In 2025, Google Ads introduced new bidding strategies designed to help advertisers optimize their Return on Ad Spend (ROAS) and drive better campaign performance. With the increasing complexity of digital advertising, these advanced bidding options leverage machine learning and AI-driven insights to automate and refine bid management. This blog explores the key bidding strategies, their benefits, and how digital marketers can use them to maximize ROAS.
1. What Are Google Ads Bidding Strategies?
Google Ads bidding strategies determine how much you are willing to pay per click, impression, or conversion. The goal is to optimize ad placements, control spending, and improve overall campaign efficiency.
In 2025, Google introduced new AI-powered strategies that offer more precise targeting, real-time bid adjustments, and better budget utilization. These strategies are designed to improve:
- Conversion Rates: By focusing on high-intent users.
- Cost Efficiency: Through smarter bid automation.
- Campaign Scalability: By adjusting bids based on performance trends.
2. Key New Bidding Strategies in 2025
A. Value-Based Bidding
Google Ads has introduced value-based bidding to help advertisers focus on maximizing revenue rather than just conversions.
- How It Works: Instead of bidding for a fixed conversion value, you can now assign dynamic values based on customer lifetime value (CLV), purchase amount, or profitability.
- Use Cases:
- E-commerce brands can prioritize high-value customers.
- Subscription-based services can bid higher for long-term subscribers.
- Benefits:
- Increased ROAS by focusing on high-value conversions.
- Better budget allocation for profitable audience segments.
B. Target ROAS with Real-Time Signals
Google has enhanced its Target ROAS bidding strategy by incorporating real-time signals.
- How It Works: The system uses AI to analyze user behavior, location, device, and past interactions in real-time to adjust bids.
- Use Cases:
- Retailers can boost bids for users with higher purchase intent.
- Travel businesses can target users actively searching for flights or hotels.
- Benefits:
- Improved ROAS by bidding more effectively based on real-time signals.
- Reduced ad spend waste on low-converting audiences.
C. Enhanced Maximize Conversions
The Maximize Conversions strategy has been upgraded with predictive AI models. It now considers more granular signals, such as user intent and search patterns, to automatically adjust bids.
- How It Works: Google’s AI dynamically sets bids to maximize the total number of conversions within your budget.
- Use Cases:
- Lead generation campaigns aiming to drive more form submissions.
- E-commerce sites targeting checkout completions.
- Benefits:
- Increased conversion volume without manual bid adjustments.
- Smarter budget utilization through automated optimizations.
D. Smart Bidding with Seasonality Adjustments
Google now offers Smart Bidding with seasonality adjustments, allowing advertisers to prepare for expected changes in conversion rates.
- How It Works: You can set bid modifiers during specific time frames, such as sales events or seasonal peaks, to boost bids temporarily.
- Use Cases:
- E-commerce retailers running holiday promotions.
- Travel agencies bidding higher during peak travel seasons.
- Benefits:
- Higher visibility during seasonal spikes.
- Better ROAS during short-term events.

If your business has varying customer values, use value-based bidding to prioritize high-profit segments.
- Example: An e-commerce site can assign higher bid values to users purchasing premium products.
B. Set ROAS Targets Based on Profit Margins
For campaigns focused on profitability, use Target ROAS with defined profit margin goals.

B. Limited Control Over Individual Bids
With automated bidding, you have less control over individual bid adjustments.
- Solution: Use campaign-level ROAS targets and performance insights to manage overall profitability.

Inaccurate conversion tracking can lead to ineffective bid optimizations.
- Solution: Regularly audit your conversion tracking setup to ensure accurate data collection.
