Radar is an Algolia data connector. It collects pseudonymized behavioral event data from your ecommerce site for the Value Engineering service. Algolia configures Radar for you and sends you a JavaScript snippet to add to your site. Radar collects search, browse, click, shopping cart, and conversion events during the data collection period. Algolia uses this event data with your product catalog to review your search and discovery experience. Algolia also uses the data to find ways to improve ranking and relevance, and to build a tailored demo.

​
How Radar works

Radar runs in the background on your site. It uses event listeners to collect behavioral event data. It then sends that data to Algolia. Radar doesn’t block browser interactions. It sends events in the background. Because of this, the browser might drop some events if the page closes, the network fails, or the browser blocks the request.

​
Why Radar is needed

Value Engineering requires data that reflects your current search and discovery experience. Radar gives Algolia the event data needed to:
  • Identify ranking and relevance issues.
  • Find no-result, no-click, and low-click queries.
  • Fine-tune Dynamic Re-Ranking, Query Categorization, and NeuralSearch models.
  • Estimate the impact of ranking and relevance improvements.
  • Build a demo based on your product catalog and user behavior.
Radar must collect event data directly from your site. Shared analytics exports aren’t supported for the Value Engineering service.
