To create the first recommendation strategy:

  1. In the Frosmo Control Panel, in the sidebar, select Data Management More > Recommendations > Strategies.
  2. Click Create recommendation strategy.
  3. Define the following settings:

    • Name: Enter "Most popular on site with half affinity". Note that the ID automatically completes to "most-popular-on-site-with-half-affinity".
    • Page type: Select other.
    • Algorithms: Select the following algorithms (in order):
      • Most viewed on the site in the past 24 hours, 5 items
      • Most bought on the site in recent days, 5 items
    • Affinity: Set the slider to half-way (50%). This means that a visitor's affinity for an item counts for 50% of the item's final recommendation ranking. The algorithm determines the other 50%.
