Conversion-based bidding strategies (including target CPA and Target ROAS bidding strategies) consider only conversions reported in the ‘Conversions’ or ‘Client account conversions’ column when optimising towards your target. Machine-learning bidding models take time to adapt to any changes that you make to your conversion configuration. This is true for all conversion settings in a campaign. If you decide to change your Search campaign's conversion actions, you should update your targets gradually over time as the bidding models adjust to newly reported conversion data. Otherwise, you may see unwanted fluctuations in performance.
Google Ads shop visits and shop sales differ from other conversions in that the automated bidding system will react immediately to adding or removing the conversion action. You should update your targets as soon as shop visits or shop sales are added or removed from the ‘Conversions’ or ‘Client account conversions’ column.
