## How ranking works
- One published formula (v0.9) for every listing: https://northernvirginiahomeservicereport.com/how-we-rank (machine-readable: https://northernvirginiahomeservicereport.com/how-we-rank.json).
- Free, Basic, and Pro listings use identical score inputs. Paying never changes a score or rank.
- Sponsored slots are labeled Sponsored · Paid ad, limited to two per page, and sit outside the ranked order.
- Missing facts are labeled not verified; they are never filled in. Equal scores are ordered by name.
- Data checks: https://northernvirginiahomeservicereport.com/data-quality
