We worked with Jonathan to manage our Paid Search activity for Q4 2025. After auditing legacy setup & evolving both the paid ads setup alongside the conversion tracking, we saw a significant improvement in our core performance indicators Year over Year. Jonathan provided us with a greater transparency into our activity, complete with upskilling to be able to execute this in-house long term.

We commissioned Jonathan to perform an audit of multiple disparate websites from a Martech/Adtech perspective, then make recommendations about ideal future stack for a consolidated platform. Jonathan quickly got to grips with the brief, was proactive about engaging with the relevant stakeholders and ultimately presented back an audit report with exactly the right focus and level of detail. He clearly has detailed and up-to-date knowledge of the entire space, and we would certainly use Jonathan again for any similar consulting.
