Dr. William Sen

Co-Founder & CEO

SEO Lead & Software Engineer

Dr. William Sen is the Co-Founder and CEO of Blue Media Marketing, Inc., the San Diego SEO agency he established in 2018. A software engineer with a Ph.D. in Information Sciences, he leads Blue Media’s SEO strategy and the technical side of its campaigns.

His career in digital marketing began in 1996, when he started offering web development and online marketing services to media houses, law firms, clinics, and construction businesses. In 2001 he added search engine optimization, then known as “web positioning,” making his company one of the earliest SEO agencies anywhere. Since then, he has provided SEO services to clients around the world.

Career & Background

Over the years, Dr. Sen has worked with major brands including BMW, Mercedes-Benz, Procter & Gamble, Ford, Bayer, PwC, T-Mobile, and Microsoft. In 2005 his company merged with a leading social listening provider, where he led software development and SEO marketing and helped take the company into the top five of its market within three years. That part of the business still operates in Germany today as infospeed.de.

Alongside his agency work, Dr. Sen spent 17 years as an Associate Professor at TH Köln, Germany’s largest university of applied sciences, teaching SEO, Digital Publishing, and Strategic Marketing. He is also a published author and journalist, wrote the first German Wikipedia article on search engine optimization, founded Germany’s first social media magazine, and organized the country’s first social media conference for seven years running.
