About Search Theory
Search Theory is an independent Manchester-based search marketing agency specialising in SEO, Digital PR and Paid Media. Our team build search strategies designed to drive visibility, authority and growth. Through SEO, Digital PR and Paid Media, we help brands increase their presence, outperform competitors and turn search into a real growth channel.
Founded by industry veterans David Vernon and Sara Kavanagh, we launched Search Theory to challenge outdated agency thinking. We move fast, stay curious and focus on strategies that create measurable impact, not vanity metrics or bloated reports.
Our approach combines technical expertise, creative thinking and data-led strategy to deliver campaigns that perform across every stage of the search journey. We put curiosity and a love of experimentation at the heart of our ethos.
We work as an extension of our clients’ teams, bringing transparency, momentum and honest thinking to every project. No fluff. No one-size-fits-all strategies. No AI-stuffed templates. Just search marketing built to send brands into the stratosphere. "
