1Part 1: Understanding Bidding Strategy Fundamentals
What Bidding Strategy Actually Does
At its core, bidding strategy tells Google: "This is what I want you to optimize for."
Everything else in your campaign—keywords, ads, targeting, budget—is secondary to this fundamental instruction.
How Google Uses Your Bidding Strategy
When you select "Maximize Conversion Value":
- Analyzes which users are most likely to make high-value conversions
- Determines optimal times to show ads to these users
- Calculates how many impressions each user needs before converting
- Adjusts bids in real-time based on conversion probability and value
- Learns and refines targeting based on what actually drives value
When you select "Maximize Clicks":
- Finds users most likely to click (regardless of conversion potential)
- Optimizes for maximum click volume
- Ignores whether those users actually buy or become leads
- Result: Wasted budget on "clicky" but non-converting traffic
The difference is night and day.
The AI Optimization Era
2024+: Google's AI manages bids automatically, chooses optimal placements, and refines targeting continuously. Your job is to tell the AI what to optimize FOR.
Your bidding strategy is now your primary control lever.
2Part 2: All Bidding Strategies Explained
Conversion-Based Strategies (Recommended)
Maximize Conversions
- Automatically sets bids to get the most conversions within your budget
- No target CPA required initially
- Uses machine learning to predict conversion probability
When to Use: New campaigns without conversion history, building initial data
When to Avoid: After you have enough data for target CPA, or when conversion values differ significantly
Maximize Conversion Value
- Automatically sets bids to get the highest total conversion value within your budget
- Requires conversion value tracking
- Prioritizes high-value conversions over low-value ones
- Willing to pay more for higher-value customers
When to Use: When customer values differ significantly (recommended for 95% of advertisers)
Target-Based Strategies (Add After Baseline)
Target CPA (Cost Per Acquisition)
- Sets bids to get conversions at or below your target cost
- Some conversions cost more, some less—average approaches target over time
| Scenario | What Happens |
|---|---|
| Target too aggressive ($30 when $60 is realistic) | Campaign won't spend |
| Target at current performance ($60) | Optimal - maintains efficiency |
| Target too conservative ($100) | Google lowers quality standards |
Target ROAS (Return on Ad Spend)
- Sets bids to maximize conversion value while achieving your target return
- Higher-value customers get higher bids
- Optimizes for return, not just volume
Other Bidding Strategies (Limited Use Cases)
Maximize Clicks - Usually fails because Google finds "clicky people" who don't convert
Target Impression Share - Pays for visibility regardless of conversions
Manual CPC - Outdated. Google's AI considers thousands of signals in real-time that you can't match
3Part 3: Conversions vs. Conversion Value
The Critical Choice
Most advertisers instinctively choose "Conversions" thinking more = better. This is wrong for almost all businesses.
Why "Conversions" Can Hurt You
"Conversions" treats all conversions as equal.
Lead Generation Example:
- Lead A: $1,000 service inquiry
- Lead B: $10,000 service inquiry
With "Conversions" bidding: Both = 1 conversion. Google may spend more on low-value leads.
Why "Conversion Value" Is Superior
With "Conversion Value" bidding:
- Lead A: Google sees $1,000 value
- Lead B: Google sees $10,000 value
- Google recognizes B is 10x more valuable
- Willing to bid MORE for high-value customers
- Optimizes for total revenue
Implementing Conversion Value for Lead Generation
Method 1: Service-Based Values
| Service Type | Average Value | Conversion Value |
|---|---|---|
| Basic service lead | $500 | $500 |
| Premium service lead | $2,500 | $2,500 |
| Large project lead | $10,000 | $10,000 |
Method 2: CRM Integration (Advanced)
Import offline conversions to track which leads actually close:
| Lead Type | Close Rate | Avg Deal | Value to Assign |
|---|---|---|---|
| Type A | 10% | $1,000 | $100 |
| Type B | 40% | $2,000 | $800 |
Google learns to prioritize Type B (8x more valuable).
Performance Impact
Typical improvement from switching to Conversion Value: 30-40% better ROAS

4Part 4: When to Set Target ROAS/CPA
The Critical Timing Question
Setting targets too early or too late both cause problems.
Too Early = Disaster
- You don't know what's realistic
- Unrealistic targets prevent spending
- Campaign fails before it starts
Too Late = Missed Optimization
- Google overspends without constraints
- Efficiency opportunities missed
The Minimum Waiting Period
| Business Type | Minimum Wait | Ideal Wait |
|---|---|---|
| High volume (100+ conversions/week) | 2-3 weeks | 4 weeks |
| Medium volume (10-100/week) | 4 weeks | 6-8 weeks |
| Low volume (<10/week) | 8 weeks | 10-12 weeks |
What Happens During Waiting Period
Week 1-2: Learning phase (performance unstable). Don't panic—this is normal.
Week 3-4: Performance stabilizing, patterns emerging, still some volatility.
Week 5-8: Consistent performance, reliable data. Safe to set targets.
The Stability Requirement
Don't just wait for time—wait for stability.
Unstable (Don't Set Target Yet): Monday: 500% ROAS, Wednesday: 150% ROAS, Friday: 400% ROAS
Stable (Ready for Target): Week 1: 280%, Week 2: 310%, Week 3: 295%, Week 4: 305%
5Part 5: Setting and Scaling Targets
Setting Your Initial Target
The Rule: Set your target at (or slightly below) current stable performance.
Example:
- Current Performance: 300% ROAS (stable over 4 weeks)
- Initial Target: 300% (or 280% conservative)
DO NOT:
- Set at 600% because "that's what I want" — Campaign stops spending
- Set at 150% because "let's be safe" — Google lowers quality standards
The First Adjustment Period
After setting initial target, leave it alone for 2-4 weeks.
