Bidding strategies are how you tell Google how to spend your budget to achieve your campaign goals. Choosing the right bidding strategy can mean the difference between a profitable campaign and one that wastes money.
Google Ads offers a range of bidding strategies โ from manual control where you set each bid, to fully automated "smart bidding" strategies that use machine learning to optimize for conversions.
Types of Bidding Strategies
Google Ads bidding strategies fall into three main categories:
- Manual Bidding: You set bids yourself (most control, most work)
- Automated Bidding: Google sets bids to maximize clicks or impressions (less control, less work)
- Smart Bidding: Google uses machine learning to optimize for conversions (least control, most advanced)
Manual Bidding Strategies
You manually set your maximum cost-per-click bid for each keyword. Google won't automatically adjust your bids โ you have full control over how much you're willing to pay per click.
You set the base bid, and Google automatically increases or decreases your bid in real-time based on the likelihood of conversion. It's a hybrid โ part manual, part automated.
Automated Bidding Strategies
Google sets your bids to get as many clicks as possible within your budget. It's a great starting point for new campaigns when you don't have conversion data yet.
Google sets your bids to get as many impressions as possible within your budget. This is primarily for brand awareness campaigns where visibility is more important than clicks or conversions.
Google automatically sets bids to get the most conversions within your budget. This strategy requires conversion tracking to be set up and some historical conversion data to work well.
Similar to Maximize Conversions, but this strategy focuses on getting the most conversion value (revenue) rather than the most conversions. Requires conversion value to be set up.
Smart Bidding Strategies
Google uses machine learning to set bids to help you achieve your target cost-per-acquisition (CPA). You tell Google how much you want to pay per conversion, and Google optimizes bids accordingly.
Google sets bids to help you achieve your target return on ad spend (ROAS). For example, if you want to earn โน4 for every โน1 spent, you'd set a target ROAS of 400%.

How to Choose the Right Bidding Strategy
Step 1: Identify Your Campaign Goal
Your bidding strategy should match your campaign objective:
- Traffic/Visibility: Maximize Clicks or Maximize Impressions
- Lead Generation: Maximize Conversions or Target CPA
- E-commerce Sales: Maximize Conversion Value or Target ROAS
- Brand Awareness: Maximize Impressions or Target Impression Share
Step 2: Consider Your Data Availability
Different strategies require different amounts of data:
- No conversion data: Manual CPC, Maximize Clicks
- Some conversion data (1-30 conversions): Maximize Conversions, Enhanced CPC
- 30+ conversions (past 30 days): Target CPA
- 50+ conversions (past 30 days): Target ROAS
Step 3: Consider Your Budget and Risk Tolerance
- Limited budget: Manual CPC gives you the most control
- Moderate budget: Maximize Conversions or Target CPA
- Large budget: Any strategy, but Smart Bidding works best with large budgets
- Low risk tolerance: Start with manual strategies, transition to automated later

- Setting unrealistic targets โ Target CPA too low or ROAS too high
- Not setting up conversion tracking โ Automated strategies require conversion data
- Ignoring seasonality โ Adjust strategies for seasonal fluctuations
