VAST Video Placement Types and Tracking Options
All the video placement types we can see in VAST video bid requests are in the table below.
| Value | Placement type | What it means |
|---|---|---|
| 1 | In-Stream | Plays before, during or after the video content the viewer chose to watch (pre-roll, mid-roll, post-roll). |
| 2 | In-Banner | Plays inside a display banner slot, so it needs display ad space on the page. |
| 3 | In-Article | Starts playing between paragraphs of an article, as a standalone message. |
| 4 | In-Feed | Appears inside a content, social or product feed. |
| 5 | Interstitial / Slider / Floating | Stays on screen while shown, covering all or part of it. A full-screen interstitial is marked separately in the bid request (imp.instl). |
