Datafeed files

A website categorization database is a database that classifies and categorises websites based on their content, purpose and other characteristics. The purpose of website categorization is to provide users with information about the nature of a website, helping them to make informed decisions about accessing or interacting with it. Our Website Categories Database supports 84 categories.

The dataset comes in the two following forms

1. Daily Website Categorization Datafeed

The entire website categorization database is updated daily at 06:00 UTC.

Data for Daily Website Categorization Datafeed is obtained from Newly Registered Domains Data Feed. This approach helps to keep the database up to date.

File Gzip size Unpacked size Rows
categories.%DATE%.daily.csv.gz 50MiB 250MiB 1.5M
categories.%DATE%.daily.json.gz 60MiB 500MiB 1.5M

2. Custom Website Categorization Database

You can configure your own dataset with your desired categories and countries. All updates from the Daily Website Categorisation Datafeed are guaranteed to hit the dataset for at least 24 hours after the daily release.
