Standards
Editorial Policy
Every page on CasinoPerflyn follows the same rules: primary sources first, exact quotations, dated citations, clear labels for examples and lab data, and visible corrections.
Sources
- Definitions, thresholds and recommendations come from primary documentation: Google Search Central, web.dev, Chrome for Developers, W3C, IETF RFCs and MDN Web Docs.
- Web-wide statistics come from named datasets, such as the HTTP Archive Web Almanac, with the data period stated.
- Each source is listed at the end of the page with its last-updated date, or "no date shown".
- Quotations are copied exactly. Paraphrases keep the source's meaning and scope.
The full list of source types is on the data sources page.
Checks before publication
- Every factual sentence is matched to a source opened on the checking date.
- Every number is checked against the source, including units and the period it covers.
- Code samples are reviewed for correctness and marked as illustrative.
- Automated checks run on every build: titles, descriptions, headings, links, structured data, banned phrasing and the content security policy.
Labels
- Lab and field. Any performance number says whether it comes from real visits or a lab test.
- Examples. Example budgets, worked examples and illustrations are labeled as such. The sample analysis uses invented numbers and says so at the top.
- Limits. Guides end with a "What we did not test" note.
AI-assisted drafting
We use AI tools to help find sources and prepare drafts. AI output is never published without a human-led check of every fact against its source. AI tools are not credited as authors.
Independence
No operator, vendor or tool provider pays for coverage or reviews pages before publication. The owner's commercial interests are stated on the disclosure page.
Corrections
If you find an error, send the page address and a source through the contact page. Confirmed errors are corrected promptly. Substantive corrections are noted at the end of the page with the date, and the page's update date changes.
Responsible gambling
We write for professionals and never for people under the legal gambling age. We do not advise operators to delay, shrink or hide safer gambling messages, age notices or licensing information to improve a metric. Help services are listed on the safer gambling page.
