SignalBridgeThe two sides
Taboola by Realize
Connect your Taboola Backstage credentials in SignalBridge, create an event-based conversion in Taboola Realize for each SignalBridge event name you want (for example make_purchase), and install the SignalBridge script. When a visitor who arrived from a Taboola ad converts, SignalBridge sends a postback with the tblci click ID, the event name, revenue, currency and order ID.

In Script Manager create a script with the location set to all pages, paste your SignalBridge snippet, and make sure the store uses Optimized One-Page Checkout so scripts can load on checkout and the order confirmation page. Connect your ad platforms, place a test order, and check that one Purchase appears with the right value. If the total is missing, send the order yourself with sb_track from an order confirmation script.
