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:

Apparel & Accessories 226
Home & Garden 115
Sporting Goods 50
Health & Beauty 46
Hardware 37
Electronics 30
Animals & Pet Supplies 25
Office Supplies 19
Food, Beverages & Tobacco 13
Toys & Games 13
Business & Industrial 10
Baby & Toddler 6
Luggage & Bags 6
Arts & Entertainment 4
Software 4
Furniture 4
Religious & Ceremonial 3
Mature 2
Cameras & Optics 2
Media 1
Vehicles & Parts 1

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.
