Google Analytics consultant. GA4 expert. Decision-grade measurement.
Independent GA4 consultant specialising in audits, setups, tracking fixes, and training for businesses.
Marc Alexander is an independent GA4 Consultant based in London, with nine years’ experience helping businesses from startups to global brands build Google Analytics they can actually trust.
He fixes the stuff that quietly ruins decision-making: conversions firing twice (or not at all), checkouts that break sessions, revenue that never matches the payment processor, UTMs doing interpretive dance, and cookie consent setups that look compliant until you test them properly.
The outcome is simple: measurement that reflects reality, not optimism.
Marc works across GA4, Google Tag Manager (GTM), and BigQuery, with privacy-first implementation aligned to UK GDPR and the Data Protection Act 2018.

Some of the GA4 services that Marc offers.
GA4 services for UK & EU businesses
GA4 Audit: find and fix what’s broken
Most GA4 properties have a handful of issues that undermine reporting and paid media optimisation.
Marc’s 38-point GA4 audit pinpoints the exact failures across tracking, e-commerce, cross-domain journeys, integrations, and compliance—then prioritises fixes by business impact (not “because GA4 allows it”).
Three tiers:
-
Mini Audit (£175–£300),
-
Full Audit (£600–£900),
-
Full Audit + Fix (£1,000–£1,800).
Expert GA4 Setup: build it properly from day one
Marc builds custom GA4 setups based on how the business actually makes money—proper e-commerce, lead gen tied to CRM, cross-domain tracking that survives payment gateways, and a measurement plan your team won’t abandon after a week.
Includes measurement planning, GTM configuration, event structure and naming, conversions, e-commerce/lead tracking, cross-domain/subdomain setup, Consent Mode v2, Google Ads + Search Console linking, QA and documentation.
-
Basic Setup (£350–£600) for straightforward sites.
-
Advanced Setup (£850–£1,300) for complex requirements (BigQuery, server-side GTM, CRM, multi-domain).
GA4 Training: make the team self-sufficient
Marc runs GA4 training using your actual GA4 property and real data (no generic demos, no “imagine you’re an e-commerce brand selling socks”). Sessions can cover GA4 fundamentals, Explorations, attribution, GTM implementation, BigQuery basics, and SQL for analysts.
-
Half-day workshops (£800–£1,200),
-
Full-day intensives (£1,500–£2,200),
-
Multi-session programmes (£3,000–£6,000).
BigQuery integration: unlimited, unsampled analysis
When the GA4 interface runs out of road, BigQuery integration unlocks raw event-level data for SQL analysis, longer retention, joined reporting with CRM/sales systems, custom attribution, and dashboards without GA4 interface limits.
Marc handles GCP setup, GA4 export, schema documentation, query templates, transformations, BI connections, and cost controls.
Why you should work with Marc.
Independent, senior expertise. No agency overhead. No account manager. No junior “learning experience.” Clients work directly with Marc—the person doing the implementation, the testing, and the explanation.
Plain-English analytics (without the theatre). Marc explains GA4 clearly and calmly. If something doesn’t make sense, it gets explained better. Nobody leaves a call feeling like GA4 is a personality test.
Fixes what moves the needle. Not every GA4 issue is worth fixing today. Marc prioritises the problems that affect revenue, attribution, conversion rate optimisation, and decision confidence.
Built to last. Documentation, governance, and training are baked in. The goal is a setup your team can run, not one that requires permanent consultant dependency.
Marc's professional experience.
Common GA4 problems Marc solves.
“Our GA4 is broken but we don’t know where to start.”
Start with the audit: https://www.metricowl.co.uk/services/38-point-ga4-audit
“Revenue in GA4 doesn’t match Shopify/WooCommerce/Stripe/our payment processor.”
Typically event sequencing, missing item data, or cross-domain attribution issues—audited and fixed properly.
“Checkout breaks attribution and everything turns into Direct.”
Cross-domain configuration and referral exclusions set correctly, validated end-to-end.
“Events work in GTM preview but don’t show in GA4.”
Often timing, consent, or trigger logic. Marc isolates the root cause and resolves it.
“Our team still hates GA4 after Universal Analytics.”
Training tailored to your data, your questions, and your workflows: https://www.metricowl.co.uk/services/ga4-training
Marc's latest GA4 articles.
Marc writes about the GA4 problems nobody puts in the project plan: attribution that breaks at checkout, analytics implementations that "work" until someone asks a real business question, and the gap between having data and actually being able to use it. Plain-English guides for when GA4 stops being theoretical.
