Tracking and analytics, both included: set up, checked every morning, and a monthly report on which spend actually brings sales. Everything you’d hire an analyst for, at $500 a month and none of the hiring. AI does the daily checks. I approve every change.
Salary: average US marketing analyst, $80,409 a year (Indeed, June 2026). Before benefits, payroll taxes and tools.
Accurate data is step one. Knowing what works is the point. Every setup is checked against real orders and leads from your store or CRM. A healthy setup records 85 to 90% or more, measured one to two weeks after the fix goes live. Where visitors must accept cookies first (UK, EU), the gap can be much bigger. In that case I show you, with evidence, that the tracking is accurate and that the rest is people who said no to cookies.
Each one looked fine in the dashboards. The problem only showed up when we compared the numbers with real orders and leads.
What broke: the first version of the lead tracking caught 90% of leads. The second overshot and reported 130%. Ads looked better than they were.
How it was caught: matching every lead against the CRM, not trusting the platform’s count.
After the fix: 99% of leads tracked, checked against the CRM.
What broke: 41% of UK orders had no visit data behind them, against 12% in the US. The UK consent setup and the store’s privacy settings were fighting each other.
How it was caught: comparing orders by country, one month at a time.
After the fix: UK purchases tracked went from 57% to 69–78%. The remaining gap is shoppers who declined cookies, which no setup is allowed to record.
What broke: the website and the app lived on two different domains. The sign-up buttons sent unfilled blanks instead of the campaign details, so sign-ups lost the ad that brought them.
How it was caught: reading the actual links, button by button, across 16 pages.
After the fix: every sign-up button carries the campaign into the app.
They can’t all be right. Ad platforms count every sale they touched, including people who were going to buy anyway. I check their numbers against your real sales and show you which spend is pulling its weight, and which isn’t.
Clean data within two weeks, then daily checks, fixes, new tracking, weekly reports, dashboards and your vendors handled. Every month has to be worth it.

John“John doesn’t just install tracking, he thinks in systems. When something is off, he doesn’t guess. He audits, isolates variables, and fixes root causes. That’s rare.”
“Solved a problem we’ve tried to fix for months… in an hour.”
“John has become a regular hire for our agency to help us navigate GA4. Excellent knowledge and communication.”
For more than 10 years I’ve built and run the tracking and analytics behind ads and reports for ecommerce brands, lead-gen businesses and marketing agencies in the US and Europe: what gets measured, how it reaches GA4, BigQuery and the ad platforms, and the reports and dashboards teams make decisions with.
Before going independent I was a Senior Customer Success Manager at Fueled, a Shopify tracking company. I studied psychology, so I care about what the numbers say about real customers, not just whether they add up. I’m based in Barranquilla, Colombia, and work on US Eastern hours.
You add me as a user in Google Tag Manager, GA4 and your ad platforms, the same way you would add an employee. The daily checks use view-only access, and you can remove me any time.
I reply within one business day with what I need. Then I compare your real orders or leads with what each platform recorded, and walk you and your team through what I found on a call.
I work with order or lead IDs, never customer names, emails or card details. No customer data goes to AI, and I am happy to sign an NDA before we start.
85 to 90% or more of your real sales or leads, measured one to two weeks after the fix goes live. Where visitors must accept cookies first (UK, EU), the gap can be much bigger. In that case I review it with you and show, with evidence, that the tracking is accurate and the rest is people who said no to cookies.
Website builds, platform migrations (a new store or CRM, for example) and anything over 10 hours in a month. I quote those separately before starting.
Yes. I can run tracking for your clients under your brand. See agency plans →
Tell me where to look. Within one business day I’ll reply with what I need, usually a 30-day export of order or lead IDs plus screenshots from your ad platforms. IDs only, never names, emails or card details. Your privacy and security come first, I’ll ask for anything else step by step, and I’m happy to sign an NDA before we start.
