What is Google Ads Bidding?
Before diving into specific strategies, it’s essential to understand what Google Ads bidding means. When you run an ad campaign on Google Ads, you’re essentially entering an auction. Each time someone searches for a keyword you’re targeting, Google determines which ads to show based on several factors, including:
- Your bid amount
- Ad relevance and quality score
- Expected impact of ad extensions and other ad formats
The bid tells Google how much you’re willing to pay for a given action (e.g., a click or impression). However, the highest bid doesn’t always win. Google combines your bid with your quality score to determine your Ad Rank, which decides your ad’s position and whether it appears at all.
Understanding Google Ads Bidding Strategies
Google Ads uses an auction-driven model in which advertisers compete by placing bids for ad placements. Your bid amount, combined with your ad’s Quality Score, determines your ad’s position. Selecting the right bidding strategy is crucial to ensure your ads reach the intended audience effectively.
Manual CPC (Cost-Per-Click)
Manual CPC allows advertisers to set their maximum cost-per-click for ads. This strategy offers control over bids but requires continuous monitoring and adjustments.
Enhanced CPC (ECPC)
Enhanced CPC automatically modifies your manual bids depending on the probability of a conversion. It’s a semi-automated strategy that combines manual control with Google’s automated adjustments.
Maximize Clicks
An automated strategy designed to get as many clicks as possible within your budget. Ideal for increasing website traffic.
Maximize Conversions
Automatically adjusts bids to maximize conversions within your allocated campaign budget. Suitable for advertisers focusing on increasing sales or leads.
Target CPA (Cost-Per-Acquisition)
Adjusts bids to achieve the highest number of conversions while maintaining your specified target cost per acquisition. Effective for maintaining a specific acquisition cost.
Target ROAS (Return on Ad Spend)
Bids are set to maximize conversion value while achieving an average return on ad spend. Best for advertisers focusing on revenue.
Target Impression Share
Automatically sets bids to increase your ads’ chances of appearing in the top positions. Useful for brand awareness campaigns.
CPM (Cost-Per-Thousand Impressions)
Payment is determined by the total number of impressions your ad generates. Ideal for campaigns aiming to increase visibility.
CPV (Cost-Per-View)
Primarily used for video ads, you pay when a viewer watches your video or interacts with it. Suitable for video marketing campaigns.
Categories of Google Ads Bidding Strategies
Google offers a range of bidding strategies that fall under two primary categories:
1. Manual Bidding
2. Automated Bidding
Each category has multiple strategy options, which we’ll break down in detail below.
Manual CPC Bidding
What It Is:
Manual CPC (Cost-Per-Click) bidding gives you the ability to set specific bids for each keyword or ad group, offering complete control over the maximum amount you’re willing to pay per click.
Pros:
- Full control over bids
- Useful for experienced advertisers
- Easier to test and optimize
Cons:
- Time-consuming
- No use of machine learning
- Can be inefficient without ongoing management
Best For:
- Small campaigns
- Experienced PPC managers
- Businesses testing new campaigns
Enhanced CPC (ECPC)
What It Is:
Enhanced CPC is a semi-automated bidding option. Google modifies your manual bids, either increasing or decreasing them, based on the probability of a conversion, using historical performance data and real-time signals such as device type, user location, and time of day.
Pros:
- Better performance than manual CPC
- Adjusts to user intent
- Can boost conversions without fully automated bidding
Cons:
- Less control than manual CPC
- Still requires bid input
Best For:
- Campaigns with conversion tracking
- Advertisers transitioning from manual to automated bidding
Target CPA (Cost-Per-Acquisition)
What It Is:
This automated strategy sets bids to get as many conversions as possible at your target cost per acquisition. Google leverages your campaign’s historical data and machine learning to optimize bids dynamically in real time.
Pros:
- Optimized for conversions
- Saves time
- High efficiency for lead generation
Cons:
- Requires historical conversion data (recommended: 30+ conversions in the past month)
- Can overspend during learning phase
Best For:
- Lead generation campaigns
- Businesses with strong conversion tracking
- Campaigns with stable performance history
Target ROAS (Return on Ad Spend)
What It Is:
Target ROAS bidding aims to get the highest possible conversion value (e.g., revenue) based on the return on ad spend you specify. You tell Google what your desired return is, and it adjusts bids accordingly.
Pros:
- Focuses on revenue rather than just volume
- Ideal for e-commerce
- Uses real-time signals for smarter bidding
Cons:
- Needs significant conversion data
- Can limit reach if ROAS is set too high
Best For:
- E-commerce businesses
- Retailers tracking transaction value
- Marketers focused on ROI
Maximize Conversions
What It Is:
This automated bidding strategy aims to get the most conversions possible within your daily budget. Google sets bids automatically using machine learning.
Pros:
- Simple setup
- Good for fast growth
- Effective when budget is fixed
Cons:
- May exceed your ideal CPA
- No control over individual keyword bids
Best For:
- New campaigns with limited data
- Advertisers focused purely on volume
- Short-term promotions
Maximize Conversion Value
What It Is:
This strategy tries to get the most conversion value within your budget, similar to Target ROAS but without requiring you to set a target return.
