Original Conversion Value: Audit Google Ads Value Rules
Updated: October 2026
Original conversion value shows what a conversion was worth before Google Ads value-rule or lifecycle adjustments changed the number used in reporting and bidding. Compare original and adjusted values to audit whether rules express real business economics—or simply make platform ROAS look better.
Why this field matters
Google Ads API v25.1 introduced an original conversion value metric for biddable conversions. Google explains that standard conversion-value fields reflect modifications made by conversion value rules. Without the original baseline, an analyst can see a higher value total without knowing how much came from transactions and how much came from configured adjustments.
Value rules can be useful. They let advertisers express differences by audience, geography, device, or other supported conditions. The audit question is whether those differences are evidenced and current.
Build a value bridge
| Layer | Meaning | Validation source |
|---|---|---|
| Original value | Value before rule adjustments | Order, lead, or CRM record |
| Rule adjustment | Configured increase or decrease | Value-rule definition |
| Lifecycle adjustment | New, lapsed, or high-value customer treatment | Customer status and model |
| Adjusted value | Value supplied to reporting and bidding | Google Ads metric |
| Realized business value | Margin or qualified revenue after outcomes mature | Finance or CRM |
A monthly audit workflow
- Export original and adjusted value. Segment by campaign, conversion action, and value-rule dimension where supported.
- Calculate the adjustment share. Show how much reported value comes from rules rather than source transactions.
- Trace large differences. Identify the exact rule, audience, device, or lifecycle condition responsible.
- Reconcile source data. Compare original values with commerce, call, or CRM records using transaction or lead IDs.
- Test assumptions. Confirm that the favored segment still produces better margin, quality, or retention.
- Document changes. Record owner, rationale, effective date, expected effect, and rollback threshold.
Do not call an adjustment lift
If a $100 purchase receives a 1.5 multiplier, the platform may report $150 in conversion value for bidding purposes. The additional $50 is not new revenue. It expresses the advertiser’s belief that the conversion is more valuable. Incrementality requires a comparison that estimates what would have happened without the advertising or rule.
This distinction matters when presenting ROAS to executives. Label platform-adjusted ROAS separately from booked revenue ROAS and contribution-margin return.
Use discrepancies diagnostically
A large gap may be intentional, but it can also reveal stale audience logic, overlapping rules, incorrect customer status, static lead values, or a value upload problem. Review both rules and raw events before changing bids.

Frequently asked questions
Does original conversion value ignore all adjustments?
Google describes it as the value before conversion value rules or lifecycle-goal adjustments for biddable conversions.
Should adjusted value match finance revenue?
Not necessarily. It can represent strategic value for bidding. Keep the finance baseline visible beside it.
What should trigger a rule review?
A large or growing adjustment share, worsening downstream quality, stale assumptions, or unexplained divergence from booked results.
