Lapsed users are your highest-intent re-engagement audience. They already know your product. Running retargeting alongside UA means you're not just finding new users — you're protecting the investment you already made in acquiring them.

Cannibalization happens when UA and retargeting run independently and compete for the same users in the same auctions. A connected system coordinates both — excluding active acquisition targets from retargeting pools and preventing either campaign from inflating the other's CPMs.

RZR measures incremental lift through PSA testing, ghost bidding, and geo holdout, isolating retargeting's impact on revenue, conversion rate, and LTV against a clean control group. RZR owns measurement end-to-end, with no external tooling dependency and no gap between what the model sees and what gets reported. The result is a clean, auditable read on what RZR media is actually driving versus organic re-engagement.

New user acquisition competes in broad, high-volume auctions. Retargeting works with a known audience — your own lapsed users — in a targeted, less contested inventory environment. The result is lower CPMs and higher conversion rates from people who already know your product.

RZR's audience intelligence identifies users showing signs of disengagement — before they churn — and factors that risk into bid value and targeting priority. Re-engaging a user who is drifting is cheaper than recovering one who has already left. The result is retargeting spend that works earlier in the drop-off curve, where conversion rates are higher and CPMs are lower.
