Google Ads


Hello, welcome to Den’s profile!

With a degree in Biotechnology and industry experience in DNA testing, Den is a Scientist by training. This naturally led him to develop a data-driven, evidence-based approach to testing new ideas and developing winning ad strategies.

Den has been advertising on Google since it launched in Beta back in 2000 and grandfathered on the 5¢ clicks for years. As the platform evolved, so did he – rigorously learning through various mastermind groups and by embracing the latest innovations. For him, the only way to consistently ‘win’ in paid advertising, or with anything in life for that matter, is to ‘always be improving.’
