You work at an agency and one of your clients wants to track performance by product category (ex: apparel) and gender. They already passed the optional and required attributes for apparel in the product feed. How could they achieve granular reporting?

The client wants granular reporting by product category and gender. Creating a campaign by product category and gender (e.g., "Women's Top") directly aligns with this goal. Within that campaign, using product groups (e.g., "Sweater," "Short Sleeves") allows for further segmentation and performance analysis for specific product types within that category and gender combination. This structure provides the most precise reporting for the client's stated needs. "Create a catch-all campaign" would not provide granular reporting. "Create a campaign for each gender, then set up product groups by apparel type" would allow reporting by gender and then by apparel type, but not directly by category and gender in the campaign name, making it less intuitive for the desired reporting. "Create a campaign by product category, then set up product groups by gender" is similar; it reverses the hierarchy, making it harder to see combined performance at the campaign level.
