Use Product recommendation Preview to view the results of the strategies before you publish them on the channel. You can then verify whether you created the right strategy and entered enough amount of lookback timeframe to view the relevant recommendations on your channel.
Note You must save your strategy to activate the Preview button.
To preview a product recommendation strategy, complete the following steps:
- In the product recommendation strategy pane, click Preview. Once you create the strategy, it is scheduled to be run daily to generate recommendations. Preview will be available the next day.
- In the preview window, enter one or more product IDs to find out the recommendations returned for a particular product. Product ID is case-sensitive.
Note If you select Most popular as your algorithm, you can skip this step.
- Click Preview.
If you configure both primary and fallback strategy for the zone, and if the primary strategy does not provide enough recommendations, then recommendations returned from the fallback strategy are appended to the results and displayed.
Top 10 recommendations for the strategy are displayed in a zone. Use the pagination on the page to view more product recommendations.
How does preview work?
Preview helps you see the recommendations that are generated by the algorithm, and how the business rules impact the recommendations before you publish your product recommendations strategy on the channel.
The product recommendation models run once a day. Hence, to preview the product recommendations, you'll have to wait at least one day after you save the strategy. Preview shows the results only after the model runs and comes up with recommendations.
Preview is not available if there are no recommendations generated for the strategy.
Preview of the same product recommendation models
Consider a scenario in which you create a product recommendation strategy for a zone, by selecting an algorithm, Lookback time frame, and other relevant parameters. Let us name this model as ProdRecsModel1. Its preview will be available the next day.
Now, on the next day, if you create another product recommendation strategy for another zone, using the same combination of algorithm, Lookback time frame and other parameters as that of ProdRecsModel1, then the preview for the new model will be immediately available, without the need to wait for another day.
The preview shows the recommendation data as of the time that the last model was run. For example, if you update the algorithm or Lookback time frame that is defined for your strategy, then the models need be run again to show the updated results in the preview. If you create another strategy for another zone, with same algorithm and time frame, then the model runs once for multiple zones.
Product ID in preview
To preview the recommendations, you need to enter the target product ID for which you want to verify the recommendations. In case of View-to-Buy algorithms, you may enter one or more than one product ID(s) for which you want to verify the recommendations.
View-to-View and Buy-to-Buy algorithms use collaborative filtering that encompasses techniques for matching similar products based on user interactions and makes recommendations on this basis. Hence, you need to enter one product ID to view the recommendations in preview.
- Preview is not available for Most Recent algorithm as it is not machine learning algorithm.
- You can directly preview the results that are generated from Most popular algorithm as you don’t need to enter the product ID.
