How firms are placed on the matrix

Every position on this chart is the output of the Goodfirms ranking algorithm - a weighted composite of signals across two axes. The algorithm is recomputed regularly and is fully documented.

Sponsorship does not affect placement. PRO members receive visible badges and ad placements, but their algorithmic scores are calculated identically to free listings.

Read the full methodology

Algorithm at a glance

X-axis (Core Competencies): Service Focus Ratio + Portfolio Depth + Quality + Experience

Y-axis (360-Performance): Client Reviews + Market Presence + Goodfirms Score

Missing signals are excluded from a firm's score, not substituted with defaults - weights redistribute across remaining inputs

Recency decay over the last 18 months keeps stale reviews from dominating
