Data methodology
How Slot Data Hub builds the database
Our pages are generated from structured records and refreshed automatically. The goal is to expose available fields clearly without inventing missing game information.
Primary data source
The current catalog is synchronized from slot.report. Source timestamps are preserved where available, and each local record also stores the time it was synchronized into this database.
Normalization
Provider aliases and common taxonomy variants are normalized so equivalent names can be grouped under one public page. Source records that clearly represent the same provider, title and release are collapsed into one canonical slot record, while former duplicate slugs are retained as redirects. Compound or malformed theme and mechanic values are cleaned before storage, and generic or unusable category values are excluded from public taxonomy pages.
Indexation quality rules
A slot page is eligible for search-engine indexation only when at least three substantive data points are available from RTP, volatility, maximum win, release date, theme, mechanic, grid and listed features. Thinner records remain accessible but use noindex,follow and are excluded from the XML sitemap.
Theme, mechanic and volatility category pages require at least five matching games to be indexable and included in the sitemap. Search, sorting and filter combinations under the slot directory use noindex,follow and canonicalize to the main directory.
Refreshes and corrections
The catalog refreshes automatically. A visible “Data updated” date on each slot page reflects the local synchronization timestamp. Because suppliers and operators can change game configurations, important values should still be checked against the in-game information for the exact version being played.
