How this database is built
Hotels methodology
Every number on this site is traceable to a primary source. Here is exactly how it gets here — and what we will never publish.
Sources
All facts come from each platform's own merchant documentation — official pricing pages, help-center articles, and merchant agreements. We record the exact source URL and the date we read it for every fact. We never use third-party estimates as data.
Extraction and verification
Facts are recorded from the source pages with the exact URL and the date they were read. Every fact is checked against its source before publication and re-verified on a schedule; unverified facts never appear on the site or in the sitemap.
Collection practices
Collection is low-volume and identified. Our fetcher announces itself (AccessorialIndexBot, with a contact address), honors robots.txt rules and crawl delays, fetches only public, no-login documents, and treats any block as a no — blocked sources are checked manually or not at all, never worked around. If a source objects, we stop fetching it.
Change tracking
When a source document changes (a pricing or policy update), we don't overwrite history — the prior value is retained with its effective window, and the change appears in Updates. Pages show both the source's effective date and the date we last verified it.
Corrections
Spot an error? Email help@thegoodindex.io with the page and the source you're looking at — corrections ship in the next publish cycle.
This site is an independent reference operated by The Good Studio, makers of Booked. Data is informational only and not pricing advice — always verify against the source's current published document before relying on it.
