How It Works and Why It Matters:
Smart Bidding is an automated bid strategy in Google Ads that leverages machine learning to optimize bids in real time. Instead of manually setting bids for each keyword or ad group, Google’s algorithm determines the best bid based on various signals such as user behavior, device, and conversion probability.
How Does Smart Bidding Work?
Google analyzes multiple data points during each ad auction to determine the ideal bid, considering factors such as:
- User intent based on the search query
- Device type (mobile, desktop, or tablet)
- Location and time of search
- Likelihood of conversion, based on historical data
Types of Smart Bidding Strategies
Depending on your campaign goals, there are four primary Smart Bidding strategies:
- Maximize Conversions
- Focuses on getting the highest possible number of conversions within your budget
- Best for businesses aiming to generate more leads or sales
- Maximize Conversion Value

- Useful for businesses with varying conversion values, such as e-commerce stores
- Target CPA (Cost-Per-Acquisition)

- Ideal when you have a set budget per lead or sale
- Target ROAS (Return on Ad Spend)
