Example: One ad tag, one ad unit in GAM, but can be filled with a 970x250, 728x90, and 320x50.
Yes, the Jeeng integration with GAM does support multiple ad sizes in the same ad unit. Currently this is available for GAM campaigns only, while the Jeeng network will fill with one of the sizes.
Good options include:
- 970x250, 728x90, 320x50 in a single tag
- 300x250 and 300x600 in a single tag
