Smart Bidding
Google Ads' automated bid strategies that use machine learning to optimise for conversions or conversion value at auction time. Strategies include Target CPA, Target ROAS, Maximise Conversions, and Maximise Conversion Value.
How Smart Bidding works in practice
Smart Bidding requires sufficient conversion volume to learn effectively — Google recommends at least 30 conversions per month per campaign for Target CPA, and proportionally more for Target ROAS. New campaigns should start with Maximise Conversions (no target) to build the conversion history needed before switching to a target-based strategy. Smart Bidding performs best when conversion tracking includes all revenue-generating actions (not just final purchases) and when conversion values reflect actual revenue differences between product lines. Seasonality adjustments can be applied manually before high-traffic periods like product launches or market events to prevent the algorithm from under-bidding during unexpected demand spikes.
