About

I’m a Senior Technical SEO Consultant with 13+ years of experience across UK, US, Australian and South African markets, helping businesses turn complex search problems into clear, prioritised growth roadmaps.

My work covers technical SEO audits, crawlability, indexation, site architecture, Core Web Vitals, structured data, content strategy, analytics/reporting and AI/GEO search visibility. I’ve worked across agency leadership, technical consultancy and long-term growth strategy, often acting as the person brought in when SEO issues are unclear, messy or business-critical.

I help clients understand what is blocking organic growth, what to fix first and how to measure whether the work is moving the right commercial metrics.

Available for technical SEO audits, SEO strategy, analytics/reporting projects, AI search visibility reviews and fractional Head of SEO support.
