Conversion value explained — the monetary value attached to a conversion for value-based bidding, and why arbitrary values mislead the algorithm.

Conversion value is the amount associated with a conversion—actual revenue, margin, expected lead value or another documented economic value.
Why it matters
Value lets platforms distinguish a $20 order from a $2,000 order and a weak lead from a valuable opportunity. Bad values are worse than no values because they directly train automated bidding toward the wrong economics.
How it works across ad platforms
Platform or system
Current treatment
Google Ads
Supports fixed/dynamic conversion values and value-based bidding.
Meta
Purchase and other events can send value/currency; CAPI supports custom data.
LinkedIn
Conversion rules can use fixed, dynamic or no value under current workflow.
TikTok
Standard event parameters include value/currency for commerce actions.
Reddit
Purchase value/currency required for DPA.
Microsoft Advertising
Goals can use revenue values; custom/offline events support value fields.
Pinterest
Checkout and other events can send value/currency.
Implementation rules
Choose one economic definition.
Use source-system dynamic revenue for purchases.
Use ISO currency.
Model lead value from observed downstream rates.
Update values when the business model changes.
Avoid counting early and late stages as additive revenue unless intended.
Common mistakes
Hard-coding the same value for all orders.
Assigning arbitrary lead values to unlock bidding.
