How to block third-party codes & cookies if no consent is given?
The CMP can postpone the load of ads on your website until consent is given. In order to enable this feature you need to change existing creative codes on your website.
Please note that blocking / postponed loading only works with asynchronous script codes and Iframe codes and not with synchronous script codes.
Iframe-Codes
If you want to postpone an iframe code, please follow these steps:
- Change the
src="…"attribute of the iframe todata-cmp-src="…" - Add a new
src="about:blank"attribute to the iframe - If a
class="…"exists, addcmplazyloadto the value. If class does not exist, add the attribute including the valueclass="cmplazyload" - Add a new attribut
data-cmp-vendor="x"and/ordata-cmp-purpose="x"in order to fire the code only if consent for this vendor and purpose is given. See info below.
Example code before change:
<iframe width="300" height="250" noresize="noresize" scrolling="no"
frameborder="0" marginheight="0" marginwidth="0"
src="http://adserver.de/?x=1&y=2"
ALLOWTRANSPARENCY="true"></iframe>Example code after change:
<iframe width="300" height="250" noresize="noresize" scrolling="no"
frameborder="0" marginheight="0" marginwidth="0"
class="cmplazyload"
src="about:blank"
data-cmp-vendor="123"
data-cmp-src="http://adserver.de/?x=1&y=2"
ALLOWTRANSPARENCY="true"></iframe>asynchronous Script-Codes
If you want to postpone the load of an async. Script code, please follow these steps:
- If a
src="..."exists, change thesrc="…"attribute of the script todata-cmp-src="…" - If a
type="..."exists, change its value totext/plain, otherwise add the attribute with this valuetype="text/plain". - If a
class="…"exists, addcmplazyloadto the value. If class does not exist, add the attribute including the valueclass="cmplazyload" - Add a new attribut
data-cmp-vendor="x"and/ordata-cmp-purpose="x"in order to fire the code only if consent for this vendor and purpose is given. See info below.
Example code 1 before change:
<ins class="asm_async_creative" style="display:inline-block; width:300px; height:250px; text-align:left;"
data-asm-host="ads.adspirit.net" data-asm-params="pid=395&wmid=525&nvc=1"></ins>
<script src="https://ads.adspirit.net/adasync.min.js" async type="text/javascript"></script>Example code 1 after change:
<ins class="asm_async_creative" style="display:inline-block; width:300px; height:250px; text-align:left;"
data-asm-host="ads.adspirit.net" data-asm-params="pid=395&wmid=525&nvc=1"></ins>
<script class="cmplazyload" data-cmp-vendor="123" data-cmp-src="https://ads.adspirit.net/adasync.min.js" async type="text/plain"></script>Example code 2 before change:
<script type="text/javascript">
console.log("do something here");
</script>Example code 2 after change:
<script type="text/plain" class="cmplazyload" data-cmp-vendor="123">
console.log("do something here");
</script>Additional attributes
The following additional attributes can be added to script/iframe codes in order to further align the delivery to certain consent results:
|
Attribut |
Description |
|
|
if present, CMP will hide the iframe if consent is not given and unhide the iframe if consent is given |
|
|
CMP will only activate this script/iframe if consent for vendor |
|
|
CMP will only activate this script/iframe if consent for purpose |
|
|
CMP will display a preview (see dynamic content blocking) element in this position. |
Note: If data-cmp-vendor="..." and data-cmp-purpose="..." are not present, the system will check if at least 1 purpose was accepted. If that is the case, the code will be activated.
You can find the IDs of all purposes in menu Purposes:
