Leaf launches Signal: the tracking solution tackling one of eCommerce’s biggest performance risks

Published: February 17, 2026 at 12:31 pm

Newcastle-based performance intelligence company Leaf has announced the launch of Leaf Signal, a fully-managed server-side conversion tracking & AI-powered monitoring solution for eCommerce brands. 

Signal addresses what Leaf describes as the most critical but underinvested part of the performance marketing chain: conversion tracking. According to Leaf, broken tracking affects 97% of the eCommerce brands it audits, silently and significantly undermining paid media performance, analytics accuracy and marketing profitability.

Leaf Signal improves the abundance, accuracy, richness and reliability of data flowing into ads, email and analytics platforms through a combination of advanced browser and server-side tracking, first-party data enrichment, AI-powered monitoring and ongoing expert support. The result is enhanced attribution, improved data integrity and stronger foundations for profitable performance marketing, in a privacy-first era.
