Rankings are computed, never sold. No agency can pay to appear higher, and we take no money from the agencies listed. The default order uses a credibility-weighted score rather than the raw star average: a rating only earns its full weight once there is a real volume of reviews behind it, so a perfect 5.0 built on two or three reviews does not outrank a strong score backed by hundreds. That correction matters, because most agencies in this index sit at or near a perfect 5.0, which makes the star average on its own close to meaningless. See the full ranking methodology.
