I help online businesses connect their marketing spend to real revenue — by making their data accurate, complete, and actually useful for decisions that matter.
Digital Analytics Consultant
Most businesses have data — but not the right data, connected in the right way. I fix that, from the foundation up to the revenue view.
I map where your data breaks between marketing spend and actual revenue — GA4 vs CRM mismatches, missing offline conversions, attribution blind spots, and consent bias. Clear, prioritised findings delivered in 3–5 days.
Accurate, GDPR-compliant event tracking built on your existing stack — GA4, GTM, server-side tagging, and ecommerce events. The foundation everything else depends on.
Connect GA4 to your CRM (HubSpot, Salesforce) so your ad platforms optimise on real revenue signals — not just clicks. Directly improves ad performance and enables true ROI tracking.
Custom attribution models and session stitching in BigQuery — for teams that need channel performance beyond GA4's limits. Fix "direct / not set" issues and tie every touchpoint to revenue.
Quantify exactly how much data you're losing due to consent restrictions, and how biased your current reporting is. Includes server-side and modelling recommendations for EU-compliant data recovery.
Monthly retainer: I make sure your data doesn't silently break and cost you money. Automated checks, attribution validation, tracking QA after releases, and a monthly "what changed and why" report.
No jargon, no surprises. Here's exactly what working with me looks like.
We talk through your current setup, where you think the gaps are, and what revenue decisions you're currently unable to make confidently. No obligation, no sales pitch.
You receive a clear scope, timeline, and fixed price — no hourly surprises, no scope creep. Most quotes are delivered within a few hours of our call.
I do the work, keep you updated, and document everything so your team can maintain it — or I can monitor it for you on a retainer. You stay in the loop without being in the weeds.
Full documentation, a walkthrough call, and 30 days of follow-up support included in every project. Retainer clients get ongoing monitoring and a monthly insights report.

In developmentNot at all. I explain everything in plain language and handle all the technical work. Most of my clients are founders or marketing managers — not developers. I just need access to your GA4 property and tag manager, and I'll guide you through that step by step.
A data gap is anywhere your marketing data breaks before it reaches a revenue decision. Common examples: GA4 shows 500 conversions but your CRM only recorded 200 leads; your Google Ads reports a 3× ROAS but you can't verify it against actual sales; or half your traffic shows up as "direct" with no source. These gaps mean you're making budget decisions on incomplete information.
GA4 setup is the foundation — but it's only step one. Most businesses already have some tracking in place. My work goes further: connecting your analytics to your CRM, ad platforms, and revenue data so you can actually answer "which channels are generating profit?" rather than just "which channels are generating clicks?"
That's exactly what the Revenue Data Gap Audit is for. Most clients start there — it gives you a clear, prioritised picture of what's broken and what to fix first, without committing to a large project upfront. It typically pays for itself in the first week.
Yes. Every project includes 30 days of follow-up support. For teams who want continuous data quality assurance, I offer a monthly monitoring retainer — automated checks, tracking QA after releases, and a monthly insights report covering what changed, why it matters, and what to do about it.
It means you know exactly what you'll pay before we start. I scope the work carefully upfront, and if something unexpected comes up that's within the agreed scope, I absorb it — not you. If the scope genuinely needs to change, we discuss it openly before any additional work begins.
Answer a few quick questions and I'll send you a scoped quote — usually within a few hours.
