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.
