To both drive conversions and track how those conversions are prompting users to respond, what should you set up in Search Ads 360, along with a data-driven attribution model?

To effectively drive conversions and understand user responses, custom channel groupings are essential. This allows you to define and organize your marketing channels in a way that aligns with your specific business objectives and reporting needs. When combined with a data-driven attribution model, custom groupings provide granular insights into which channels contribute most to conversions and how users interact across these defined paths. Automated channel groupings are predefined and may not offer the necessary flexibility for detailed analysis. Keyword groupings are for organizing keywords, not channels. Multichannel groupings are a broader concept, but "custom channel groupings" specifically refers to the actionable setup within Search Ads 360 for this purpose.
