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 optimizing towards your target. Machine learning bidding models take time to adapt to any changes 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 conversions data. Otherwise, you may see unwanted fluctuations in performance.
Google Ads store visits and store 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 store visits or store sales are added or removed from the "Conversions" or "Client account conversions" column.
