Jesper Nissen is an SEO expert, software engineer, and entrepreneur known for applying a scientific, test-driven approach to search engine optimization.

With a Master’s degree in Theoretical Physics from the Niels Bohr Institute at the University of Copenhagen, Jesper brings the same curiosity and analytical thinking he developed in science into SEO. He has more than 17 years of experience across software testing, systems design, software engineering, web development, and search.

Jesper is the founder of YACSS, a platform for building and distributing websites across cloud platforms, and SchemaWriter.ai, an AI-powered platform for generating structured data, entities, and optimized schema markup.

His work focuses heavily on technical SEO, link building, indexing, entity optimization, automation, cloud-based SEO strategies, and experimentation. Rather than relying on theory alone, Jesper continuously tests how search engines respond to different tactics and shares those findings through his content, training, and speaking.

He is also known for exploring unconventional strategies such as parasite SEO using platforms including YouTube and Reddit, making his work particularly relevant to practitioners operating in highly competitive search environments.

As an international speaker and educator, Jesper brings a rare combination of scientific thinking, software expertise, and hands-on SEO experimentation, giving audiences practical insights into what is working in search right now.
