Each type of product recommendation has different data dependencies, and the Insight data checker can identify issues in your data. This tool appears in the sidebar when you create a new product recommendation.
The checks identify two categories of problem:
You can still create the recommendation, but the results will not be optimal.
The state of the data prevents us from creating a recommendation.
The Insight data checks on two levels: catalog and product. The catalog level will let you know that your schema is wrong, whereas the product level will zoom in on the specific product that's causing the problem.
The below table details the Insight data checks that we perform.
Checks whether the dependent Insight data collections use a valid schema (i.e. they have the correct fields).
Checks whether each product has a unique SKU. This field should be unique, otherwise, your best sellers may wrongly attribute sales.
Checks whether your products have valid links. Without a valid link, contacts will not be able to click through to view the product. Links should be full URLs pointing to your live website.
