You need to add Radar to your ecommerce site as part of the Value Engineering service. Algolia will send you a Radar script configured for your site.

​
Before you begin

  • Confirm that Algolia has sent you the Radar script for your site.
  • Add the script only to the agreed website, language, and currency.
  • Avoid changing your website’s HTML during the data collection period, because changes can affect the quality of the event data.

​
Add the script directly to your site

Add the Radar script directly to pages on your live site. Add it to the<head>tag on every page in your shopping journey, including:
  • Search pages.
  • Search results pages.
  • Product detail pages.
  • Checkout pages.
If your site uses a Content Security Policy (CSP), add these endpoints to the allowlist:
  • https://cdn-us.algoliaradar.com or https://cdn-eu.algoliaradar.com: loads the Radar script.
  • https://insights.algolia.io/1/searches: receives search events.
  • https://insights.algolia.io/1/events: receives click, shopping cart, and conversion events.
