Providing Digital Advertising Expertise since 2013
Welcome to my hub of all things digital advertising, spanning all things bought programmatically to more legacy mediums such as Paid Social & Paid Search. I am Jonathan, an experienced digital marketer based in London, UK with the core goal of providing transparency on key topics / trends within the digital ads ecosystem.
Simplifying the technical nuances
I pride myself of taking complicated topics across infrastructure, activation & measurement, making it easier to understand for all key stakeholders to make fundamental gains in your advertising strategy.
Cutting through the noise
The digital advertising ecosystem continuously evolves, bringing complexity alongside innovation. I hope to provide expertise through thought-leadership and education through my work on this website.
Doing the basics right
Attention to detail is critical in any form of digital advertising, whether this is campaign build, ad trafficking or infrastructure design. Those little checkboxes or settings are imperative to know about.
Keeping up to date
Monthly Digital Roundups summarises the key stories impacting the digital advertising ecosystem, with deepdives into the most important changes alongsides the latest updates in the search / social / programmatic / identity spaces.
