The main flows

The following diagram describes how Optimizely Product Recommendations works in both tracking modes.

• Server-side API integration
• Client-side API integration

Integration API

Server side

• The EPiServer.Tracking.Core package
  • The EPiServer.Tracking.Core.ITrackingService interface.
• The EPiserver.Tracking.Commerce package
  • The EPiServer.Tracking.Core.TrackingServiceExtensions class.
  • The EPiserver.Tracking.Commerce.CommerceTrackingAttribute class.
  • The EPiServer.Tracking.Commerce.TrackingDataFactory class.

Client side

• The _EPiServer.Personalization.Commerce_package
  • The epiRecommendations JavaScript object. Use this to send a tracking request with the given tracking data, collected in the client. It renders the tracking response.
  • The TrackingDataFactory JavaScript object. Collects tracking data from the client.

Marking clicks

• If a user clicks a recommended item, the click must be tracked to generate useful recommendations. To get information about which recommendation triggered the current request, use the EPiServer.Tracking.Commerce.IRecommendationContextinterface.
  • The Quicksilver template has a class, EPiServer.Reference.Commerce.Site.Features.Recommendations.Services.RecommendationContext which implements the above interface, to track clicks on recommended products.

Preparation

Defining recommendations layout on a page

To render recommendations, create four sections on a page: upper, left, right and bottom.

• recommendations-upper
• recommendations-left
• recommendations-right
• recommendations-bottom

Based on their CSS classes (above), recommendations are rendered to the upper, left, right and bottom of a page's main content.

In Views/Shared/_Layout.cshtml, add 4

<div class="recommendations recommendations-upper"></div>
    <div class="recommendations recommendations-left"></div>
    <div class="recommendations recommendations-right"></div>
    <div class="recommendations recommendations-bottom"></div>

@{ Html.RenderAction("Index", "Navigation"); }
    <div class="quicksilver site-wrapper">
        <div class="main-area">@RenderBody()</div>
        <div class="recommendations recommendations-upper"></div>
        <div class="recommendations recommendations-left"></div>
        <div class="recommendations recommendations-right"></div>
        <div class="recommendations recommendations-bottom"></div>
    </div>
    @{ Html.RenderAction("Index", "Footer"); }
