Website and product categorizations

What Is Website Categorization?

Website categorization is a task of classifying website into one of predefined categories, also called taxonomies. Usually this is done by a supervised text classification machine learning model, because in deployment to production one often needs to classify a large number of texts.

Typical website categories

How many categories are in the taxonomy depends on the problem. E.g. in ecommerce setting the top Tier 1 level of categorization usually has 21 categories:

Then, on lower Tiers, the google product taxonomy has 190+ categories on Tier 2 and 1000+ categories on Tier 3.

Most usually website categorization is available as API or tool. In this way one can easily integrate it in own products and services.
