When creating a new campaign for a shop's promotion of jackets, shoes, and handbags, why is it recommended to create separate campaigns for each line of merchandise?

Creating separate campaigns for distinct product lines like jackets, shoes, and handbags allows for highly specific messaging tailored to each product category. This ensures that ad copy, keywords, and landing pages are perfectly aligned with what a potential customer is searching for, leading to higher relevance and better ad performance. Furthermore, it enables individual Return on Investment (ROI) optimization, meaning you can allocate budgets, adjust bids, and refine strategies based on the unique profitability and performance of each product line. This granular control is crucial for maximizing overall campaign effectiveness and efficiency. The other options are incorrect because separate campaigns do not inherently restrict responsive search ads, prevent Google AI from using automated bidding (which is often beneficial), or enforce a keyword limit.
