# Events

For better insights into your customers, we evolved the events to use structured event data. This benefits you by improving customer results, improving conversions and giving a more detailed reporting dashboard.

If you are using Widgets supplied by Visii all their events are already tracked. You do need to add these events elsewhere on your site.

Personal information

Sending us information about your customers helps us improve results - but unless approved by us please do not send any personally identifiable information. Truncate IP addresses and anonymise any data that could be used to identify an individual. Details in our privacy guide.

User tracking

We request that you send a GDPR compliant page_view_id value when requesting results from the Vision API.

Once a user consents, add the anonymous_id and user_id so these can be mapped to purchases.

Other event properties detailed can also be passed in the v query string parameter when using the Vision API endpoints.

E.g. /explore?v=user_id:7462402,page_type:pdp,page_view_id:123456789

# Page Scrolled

Fire this event after the user scrolled the page or jumped to a different section in the page. To help you decide if the event is meaningful consider this:

  • Did the user jump to a section showing product recommendations? E.g. "Trending", "Recently Sold", "New Products", "Frequently bought together", "Customers who viewed this item also viewed"
  • Were the products generated by Visii? E.g visii-similar
  • Did the user see other products that weren't previously visible in the viewport?
  • Were new products added to the page? This could happen when infinite scrolling is supported or the user reached the end of page and you load new product suggestions.

The event is useful when you want to report new products_seen.

Avoid spamming

Attention should be payed to avoiding sending the same information multiple times. Users can scroll up and down the page multiple times while deciding what they like. Once all products were seen there is no need to report scroll events for the current page.

Property Type Description
product_id String The product ID used when using the Admin API (to push content) or Vision API (to get recommendations) (Optional)

# Custom Events

If you consider other events will be helpful to better understand the user behavior or you want that knowledge to be integrated into your client dashboard you can use custom events.

They follow the same format as standard events, having the same Common Event Properties. The data object can have additional fields related to your custom event.

// Example using Visii Analytics script - the event properties object is the "data" field for the track endpoint

// Example using all available properties
window.visii.track("My custom event", {
  anonymous_id: "8c772995-b629-4051-a4e9-b7a30dbe5b32",
  user_id: "7462402",
  page_type: "pdp",
  page_view_id: 157783680000012345,
  timestamp: 1577836800000,
  ab_tests: [
    {
      name: "visii-recommends",
      group: "visii"
    },
    {
      name: "homepage-cta",
      group: "control"
    }
  ],
  customEventKey: customEventValue
});

// Example with required properties
window.visii.track("My custom event", eventData);
