What is a Filmstrip ad unit?

The filmstrip is a relatively new ad unit classified as a “rising star” by the IAB. Though it fits into a 300×600 ad unit, the total ad is five times as tall. Visitors are able to scroll through the five segments to see new messaging. Typically, advertisers build filmstrip ad units with each segment corresponding a a deeper move down the purchase funnel:

In other words, the filmstrip would progress from a generic message highlighting the brand to a specific action item (the fifth segment may correspond to feelings of loyalty, or repeat purchases).

The IAB rising stars filmstrip will load in three distinct phases

  1. Initial File Load whereby the Base Ad Component loads and a “hidden frame” of the Full Page Ad Component also loads. This hidden frame enables the rapid deployment of the Full Page Ad Component before additional files download.

  2. Subsequent User-Initiated File Load, where the “resting state” of the Full Page Ad Component loads. Importantly, this resting state is essentially one layer deep in that it presents the full experience to the viewer, but has not loaded additional files that may be called upon with further interaction.

  3. Subsequent Additional User-Initiated File Load. This includes all files that load as a result of the viewer further interacting with the Full Page Ad Component.
