Conversion Uplift is a UK analytics consultancy led by Neal Cole, author of the official GA4/GTM audit course for CXL.com.
We specialise in trustworthy measurement; server-side tracking, GA4, BigQuery and Shopify, built and monitored so the data you make decisions on holds up when it counts.
As analytics gets automated, someone has to make sure the machine got it right. That’s us, the people who keep the data honest, and prove it when a decision, a budget or a regulator depends on it.

Tracking Events Fixed
Broken events, data-layer failures and consent gaps found and fixed, so the numbers our clients report are real.
Conversion Uplift was founded by Neal Cole, who wrote and presents the official GA4/GTM audit course for CXL, the course much of the industry trains on. After 20+ years in digital analytics, including senior roles in financial services and gaming, Neal built the consultancy on a simple principle, as AI makes analytics faster and cheaper, the thing that matters most is whether you can trust the output, and whether someone senior will stand behind it.
We’re a small, senior team. When you work with us, a named expert is accountable for the numbers you’re given, not a template, and not an unchecked machine.
Most analytics work now starts with a machine and ends with a guess. We do the opposite, start by making sure the data is true, then keep it that way. Four steps, from a free first look to measurement we monitor for you.
A read-only scan of your analytics, consent and conversion tracking that shows where you stand in minutes — and what an automated check can't see. The fastest way to find out if your numbers are lying to you.

Most teams have more data than they trust. Ad blockers and consent gaps alone can lose 10–15% of your conversions. Our AI audits your GA4 and GTM setup and our team checks every finding, so you see what's mis-tracked and what it's costing you. £250 each, or £450 for both.
→
Recover the conversions ad blockers, browser limits and privacy restrictions quietly strip from client-side tags — often 10–15% of them, and enforce consent properly. Server-side GTM gives you cleaner, more reliable, consent-compliant data your bidding and reporting can trust.
→
Move beyond GA4's sampling and retention limits. We export your raw event data to BigQuery for unsampled, full-history analysis at scale, the foundation for reporting and monitoring you can rely on, especially on high-traffic sites.
→
We don't just fix your measurement once, we monitor it continuously and verify what your AI tools report, so breakage is caught the day it happens, not three weeks later in a dashboard you'd stopped trusting.
→Conversion Uplift works with brands across the UK, Europe and beyond, including operators in Malta and Gibraltar, the heart of European online gaming. We know the measurement and consent challenges regulated sectors face, because we’ve worked where they operate.
Our experience spans diverse markets, allowing us to identify patterns, behaviours, and optimisation opportunities across different customer types.
Accurate, auditable measurement for complex, multi-step journeys and regulated reporting, where getting the numbers wrong is expensive.
Server-side and BigQuery foundations for high-volume, data-heavy platforms that have outgrown standard GA4.
Accurate ecommerce and revenue tracking end to end, so checkout, product and conversion data you report is real, not lost to broken tags or ad blockers.
Reliable, consent-compliant tracking for legal firms across consumer and B2B services, where enquiries are sensitive and data privacy has to stand up to scrutiny.
Reliable tracking across long, multi-touch booking and membership journeys.
Trustworthy, high-volume tracking for licensed operators, server-side reliability and revenue accuracy that hold up at scale and under scrutiny.
We migrated their systems to Google Tag Manager, implemented detailed form field tracking, and developed online dashboards for self-service reporting.

Conversion Uplift is led by Neal Cole, author of the official GA4/GTM audit course for CXL, not “CXL-trained” like much of the field, but the person who wrote the course. Behind him is a small, senior team with a genuine background in the sectors where getting measurement wrong is most expensive: financial services and gaming.

Neal regularly shares what we’re seeing in the field, where analytics data quietly goes wrong, what AI changes for measurement, and how server-side tracking and BigQuery keep the numbers honest. Practical, specific, and occasionally uncomfortable.