Pros:
- Focuses on value, not just number of conversions
- No need to specify ROAS
- Ideal for dynamic product pricing
Cons:
- Less predictable than target ROAS
- Budget consumption may fluctuate
Best For:
- Advertisers who care more about revenue than cost per action
- E-commerce campaigns
Maximize Clicks
What It Is:
This approach automatically adjusts bids to generate the maximum number of clicks while staying within your set budget. It’s primarily focused on traffic generation.
Pros:
- Easy to implement
- Great for brand awareness
- Good for driving site visits
Cons:
- Not optimized for conversions
- May waste spend on low-intent clicks
Best For:
- Top-of-funnel campaigns
- New websites or product launches
- Campaigns without conversion tracking
Target Impression Share
What It Is:
Target Impression Share helps you reach a specific position on the search engine results page (SERP). You can choose to target:
- Top of the page
- Absolute top of the page
- Anywhere on the page
- Google then adjusts bids to meet your visibility goals.
Pros:
- Great for brand visibility
- Control over where your ads appear
- Ideal for competitor targeting
Cons:
- Not conversion-focused
- Can be expensive
- Risk of overbidding
Best For:
- Branded keyword campaigns
- Competitive industries
- Awareness campaigns
Portfolio Bidding Strategies
Google Ads enables the creation of portfolio bidding strategies that can be applied across several campaigns or ad groups simultaneously. This provides centralized bidding management and is especially useful for large-scale advertisers managing complex accounts.
How to Choose the Best Google Ads Bidding Strategy
Now that we’ve covered the main strategies, let’s look at how to choose the best one for your specific situation.
1. Define Your Campaign Goal
Each marketing goal aligns best with specific bidding strategies. Here’s how to match them effectively:
- Website Traffic
Use: Maximize Clicks or Manual CPC
Keep in mind: high traffic doesn’t always equal conversions. Use tools like Google Analytics and Search Console to ensure quality over vanity metrics.
- Lead Generation
Use: Target CPA or Maximize Conversions
- E-commerce Sales
Use: Target ROAS or Maximize Conversion Value
- Brand Awareness
Use: Target Impression Share
- ROI Optimization
Use: Target ROAS
2. Consider Data Availability
Some strategies, like Target CPA and Target ROAS, require sufficient historical data to function effectively. If your campaign is new, start with Maximize Conversions or Maximize Clicks, then shift once data accumulates.
3. Assess Budget Constraints
If you have a fixed daily budget, automated strategies like Maximize Conversions or Maximize Clicks can help spend efficiently. For tighter budget control, Manual CPC may be a better fit.
4. Evaluate Control vs. Automation
Manual bidding gives you more control but requires time and expertise. Automated bidding saves time and leverages machine learning but offers less transparency.
5. Monitor and Optimize
No bidding strategy is “set it and forget it.” Regular performance reviews, A/B testing, and adjustments are essential. Use tools like Google Ads Experiments and bid simulators to guide decisions.
Advanced Tips for Bidding Strategy Success
- Use Smart Bidding with Conversion Tracking: Enable conversion tracking and assign proper values to conversions. This data feeds Google’s algorithms, improving bid decisions.
- Combine Bidding with Audience Targeting: Layer in audience segments (like remarketing or in-market audiences) to refine bidding even further.
- Set Bid Adjustments Smartly: For manual strategies, use bid adjustments by device, location, or time of day to optimize performance.
- Don’t Switch Too Often: Automated strategies require a learning period (typically 7–14 days). Frequent changes can reset the learning process and hurt performance.
- Test Strategies Against Each Other: Use campaign experiments or duplicate campaigns to test different strategies side by side.
Smart Bidding and Machine Learning: Under the Hood
One of the most transformative elements in Google Ads in recent years is the advancement of Smart Bidding, which refers to a subset of automated bidding strategies that use machine learning to optimize for conversions or conversion value in every auction, a concept known as “auction-time bidding.”
Smart Bidding includes strategies like:
- Target CPA
- Target ROAS
- Maximize Conversions
- Maximize Conversion Value
These strategies use contextual signals, like location, device, time of day, browser, language, and more, to predict the likelihood of a click leading to a conversion and adjust bids accordingly. The more data Google collects about how your audience interacts with your ads, the better its algorithms can make predictive decisions.
Key Benefits of Smart Bidding
- Real-Time Optimization: Adjusts bids in real-time at every auction.
- Advanced Contextual Signals: Uses a range of signals unavailable in manual bidding.
- Continuous Learning: Algorithms improve over time as more conversion data is collected.
For businesses running large-scale campaigns or juggling multiple goals, Smart Bidding can be a game changer in maximizing efficiency and scaling results.
Combining Bidding Strategies with Campaign Types
It’s also important to align your bidding strategy with the type of campaign you’re running:
- Search Campaigns: Typically use strategies like Target CPA, Maximize Conversions, or Manual CPC.
- Display Campaigns: Often benefit from Maximize Conversions or Target CPA due to lower CPCs and broader reach.
- Shopping Campaigns: Best paired with Target ROAS or Maximize Conversion Value, especially for retailers.
- Video Campaigns (YouTube): Can utilize Target CPA or Maximize Conversions for lead generation, or Target CPM for branding.
Using the right pairing ensures that each campaign type operates at peak efficiency, maximizing both budget utilization and desired outcomes. Additionally, advertisers can create shared bid strategies across campaigns through portfolio bidding, offering greater consistency and ease of management.
By taking a strategic approach to how you integrate bidding strategies with campaign structure, you set a solid foundation for scalable and sustainable success in your Google Ads account.
