Two SSPs cut CPMs ~40% on one site within 48 hours. Support says 'seasonality.' What would you do next?
~30 domains, ~70M impr/week. Header bidding via a managed wrapper — What happened — one site, 48 hours:
- SSP A — RPM $0.398 → $0.239 (−40%), impressions −1.2%. Same volume, paying less.
- SSP B — RPM $0.283 → $0.171 (−40%), impressions +15%. Buying more, paying less.
The other 12 of 15 SSPs on that site held CPM within ±10%. AdX: −5.6%.
WE did the standard tech check, traffic check, all our normal. SO our only course is CONTACT Support.
We did contact Support but the standard answer is Seasonality. MY QUESTION IS ;
- General cases once Support gives ambigous answers ( is there any leverage/what do you do)
- Can you get them look in to the case more
Any tips and help will be appreciated. If something concrete suggestion, we could do a paid working session as weill.
