If your client often changes keywords in their campaign as a reflection of the previous week's sales, what would you recommend they use in Search Ads 360, along with their data-driven attribution model, so that the campaigns update correctly?

Automated channel groupings are the best recommendation because they dynamically organize campaigns, ad groups, and keywords based on predefined rules. This automation ensures that as keywords change frequently due to sales performance, the groupings update automatically, maintaining accurate data flow for the data-driven attribution model without manual intervention. Custom channel groupings are static and would require constant manual updates as keywords change, making them inefficient for this scenario. Multichannel groupings are a general concept for analyzing performance across channels, not a specific feature for dynamic keyword organization within Search Ads 360. Keyword groupings are a broad term and don't specifically refer to an automated feature within Search Ads 360 that dynamically updates based on changing keywords.
