Methodology & data sources
Each ranking is stored as a JSON file in our repository. The page renders that file and shows the source name, URL, period, and last-updated date above the table.
Update policy
- We refresh a ranking when the cited source publishes a new period (monthly, quarterly, or annually, depending on the source).
- If the official PDF is delayed, we may use a reputable secondary report of the same release and note that on the page.
- We do not backfill missing ranks with guesses. Short lists stay short and are labeled as such.
- Market share or other fields are left blank when we cannot verify them.
Current ranking sources
Third-party traffic and market-share estimates (for example Semrush or Omdia) are labeled as estimates on their pages. Logos are for identification only and remain the property of their owners.
