Imagine pouring money into Google Ads but not seeing the results you expected. Are you leaving conversions on the table? Selecting the most effective approach ensures cost efficiency, maximizes ROI, and helps align ad spending with business goals. When running Google Ads campaigns, choosing the right bidding strategy can significantly impact your ad performance and return on investment. Two primary options are Smart Bidding, powered by machine learning, and Manual Bidding, which gives advertisers direct control over bid adjustments. But which approach works best for your business? In this article, we compare Google Ads Smart Bidding and Manual Bidding to help you determine the best strategy for your needs.
What is Smart Bidding?
Smart Bidding is a set of automated bidding strategies that use machine learning to optimize for conversions or conversion value in each auction. Google’s algorithms analyze vast amounts of data to adjust bids dynamically in real-time.
Key Smart Bidding Strategies:
- Target CPA (Cost Per Acquisition) – Adjusts bids to help get as many conversions as possible at your target cost per action.
- Target ROAS (Return on Ad Spend) – Aims to achieve the highest conversion value based on your return-on-ad-spend goal.
- Maximize Conversions – Uses your budget to get the most conversions possible.
- Maximize Conversion Value – Focuses on maximizing the total conversion value within your budget.
- Enhanced CPC (eCPC) – Adjusts manual bids based on the likelihood of conversion while maintaining some manual control.
What is Manual Bidding?
Manual Bidding allows advertisers to set individual bids for keywords, ad groups, or campaigns. This method gives complete control over bid adjustments based on performance insights and business objectives.
Key Features of Manual Bidding:
- Ability to set custom bids at the keyword level.
- Full control over budget allocation.
- Requires ongoing bid adjustments and performance monitoring.
