When I was preparing for the Google Ads Search Certification exam (which I proudly passed with a 97% score!), one question stood out because it highlighted a huge mindset shift: you shouldn’t just count conversions—you should count value.
That’s where value-based Smart Bidding comes in. In this post, I’ll break down the correct answer to this question, explain what value-based bidding really means, why the wrong options don’t work, and how you can apply it to real campaigns. Let’s dive in!
Question
What are two types of value-based Smart Bidding strategies?
- Maximize conversion value with target ROAS
- Manual CPC
- Target impression share
- Maximize conversion value
Here are two correct answers:
✅ Maximize conversion value with target ROAS
✅ Maximize conversion value
Why These Two Are Correct
1. Maximize Conversion Value
This strategy tells Google to get the most conversion value (like sales revenue) possible with your budget.
- Google uses machine learning to prioritize high-value clicks.
- Best when you don’t want to set a specific ROAS (return on ad spend) target.
- Example: If you sell items from $10 to $500, Google will optimize for the higher-value sales.
2. Maximize Conversion Value with Target ROAS
This is similar, but now you set a goal like “I want $5 back for every $1 I spend.”
- Google tries to hit that goal while bidding.
- Great for ROI-focused campaigns.
- Example: If your target ROAS is 500%, you want $5 return for every $1 ad spend.
These are Smart Bidding strategies, meaning Google adjusts bids automatically based on real-time signals (device, location, time, etc.) to get the most valuable results.
Why the Other Options Are Wrong
❌ Manual CPC
- This is not Smart Bidding.
- You manually set bids and have full control.
- No automation or value tracking is involved.
❌ Target Impression Share
- This is Smart Bidding, but it’s designed for visibility, not value.
- It focuses on how often your ad appears, not what your conversions are worth.
- Used for brand awareness or keyword dominance.

Comparison Table: Bidding Strategies Overview
Bidding Strategy | Smart Bidding | Value-Based | Goal |
---|---|---|---|
Maximize Conversion Value | ✅ Yes | ✅ Yes | Get the most value within budget |
Max. Conv. Value w/ Target ROAS | ✅ Yes | ✅ Yes | Value with a return target |
Manual CPC | ❌ No | ❌ No | Click control |
Target Impression Share | ✅ Yes | ❌ No | Maximize visibility |
Real-Life Example:
Let’s say Tina owns an online boutique. She sells handbags ranging from $40 to $300. Previously, she ran a campaign using Maximize Conversions, and got 20 sales.
But when she checked, most of those were $40 bags. Her revenue wasn’t as high as she expected.
She switches to Maximize Conversion Value, and later to Target ROAS (400%). Google now prioritizes the higher-priced handbags. Even if she gets fewer sales, her total revenue jumps by 35%.
Value-based bidding shifted her strategy from quantity to profitability.
FAQs:
Q1: What’s the difference between value-based and volume-based bidding?
Value-based = aims for more revenue.
Volume-based = aims for more conversions.
Q2: Can I use these strategies with any campaign?
Only if you have conversion tracking with value set up. E-commerce stores are a great fit.
Q3: What is a good ROAS to target?
It depends on your profit margins. Start with 300% and adjust based on performance.
Q4: Are these strategies automated?
Yes! Google uses machine learning to adjust bids in real time based on thousands of signals.
Conclusion:
Value-based Smart Bidding is the future of profitable advertising. If you care about revenue, not just leads, use:
- ✅ Maximize conversion value for growth-focused campaigns
- ✅ Target ROAS when you want efficiency and return
Stop just chasing conversions. Start chasing value.
