In addition to recommending relevant queries to users when they type in the search box, Coveo Machine Learning Predictive Query Suggestion (PQS) models add an additional layer of personalization to the offerings of Query Suggestions (QS).

The “predictive” aspect provides an additional result boost based on product embeddings and vectors personalized to the user’s session when performing queries. In other words, it predicts the next query the user would have performed in the search box, and suggests it in real time, meaning that PQS also personalizes the experience for anonymous users.

Coveo ML PQS models:

  • Increase conversion by reducing friction in the shopper journey.

  • Increase search usage.

  • Increase clicks on suggestions.
