Each Conversion Boost℠: Quality Tier℠ and Pops target has a customizable Estimated CPV (eCPV), which determines how much you'll pay per impression on Pops.

Conversion Boost allows you to place custom bids based on how likely it is that an impression will lead to a conversion. Conversion Boost contains three Quality Tiers, and each tier has a slider that you can adjust to customize your eCPV bid for that tier's traffic.

Below each tier, you'll see an eCPV amount that tells you the most you'll pay, by default, per impression from that tier. Learn more about Conversion Boost: Quality Tiers.

Targets with custom bids have their own eCPVs. When you customize a target's bid, the amount you pay per impression will update according to your Quality Tier slider positions.

On the Targets tab within a Pops campaign, you'll see an eCPV range listed per target. This shows you how much you'll spend, at most, per impression for this target across all Quality Tiers.

NOTE: Because Proxy Bids ensure you only pay slightly more than the next highest eligible bid, the amount you pay per impression is likely to be lower than your eCPVs.
