This page describes where the data in our catalog comes from, how we check it, what conditions a page must meet to be indexed by search engines, and what criteria our rankings are based on — in line with the obligation to disclose the main ranking parameters under the Omnibus amendment (Article 12(1)(9a) of the Polish consumer rights act).
1. Where the data comes from
The primary source is official manufacturer material: datasheets, press releases, product pages and declarations of conformity. Price data comes from the offers of Polish distributors and shops and, where there is no domestic offer, from the manufacturer's official price lists in other currencies, clearly marked as foreign prices. For prices we give the source and the date. If a value is not given by any reliable source, the field stays empty — we do not estimate or interpolate missing specifications. The exception is prices: where a manufacturer publishes no price and the sources give only a range, we show the midpoint of the range and mark it as an estimate. The manufacturer is always the preferred source; sellers' websites and aggregator sites are treated as secondary sources and are marked as such when a price or parameter comes only from them. The label “Manufacturer price” means a price taken from the manufacturer's own site; prices from foreign sellers and aggregators carry their own labels (“indicative price”, “price from an aggregator”).
2. How the texts are written
Editorial texts are prepared with AI tools on the basis of collected sources and are then organized and corrected by the editorial team. The English edition is a translation of the Polish edition. Conflicting data from different sources is noted with a remark on the discrepancy instead of silently choosing one value. Numerical facts from technical specifications are taken from datasheets; manufacturers' marketing descriptions are rewritten in our own words.
3. How we check the data and how many errors we found
We check data against primary sources on a sample basis, not page by page. In two rounds of checks (as of 28 September 2026) we compared a total of 310 models with manufacturer material: 60 models in the first round (74 discrepancies), 250 models in the second (256 discrepancies). That is 330 discrepancies in total, about 1.1 per model checked; the most common causes were figures taken from aggregator sites instead of the manufacturer's page, mixed-up variants of the same model, and old or wrongly converted prices. We correct the errors found as we go, but we cannot rule out that more remain in the catalog — which is why we ask for reports (section 7).
4. Quality threshold before publication
A page is not offered to search engines merely because it exists. Every page goes through an automatic content check. A model page must have, among other things, at least 6 confirmed specification fields, an editorial description of at least 120 words and at least one source with a URL; concept models are published only if the manufacturer has documented funding or a production announcement. Manufacturer, comparison, ranking, category and use-case pages and company directories have separate thresholds for length and own content. A page below its threshold remains accessible to readers but is not promoted in search results or in the site's page index until we complete it; very thin directory entries are not published as separate pages at all. We prefer fewer pages with full content to many incomplete ones.
5. Ranking criteria
Rankings (for example "ranking of humanoid robots") are based on openly weighted criteria, which each ranking lists on its own page with the weights: completeness and currency of specifications, payload or performance relative to price, availability in Poland, and the manufacturer's documented market history. No place in a ranking is bought — paid or sponsored positions, should they ever appear, will be clearly labeled "Sponsored" and kept separate from the ranking based on objective criteria. Funding details are described in How we make money.
6. Update cadence
We check prices and availability at distributors periodically (for many models manually or semi-automatically); the date of the last check is shown next to the price. Specifications are updated whenever we notice a change in the manufacturer's datasheet or a user reports one. The "Updated" date on a page means the last change to that page's content or to the state of the data it is based on — not the date of an automatic rebuild of the site.
7. Report an error
Found an outdated price, a wrong specification or a model that no longer exists? Write to editor@robolupa.com (see Contact) — we check every report manually at the next update of the entry concerned.
