Focused engagements where measurement quality is the bottleneck.

I work on focused engagements where measurement quality is the bottleneck. Most clients come to me for one of these four things.

01

Measurement framework design

The foundation. A measurement framework defines what you’re trying to learn, the KPIs that prove it, and the events and properties that feed them — so reporting becomes a by-product instead of an emergency.

  • KPI hierarchy aligned to business objectives and OKRs
  • Event taxonomy and naming conventions
  • Data layer specification
  • Tracking plan documentation your developers can actually implement
  • Validation checklist

Good fit when — you're rebuilding the site, launching a new product line, or your current reporting tells you what happened but not why.

02

Analytics implementation & audit

GA4 and GTM are my home turf, but I work across the broader analytics stack. I audit what you have, fix what’s broken, and implement what’s missing — without leaving a tangle of legacy tags behind.

  • Full GA4 / GTM audit with prioritised findings
  • Equally at home in non-Google stacks: Adobe Analytics, Matomo, Piwik PRO, Mixpanel, Amplitude, Contentsquare, Umami
  • Data layer implementation (or fix)
  • Server-side tagging where it earns its keep
  • Consent mode configuration aligned to your CMP
  • Cross-domain and subdomain tracking
  • QA via Tag Assistant, GTM preview, and DebugView

Good fit when — your numbers don't match across tools, your team doesn't trust the data, or you're moving from UA to GA4 properly.

03

Migration analytics

Replatforms, redesigns, and consolidations are where tracking quietly dies. I make sure SEO equity, historical data, and event integrity survive the transition.

  • Pre-migration baseline and tracking inventory
  • URL mapping and 301 strategy
  • GTM container and data layer migration
  • Post-launch validation and parity reporting
  • Rollback criteria and monitoring window

Good fit when — you're replatforming (Shopify, Commerce Cloud, custom), consolidating sites, or rebuilding the front end.

04

Reporting & enablement

Dashboards that get opened, plus ad-hoc analysis when leadership needs an answer fast — and the team enablement that makes both stick after I leave.

  • Dashboards in Looker Studio, Looker, or Power BI
  • Ad-hoc analysis and deep dives: funnel breakdowns, segment comparisons, campaign post-mortems, one-off business questions
  • Connected data sources and automated refresh
  • Documentation aimed at the people who'll use them, not the people who'll build them
  • Team workshops on framework, GA4, and tag governance

Good fit when — your reports take too long to make, get ignored when they're done, or live in someone's head.

Engagement shapes

Most engagements fall into one of three shapes.

Audit 1 — 3 weeks
Fixed-scope review of an existing setup or process.
Project 4 — 12 weeks
Defined deliverable — framework, migration, dashboard suite.
Retainer Monthly
Ongoing senior analyst capacity.

Pricing is project-specific. Get in touch with a rough description and I'll come back with a proposal.
