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.

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

How the heatmap is built

Every cell in the grid above is the count of firms in (place × hourly-rate tier). Firms are placed by their published hourly rate; those without a disclosed rate are not plotted.

Top company names per cell are surfaced by Value Score - a weighted blend of affordability (50%) + rating (35%) + review volume (15%).

The "Best" ribbon marks the cell in each row where firm density, ratings, and affordability line up best - the densest, highest-quality combination.
