Dennis Interactive publishes around 20 magazines and 30 websites across motoring, technology, lifestyle, and current affairs verticals. They sell advertising solutions to clients through media agencies. Their key websites are a platform for advertising but are also user-centric. To make online advertising pay, Dennis focuses on delivering value to clients and agencies, developing relationships, always delivering on campaigns, using targeted but scaleable pricing, and diversifying their market segments. While CPM models are declining, the future may involve new models like cost per engagement, influence, or eyeball-minutes. Dennis will need to diversify but also manage large risks from premium solutions, user data harvesting, and demand side platforms.
