Key Takeaways
- Manual bidding offers granular control; automated strategies use algorithms optimizing toward specified goals.
- Newer campaigns without sufficient conversion data often benefit from starting with manual bidding.
- Target CPA and Target ROAS strategies optimize toward specific cost or return goals automatically.
- Automated doesn’t mean unsupervised — regular review remains essential.
PPC bidding strategies fall into two broad categories: manual bidding, which offers granular, direct control over individual keyword bids, and automated strategies, which use algorithms to optimize bids based on your specified goals. Choosing the right approach significantly affects both campaign performance and how much manual control you retain over individual bid decisions.
When Does Manual Bidding Still Make Sense?
Newer campaigns without sufficient historical conversion data, or accounts requiring precise budget control, often benefit from manual bidding until enough data accumulates to support reliable automated optimization.
What Is Target CPA Bidding?
This automated strategy aims to acquire conversions at or below a specified target cost, requiring reasonable historical conversion data to perform effectively, since the algorithm needs sufficient signal to optimize accurately.
What Is Target ROAS Bidding?
Particularly useful for e-commerce, this strategy optimizes bids toward a target return on ad spend rather than a flat cost-per-conversion target, accounting for the actual value of different conversions.
What Do Maximize Conversions and Maximize Clicks Strategies Do?
These simpler automated strategies optimize toward volume within your budget, useful for specific goals like early-stage traffic or lead generation growth where volume matters more than a specific cost target.
When Should You Consider Switching to Automated Bidding?
Once sufficient conversion data has accumulated, automated bidding often outperforms manual bidding by processing signals at a scale humans can’t efficiently replicate across many simultaneous variables.
Does Automated Bidding Require Ongoing Monitoring?
Yes, automated doesn’t mean unsupervised — regularly reviewing performance ensures the algorithm continues delivering results aligned with genuine business goals rather than drifting unnoticed.
How Do Accounts Typically Transition Between Bidding Strategies?
Many successful accounts begin with manual bidding, transitioning to automated strategies once enough historical data supports reliable algorithmic optimization, rather than starting with automation before sufficient data exists.
Should Bidding Strategy Match Specific Campaign Goals?
Yes, the right bidding strategy should align directly with what a specific campaign is trying to achieve, whether that’s volume, efficiency, or a specific return target.
Frequently Asked Questions
How much conversion data is needed before automated bidding works well?
This varies by platform, but generally a meaningful volume of recent conversions is needed for the algorithm to optimize reliably.
Can you switch back to manual bidding after trying automated strategies?
Yes, though switching strategies frequently can disrupt the algorithm’s learning process, so changes should be deliberate rather than frequent.
Does automated bidding always outperform manual bidding?
Not universally — it depends on data availability and campaign maturity, with manual sometimes performing better for newer or highly specific campaigns.
Should different campaigns within the same account use different bidding strategies?
Yes, bidding strategy should match each specific campaign’s goals and data maturity rather than applying one strategy uniformly across an entire account.
