Conversion value rules are worth using when your Google Ads account already records trustworthy conversion values, you run value-based bidding such as Target ROAS or Maximize conversion value, and you can prove that some customers are worth more after they convert—not merely that they convert more often. If your values are static guesses, incomplete, or disconnected from revenue, fix the measurement foundation first. This article gives you a readiness scorecard, a condition ladder, and a worked example so you can decide what to adjust—and what to leave alone.
Bottom line: Use conversion value rules to express business value differences that tagging alone cannot send. Do not use them to “fix” weak conversion tracking, inflate ROAS, or override Smart Bidding’s existing conversion-rate learning with unverified multipliers.
What conversion value rules actually change
According to Google Ads Help on conversion value rules, these rules let you adjust reported conversion values based on conditions such as audience, location, and device so bidding and reporting better reflect what a conversion is worth to your business. Google notes that Smart Bidding can use the adjusted values in real time for Target ROAS and Maximize conversion value.
Google’s setup guidance states that conversion value rules can be applied to Search, Shopping, Display, Hotel, and Performance Max campaigns. Rules can add a positive amount, multiply the passed value by a factor between 0.5 and 10, or—where available—set a specific value. Each rule can include up to two different condition types, and only one rule applies to a given conversion even when multiple rules could match.
That last point matters operationally. If you create overlapping rules, Google applies precedence logic—for example, the most precise location rule, or an audience hierarchy that prefers Customer Match over broader segments. You are not stacking every matching rule on top of each other.
The critical distinction: value difference vs conversion-rate difference
Google’s own guidance includes a limitation many accounts miss. Smart Bidding already uses signals such as geography, device, and first-party audience lists when those segments convert better and the difference shows up in your reporting. In other words, if mobile users convert at half the rate of desktop users, bidding can already respond to that pattern without a value rule.
Conversion value rules become useful when the value after conversion differs in a way your conversion action does not already capture. Examples include:
-
Enterprise-segment leads that close at higher average contract value than SMB leads, while both fire the same lead conversion.
-
Regions with durable margin or lifetime-value differences that transaction revenue tags do not reflect.
-
Store-visit or store-sales valuation that needs campaign-level adjustment relative to online sales goals, as described in Google’s Smart Bidding impact guidance.
If the only evidence you have is “this segment converts more,” you usually need better bidding inputs or more conversion volume—not a value multiplier.

Interpretation:
-
0–5: Do not add value rules. Repair conversion integrity, assign non-zero values to meaningful actions, or improve offline import quality first. Google’s conversion values best practices emphasize a measurement foundation and meaningful values before advanced optimization tactics.
-
6–8: Prepare, but keep rules limited. Prefer one high-confidence condition and a conservative multiplier. If you are still choosing between Maximize conversions and value-based strategies, resolve that decision before stacking rules—see which bid strategy to use first.
-
9–12: Value rules are justified. Start with the highest-evidence condition and measure whether bidding shifts toward the intended customers without degrading lead quality or margin.
Value Rule Condition Ladder
When the scorecard clears, prioritize conditions in this order. Climb only as far as your evidence supports.
L0 — No rule
Keep default values when every conversion of an action has roughly the same business worth, or when differences already flow through dynamic transaction values. Rules add noise when they restate what tagging already reports.
L1 — Audience rules for durable customer economics
Audience conditions are typically the strongest first move for service businesses and lead-gen accounts. Google explicitly describes using value rules when some customer types are more valuable but that nuance is not already reported in the account—for example, multiplying California leads by 2 when those leads are typically worth twice as much.
Prefer first-party segments you can explain: Customer Match lists, CRM lifecycle stages, closed-won cohorts, or high-margin product purchasers. Avoid inventing multipliers for broad affinity segments you cannot validate offline.
L2 — Location rules for margin, serviceability, or LTV
Location rules fit when geography changes contribution margin, fulfillment cost, close rate value, or average order economics in a stable way. Use the most precise geo that matches your evidence. Google applies the most precise matching location rule when overlapping rules exist, so a California rule can override a United States rule for the same conversion.
Do not create location multipliers solely because one region currently shows a better conversion rate. That is often already visible to Smart Bidding.
L3 — Device rules only with proven value—not convenience
Device rules are the easiest to misuse. Mobile may convert less often because of form friction, but that does not automatically mean a mobile lead is worth less once submitted. Adjust device values only when post-conversion economics differ—for example, if mobile leads consistently result in lower package size after sales review, and you can show that pattern outside the ad platform.
