A comparison page written by a vendor can easily be an ad with a table. The three below are held to a stricter rule: every competitor claim was independently verified in September 2026 or re-checked in October 2026 — prices, trial and refund terms on the vendor’s own site, review scores on Trustpilot; each page dates its claims and links its sources; anything we could not verify is stated as unverified rather than guessed; and each page ends with a candor section — genuine cases where the competitor is the better pick.
