This recommendation type is ideal for your home page. If your store does not sell unique SKU's every 30 days, we do NOT recommend this widget, as they recommendations will look old when your visitors come back to your home again. Recommendations can make or break visitor engagement, as recommendations that are not refreshed, typically lead to low visitor engagement, thus bounce. 

Tagalys will show a carousel of the top selling SKU's across your catalog, to keep your home page fresh and engaging.
