The business catalogue operated by Seznam.cz, the Czech search company. Registration is free, a business can add a company that is not yet listed, and company profiles carry ratings — which makes it the default Czech local citation.
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.
It is operated by Seznam.cz, a.s., the Czech search company, so a profile sits inside the domestic search ecosystem rather than beside it.
Registration is free and stated as such: “Registrace je zdarma a zabere jen pár minut.”
A business can add a company that is not yet listed — the catalogue invites it directly: “Máte nebo znáte firmu, co tu není? Přidejte ji.”
Company profiles carry ratings, so the catalogue supports reputation as well as discovery.
Limitations
Creating an entry is confirmed; claiming an existing third-party entry is not documented, so no claim flow is asserted.
The catalogue distinguishes suggesting a company from adding your own, but whether the second route establishes ownership of an existing profile is not documented.
Ratings exist, but whether a business owner can respond to them is NOT documented, so no owner-response capability is asserted.
The operator states that companies are verified but does not document what is verified or how, so nothing about verification method is asserted.
A profile records what was submitted and what reviewers wrote. It is not a check that a business is solvent, licensed or currently trading, and it is not the Czech commercial register.
Czech businesses wanting the single most visible domestic local citation, tied to the country’s own search engine.
Adding a free Czech profile that carries customer ratings.
Not recommended for
Businesses assuming they can reply to ratings. Owner responses are not documented and are not asserted here.
Anyone outside Czechia. The catalogue is a Czech-market product.

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.