- Week 1: Performance often dips temporarily. Don't panic—this is normal.
- Week 2-3: Performance recovers, may stabilize at or near target.
- Week 4: Assess results, decide next steps.
Scaling Targets Over Time
- Improve Campaign: Better ad creative, improved landing pages, new offers
- Result: ROAS improves from 300% to 380%
- Wait for Stability: Don't change target after 1 good day. Wait 2+ weeks.
- Raise Target to Match: Update target ROAS from 300% to 380%
- Repeat
Example Progression:
| Month | Target ROAS | Actual ROAS |
|---|---|---|
| 1 | None | 250% baseline |
| 2 | 250% | 250% stable |
| 3 | 250% | 320% improved |
| 4 | 320% | 320% stable |
| 5 | 320% | 420% improved |
| 6 | 420% | 420% stable |
68% ROAS improvement over 6 months
6Part 6: Customer Acquisition Bidding
The Hidden Feature Most Advertisers Miss
Inside bidding settings you'll find "Customer Acquisition" options that allow you to pay MORE to acquire new customers vs. existing customers.
The Remarketing Problem
Standard Bidding Logic:
- Existing customers = easier to convert
- New customers = harder to convert
- Result: Over-indexes on remarketing
Business Reality:
- Existing customers = limited pool
- Eventually tapped out
- Need new customers for growth
Option 1: Bid Higher for New Customers
- Upload customer list (email, phone) so Google knows existing customers
- Set Incremental Value
| Customer Type | Base Value | Incremental | Total Value |
|---|---|---|---|
| Existing | $40 | — | $40 |
| New | $40 | +$25 | $65 |
Result: More budget allocated to new customer acquisition.
Option 2: Bid ONLY for New Customers
Completely excludes existing customers from seeing ads.
When to Use: One-time purchase products, new customer promotions only
Trade-off: Miss remarketing opportunities. Usually "bid higher" is better than excluding entirely.
Option 3: High-Value New Customer Bidding
| Customer Type | Bid Value |
|---|---|
| Existing customer | $40 |
| New customer | $65 |
| New HIGH-VALUE customer | $95 |
Define "high-value" by spending over threshold, premium service purchase, or high-LTV demographic profile.

7Part 7: Automated Budget Rules
Why Automate Budget Management
Manual Scaling Problems:
- Time-intensive
- Reactive rather than proactive
- Inconsistent during weekends/vacations
- No automatic pullback when performance declines
The Increase Rule
Logic: IF performance meets profitability criteria THEN increase budget by percentage
| Parameter | Setting |
|---|---|
| Name | "Budget Increase 3%" |
| Condition (Lead Gen) | CPA < $30 |
| Action | Increase budget by 3% |
| Max budget | $500/day (safety) |
| Frequency | Daily, midnight |
| Data range | Last 7 days |
The Decrease Rule
Logic: IF performance drops below threshold THEN decrease budget
| Parameter | Setting |
|---|---|
| Name | "Budget Decrease 3%" |
| Condition (Lead Gen) | CPA > $40 |
| Action | Decrease budget by 3% |
| Min budget | $100/day (maintain presence) |
| Frequency | Daily, midnight |
| Data range | Last 7 days |
The Buffer Zone Concept
Create space between increase and decrease thresholds:
| CPA Range | Action |
|---|---|
| < $30 | Increase budget |
| $30-$40 | No change |
| > $40 | Decrease budget |
Why: Prevents constant micro-adjustments from minor fluctuations.
The Compounding Effect
Why 3% daily seems small but isn't:
| Timeframe | Starting | Ending | Growth |
|---|---|---|---|
| 30 days | $100/day | $242/day | +142% |
| 90 days | $100/day | $1,427/day | +1,327% |
8Part 8: Common Bidding Mistakes
Mistake 1: Changing Targets Too Frequently
Bad Behavior: Monday: Set 300%, Wednesday: Lower to 250%, Friday: Raise to 350%
Why It Kills Performance: Every change disrupts optimization. Google re-enters learning phase.
Fix: Set target → Leave 2-4 weeks → Assess → Adjust if needed
Mistake 2: Setting Unrealistic Targets
Problem: Current ROAS: 250%. Target set: 600%. Thinking: "Maybe I'll get 400%?"
Reality: Campaign stops spending. No results.
Fix: Set targets at current performance. Scale gradually.
Mistake 3: Ignoring Conversion Value Setup
Problem: Using "Conversions" when customers have vastly different values.
Fix: Implement conversion value tracking. Assign appropriate values.
Mistake 4: Optimizing for Clicks
Problem: Choosing "Maximize Clicks" because more traffic = more sales.
Reality: Google finds clicky people, not converting people.
Fix: Always optimize for conversions or conversion value.
Mistake 5: Not Using Customer Acquisition Bidding
Problem: Standard bidding over-indexes on remarketing. Growth stalls.
Fix: Enable "Bid higher for new customers." Balance remarketing with acquisition.
9Part 9: Bidding by Campaign Type
Performance Max
- Recommended: Maximize Conversion Value (if tracking value) or Maximize Conversions
- Add Target: After 4-6 weeks stable
- Customer Acquisition: Highly recommended—PMax often over-remarkets without it
Standard Search
- Recommended: Maximize Conversion Value or Maximize Conversions
- Add Target: After 3-4 weeks stable
- Avoid: Maximize Clicks, Manual CPC
Shopping Campaigns
- Recommended: Maximize Conversion Value (essential—product values vary)
- Add Target ROAS: After 4-6 weeks
Display/YouTube
- For Performance: Maximize Conversions or Conversion Value
- For Awareness: Target CPM or Maximize Clicks acceptable
