Domain Rating
73Ahrefs snapshot, measured

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.

Évaluation

Points forts

  • The population is stated plainly: the platform describes itself as covering “600.000 B2B-Anbieter” and as “der meistbesuchte B2B-Marktplatz für den professionellen Einkauf in der DACH-Region”.
  • Profiles carry product data, not just contact details, which is what a procurement search actually needs.
  • Its reach is regional rather than national — Germany, Austria and Switzerland — which suits suppliers who already sell across DACH.

Limites

  • Whether a basic profile is free is NOT documented. A premium profile is offered on request, but the existence of a paid tier does not establish that the basic tier is free, so cost is recorded as unknown.
  • It is a B2B marketplace. Presence here says nothing about local or consumer visibility, and it is the wrong platform for a business whose customers are the public.
  • Supplier badges indicate that some verification exists, but the operator does not document what is required or how it is checked, so nothing about verification is asserted.
  • No review system is documented, so neither reviews nor owner responses are asserted.
  • Coverage is described as the DACH region rather than Germany alone, so a record filed under Germany understates its geography. The dataset does not yet carry a machine-readable coverage field, and this is stated in prose instead.

Establishing required submission assets requires submitting a listing and observing the result. That has not been done for any directory in this dataset, so it is not published rather than estimated.

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.
