Value-Based Bidding
Also known as: Value Optimization, Bid for Value
Value-based bidding optimizes ad delivery toward the highest-value conversions rather than the highest number of conversions.
What it actually means
Standard conversion optimization treats every conversion as equal — a $50 customer counts the same as a $5,000 one. Value-based bidding fixes that by passing a dollar value with each conversion event and telling the algorithm to maximize total value instead of total count. Delivery then shifts toward people who resemble your big spenders, even if they cost more to reach and there are fewer of them. It requires honest value data flowing back through the pixel, Conversions API, or offline uploads, and enough volume for the model to learn. Businesses with wide gaps between their best and worst customers gain the most; ones with uniform ticket sizes gain little.
An HVAC company selling both $99 tune-ups and $12,000 installs should bid for value — otherwise the algorithm cheerfully fills the calendar with tune-ups and calls it success.
