2nd Quarter 2020

April 1st 2020: technical specifications with new interface and content optimisation

There are numerous changes to the technical specifications of iq digital which are briefly outlined below.

Uniform structure: to ensure improved structuring of ad format specifications, each page comprises the following elements:

  1. Technical data – (format sizes, file size …)
  2. Provision of formats – (physical or 3rd-party)
  3. [OPTIONAL]: specific information for the called ad format
  4. Basic requirement – basic specifications for all ad formats at a glance


Initial subload: when the LEAN guidelines and the New Ad Portfolio were published by the IAB Tech Lab, the concept of initial load/subload was introduced in the technical specifications of iq digital to replace the previous “polite download”. This concept provides for the division of the total file size into an initial and a subsequently loaded part. Loading of the advertising content is initially limited to the initial part in order to optimise the loading times of the webpages and to boost user awareness. See File sizes and loading phases for more information..

Synchronisation – technical specifications

  1. No longer any differentiation between billboard rotation and fixed position (there is now only one ad format page)
  2. Page-specific format allocation for wide rectangle no longer applicable (there is now only one format size)
  3. Expandable features have been removed (removed from the portfolio last year due to the LEAN guidelines)
  4. Transformed ad formats of the type “stationary” (10:1 – 1:1) have been renamed “IAB New Ad Portfolio (static-size)” in preparation for future flex ad types of these ad formats.
