Manual CPC and Enhanced CPC
Manual CPC (Cost-Per-Click)
What It Is:
Manual CPC lets you set the maximum bid for each keyword, ad group, or placement. You decide how much you’re willing to pay when someone clicks your ad.
Key Features:
- Full control over your bids.
- You can set different bids for different keywords based on value.
- Can be used with ad schedule, device targeting, and location bid adjustments.
Example:
If you bid ₹10 for a keyword, you’ll never pay more than ₹10 for a click (though actual CPC may be lower).
Best For:
- Advertisers who want maximum control over budget and performance.
- Campaigns with a well-defined audience or niche.
- Advanced users who monitor performance closely.
Enhanced CPC (ECPC)
What It Is:
Enhanced CPC is a semi-automated version of Manual CPC. Google adjusts your manual bids in real time to help maximize conversions.
How It Works:
- If a click is more likely to convert, Google may raise your bid (up to 30%).
- If a click is less likely to convert, Google may lower your bid to save money.
- Still uses your manual base bid, but adds smart optimization.
Example:
- You set a manual bid of ₹10.
- If Google thinks the click has a high chance of converting, it might raise the bid to ₹13.
- If low-converting, it might reduce it to ₹7.
Best For:
- Campaigns that need conversion-focused bidding but still want some control.
- Businesses transitioning from Manual to automated strategies like Maximize Conversions or Target CPA.
- Situations where historical data is limited but conversion tracking is set up.
Comparison Summary:
| Feature | Manual CPC | Enhanced CPC (ECPC) |
|---|---|---|
| Bid Control | Full control | Partial control (Google adjusts bids) |
| Automation Level | Low | Semi-automated |
| Optimized for | Clicks | Conversions |
| Best For | Skilled PPC managers | Balanced control + smart bidding |
| Learning Required | High | Medium |
Final Tip:
Start with Manual CPC if you want to test keyword performance and audience behavior. Switch to ECPC once you’ve got conversion tracking in place and want Google to help optimize bids more efficiently.
Maximize Conversions
Maximize Conversions is a fully automated bidding strategy where Google Ads automatically sets your bids during the auction to help you get the most conversions possible within your budget.
How It Works
- Google uses machine learning and historical data to adjust your bids in real-time.
- It analyzes user intent, device, location, time of day, audience signals, and more.
- Bids are increased when a conversion is likely and decreased when it’s not.
Key Features:
- No manual bidding required — Google handles all adjustments.
- Focuses on volume of conversions, not cost efficiency.
- Works best when you have conversion tracking properly set up.
Example:
- Let’s say your daily budget is ₹1,000:
- Google will try to generate as many leads, sales, or form fills as possible within that ₹1,000, even if some cost more than others.
- If 1 lead costs ₹200 and another costs ₹500, Google might still go for both if it helps increase your total conversions.
Best For:
- New advertisers who want to simplify bidding and let Google optimize.
- Campaigns where the primary goal is getting more conversions, regardless of cost per conversion.
- Situations with a limited time frame or when testing new landing pages or offers.
Things to Watch Out For
- May increase CPA (cost per acquisition) since it doesn’t aim for efficiency.
- Works best when you already have a decent amount of conversion data (Google recommends at least 15-30 conversions in the last 30 days).
- If your budget is too low, Google may struggle to optimize.
How to Set It Up
- In Google Ads, go to your campaign settings.
- Under Bidding, choose Maximize Conversions.
- Ensure conversion tracking is enabled and properly configured.
- Set your daily budget (Google will not exceed it).
- Save and launch your campaign.
Pro Tip:
If you want more control over cost per conversion, consider switching to Target CPA once you have enough conversion data. Maximize Conversions is a great way to start and let Google learn what works.
Target CPA & Target ROAS
1. Target CPA (Cost Per Acquisition)
What It Is:
Target CPA automatically sets your bids to help you get as many conversions as possible at or below your desired cost per acquisition (lead, sale, signup, etc.).
How It Works:
- You tell Google how much you’re willing to pay per conversion (e.g., ₹200 per lead).
- Google adjusts your bids in real time using AI, analyzing signals like device, location, time of day, search intent, etc.
- If it predicts a user is likely to convert at a lower cost, it may bid more aggressively.
Example:
- You set a Target CPA of ₹300.
- Google optimizes your bids to get conversions around that value.
- Some may cost ₹250, some ₹320, but on average, the CPA will aim to stay near ₹300.
Best For:
- Advertisers focused on lead generation or sign-ups.
- Campaigns with at least 15–30 conversions in the last 30 days (recommended).
