To maximize performance, how should you set up your Smart Shopping campaigns?

Consolidating Smart Shopping campaigns allows Google's machine learning algorithms to operate with a larger pool of data, leading to more efficient optimization and better performance. Creating separate campaigns should only be done when there's a clear strategic reason, such as different profit margins, distinct promotional offers, or targeting specific geographic regions that require separate budgets. Launching an excessive number of campaigns (like 150 or 100) fragments data, hindering the algorithm's ability to learn and optimize effectively. While machine learning is powerful, it still benefits from consolidated data for optimal performance rather than being spread across numerous, smaller campaigns.
