Endemic Offers

18 min

Who is this for: Partners who want to monetize their own ad inventory with first-party offers or direct partnerships, rather than relying solely on network offers.

Outcome: Create and manage endemic (direct) offers that let you control creative messaging, retain 100% of revenue generated, and pay only a cost-per-click (CPC) fee to MomentScience.

Overview

Endemic offers (also known as direct offers) let you create and manage your own advertising offers in MomentScience. Instead of relying only on network offers from external advertisers, you can run offers that promote your own products or those of direct partners.

With endemic offers you can:

Keep 100% of revenue generated

Pay only a cost-per-click (CPC) fee to MomentScience

Control messaging, creatives, and targeting

Use unused inventory for your own or partner offers

Why This Matters

Direct offers solve two challenges:

Limited control with network offers: Network offers are set by external advertisers. You only receive a revenue share.

Missed revenue on unsold inventory: Without endemic offers, unused ad space generates no value.

Endemic offers provide a reliable way to monetize every impression while maintaining full control over your ad experience.

How It Works

The difference between network and endemic offers is in how revenue flows:

Network offers: You receive revenue for Network offers served.

Endemic offers: You act as the advertiser, pay a CPC fee, and keep all revenue generated.

Endemic offers are not enabled by default. Contact your account manager to enable endemic offers for your account.
