Which value defnition is commonly used in value-centric measurement strategies?

In value-centric measurement strategies, "actual value" is commonly used because it refers to the real revenue or profit generated by a conversion, providing a concrete and measurable metric for campaign performance. This contrasts with "unique value," which isn't a standard measurement term in this context. "Necessary value" and "intrinsic value" are more philosophical or qualitative concepts and don't directly quantify the financial return of an ad campaign. Focusing on actual value allows advertisers to optimize for the most profitable conversions, rather than just the highest volume.
