Google's Smart Bidding algorithms are sophisticated — but they can only optimize for the conversion signal you give them. If every lead form submission is reported as equal value (₹1 each), Google's bidding system has no way to distinguish between a ₹50,000 enterprise contract inquiry and a ₹5,000 SMB signup. Google Ads conversion value rules solve this problem by dynamically adjusting the reported value of conversions based on real-world signal differences, training Smart Bidding to acquire your highest-value customers.
What Are Conversion Value Rules?
Conversion Value Rules allow you to multiply, add, or subtract a modifier from your standard conversion value based on three contextual factors:
- Audience: Assign higher values to users in specific audience segments (e.g., your existing customer list, a high-LTV lookalike, or a market segment with proven higher close rates).
- Device: Adjust values based on the device used at the time of click (Desktop, Mobile, Tablet).
- Location: Modify values based on where the user is located (by country, region, city, or radius).
These rules do not change what you report to the client or in your spreadsheets — they modify the value signal sent to Google's bidding algorithm internally, helping Smart Bidding allocate budget toward the most valuable traffic segments.
Step-by-Step Setup: Conversion Value Rules
Step 1: Access the Measurement Menu
- Log in to your Google Ads account.
- Click the Goals (formerly Conversions) icon in the left sidebar.
- Under "Conversions", click Value rules.
- Click the blue + New value rule button.
Step 2: Select Your Conversion Actions
Choose which conversion actions this rule will apply to. You can select all conversions or specific actions (e.g., only "Lead Form Submit" but not "Phone Call").
Step 3: Define Rule Conditions
Option A — Location-Based Value Rule:
- Condition: Location = Maharashtra (or Top 3 revenue-generating cities)
- Modification: Multiply value by 1.5 (50% increase)
- Rationale: Leads from Mumbai convert to closed deals at 45% vs. 30% nationally. This signals Google to bid more aggressively in Maharashtra.
Option B — Device-Based Value Rule:
- Condition: Device = Desktop
- Modification: Multiply value by 1.3 (30% increase)
- Rationale: Your analytics show desktop users have a 3x higher average deal size than mobile users, likely because enterprise decision-makers browse at work.
Option C — Audience-Based Value Rule:
- Condition: Audience = "High LTV Customer Lookalike" (uploaded first-party list)
- Modification: Multiply value by 2.0 (100% increase)
- Rationale: Users matching your best customers should receive maximum bid priority.
Step 4: Set Rule Priority
When multiple rules match (e.g., a user in Maharashtra on Desktop who matches an audience list), you must set a priority order. The highest-priority rule wins. Set the more specific conditions (audience) at higher priority than broad conditions (location).
Step 5: Apply and Monitor
After saving the rule, Google's Smart Bidding algorithms will begin incorporating value signals within 24 to 48 hours. However, it typically takes 2 to 4 weeks of data accumulation before you see measurable bid adjustments in auction insights.
Data You Need Before Configuring Value Rules
Value rules are only effective when backed by real data. Before configuring them, pull these reports from your CRM:
- Lead-to-Opportunity rate by city/region: Which geographies convert leads to qualified deals at higher rates?
- Average deal size by device: Are mobile leads consistently smaller deals?
- LTV by audience segment: What is the 12-month revenue value of customers acquired from different ad audience types?
This analysis prevents misconfigured value rules that accidentally optimize for lower-value signals.
Combining Value Rules with Target ROAS Bidding
Value rules are most powerful when used alongside Target ROAS (tROAS) bidding. With tROAS, Google doesn't simply maximize conversions — it maximizes conversion value relative to your target return. Value rules give tROAS the signal richness it needs to distinguish high-value and low-value customers within the same conversion action.
Example: Your target ROAS is 400%. Your standard lead value is ₹5,000. With a location value rule multiplying Maharashtra leads by 1.5x, leads from Maharashtra are reported to Google as ₹7,500. Google's algorithm will bid up to ₹1,875 (₹7,500 ÷ 4 ROAS) for those clicks, versus ₹1,250 for other regions.
Common Mistakes with Conversion Value Rules
- Using rules without supporting data: Applying a 2x value multiplier to a location without CRM data confirming higher conversion rates will mislead Smart Bidding and inflate spend.
- Setting the multiplier too high: Extreme multipliers (5x, 10x) can cause over-bidding and ROAS collapse. Start with 1.2x to 1.5x modifiers and incrementally adjust based on data.
- Applying rules before sufficient conversion history: Your conversion actions need at least 30 conversions in the past 30 days for Smart Bidding to function effectively. Value rules add complexity that requires even more data.
