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.
“In today’s landscape, tracking is targeting,” said Gilbert Corrales, CEO at Leaf (pictured). “If your conversion data is incomplete or inaccurate, every downstream ‘decision’ suffers – from algorithmic bidding and paid media optimisation, to web analytics measurement reporting and commercial forecasting.”
Originally developed to support Leaf’s own performance marketing clients, Signal has evolved into a core standalone product now used by a rapidly growing number of data-savvy eCommerce brands.
“Over the years, we’ve seen first-hand how poorly implemented conversion tracking quietly erodes paid media profitability,” Corrales added. “It’s an issue that impacts nearly every brand we audit and directly affects revenue generation and marketing ROI”.
“Signal is the result of 15 years’ experience in the trenches – combining technology and human expertise to fix, enhance and maintain tracking, so brands can regain control over algorithmic bidding and trust in measurement accuracy.”
Early adopters report improved paid media performance, confidence in their data and reduced risk during high-pressure trading periods.
Nick Horton, growth lead at SURI, said: “Leaf Signal delivered an outstanding service by combining a comprehensive tracking audit, server-side tracking and continuous monitoring of our events. We’re instantly alerted if anything goes down, dramatically reducing potential impact. Heading into peak periods, having the reassurance that our tracking is being continuously monitored gives us real peace of mind.”
Thomas Parrott, interim CEO of NIO Cocktails, added: “When coming into any eCommerce business, my primary objective is certainty in the information that allows the business to trade profitably. Having implemented Signal in previous operations, I’ve seen how quickly data integrity improves – enabling more accurate media buying decisions and a clearer picture of what actually moves the needle.”
Callum Mitchell, senior eCommerce reporting manager at DASH Water, said: “We chose Signal because we were looking for a tool that could simplify and centralise our tracking. Beyond that, it’s helping us maximise the data we capture and feed back into our media platforms.”
Leaf Signal is available now, with brands starting with a complimentary conversion tracking audit.
