How is this ranking worked out?

Each firm's position comes from its client reviews and its profile, blended into one score:

  • Rating, smoothed so a single five-star review cannot outrank a firm with hundreds of good ones
  • Review volume, with diminishing returns
  • Profile completeness: the details a buyer needs to judge the firm
  • Earned trust: verification and awards, as a small lift

No firm can pay for a position. Sponsored listings are labelled and shown apart from this list. How rankings work
