Austria’s principal business and telephone directory, operated by HEROLD Business Data GmbH. A company entry is free, and the same form is used both to create a new entry and to claim an existing one — the operator names both routes explicitly.
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. Domain Rating is a dated historical measurement of the shared domain, not an assessment of this individual registry page. New measurements are not collected because the Research Center does not depend on mandatory authenticated APIs. Where several registries are published on one measured domain they repeat that domain’s single dated snapshot rather than each carrying a figure of its own. 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 entry is free and the operator says so in the page’s own heading: “Kostenlosen Firmeneintrag auf Herold erstellen”.
Both routes are named by the operator, which is why this is recorded as create-and-claim: “Eintrag hinzufügen” and “Eintrag beanspruchen”, alongside “Eintrag verwalten” for managing it afterwards.
The operator describes the platform as “Österreichs größtem Branchen- und Firmenverzeichnis”, and identifies itself in the footer as HEROLD Business Data GmbH.
One form handles creating and claiming, so a business that is unsure whether it is already listed does not have to guess.
Limitations
The operator markets “Besseres Google-Ranking” as a benefit. That is a marketing claim and is NOT adopted here; no ranking outcome is asserted.
Whether verification is required, and by what method, is not documented, so nothing about verification is asserted.
No review system or owner-response function is documented on the pages consulted, so neither is asserted. Absence here means unrecorded, not unavailable.
The free entry sits alongside paid promotion products, so the operator has a commercial interest in upselling after submission.
No Domain Rating is published for this platform. No valid measurement exists in the frozen historical set and none may be estimated, so the metric is recorded as not measured rather than guessed.
A listing is a directory entry. It is not evidence that a business is solvent, currently trading, licensed, or checked beyond what the operator documents here.
No ranking, indexing, traffic or lead outcome is asserted. The operator markets outcomes; this record does not adopt them.
Austrian businesses wanting a free entry in the country’s best-known directory.
Businesses that are already listed and want to take control of the entry rather than create a duplicate.
Not recommended for
Businesses outside Austria. The directory is organised around Austrian regions.
Anyone expecting the operator’s Google-ranking claim to be a commitment. It is marketing.

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.
