External codes

Generally, external display and tracking codes, which comply with the rules listed below, are accepted. Seznam.cz reserves the right to reject the codes which do not comply with the conditions of standard functionality or are not on the list of supported code types.

General rules for external codes

  1. External display and tracking codes must support HTTPS. The URL addresses for loading images, styles, libraries, tracking scripts, etc. must be prefixed with two slashes (see example below).
    <script src="//gdecz.hit.gemius.pl/gdejs/xgde.js"></script>
  2. External codes must not cause errors on the parent site (neither in the JavaScript console nor visibly).

Rules for external display codes

Only certified external display codes can be used within the Seznam.cz advertising space (see list below).

It is not possible to deploy a non-supported code type for Direct Sales from 1. 5. 2021.

The restriction does not apply to products “Interaktivní plánovač” and “Kalkulačka” for which specific requirements are required (see detail TS).

Design requirements

  1. Banners loaded through external codes have to be sufficiently visually distinguishable from the page content for the whole time of their display (even if they are animated), e.g. by using a frame, a background color, etc. The frame and/or the background should be straight and even, not warped, distorted, or otherwise modified.
  2. A creative that expands beyond its standard position must contain a button marked with a cross and the word “Zavřít” (Close), located in a prominent place. The location of the button depends on the advertisement product specification.
  3. Target links must be opened in the parent (or new) window through the target="_ top" or target="_ blank" attribute.
  4. Should the banner be sold for PPC (pay per click) and displayed using an external code, it must allow external code to add our tracking URL (eg. using a "click" parameter – see example below).
    <script src="//t**k.a****m.n*t/a*****t/?bn=6*******9;click=__SHORT_CLICKTHRU__&destination="></script>
    <script src="//t**k.a****m.n*t/a*****t/?bn=6*******9;click=__SHORT_CLICKTHRU_ESC__%26destination%3D"></script>
    <iframe name="CPbanner*******" src="//t**k.a****m.n*t/a*****t/?bn=6*******9;c**s=*;ord=[timestamp];click=__SHORT_CLICKTHRU__&destination=" width="300" height="250" frameborder="0" scrolling="no"></iframe>
    <iframe name="CPbanner*******" src="//t**k.a****m.n*t/a*****t/?bn=6*******9;c**s=*;ord=[timestamp];click=__SHORT_CLICKTHRU_ESC__%26destination%3D" width="300" height="250" frameborder="0" scrolling="no"></iframe>
    It is necessary to get the value of the 'click' parameter and insert it in front of your own escaped target URL address.

Notice

  1. Banners delivered through external codes must not use too many of the user's system resources. If the advertisement is using too many system resources, browsers may automatically block it and won't display it.
  2. External display codes must support asynchronous ad delivery.
  3. All banners issued through the external advertising system may additionally be identified only by a simple small icon of a partner without any additional text (the only accepted text being "Volba reklamy" or "AdChoices").

Additional information

If the requested code is not among the supported types, you can request a certification. In this case, the co-operation of the supplier (developer) of the code will be needed to provide the details of the code and to implement the requirements of Seznam.cz.It is only possible to add a new partner (or a supported type of code) after checking the functionality and a deploy test. Based on the cooperation of the code provider and the complexity of the implementation, a time buffer for certification is needed (about one month) before the planned launch of the campaign.

Rules for external tracking codes

Direct saleA maximum of two external tracking codes can be deployed within a single banner, unless specified otherwise for a given product. The allowed combinations are: 2 URLs with a 1×1 px tracking image or 1 URL with a 1×1 px tracking image + 1 tracking JavaScript.
