Guaranteed attention changes the brief
Because the viewer cannot skip, a non-skippable ad can afford a little more structure than a skippable one: a short setup, a demonstration and a close. It is still interrupting someone who came to watch something else, so goodwill runs out faster than the clock.
The format suits a single, memorable message. Trying to fit a product tour into 15 seconds usually produces an ad that says several things and lands none.
Choosing between non-skippable and bumper
If the message fits in six seconds, a bumper is cheaper exposure. If it needs a demonstration, non-skippable gives you the time. Many campaigns run both: the non-skippable cut to explain, bumpers to remind.
