A Know Well Ranking page is designed to present relative performance and tiered outcomes under a specific topic. Because different Ranking pages may target different types of entities, the measured dimensions and indicator system for a given Ranking should be interpreted strictly according to that page’s “Methodology / Indicators” section.

We convert publicly verifiable information into structured indicators and compute and aggregate them according to the methodology defined on the specific Ranking page, producing a comparable relative ordering or tiered result. Where a multi-level indicator system is used, we generally follow the logic of “standardize bottom-level indicators, aggregate upward with weights, and then produce the final rank or grade.” The number of indicator levels and whether grades are displayed are determined by the page’s stated rules.

Coverage and inclusion criteria vary by Ranking page depending on the topic, data availability, and methodological design; therefore, we do not apply a single fixed standard across all rankings. Each page will disclose, under “Scope / Updates” (or equivalent), the number of entities included for the current version, the entity types and geographic/industry scope, the sampling time window, the screening rules, and any potential version changes that affect coverage.

In principle, we use only publicly verifiable information sources—such as official websites, public notices, press releases, public data portals, and other channels that can be accessed and verified by third parties—and we use automated workflows to locate sources and extract them into structured indicators while requiring that results map to reviewable evidence. Non-public data is not used as a standard input for rankings, and we do not accept private materials as a substitute for public evidence in a way that could affect ranking outcomes. In rare cases where restricted-access data is used with explicit authorization and a verifiable compliance basis, we will disclose its nature, authorization basis, and verification path in the page’s “Data Sources / Methodology” section and ensure such use does not weaken verifiability and fairness.

Weights are typically determined based on the stated methodology, considering indicator importance, availability, discriminative power, and stability, and may incorporate completed weight-optimization or finalized scheme settings to define the disclosure level for external publication. Disclosure granularity can differ by Ranking page; please refer to the page-specific explanation. If you have concerns about weights or indicators, you may contact us at support@know-well.org.

Any system built on indicators, data, and weights can create systematic advantages or disadvantages for certain types of entities under certain dimensions; Know Well’s principle is to keep such bias risks explainable and reviewable. Within the same Ranking, we apply consistent indicator definitions, data standards, cleaning, and standardization rules; we cross-check sources and validate anomalies where applicable; we handle missingness and uncertainty under explicit rules and provide appropriate update/coverage cues when feasible; and we conduct basic robustness checks before publication to assess how sample changes, data updates, or method adjustments affect the results—if a setting proves overly sensitive or unstable, we will revise it at the methodological level.

A Ranking should be treated as an informational reference rather than a single decisive standard. It reflects relative position within a specific topic dimension and is most suitable for initial screening; final decisions should still be made by combining multiple sources of information such as personal needs, budget, risk preferences, and usage scenarios.

Yes. Know Well welcomes reasonable citation and dissemination of ranking results, provided the information remains accurate and is not presented in a misleading way. When citing or reposting, please retain the Ranking name, version or measurement window, and publication date or access date, and, where possible, link back to the original Ranking page for verification. Do not take content out of context, alter charts, replace entity names, or present the Ranking as “official certification,” “the only standard,” or make claims beyond what the page’s methodology supports; if used in promotional materials, we recommend clearly labeling the source and version, and any large-scale reproduction, removal of source attribution, or resale/redistribution requires prior authorization in accordance with the site’s copyright and usage terms.

You may submit verifiable evidence (such as an official webpage link, a screenshot of a public notice, or other authoritative sources) and contact support@know-well.org. We will review the evidence and make necessary corrections. If the matter concerns copyright or infringement complaints, please follow the website’s copyright complaint process and email copyright@know-well.org.

Update frequency depends on the data-source refresh cycle and the page’s topic. If there are changes such as sample expansion/reduction, indicator adjustments, weight-rule changes, or display-rule adjustments, the page will disclose them through an “Update Notes / Version Notes” section.
