What is value-based bidding?
Correct Answer
It’s a Smart Bidding strategy that relies on machine learning to deliver the highest conversion value possible by bidding for conversions that drive business objectives.
Why is this the correct answer?
Value-based bidding is a Smart Bidding strategy that relies on machine learning to deliver the highest conversion value possible within your budget. Rather than optimising purely for conversion volume, value-based bidding uses Google's AI to evaluate real-time signals at every auction and prioritise bids for users who are likely to generate the most revenue or value — such as high-order-value customers. Advertisers pass transaction values to Google Ads, allowing the algorithm to distinguish between a £10 purchase and a £500 purchase and bid accordingly.
Why are the other options incorrect?
It’s a Smart Bidding strategy that relies on machine learning to deliver the highest click-through rate possible, by bidding for conversions that drive business objectives.
Value-based bidding does not optimise for click-through rate — CTR is a metric, not a conversion value outcome, and Target CPA or Maximise Clicks are more relevant strategies for CTR-focused goals.
It’s a Smart Bidding strategy that relies on machine learning to deliver the highest target impression share possible, by bidding for conversions that drive business objectives.
Value-based bidding does not optimise for target impression share — impression share bidding is a separate strategy aimed at visibility, not conversion value.
It’s a Smart Bidding strategy that relies on machine learning to deliver the highest impressions possible, by bidding for conversions that drive business objectives.
Maximising impressions is the goal of Target Impression Share bidding, not value-based bidding — value-based bidding focuses on the downstream revenue value of conversions.
Real-World Example
An e-commerce retailer selling products ranging from £15 accessories to £400 headphones implements value-based bidding by passing actual purchase values to Google Ads. The Smart Bidding model learns to bid higher for users with signals suggesting intent to buy premium products. Within 90 days, total conversion value increases by 38% while spend grows by only 12%, as the algorithm efficiently allocates budget toward higher-value customers.
