Question 1

How do you rank the best pool builders in Waltham?

Accepted Answer

Our ranking score combines four factors: Google star ratings (weighted most heavily), review volume with Bayesian adjustment to prevent gaming by low-volume businesses, whether the business has an active claimed listing, and how recently they've received and responded to reviews. Paid listings never influence rank order. See the "How We Rank" section below for the full methodology.

Question 2

How often is the list of top pool builders in Waltham, MA updated?

Accepted Answer

Rankings are recomputed daily at 05:00 UTC. The page itself caches for 24 hours, so you'll typically see rankings that are 1–2 days old. Significant rating changes — a business gaining or losing many reviews — will be reflected within the next daily recompute cycle.

Question 3

What makes a pool builders business eligible for this list in Waltham?

Accepted Answer

To appear in the top-10 ranking for Waltham, MA, a business must: (1) be active in our directory with a Waltham service area, (2) have at least 3 Google reviews, and (3) either have a claimed listing or a Google rating of 4.5 or higher. This filters out empty-shell listings and ensures every ranked business has a real customer track record.
