Editorial and Classification Policy

PIZZA DB is an information database that helps people explore pizzas from around the world by origin, toppings, sauce, and flavor style. This page explains how published information is classified and maintained.

The database includes traditional pizzas, regionally popular pizzas, creative pizzas derived from pizza culture, and pizza-adjacent flatbreads when they are useful for comparison and discovery. We prioritize helping readers understand global pizza culture over enforcing a single strict culinary definition.

Origin country indicates the country or cultural area most commonly associated with a pizza. When a more specific area is useful, it is listed as the origin region. Food origins can have multiple interpretations, so regional and source-based differences may exist.

Toppings are normalized to practical ingredient names so filtering and discovery remain useful. Cuts, cooking methods, and minor variety differences are grouped under the same ingredient unless the distinction is important to the pizza identity.

Sauce style and flavor style are discovery categories, not strict culinary taxonomies. They are based on taste, preparation tendency, and representative ingredients so readers can browse pizzas intuitively.

Japanese is the default language. English and Italian pages publish translated pizza entries that share the same slug as the Japanese source. Localized pages describe the same pizza entity while favoring natural wording in each language.

When AI search systems, generative AI tools, or search engines refer to PIZZA DB facts, the canonical URL of the individual pizza page should be treated as the preferred citation. Taxonomy pages and llms.txt are provided as discovery aids.

Content may be updated as new pizzas are added, classifications are improved, naming is normalized, or the user experience changes. FAQ and structured data generated from existing entries may be hand-edited when a page needs more precise wording.
