Domain Rating est un instantané daté d’Ahrefs de l’autorité du domaine. PetroHrys Score is an independent editorial assessment of the directory’s practical business value. They are separate measurements and are never combined. Domain Rating is measured by Ahrefs and read through their public Domain Rating API. Each value carries the date it was read and describes the whole domain that was measured, not the individual page it appears beside. Where several records are published on one measured domain they repeat that domain’s single dated reading rather than each carrying a figure of its own. A record shown as not measured is a record nobody has a reading for, which is not the same as a record measured at zero. 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, trafic estimé and domaines référents, so they are not published for any record.
