Placement positions value 17 means Reversed L shape

When to send it

Value 17 is the mirrored L-shaped squeezeback. On the usual reading the content shrinks toward the top left and the ad fills a band down the right side and along the bottom. It arrived in AdCOM 1.0-202607 and is sent in Video.pos with a video plcmt of 8 (Squeezeback).

Because AdCOM does not define the orientation of either L, a buyer can only rely on 16 and 17 after confirming with the seller which side each one means. The value is also confused with 15 (Bottom Right), a corner overlay that covers content rather than resizing it.

Example

{
  "imp": [
    {
      "banner": {
        "pos": 17
      }
    }
  ]
}
