Placement positions value 8 means Partial Screen
The ad takes part of the screen while the program or page content stays visible next to or under it.
When to send it
Value 8 was added in AdCOM 1.0-202607 with the CTV ad format work. Use it when the ad occupies a portion of the screen, the content stays on screen, and none of the more specific layouts (9 to 17) fits. On OpenRTB 2.6 it is sent in Video.pos or Banner.pos, usually alongside a video plcmt of 7 (Overlay) or 8 (Squeezeback).
Buyers use the value to choose creatives designed for a reduced canvas instead of full-screen assets that would be cropped or shrunk. It is confused with 7 (Fullscreen) and with the corner and shape values. If you know the exact layout, send the specific value and keep 8 as the fallback. Buyers built against the older 0 to 7 list may not recognize it.
