For the the open RTB auction the advertising spaces under the Czech Publisher Exchange use a unified second level domain CPEx.cz. (The ad space with fully transparent URLs is available for the advertisers through private marketplaces.) This domain is further divided into subdomains according to the content type, so that the advertiser can choose the context in which the advertising will be displayed according to the specific requirements.

  • a.cpex.cz – the highest quality websites in our portfolio, with editorial content, “the family jewels” safe for advertising every brand.
  • b.cpex.cz – other websites with editorial content including tabloids, catalogs and advertising (including vertical advertising such as motoring or real estate).
  • c.cpex.cz – services and moderated UGC.

Information on specific media in these categories can be found under Media involved.
