Add original data or first-hand expertise

Original data and first-hand experience are the hardest parts of E-E-A-T to fake. Publish test results, benchmarks, screenshots or interviews, state sample size and date range, and cite primary sources. Update the data when it changes and keep past versions verifiable.

How to apply it

  1. Choose a question you can answer with data General best practice

    Pick a question customers ask that requires access you have: account benchmarks, product tests, support ticket patterns. Define the method before collecting.

    Check: A written method exists with sample size, date range and inclusion criteria.

  2. Publish the evidence

    Present results in tables or charts with units, note limitations, and link primary sources. Attribute the work to a named author with credentials.

    Check: The page states sample size, date range, method and author, and every statistic has a source or a method note.

  3. Keep it current and archive it General best practice

    Update the dataset when conditions change and keep an archive of previous versions with dates so readers can verify claims over time.

    Check: The page links to at least one dated previous version and shows the current data date.

Keep datasets in the repository as JSON or CSV and render tables from them, so the page and the downloadable data cannot diverge.
