Bazoš
Platform · this deep dive is built from the official pages of the platform itself and of the tools that support it.
Overview
Bazoš is a Czech classifieds board, arranged as simply as possible: almost everything is free, there is no account, and an ad lives for two months. The platform describes itself as «Inzerce zdarma, internetový bazar — kup si nový byt nebo prodej staré auto» ("Free classifieds, an online flea market").
The site rests on subsection domains: auto.bazos.cz, reality.bazos.cz, prace.bazos.cz and another dozen and a half sections. The operator is not a company but a private individual: Radim Smička, IČO 65773551.
The main difference between Bazoš and a marketplace is that there is no seller storefront, no basket, no delivery and no commission on the sale. The platform brings buyer and seller together and earns from bumping ads and from contextual advertising. For a business this is more of a restriction than an opportunity: the rules directly forbid advertising the firm itself.
Who's here
The platform publishes its counters right in the footer of the home page. On the date of the check they read: total ads — 1,519,537, ads in the last 24 hours — 63,129. This is the platform's own statement, not an independent measurement, and the number changes constantly.
The platform also shows the breakdown by section openly. As an example, on the date of the check: «Ostatní» — 151,762 ads, «Oblečení» — 91,526, «Sport» — 83,621, «Stroje» — 72,368, «Práce» — 6,586. You can see that jobs and services are the smallest sections: they are precisely the only paid ones.
The interface language is Czech. The platform declares four country versions: the Czech Republic, Slovakia, Poland and Austria — bazos.cz, bazos.sk, bazos.pl and bazos.at. These are separate sites, not language switches within a single catalogue.
Getting started
There is no classic registration. The platform puts it literally: «There is no ordinary account registration on Bazos.cz». Instead there is a two-stage verification of the device and the person.
First the phone: before any action other than browsing — including posting an ad, sending a message and revealing a phone number — the device has to be confirmed by an SMS code; the confirmation lasts a maximum of 1 year and is stored in cookies. Then the confirmed phone is linked to a bank account by a non-refundable micropayment of 1 Kč. The platform explains this as a fight against fraud: a fraudster can have an almost unlimited number of anonymous SIM cards, but far fewer bank accounts.
What you can publish
Posting is free apart from two sections: publication is free, except for the sections «Práce» (jobs) and «Služby» (services), where an ad is posted using a coupon; up to 20 photographs in.jpeg format of any size are attached to each ad free of charge — they are automatically reduced to 1200×1200 pixels, and the ad itself is shown for a maximum of 2 months, after which it is deleted automatically (it can be restored within the following two months). The per-user cap: a maximum of 50 ads, and repeated advertising is forbidden and deleted automatically.
Bazoš's prohibitions are long and specific. The key one for business: users may not advertise their business activity as such; goods are listed only entirely specifically — one item, of one colour, shape, type and size, but an entrepreneur is obliged to add their name and IČO at the end of the ad, with a reference to EU regulation 2019/1150. An example from the rules themselves: an estate agency may not advertise its activity, only a specific property; a car dealership only a specific car.
How to grow
The only official promotion tool is "topping" (TOPování), that is, moving an ad up by date. It works not as a "place in the top" but as putting the clock forward: the ad's time = the time of posting + the topped time.
The return falls with every coupon, and the platform publishes the whole scale: the first coupon moves the ad by 7 days, the second by 6 (13 in total), the third by 5 (18), the fourth by 4 (22), the fifth by 3 (25), the sixth by 2 (27), the seventh and each subsequent one by 1 day (28 in total); the ceiling is 21 toppings, in the «Služby» section 7, and topping does not extend the display period. When you edit an ad, the topped position is not lost.
The price of a coupon depends on the payment method — the platform lists four: by card or through a bank account — 49 Kč including VAT; through an in-app purchase in the Android app — 59 Kč; through an in-app purchase in the iOS app — 59 Kč; by sending an SMS with the word BAZOS to the number 90709 — 79 Kč. The code is valid for 6 months. The same coupon is needed to post an ad in the «Práce» and «Služby» sections at all.
The platform does not sell banner advertising: the ad space above the listings is sold only through the Google AdWords system, we do not offer banners.
Path to monetization
The platform does not pay creators. Bazoš is not a marketplace: it does not hold the buyer's money, does not take a commission on the sale and does not arrange delivery. Payment and handover of the goods happen between people directly, outside the platform.
What exists instead of guarantees is public ratings. The platform maintains a database of buyer and seller ratings, so that people can share experience and warn about fraudsters. If a deal falls through, the platform's instruction is blunt: file a report with the Czech police, attaching a copy of the ad, the correspondence and the payment document, and add a negative rating to warn the others.
Tools and automation
Bazoš does have programmatic access, but a narrow one. The platform describes it like this: bulk automatic import (API) is available only to estate agencies for the Reality.Bazos.cz section; the price of posting one ad through automatic import is 2 Kč, the number of ads is not limited, and the retention period is 2 months. Connection is arranged by correspondence with the platform.
The same page names the supported systems, and the list is closed: Igluu, Poski REAL, Realitni-spravce.cz, REALBrána, Realitka7.cz, Realman.cz, Reego.cz, Softreal.cz, Urbium.cz. The platform offers no general API for goods categories.
Ads are managed through the «Moje inzeráty» section using the e-mail and/or phone from the ad; editing and deleting are done with the password you set when posting, and operators work in search: a minus before a word excludes it, quotation marks search for an exact phrase.
Limits and rules
- Entry. SMS confirmation of the device (valid for up to 1 year) plus a non-refundable micropayment of 1 Kč to link the phone to a bank account.
- Volumes. Up to 50 ads per user; up to 20 photographs per ad, a display period of 2 months, up to 21 toppings (in «Služby» up to 7) with a total shift of no more than 28 days; an ad that breaks the terms will be deleted by an administrator within a few minutes of posting.
- For business. Advertising a firm's activity, made-to-order goods, unlimited quantities of goods and resale is forbidden; the name and IČO must be given at the end of the ad.
- Passwords. The platform does not disclose an ad's password; it can only be sent to the e-mail given in the ad.
Who it's for
It suits a private seller in the Czech Republic who needs to sell a specific item quickly and free of charge: no account, no fee and no commission — only a one-off confirmation of a phone and a bank account. It suits estate agencies: for them there is automatic import from the nine named systems and a clear price per ad. It conditionally suits those who provide services or are looking for staff: these are the only paid sections.
It is not suitable for building a brand and a storefront: there is no storefront here, company logos and websites in ads are forbidden, and advertising the company itself is a direct breach of the terms. It is not suitable for a goods business with a range: the rules require one item of one colour and type per ad. Nor is it suitable for those who need delivery with built-in payments.
