What Is a Website Category Lookup?

A website category lookup is an online service that identifies a specific domain name’s category. It utilizes various technologies like ML and NLP combined with human validation to analyze the content and characteristics of a site. By examining factors like keywords, structure, and other indicators, the lookup tool determines the domain’s appropriate category.
