PetroHrys Score
- PetroHrys Score
- 70
- Domain Rating
- Not measured
Domain Rating is a dated Ahrefs snapshot of domain authority. PetroHrys Score is an independent editorial assessment of the directory’s practical business value. They are separate measurements and are never combined. Domain Rating values are dated historical Ahrefs snapshots. New measurements are not collected because the Research Center does not depend on mandatory authenticated APIs. 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, and describes the domain that was measured rather than one page on it. 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, 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.
