Salesforce or Zapier Connection
Google Ads has a built-in integration with Salesforce where you track Salesforce qualified leads and/or sales as conversions in Google Ads. (Google also has an integration with Zapier which could do this too).
Switching from tracking phone calls and form fills to tracking actual sales increased our ROI by 30% and allowed us to increase spend in this channel.
I asked Zapier to build this, but they responded that the companies build the apps. Zapier is a middle-ground suggestion that could open up more possibilities for Microsoft Ads, but a built-in integration is preferred to remove outside cost.
Any non-e-commerce using salesforce (150K companies) would benefit from this.