- Businesses with clear cost-per-lead/sale benchmarks.
Pro Tips:
- Avoid setting your CPA target too low at the start. Let Google learn.
- Use conversion tracking and attribution properly.
- Monitor performance after a 1–2 week learning period.
2. Target ROAS (Return on Ad Spend)
What It Is:
Target ROAS (Return on Ad Spend) is designed for revenue-focused advertisers. It lets you set a desired return, and Google adjusts your bids to maximize conversion value rather than just the number of conversions.
How It Works:
- You set a target ROAS (e.g., 400%, meaning ₹4 in revenue for every ₹1 spent).
- Google automatically sets bids to get high-value conversions rather than just more conversions.
- Perfect for ecommerce and businesses where sales value varies.
Example:
- You sell products ranging from ₹500 to ₹5,000.
- You set a Target ROAS of 400%.
- Google bids higher for users more likely to purchase higher-priced products.
Best For:
- Ecommerce stores or any business with value-based conversions.
- Campaigns with at least 30+ conversions in the past month and assigned values.
- Advertisers who want to maximize revenue efficiently.
Pro Tips:
- Use conversion values in your tracking setup.
- Start with a realistic ROAS goal based on past performance.
- Analyze product or service profit margins before setting targets.
Target CPA vs Target ROAS – Key Differences
| Feature | Target CPA | Target ROAS |
|---|---|---|
| Goal | Maximize conversions at a set CPA | Maximize conversion value at a set ROAS |
| Focus | Quantity of conversions | Value of conversions |
| Best For | Lead generation, form fills | Ecommerce, sales-focused businesses |
| Needs Values? | No | Yes |
How to Set Up (Steps)
1. In Google Ads, go to campaign settings.
2. Under Bidding, choose:
- “Target CPA” → Set your desired cost per conversion.
- “Target ROAS” → Set your desired return percentage (e.g., 500% = 5.0).
3. Ensure conversion tracking is active and accurate.
4. Set a budget and let the strategy optimize (allow 1–2 weeks for learning).
When to use Smart Bidding
What is Smart Bidding?
Smart Bidding is a set of automated bidding strategies in Google Ads that use machine learning to optimize for conversions or conversion value in every ad auction (also known as “auction-time bidding”).
Examples of Smart Bidding Strategies:
- Maximize Conversions
- Maximize Conversion Value
- Target CPA (Cost per Acquisition)
- Target ROAS (Return on Ad Spend)
- Enhanced CPC (partially smart)
When to Use Smart Bidding
1. When You Have Conversion Tracking Set Up
- Smart Bidding relies on conversion data to make decisions.
- If you’re tracking leads, sales, sign-ups, or any meaningful action, Smart Bidding can optimize for more of those.
2. When You Want to Save Time Managing Bids
- If managing bids manually is time-consuming or overwhelming.
- Smart Bidding takes over and continuously optimizes based on performance.
3. When You Have Consistent Conversion Data
Google recommends:
- At least 15-30 conversions for Target CPA.
- At least 30-50 conversions for Target ROAS. The more data you have, the better Smart Bidding performs.
4. When You’re Running Large Campaigns
- For large accounts with many keywords or ad groups.
- Smart Bidding efficiently handles complex bid decisions in real time, much faster than a human.
5. When Your Audience & User Behavior Vary
- If users behave differently based on time, device, location, or audience.
- Smart Bidding uses real-time signals to make smart decisions for every auction.
6. When You Want to Maximize Results Within Budget
- If your main goal is to get the most conversions or revenue within a specific budget.
- Use Maximize Conversions or Maximize Conversion Value.
7. When Scaling Campaigns
- As your campaigns grow and you test new markets or products:
- Smart Bidding helps maintain performance while scaling up.
When Not to Use Smart Bidding
- You don’t have conversion tracking properly set up.
- You’re just testing early-stage keywords or creatives with no past data.
- Your goal is strictly brand awareness or traffic (try Manual CPC or Maximize Clicks instead).
- You need tight control over every individual bid (use Manual CPC).
Good Transition Plan
- Start with Manual CPC to test and gather data.
- Once you have reliable conversion data, shift to Enhanced CPC.
- Then upgrade to Target CPA or Target ROAS based on your goals.
Pro Tips for Using Smart Bidding Effectively
- Give it time: Let Google’s algorithm learn (typically 1–2 weeks).
- Don’t make frequent changes—avoid disrupting the learning phase.
- Monitor metrics like CPA, ROAS, conversion rate, and impression share to evaluate performance.
