What is OEM & Preload Traffic?

OEM and preload traffic is installs and first opens of apps preloaded by device makers (OEM) or carriers: Samsung, Xiaomi, carrier bloatware, out-of-box apps. The user opens a preinstalled app → monetization via ads or affiliate offers inside.

Channel

B2B deals with OEM/MDM; not self-serve for typical arbitrage buyers. High CPI, volume capped by contract. Some traffic is incentivized if the install is not organic.

Quality

D1/D7 retention is critical — preload without engagement leads to uninstalls. Fraud: fake activations. MMP validation is mandatory.

Vs. in-app ads

Preload is a distribution channel; in-app ads monetize inventory inside any app.
