A playable ad is a small interactive demo, often a mini game, that a user can try inside an app before deciding to install something. Liftoff, Unity and Bigo run this format.
How it's sold
You usually book it through a mobile ad network or a DSP, and four publishers list it today.
What it costs
Most publishers quote this on request, and it is commonly bought per thousand impressions or per install.
What you supply
You supply a lightweight interactive HTML5 file, usually a 15 to 30 second demo, and a store link.
Best for
It suits you if you promote a game or app and want installs from people who already tried it.
Before you buy
Ask for the file size limit, because networks often cap playable files at a few megabytes.
