Smart Bidding has transformed Google Ads campaigns by using advanced machine learning to optimise bids in real time. It allows advertisers to achieve their business goals by targeting the right audience at the right time, minimising manual effort, and improving campaign performance. This article delves into how Smart Bidding works, its bidding strategies, when to use it, and how to maximise its potential while avoiding common pitfalls.
What Is Smart Bidding?
Smart Bidding is a set of automated bidding strategies designed to help advertisers achieve specific conversion goals in Google Ads. Unlike manual bidding, Smart Bidding algorithms factor in a wide range of signals—such as device type, user location, time of day, and user intent—to make auction-time bidding decisions. These strategies utilise machine learning to analyse millions of signals and combinations of signals in real time.
Key Smart Bidding Strategies
- Target Cost Per Acquisition (CPA) This strategy focuses on achieving conversions at a set cost per acquisition. For example, a legal firm aiming for consultation bookings at £50 per lead could use Target CPA to ensure consistent costs while targeting high-value users.
- Target Return on Ad Spend (ROAS) Ideal for advertisers seeking to maximise revenue. This strategy ensures campaigns prioritise conversions with higher conversion values, making it a strong choice for e-commerce businesses.
- Maximise Conversions Designed to increase conversion volume within a given budget, this strategy is suitable for campaigns prioritising lead generation or awareness.
- Maximise Conversion Value Focuses on generating the highest revenue possible, prioritising actions with high conversion values. It is particularly effective for businesses selling premium products or services.
When Should You Use Smart Bidding?
The suitability of a Smart Bidding strategy depends on your campaign objectives, historical performance, and the data available. Here are some scenarios where each strategy shines:
Target CPA
- Best for campaigns with a clear cost per action target, such as lead generation.
- Works well when the volume of conversions aligns with your CPA goal.
Target ROAS
- Ideal for businesses prioritising profitability over volume.
- For instance, a retailer might focus on high-margin products by setting a ROAS target based on historical conversion value.
Maximise Conversions
- Effective for awareness campaigns or when increasing conversion volume is the primary goal.
- Suitable for fixed-budget campaigns that aim to reach a wider audience.
Maximise Conversion Value
- Useful for businesses dealing with varied transaction sizes or high-value products.
- Luxury retailers, for example, can use this strategy to focus on high-value conversions.
How to Set Up a Smart Bidding Campaign
Setting up Smart Bidding campaigns in Google Ads is straightforward. Follow these steps:
- Define Campaign Objectives Determine your goals, whether it’s to achieve a specific target CPA, increase conversion volume, or maximise revenue.
- Select Campaign Type Choose a campaign type that aligns with your advertising goals. Smart Bidding works across search, shopping campaigns, and video action campaigns.
- Choose a Bidding Strategy Under the “Bidding” section, select the strategy that matches your campaign objectives. For example, opt for Target ROAS for profitability-focused campaigns or Maximise Conversions for volume-based campaigns.
- Configure Parameters Set your campaign budget, audience targeting, and relevant keywords. Include negative keywords to filter out irrelevant search queries.
- Launch and Monitor Activate your campaign and track key metrics such as conversion rate and return on investment. Use tools like auction insights to understand performance.
Common Pitfalls to Avoid
Smart Bidding campaigns can underperform if certain challenges are not addressed. Here are some common pitfalls and solutions:
Insufficient Data
- Smart Bidding relies on historical conversion data. Campaigns with fewer than 20-30 conversions per month may struggle to optimise effectively.
- Solution: Start with manual bidding to gather data, then transition to automated bidding strategies.
Misaligned Goals
- Choosing the wrong strategy can lead to suboptimal results. For example, using Target CPA for campaigns focused on maximising revenue may prioritise volume over profitability.
- Solution: Align the bid strategy with your campaign goals.
Ignoring the Learning Phase
- Smart Bidding strategies require time to adjust, typically one to two weeks. Frequent changes during this period can disrupt performance.
- Solution: Avoid making major adjustments during the learning phase.
Overlooking Seasonal Trends
- Smart Bidding algorithms may not account for sudden shifts in user behaviour caused by seasonal events.
- Solution: Use seasonality adjustments for predictable demand spikes.
Underutilising Advanced Features
- Tools like bid simulators, audience layering, and portfolio bidding strategies are often overlooked.
- Solution: Explore advanced features to gain deeper insights and refine bidding processes.
Best Practices for Smart Bidding Success
To maximise the benefits of Smart Bidding, consider the following best practices:
Accurate Conversion Tracking
- Proper conversion tracking is critical for Smart Bidding performance. Ensure conversion tracking status is active and configured correctly for accurate results.
Set Realistic Targets
- Overly ambitious CPA or ROAS goals can hinder performance. Base targets on historical averages and adjust incrementally.
Leverage Audience Segments
- Use audience targeting options such as in-market audiences or remarketing lists to add context to the bidding algorithm.
Monitor Key Metrics
- Regularly review metrics like impression share, search query performance, and conversion volume to assess campaign health.
Experiment with Strategies
- Use Campaign drafts and A/B tests to compare the performance of different Smart Bidding strategies.
Tailor for Device-Specific Performance
- Analyse device-specific performance data to refine bid adjustments for mobile devices or desktops.
Advanced Optimisation Techniques
Once your campaigns achieve stability, advanced techniques can help refine performance:
Use Bid Segmentation
- Break down campaigns by audience type, location intent, or device type to target specific user behaviours effectively.
Optimise Seasonal Campaigns
- Adjust bidding strategies for periods of high demand, such as holiday seasons. Smart Shopping campaigns and video ads can benefit from seasonal adjustments.
Combine Signals
- Smart Bidding algorithms factor in a range of signals to optimise performance. Use broad match keywords alongside audience layering for better results.
Portfolio Bid Strategies
- Manage multiple campaigns under a single portfolio bid strategy to align with broader performance goals.
Is Smart Bidding Right for Your Campaign?
Smart Bidding offers many advantages, but it’s not a universal solution. Here’s when it’s most effective:
Suitable Scenarios
- Campaigns with sufficient historical performance data.
- Advertisers aiming for scalable solutions to achieve specific business objectives.
- Goals that focus on high conversion likelihood, such as maximising conversion value.
Unsuitable Scenarios
- New campaigns with limited data.
- Situations requiring granular control over individual bids.
- Campaigns targeting niche audiences with unpredictable behaviours.
For new campaigns, manual control may yield better results initially, allowing you to build data before switching to automated bidding strategies.
