How I Work
Find the Constraint
Look at campaign performance, audience behavior, landing pages, and conversion tracking to identify the bottlenecks limiting results.
Build a Testable Plan
Identify opportunities to improve performance, develop a clear hypothesis, and test changes with a specific goal in mind. Use the results to learn what works and guide future optimizations.
Measure Business Impact
Evaluate performance using KPIs like conversion rate, cost per lead, lead quality, and customer acquisition. Use those results to understand what's working, what needs improvement, and where to focus next.
Connecting the Pieces
My experience goes beyond managing individual marketing channels. I've worked across paid search, local SEO, website development, landing pages, conversion tracking, reporting, and workflow improvement. Understanding how these pieces connect helps me identify opportunities, improve processes, and build marketing experiences that support measurable business results. More about me →
