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.

On a Squarespace Core, Plus or Advanced plan, paste your SignalBridge snippet into the Header field of Code Injection, and paste it again into the Order confirmation and Order status fields. Squarespace does not allow custom code on checkout pages. Place a test order and check that one Purchase appears with the right value, and use sb_track with Squarespace's order merge tags if it does not.
