Leigh Merritt
Marketing & Digital Transformation Leader
There’s a pattern in my twenty-year career: I take fragmented, expensive digital operations and turn them into single, governed, measurably better ones — for Marsh McLennan, JLT, Aon and the Post Office. I don’t just advise, I implement: at enterprise scale, and most recently as a solo founder shipping a production SaaS platform built on AI-automated operations.
What I Do
I specialize in bridging the gap between marketing, technology, and business outcomes through:
- Website Analytics & Measurement
- SEO & AI-Driven Search Strategy
- Marketing Operations & AI Automation
With experience across a range of industries — from B2B Professional Services to consumer brands — I’ve supported business transformation, digital operations and campaigns that drove meaningful improvements in reach, engagement, and revenue.
Website Analytics & Measurement
I build robust analytics systems using tools like Google Analytics, Tag Manager, and Looker Studio to track user behaviour, conversion paths, and KPIs aligned to business outcomes. My focus is on turning data into insight, helping teams make smarter decisions about content, marketing, and product improvements.
SEO & AI-Driven Search Strategy
From technical audits to content strategy, I help brands increase their organic visibility and search performance. I stay ahead of AI-driven search trends to ensure your website remains discoverable in an evolving landscape — whether that’s Google, Bing, or emerging AI assistants.
Marketing Operations & AI Automation
I help marketing orgs streamline execution with automation and AI agents—building reliable workflows for reporting, content operations, QA, and campaign delivery that improve speed, consistency, and creative capacity.
