A customer-review and rating platform operated by Expert Systems AG in Berlin, strongest in the German-speaking market and available internationally in English since 2017. A free tier exists with a capped number of displayed reviews, and the paid tiers are priced openly.
Domain Rating ist eine datierte Ahrefs-Momentaufnahme der Domain-Autorität. 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, geschätzter traffic and verweisende domains, so they are not published for any record.
A genuinely free tier exists and is presented alongside the paid ones rather than hidden, so the entry point is knowable before signing up.
Paid tiers are priced openly — the Basic plan is listed at $359.88 per year — instead of being quoted only on request.
Reviews are collected through the platform’s own surveys as well as aggregated, and the operator publishes what each tier includes feature by feature.
The company page states where the business is run from and who leads it, which is more disclosure than most review platforms offer.
Einschränkungen
The free tier is capped. The operator lists a limited number of displayed reviews and a single active survey per month, so a free profile is a sample of the product rather than a full one.
A thirty-day premium trial is offered at signup. A trial is not a free tier, and the two must not be confused when judging cost.
“ProvenExpert Profile indexed in Google” appears among the marketed features. That is the operator’s product description and is NOT adopted here — no indexing outcome is asserted.
An account is required before a profile exists, so this is not an anonymous submission.
Creating a profile is documented; claiming an existing third-party profile is not, so no claim flow is asserted.
Whether a business can respond to reviews is not documented on the pages consulted and is not asserted. A review system existing never implies a reply function.
Whether verification is required, and by what method, is not documented, so nothing about verification is asserted.
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.
Businesses in the German-speaking market wanting a review profile with an openly priced upgrade path.
Freelancers and small firms that want to collect customer feedback through surveys rather than only unsolicited reviews.
Nicht empfohlen für
Businesses needing an uncapped free profile. The free tier limits how many reviews are displayed.
Businesses whose reason for joining is search visibility. Indexing is a marketed feature, not a guarantee, and is not asserted here.

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.
