Redirect preferred as <iFrame>. When providing third-party advertising media, please ensure that it supports HTTPS. HTML5 is also possible following prior agreement.
- Redirect/Tracking requirements
IAB TCF:
All URL-based components of an advertising medium (e.g. redirect, pixel tracker) must contain the IAB macro gdpr_consent=${GDPR_CONSENT_XXX} to process the TC string, where XXX is the numerical vendor ID according to the global vendor list of the IAB.
Example:
Pixeltracker without IAB macro of a vendor with ID 123:
http://vendor-a.com/key1=val1&key2=val2
This Pixeltracker incl. IAB macro:
http://vendor-a.com/key1=val1&key2=val2&gdpr_consent=${GDPR_CONSENT_123}More Information: here
- Default format
320 x 480 px (640 x 960 px Retina resolution).
When using the Retina resolution in HTML5/Redirects, the output size always has to be 320 x 480 px.
- Motifs
The standard is 1 motif per booked placement. In the case of a motif split, a limit of max. 3 motifs per placement is to be taken into account, and 1 motif change per week in the case of physical delivery.
Ad Alliance reserves the right to approve each motif on a case-by-case basis. Ads that elicit too strong a reaction or too heavily impair the use of the websites may be rejected.
As of 5 items per campaign, a maximum of 1 motif/day/redirect per item is possible. That is why we recommend delivering several motifs behind one redirect.
- Lead time
3 working days
- Delivery
- Notes
The length of the animation must not exceed 7 seconds.
The close button is set by the marketer and therefore does not have to be included in the delivered creative.
- "Advertisement" label
"-w-" in one of the 4 corners
- AI labelling
Currently, we do not have any additional technical or formal requirements regarding the type of labelling to be used when advertising materials are submitted to us.
As a general rule, the client or the commissioning agency is responsible for the legal review and for ensuring compliance with any applicable labelling or transparency requirements for submitted advertising materials (see also Section A.7 of the Ad Alliance General Terms and Conditions).
