Open Bidding double-dips your own demand

Open Bidding double-dips your own demand

Watching: when an SSP runs both as a GAM Open Bidding partner and a header bidding wrapper, the same DSP can reach your impression through two paths at different fee takes. The cheaper path should win — but auction timing and the dynamic allocation gate don't always let it.

— Same demand, two doors, two fee stacks
— OB's server-side revenue share can quietly beat a better client-side bid on timing

Impact: pick one path per SSP per demand source, or you're paying twice to reach one buyer. (sourced)
