How Target CPA Works
Google changes bids auction by auction based on predicted conversion likelihood. Individual conversions can cost more or less than the target; the strategy aims toward the target as an average over time. Google updated the visible strategy labels in 2026, but the underlying behavior remains the same.
A Simple Example
With a $75 Target CPA, one lead might cost $40 and another $110 while the campaign works toward an average near $75.
Why Target CPA Matters
Target CPA provides a clear efficiency control for campaigns where conversions have reasonably similar business value.
Common Misreading
A target that is much stricter than recent performance can restrict traffic and conversion volume. The target is a steering input, not a guaranteed price for every acquisition.
