The lower your fill rate, the more Epom saves.
Pop, push and remnant traffic fills far below display, so paying per impression keeps your bill tied to the ads that actually show.

The Questions That Come Up on Every Call
01 Is Epom a good Adserver.online alternative?
Yes, if your fill rate is low — pop, push and remnant traffic — because Epom bills only impressions served. You also get support, retargeting and manager logins from the first plan. A display publisher with high fill pays less on Adserver.online.
03 Does Epom serve push and in-page notification ads?
Epom serves in-page push styled as an OS notification, alongside tab-under, tab-up and popunder. Subscription-based web push is not part of the platform.
05 Which verticals does Epom accept?
Adult, gambling, crypto, dating and nutra all run. The platform sets no vertical restrictions; creative moderation is yours to switch on.
02 Is Adserver.online cheaper?
Per request, yes: its plans start at $29 for 1M ad requests. Per impression, it depends on your fill rate. At 15% fill, 50M requests means its $599 plan there and Epom’s $250 plan.
04 Does Epom accept XML or JSON feeds?
No. Epom connects demand over OpenRTB and Prebid, so feed partners need to move to OpenRTB.
06 How hard is it to switch?
Mostly a tag swap. Rebuild your placements and campaigns in Epom, run one site through both for a couple of weeks, then move the rest.
