About Timothy
I’ve spent over 15 years leading SEO strategy across agencies, universities, enterprise organizations, SaaS companies, e-commerce brands, and franchise systems. I hold a Master of Science in Marketing and have built my career at the intersection of search strategy, emerging technology, and measurable business growth.
My work sits at the forefront of where search is heading. As AI-powered platforms like ChatGPT, Gemini, and Perplexity reshape how buyers find information, I help brands build visibility across every platform that matters, not just Google. I was writing about generative engine optimization and AI search visibility before most agencies had added it to their vocabulary.
Every article I publish here comes directly from active client work. The strategies, frameworks, and recommendations you’ll find on this site are field-tested across hundreds of engagements, not pulled from industry reports or recycled best practices. If it’s here, it’s because I’ve seen it work.
