The poster format of online advertising with outstanding advertising impact thanks to 100% visibility. The ad also moves when the user scrolls the page and therefore acts like a poster on the right-hand side, and this opens up a high level of creative freedom. The scroll depth can be important for the creation of the advertising. This is provided by iq digital as a postMessage named 'scroll_message_sitebar' and can be queried using the value data.scrollPercent, as in the example below (section scroll depth).

Special information for this ad format

Scroll depth

The scroll depth can be important for the creation of the advertising. This is provided by iq digital as a postMessage named 'scroll_message_sitebar' and can be queried using the value data.scrollPercent. The postMessage look like this {event_id: 'scroll_message_sitebar', scrollPercent: 54} . ScrollPercent is an integer value.

const handler = (event) => {
	window.addEventListener('message', function (event) {
		if(, 'event_id') && === "scroll_message_sitebar") {
            // TO SOMETHING HERE

  window.addEventListener('message', handler);

Tablet Fallbackbanner

It is also pointed out that advertising formats on outer surfaces on tablets can lead to misrepresentations. It is therefore recommended for fixed placements to also deliver a billboard, which is used as a fallback.

Display area

iq digital automatically sets the width and height of the advertising space or the surrounding top iFrame element of the creation to suit the area of the available display space next to the content and ensures positioning in the permanently visible area of the browser.


The following applies: the creative agency is responsible for the ad motif representation within the display frames with different sizes of the ad space. This means that with delivery of a:

physical HTML5 zip file or 3rd-party iFrame, the creative agency provides a responsive ad with a ready functionality that automatically downsizes, upsizes, positions or replaces the content of the creation (HTML, CSS, texts, images, other …) to suit the provided display area (which may be larger or smaller than the initially optimised format) and that ensures full and optimum presentation. Please also make sure the click button/area is of a corresponding size.

Please always note the following:


All elements of a campaign and the creative must be HTTPS-compatible (see SSL conformity (HTTPS)).

Calculation of file size and loading phases

The max. size of the specified ad component and its allocation to the loading phase in question (initial load/subload) refers to the value after the files (HTML, CSS, script, libraries, graphics and other assets) have been gzip-compressed (see File sizes and loading phases).


HTML, scripts and all components that form part of the ad presentation must remain in the ad iFrame tag of the marketer or the 3rd-party host and may not be positioned outside this tag. This means that no DOM insertion of ad components in the top window of the serving website is permitted.

Sound and animation

Ad creations must always be supplied with deactivated sound. Activation is only permitted based on deliberate interaction on the part of the user, and sound volume must comply with the loudness standard EBU R 128.
Animations should not exceed 30 seconds in total, looping is only permit within this time frame. It is important to make sure that these do not unnecessarily burden the processor of the computer.

In addition, since August 2020, the Google Chrome browser installs limits for ad resources (CPU load / loaded MBs) and will remove ads from the page that exceed these limits - "Heavy Ad Intervention".

An ad is considered heavy in terms of CPU load (defined by Chrome Browser),

  1. if the user has not previously interacted with it
  2. the ad scripting uses the main thread of the browser longer than 15 seconds in a 30-second window or in total longer than 60 seconds.

The technical specifications of iq digital for the provision of advertising material shows, that the current product range is well positioned with regard to the possible exceeding of the limit for the Chrome browser. Please adhere to the specifications already upon delivery of the material in order to avoid corrections. iq digital accepts no responsibility for advertisements unloaded by the browser.

Video content

If this ad is not a recognised instream or outstream ad, it is only possible to implement video content with processing as a 3rd-party redirect (if approved) in the host-initiated subload (max. 4 MB in the stationary Web and max 2 MB in the mobile Web); max. length 15 - 30 seconds, frame rate: 25 images per second (FPS). Due to the high bandwidth usage of video-content, videos on smartphones are served with broadband targeting. iq digital reserves its right to add broadband targeting on other platforms as well if it is necessary.

Click tracking

The ad server of the marketer can only correctly measure the clicks on an ad if a click-sensitive surface to forward the user to the client target site is implemented in the creative code and the insertion of ad server macros for the counting of clicks is possible. An external click command URL (3rd-party click tracking incl. target URL for forwarding to the client landing page) is also to be delivered as follows depending on how the ads are provided:

In the case of delivery of physical IMAGE files Delivery of 1 click command per ad motif; allocation incl. ad server macro as full-area click forwarding by iq digital ad server templating.
In the case of delivery of a physical HTML5 zip file Delivery of 1 click command per ad motif or multi-click area – allocation incl. ad server macro in HTML5 creative code by creative agency - see OVK standard procedure for the transfer of click tag and forwarding - HTML5 Guideline
In the case of delivery of a 3rd-party redirect See Click tracking – Delivery of 3rd-party resources

Other tracking tools

The serving of additional scripts/services for tracking/measurement of parameters other than those required for reporting on campaign performance (e.g. impression counting, click counting and coordinated ad verification) is not permitted and must be communicated and approved in advance. Please refer in particular to the requirements for compliance with data protection regulations and the ban on the creation of profiles from the utilisation behaviour of users on the websites of iq digital (General Terms and Conditions of Business). iq digital reserves the right to reject this kind of tracking.

Ad identification and labelling

In order to differentiate them from editorial content, ads in in-page positions are made recognisable by their placement in the advertising space on the page of the website in question. Ads in the mobile environment should additionally be labelled in the ad itself by means of a -w- in one corner using a high-contrast font colour with a font size of at least 9pt. If such labelling is absent, iq digital reserves the right to integrate this labelling in the ad.


iq digital reserves the right to approve each ad motif on the basis of a case-by-case decision. Ads that do not comply with the specifications, result in excessive reactance (CPU load of average user devices) or impair use and general performance of the pages must be corrected by the agency delivering the ad or can be rejected. The technical specifications of iq digital are subject to change. For this reason, technical specifications apply to the respective advertising order in the version valid at the time the advertising order is concluded.
