About "Switch to DDA" (data-driven attribution)

Use the "Switch to DDA" page in the attribution reports in Google Ads to quickly switch eligible conversion actions from rules-based attribution models (such as "Last click") to data-driven attribution.

About data-driven attribution

Data-driven attribution gives credit for conversions based on how people engage with your various ads and decide to become your customers. When possible, it uses data from your account to determine which keywords, ads, and campaigns have the greatest impact on your business goals. Data-driven attribution looks at website, store visit, and Google Analytics conversions from Search (including Shopping), YouTube, Display, and Demand Gen ads.

Note: Data-driven attribution support for Demand Gen campaigns is rolling out in the coming months.

Benefits

By switching from a rules-based model to data-driven attribution, you can:

  • Learn which keywords, ads, ad groups, and campaigns play the biggest role in helping you reach your business goals.
  • Optimize your bidding based on your specific account's performance data.

Auto-switch conversion actions

Some conversion actions may be selected for automatically switching to data-driven attribution. If you have administrative access to your Google Ads account, you'll receive an email 30 days before any changes will take place. You can do nothing to let the scheduled switch happen, or you can go to the "Switch to DDA" page to opt out or switch earlier.

Note: The "Switch to DDA" page only includes conversion actions that are currently supported by attribution in Google Ads.
