis, and real-time classification capabilities.

Community Feedback Integration

Customer feedback plays a crucial role in maintaining and improving our coverage. When customers report missing or miscategorized domains, we prioritize these for immediate review and use the patterns to improve our automated systems.
