Automation in Google Ads has rapidly evolved, with AI-driven tools like automated ad creation, automated bidding, and Performance Max campaigns reshaping digital advertising. In fact, 80% of CMOs report that AI and GenAI are already improving automation, speed, and productivity (BCG, 2024). Additionally, 60% of marketing leaders plan to invest at least $10 million annually in AI over the next three years. This signals a clear industry shift toward automation that includes automated ad creation.
However, does full automation guarantee better results? Not always. While Google’s machine learning can analyze vast amounts of data, optimize bids in real-time, and facilitate automated ad creation, strategic manual control is still essential to maintain efficiency and profitability. So, where’s the balance? Let’s explore how to find the sweet spot between automation and manual control in 2025.
The Case for Automation: When Does It Work Best?
Google Ads’ automation tools are designed to maximize efficiency, improve targeting, and reduce the need for constant manual adjustments. Here’s where automation shines:
1. Smart Bidding for Real-Time Adjustments
Smart Bidding strategies—like Maximize Conversions, Target ROAS (tROAS), and Target CPA (tCPA)—use machine learning to adjust bids based on real-time signals (device, location, time of day, etc.). These strategies work best when there’s sufficient conversion data to guide the algorithm, but choosing the right one depends on your business model.
- E-commerce brands selling high-margin products: tROAS could be ideal since it optimizes bids based on profitability, ensuring ad spend is directed toward the highest-value transactions. We would recommend leaving 10-20% flexibility on the goal to give Google room to find folks. tROAS and tCPA are an AVERAGE, not an absolute, so we do need to give Google room to find slightly more expensive leads/sales. For example, in tROAS: Goal is 400%, we would lower it to maybe 350% to give Google the flexibility. For tCPA: Goal is $100 per lead, we would go up to $115 to give Google the flexibility.
- E-commerce brands with lower-margin, high-volume sales: Maximize Conversions can be a better option, especially if the priority is driving as many purchases as possible rather than optimizing for revenue per transaction.
- Subscription-based e-commerce: If customer lifetime value (LTV) is more important than individual purchase value, tCPA may be preferable, focusing on acquiring new customers at a sustainable cost per acquisition.
- Lead generation: If you offer a single service, tROAS can work well, as long as you’ve established a reliable average lead value. However, for businesses with multiple services or variable lead values, tROAS becomes less effective, and Maximize Conversions or tCPA (if there’s enough conversion data) would be better suited.
2. Performance Max for Multi-Channel Reach and Automated Ad Creation
Performance Max campaigns use AI to automate targeting, automated ad creation, and creative placement across Search, Display, YouTube, Gmail, and Discover.
Best for: Businesses looking to maximize visibility across multiple Google platforms with minimal manual input and leverage automated ad creation capabilities.
3. Automated Rules & Scripts for Efficiency
Automation doesn’t always mean giving up control. Automated rules and custom scripts allow advertisers to set conditions (e.g., pause underperforming ads, increase bids for top-performing keywords, or adjust budgets based on time of day).
Best for: Large accounts that need scalable solutions for bid management, budget control, and performance monitoring.
The Case for Manual Control: When Should You Take the Wheel?
Despite the advancements in AI and automated ad creation, there are still areas where manual intervention outperforms automation by ensuring more strategic decision-making and avoiding over-reliance on algorithms.
1. Granular Keyword Control for Precision Targeting
While Broad Match + Smart Bidding can capture more volume, it also risks wasting ad spend on irrelevant searches. Manual keyword control allows for:
- Exact Match targeting for high-intent queries
- Negative keyword refinement to filter out unqualified traffic
- Manual bid adjustments on high-performing terms
Best for: B2B companies, niche markets, and businesses with highly specific customer intent.
2. Manual Bidding for Cost Efficiency
Automated bidding prioritizes conversions, but sometimes at the cost of higher CPCs. Manual CPC bidding is ideal when:
- You want to control costs in competitive industries
- Your conversion data is inconsistent (e.g., seasonal businesses)
- You need to manage budgets carefully without automated overbidding
Best for: Advertisers with strict ROAS targets, new accounts with limited conversion data, and businesses that have strict CPC limits.
3. A/B Testing for Better Creative Decisions
While Performance Max campaigns automate creative testing and utilize automated ad creation, A/B testing your ads with RSA remains essential for:
- Comparing messaging variations (e.g., promotional vs. benefit-driven)
- Testing different CTAs for engagement
- Evaluating audience preferences across ad formats
- Refining automated ad creation outputs with human insights
Best for: Brands focused on high-converting copy and image testing.
Finding the Sweet Spot: The Hybrid Approach
The best Google Ads strategies in 2025 combine automated ad creation and bidding for efficiency with manual control for strategic decision-making. Here’s how to strike the right balance:
- Use Smart Bidding with Manual Safeguards – Let Google adjust bids, but use bid caps to prevent overbidding.
- Leverage Automation for Scaling, Manual Control for Refinement – Use Performance Max and automated ad creation for broad reach, but analyze search terms and use negative keywords to fine-tune performance.
- Automate Low-Level Tasks, Keep Strategic Decisions Manual – Use rules and scripts for bid adjustments, but manually review audience targeting and keyword performance.
- Blend Automated & Custom Audiences – Test Google’s suggested audiences but refine them with your own first-party data.
Automated Ad Creation or Manual Control? Looking forward
In 2025, the smartest advertisers aren’t choosing between automated ad creation and control—they’re combining both. Automation helps scale efforts, optimize bids in real-time, and streamline ad creation. Manual control ensures precision, cost efficiency, and strategic oversight.
By blending Google’s AI-powered automation with expert-led decision-making, you can get the best of both worlds. Efficient campaign management and profitable growth.
