Ad blockers, browser extensions and Safari ITP lose most sites 10% to 15% of the conversions their ads deliver. At £1m a year on paid media, that’s a six-figure bidding decision made on the wrong number.
We fix the tracking behind your Google Ads, Meta and GA4 reporting so you bid on complete data and can reconcile what GA4 reports against your back-end. Neal Cole, who wrote the official GA4/GTM audit course for CXL, signs off every finding.

Proud to Work With Businesses That Value Insights
Ad blockers, browser extensions and Safari ITP stop 10% to 15% of conversions reaching client-side tags. Server-side tracking sends them to Google Ads and Meta with enhanced conversions attached, so Smart Bidding sees the full picture.
Key events fire twice, purchase values arrive as strings, the product array is missing on half the templates. Fix the data layer and GA4 revenue matches your back-end, so you can bid on margin instead of revenue.
GA4, Google Ads and your CRM each report a different number for last month. Join them in BigQuery and you get one figure per channel you can reconcile against invoiced revenue.
Weekly releases, three teams touching the site, a tag edited on a Friday. Daily monitoring means you find out the day it breaks, before the budget is spent on it.
Our team knows Google Analytics 4, server-side Tag Manager, BigQuery and Shopify tracking inside out. This is the engineering that’s hard to get right, and hard for AI to fake.
Setting up analytics is the easy bit. The value is knowing the numbers are true, and having someone experienced tell you what they mean for the decision in front of you. Not a dashboard. A person who’s accountable for the answer.
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 GA4, GTM, consent banner and conversion tracking, back in minutes. You get a plain list of what to fix first, so next month's Google Ads and Meta budget is set on numbers you've checked rather than assumed. No account access needed.

A fixed £250 + VAT each, or £450 + VAT for both. Our AI checks every tag, trigger, event and conversion in your GA4 and GTM setup, and one of our team checks every finding. You come out with the data layer, key events and enhanced conversions set up the way Google Ads bidding expects, so Smart Bidding runs on complete data rather than a sample of it.

Ad blockers, browser extensions and Safari ITP take 10% to 15% of conversions out of client-side tags. Server-side tracking through sGTM sends them to Google Ads and Meta with user-provided data and enhanced conversions attached. Bid on margin instead of revenue, build audiences you can actually target, and stop under-reading ROAS on the channels that work. At £1m a year of paid media, that's a six-figure decision now resting on the right number.

Raw event data in BigQuery, joined to your CRM and back-end sales data. That gives you year-on-year comparison past GA4's 14-month retention, customer lifetime value by channel, and reported revenue you can reconcile against invoiced revenue. If your ecommerce site is near the 1m daily event export limit, we handle that too, so you're not forced into £20k to £30k a year on GA360.

Weekly releases, three teams touching the site and one tag edited on a Friday: tracking breaks between audits. We monitor your GA4, GTM and ad platform conversions daily, and check what your AI reporting tools say against the source data. You find out the day it breaks, before the budget is spent on it. One childcare brand was under-reporting revenue by over 90% before anyone looked.
→Years of Hands-On Experience
Led by Neal Cole, author of the official GA4/GTM audit course for CXL, – with an experienced team that’s worked with leading brands across eCommerce, finance, legal, accounting, SaaS and gaming.
Our clients recover lost conversions, fix leaking revenue, and finally trust the numbers they report to the board.
AI can generate the analysis in seconds. We’re the humans who verify it before you bet a budget on it, the check between the machine’s answer and your decision.
We don’t just hand you data. An experienced analyst tells you what it actually means for the decision in front of you, and puts their name to it.
Measurement drifts the moment your site changes. We monitor tracking, consent and conversions continuously, so the next break is caught the day it happens, not a quarter later in a report.
We start with your business - what decisions you make on your data, where the money is, and what you can't currently trust.
We assess tracking accuracy, data quality, consent and reporting gaps, what's firing, what isn't, and what it's costing you.
We set out what "correct" looks like: the key events, conversions and definitions your reporting should hold to.
We configure GA4, server-side GTM and conversion tracking properly, and set it up so it stays right, not just right today.
We test every critical journey end to end and confirm the numbers reconcile, so you know the data is true before you act on it.

The client struggled with data quality issues due to the limitations of free Google Analytics 4, given the high traffic volumes on their site. Solution: We exported raw data to BigQuery and set up automated dashboards to leverage tabular analysis directly from BigQuery.
