#1 to #25 are shown in full above. Here are #26 to #50, in CR Score order; each links to its profile.
Emergency lists move 10 points of the CR Score from reputation to availability: 15% and 15%. Availability credits 24/7 hours, same-day service, weekend hours and weekly open hours. 24/7 electricians are listed first, then same-day, then the rest; ranks follow that order. Paid placement never changes a rank.
Paid placement never changes a rank or score. Featured businesses are paid, labelled, limited to 3 and shown above the ranking, outside it.
