Domain Rating is a third-party metric produced by their respective providers, not by PetroHrys.com. Each recorded value carries its provider and the date it was measured. No source has been consulted for authority score, estimated traffic and referring domains, so they are not published for any record. The PetroHrys Score is a first-party editorial assessment.

The PetroHrys Score is a first-party editorial assessment, not a third-party
authority metric. It is the weighted sum of the ten factors above, divided by ten, so the number
on this page is reproducible from the values shown. Each factor is scored from 0 to 10 by a human reviewer and weighted as shown. The definitions describe what was weighed, not a rubric: no threshold or formula maps a directory onto a value, and two reviewers could reach different numbers. The score is reproducible from the factors shown on every record, but it is an editorial judgement, not a measurement.
