When it comes to online advertising, few platforms are as powerful as Google Ads. With billions of daily searches, it’s a goldmine for businesses looking to reach targeted audiences. But running a successful campaign isn’t just about choosing the right keywords or crafting compelling ad copy—it’s also about selecting the right bidding strategy. Choosing the wrong bidding approach can waste your budget and hinder performance, while the right one can optimize your ROI and boost conversions.
In this guide, we’ll break down how to choose the right Google Ads bidding strategy for your goals, budget, and campaign type.
What Is a Google Ads Bidding Strategy?
Before diving into which bidding strategy is right for you, let’s clarify what a bidding strategy is in the context of Google Ads. When you run a Google Ads campaign, you’re competing with other advertisers to have your ad shown. Google uses an auction system to determine whose ad appears, when, and where.
Your bidding strategy determines how you pay for those ad placements. Some strategies focus on getting the most clicks, others on conversions, impressions, or specific conversion values.
Why Your Bidding Strategy Matters in Google Ads
Picking the right bidding strategy isn’t just a technical decision—it’s a strategic one. Your choice impacts:
- How efficiently you use your budget
- Whether your campaign aligns with your business goals
- How much manual work you’ll need to do
- The data Google Ads uses to optimize performance
The better your strategy matches your objectives, the better your results will be.
Common Google Ads Bidding Strategies
1. Manual CPC (Cost-Per-Click)
Best for: Beginners or campaigns with limited data
Manual CPC allows you to set maximum bids for your keywords. This strategy gives you full control over your budget, which is great for advertisers who want to micromanage spending. However, it doesn’t use smart automation, so it may lack the optimization features that come with more advanced strategies.
2. Enhanced CPC (ECPC)
Best for: Transitional phase between manual and automated bidding
This is a semi-automated strategy. You set the base bids, and Google adjusts them (up or down) based on the likelihood of a conversion. It’s a great step up from Manual CPC if you’re testing automation.
3. Target CPA (Cost-Per-Acquisition)
Best for: Conversion-focused campaigns
With Target CPA, you tell Google how much you’re willing to pay per conversion, and it automatically adjusts your bids to help hit that target. If your goal is to get leads or sales at a specific cost, this strategy can be highly effective—especially for advertisers with solid historical data.
4. Target ROAS (Return on Ad Spend)
Best for: eCommerce or ROI-driven campaigns
Target ROAS is ideal for advertisers who want to focus on the value of conversions rather than just the number. You set a desired return, and Google adjusts bids to meet that ROAS goal. This strategy requires accurate conversion tracking and a healthy amount of historical data.
5. Maximize Clicks
Best for: Traffic-focused campaigns
This fully automated strategy aims to get you as many clicks as possible within your budget. It’s useful when brand visibility or site traffic is the priority, but it doesn’t guarantee conversions.
6. Maximize Conversions
Best for: Campaigns with ample conversion data
Maximize Conversions uses Google’s machine learning to get you the most conversions for your budget. It’s fully automated and works well if you want to let Google take the reins to optimize performance.
7. Maximize Conversion Value
Best for: Revenue-driven goals
Instead of focusing just on the number of conversions, this strategy focuses on their value—useful for eCommerce or high-ticket services. You must assign values to your conversions to use it effectively.
8. Target Impression Share
Best for: Brand awareness campaigns
This strategy helps your ad appear in a specific percentage of eligible impressions. You can also choose where you want your ads to show (e.g., top of the page). It’s best for businesses that want to dominate specific search results or improve visibility.
How to Choose the Right Google Ads Bidding Strategy
Choosing the right strategy depends on several factors:
1. Define Your Campaign Goals
Start by asking: what do you want to achieve?
- Leads or Sales – Consider Target CPA or Maximize Conversions
- Revenue Growth – Go with Target ROAS or Maximize Conversion Value
- Brand Awareness – Choose Target Impression Share
Aligning your goals with the right Google Ads strategy is key to success.
2. Evaluate Your Budget
Different bidding strategies have different budget implications. For instance, automated strategies like Maximize Conversions may consume your budget quickly if not carefully managed. Manual CPC may be more budget-friendly for smaller campaigns.
3. Assess Your Campaign Data
If you have minimal data or are launching a new campaign, start with Manual CPC or Maximize Clicks. For campaigns with a healthy amount of conversions and click data, Target CPA or ROAS will likely offer better performance.
4. Use Google Ads Experiments
Not sure which bidding strategy is best? Use Google Ads’ built-in “Experiments” feature to A/B test different bidding approaches. This allows you to gather data before making a full switch.
Pro Tips for Bidding Smarter
- Set realistic targets – Unrealistic CPA or ROAS goals can hinder performance.
- Monitor performance frequently – Even automated strategies need human oversight.
- Combine bidding with ad scheduling and device targeting for more granular control.
Conclusion
Choosing the right bidding strategy in Google Ads isn’t one-size-fits-all. It depends on your business objectives, the data you have, and how much control you want to maintain. Whether you prefer to manually steer your campaign or let automation take the wheel, the key is aligning your strategy with clear, measurable goals.
By understanding the strengths and limitations of each Google Ads bidding strategy—and knowing when to use them—you can run more effective campaigns, stretch your budget further, and achieve better ROI.
