Data collection: sources, snapshots, check dates and how errors are fixed

When two sources disagree, the higher one wins.

1. The GRAI licence register, for who holds a licence, of what type and until when.
2. The operator's own public pages, for terms, payments, safer-gambling tools and support.
3. The Gambling Regulation Act 2024, its commencement orders, Revenue and the ASA Code, for rules.

Statements by third parties, including other comparison sites and AI assistants, are not accepted as facts. They can be the subject of a claim check, such as Can you trust betting site rankings?

Bottom line: the register outranks the operator, and the operator outranks everyone else.

Each fact goes into the fact-log with five items: the source name, the address, the check date, a quotation of up to 25 words, and a hash of the saved snapshot.

A hash is a short code calculated from the saved page. If the page changes, the code changes, so a later reader can tell whether we looked at the same text.

When a fact changes, the old record is kept and the new one points back to it. That chain feeds the terms change tracker.

Bottom line: no figure appears without a source, an address and a date.

Each kind of fact has a re-check interval and a limit. The limit is the longest a fact may stay on a page without a new check.

A removal from the register, or GRAI news about an operator, triggers a check at once. The operator leaves the matrix straight away.

Bottom line: the shortest limit among a page's facts sets how frequently the page is re-checked.

A page with a fact past its limit shows this notice: "Some figures on this page are past their check date and are being rechecked." If the fact cannot be re-checked, the page is taken down.

The date in the sitemap changes only after a real edit. Every edit goes into the changelog, and register differences go into the register log.

Bottom line: an old fact is flagged or removed; it is never quietly left in place.

Report an error through the corrections page. We aim to correct a confirmed error within two working days, and the fix is logged with the old and new values.

If the error changed a score, the score is recalculated and the change is recorded.

Bottom line: confirmed errors are fixed within two working days and logged.

We do not place bets, open accounts or deposit money. Everything on the site comes from public pages.

Pages that cannot be opened from Ireland, or that need a login, are marked "Could not be verified on ". That is not the same as "does not exist".

The GRAI register has limits of its own. Cards load by script, so we need a browser or the register's CSV export. Downloading the export needs the site owner's consent.

The Domain Names field was empty in all 40 business-to-consumer cards on 6 November 2026. A domain is therefore tied to a licensee by the licence number the operator shows.

The register can also be incomplete or contain typos. Differences are logged.

Bottom line: public pages only, no tests, and gaps are labelled as gaps.
