How we chose these
We rank every active provider in every home-service business with a verified address in Rancho Bernardo / Black Mountain (ZIP 92127) by a composite ServiceAgent Score (0-10) made up of two components:
Trust Score (40%) - rewards owner-verified status, completeness of contact info, presence of hours/coordinates/photos, and review-volume credibility.
Recommendation Score (60%) - Google rating Bayesian-shrunk toward the category mean using a 25-review prior so high-volume providers can't be dethroned by 5-star outliers.
Composite ServiceAgent Score = 0.6 × Recommendation + 0.4 × Trust. We re-compute as new reviews land and as providers claim their listings. The "Last updated" date at the top of this page reflects the most recent data refresh.
What we deliberately don't do: pay-to-rank, sponsored slots that masquerade as editorial picks, or hide our formula. Sponsored slots (if/when introduced) will be clearly labeled and won't affect editorial ranking.
