Senior GA4 & GTM Consultants – London
We help UK businesses stop guessing and start growing with accurate data.
TagGurus is a London-based digital analytics agency specialising in Google Analytics 4 and Google Tag Manager. Founded by a senior consultant with 15+ years of hands-on experience, we work with marketing teams and ecommerce businesses across the UK to fix broken tracking, deploy GA4 correctly, and make sure your data actually reflects your business.
Our Mission
Most businesses are making decisions based on incomplete or inaccurate data. GA4 setups that miss key events. GTM containers full of outdated tags. Conversion tracking that doesn't match reality.
We exist to fix that.
Every engagement at TagGurus is handled personally by a senior consultant — no juniors, no handoffs, no account managers in between. You get expert-level work with fast turnaround and direct communication from day one.
What We've Done
Over the past 15 years we have delivered analytics projects for brands including Topshop, Topman, Hostelworld, Graze, Inside Japan Tours and Cotopaxi — across retail, travel, food and lifestyle sectors. We have worked with both enterprise-scale businesses and small independent operators, which means we understand what good data looks like at every level.
