What I do
The systems I build when growth depends on better signals, sharper creative, and cleaner conversion paths.
Full-Funnel Paid Acquisition
Paid programs tied to pipeline quality, creative velocity, and channel-level accountability.
SEO/AEO & AI-Search Visibility
Search visibility built for Google, answer engines, and LLM-led buyer discovery.
Website CRO & Experimentation
Testing programs that connect buyer psychology, offer clarity, and funnel conversion.
AI Agent Development for Marketing
AI workflows that compress research, briefing, QA, and creative production cycles.
Case studies
Two examples of diagnosing the system before scaling the spend.
Case study 01 · Measurement architecture
You don’t have a performance problem. You have a measurement problem.
Context: B2B SaaS demand-gen program with £1M+ quarterly media spend.
additional attributed revenue per quarter in a conservative Google Ads case — at the same spend.
39% closed-won unattributable
The audit found revenue that could not be tied back to a reliable source.
UTM drop at trial registration
A P0 tracking failure broke the handoff between acquisition and conversion data.
False 5.3× ROI signal
GA4 medium mislabelling was making the channel story look better than reality.
Insight
Broken signals were actively training bidding algorithms to under-invest in converting audiences.
Action
Built a 30/60/90 roadmap: cross-domain tracking fix, server-side UTM capture, Enhanced Conversions, LinkedIn + Meta CAPI, and channel reallocation.
Outcome
A configuration fix, not a budget increase: 15–30% CPA improvement across channels and clearer attributed revenue.
Case study 02 · Demand creation
New channels launched. Registrations hit a record high. The dashboards showed almost nothing.
Context: Q2 demand-creation push across 5 new channels and 9M+ impressions.
weekly sign-ups rose from 27 to 82 in 8 weeks while paid channels were still learning.
Problem
Awareness channels — display, audio, CTV, and video — received little direct attribution, with conversions absorbed into Organic Search after a 4–8 week lag.
Standout signal
Social-community remarketing hit <£100 CPA and 4.32% CVR — best in account.
Framework
Watch three signals: unattributed share shrinks, branded search grows, and “Other Referral” decomposes to reveal video ROI.
