Login to Google Ads and go to Tools & Settings > Measurement > Conversions
Click the blue + button to create a new Conversion
Choose Import > Other data sources or CRMs > Track conversions from clicks
Conversion name - Give the conversion the name "Ruler Revenue"
Value - If you intend to send revenue or forecasted revenue choose "Use different values for each conversion" otherwise choose with the same value or none
Note - If you wish to send events to Google Ads for calls from Call extensions, you will need to create a separate conversion with a different name and instead of using the 'Import from Clicks' Select from Phone Calls.
