The formula, in public

How listings are ranked

Every company is scored out of 100 on six checks. The formula is below in full, because a ranking you cannot inspect is just an opinion with a number on it.

What the score is not

It is not a rating of workmanship. It counts records, and a record cannot tell you whether a crew turned up on time. A low score usually means a company keeps little public information, which is a different thing from doing bad work, and every page says which of the six checks came up short rather than hiding the deduction in a total.

Paid placement

Sponsored slots sit above the ranked list, never inside it, and are labelled as sponsored. The organic order is the verification score and nothing else. A company cannot buy a point, and information a company tells us about itself does not earn one either. Only a record we can read ourselves does.

Claiming

Claiming a listing is free, involves no sales call, and does not change the score. It exists so the business can correct what is wrong.
