How are these Google Ads agencies ranked?
By Bayesian-weighted score: (m·C + R·v) / (m+v), where R is the agency's mean rating, v its verified review count, C the site-wide mean, and m a confidence constant. Low-volume agencies cannot leapfrog consistently well-reviewed peers.
Can agencies pay to rank higher?
No. Listings are free, rankings accept no payment, and claimed profiles get no ranking privileges. The same formula applies to every agency in the directory.
