Website Categorization Database | 25+ URL categories | WhoisXML API

#1 website categorization database with 25+ web categories

We provide a well-structured database of domain names classified into 25 different categories with their owners’ contact information. Data is processed by a machine learning (ML) engine that scans the websites’ content and retrieve their meta tags. Categories are then assigned to each website using natural language processing (NLP).

Website Contacts & Categories Database

Our URL categorization database is:

  • Precise and relevant

    Our web crawlers use a combination of advanced ML algorithms and human assistance to parse web pages. That allows us to retrieve contact information for domains without the costs and trouble associated with web scraping or manual research to meet your site classification requirements.

  • Consolidated and coherent

    All of the information we provide is well-parsed and normalized to a consistent format for easy integration into business processes. Get both parsed and raw data via a database download in MySQL and comma-separated values (CSV) files.

  • Easy to correlate

    You can also combine Website Contacts & Categorization Database with our WHOIS Database Download to obtain WHOIS records containing contact information, registrant details, and more for any domain under all 25 categories.