L4 — Campaign-level or store-specific valuation
Campaign-level rules can isolate adjustments so one campaign does not rewrite value definitions for the whole account. Google notes that campaign-level rules do not affect other campaigns’ bidding and reporting, with a limited exception for portfolio bid strategies. This level is useful for store-visit or store-sales valuation that should differ by campaign goal, or for a test campaign where you want a controlled rule set.
ADD vs MULTIPLY: choosing the adjustment type
|
Adjustment |
Best when |
Primary tradeoff |
|
Multiply (0.5–10) |
Relative value scales with the base value—for example, high-LTV audiences consistently worth about 1.5x average |
Magnifies both good and bad base values; poor base values become worse at scale |
|
Add (positive amount) |
You need a fixed uplift on top of an existing value—for example, a known incremental profit bonus for a segment |
Can overpower small base values and understate differences on large ones |
|
Set (where available) |
You need a specific absolute value for a tightly scoped case such as certain store conversion setups |
Availability and eligibility constraints are stricter; confirm in-account options before planning around it |
For most first implementations, multiply is clearer because it expresses relative business value. Start conservative—1.2x to 2x—unless offline data supports a larger gap. Aggressive multipliers can make Target ROAS look healthier while steering spend toward a narrow slice of inventory.
Worked example: B2B lead account with one static lead value
This is a hypothetical example, not an Oasbit client case.
A professional services firm assigns every qualified form lead a static value of $80 because average contribution from closed deals historically supports that figure. After CRM review, the team finds:
-
Leads matching a Customer Match list of mid-market accounts close at roughly 1.8x the value of other leads.
-
Mobile and desktop leads convert at different rates, but closed deal size is similar once a lead is accepted by sales.
-
One province shows higher close rates, but average deal value is not meaningfully different.
Scorecard result: 10/12. Condition ladder choice: L1 audience multiply at 1.8 for the mid-market Customer Match list. No device rule. No location rule yet.
Why this is better than optimizing only for form submits: the account already chose a primary conversion carefully, but still treated unequal customers as equal. If the firm is still debating whether form submit or qualified lead should be primary, solve that first using a conversion-trust process such as the one in form submit versus qualified lead. Value rules refine value after the conversion definition is trustworthy; they do not replace that decision.
Implementation sequence
-
Confirm primary conversion actions and whether values are static, dynamic, or CRM-imported.
-
Complete the readiness scorecard. Stop if you score 0–5.
-
Document the offline evidence for one value gap in one sentence: segment, value difference, time window, and sample size.
-
Choose account-level versus campaign-level attachment. Prefer campaign-level for tests when you need isolation.
-
Create one primary condition and one adjustment. Keep a secondary condition only when both conditions are required to define the valuable customer.
-
Remember Google’s consistency rule: once you choose primary and optional secondary condition types, subsequent rules must use the same condition types. Plan the condition schema before creating a pile of one-off rules.
-
After launch, use Google’s value-rule reporting segments—original conversion value with and without rules applied, plus the net adjustment—to verify the rule behaves as intended. Google documents this under conversion value rules reporting.
-
Revisit multipliers on a fixed cadence. If CRM evidence changes, update or remove the rule. Google states that when you remove a rule, Target ROAS and Maximize conversion value resume optimizing to your current definition of value.
Common failure patterns
-
Using rules to hide bad measurement. A multiplier cannot repair duplicate tags, missing enhanced conversions, or an unqualified form-submit primary.
-
Treating conversion-rate gaps as value gaps. If mobile converts less often, fix landing experience or accept Smart Bidding’s existing response before inventing a device value penalty.
-
Over-multiplying to force a ROAS target. Adjusted conversion value changes both optimization and reporting. Higher reported value is not the same as higher profit.
-
Creating incompatible condition schemas. Because all value rules must share the same primary/secondary condition types, an early device-first schema can block a better audience-first design later unless you rebuild the rule set.
-
Ignoring portfolio side effects. Campaign-level rules are mostly isolated, but Google notes portfolio bid strategies can create small cross-campaign effects.
When this advice does not apply
If you are still counting conversions without meaningful values, prioritize value definition over value rules. If every sale already sends accurate order value and your customer economics do not vary by audience, location, or device in a durable way, stay at L0. Travel itinerary value rules are a specialized case for Hotel and Performance Max campaigns with Travel goals and are outside the scope of most local service and B2B accounts.
Also remember policy limits: Google notes that some value-rule conditions may be unavailable for advertisers related to housing, employment, or credit.
