Tom Petryk

Biography

Tom Petryk is the English publishing name used by Tomasz Pietrzyk, a digital strategist and web builder with more than 20 years of experience in digital marketing and web development. He has worked on hundreds of digital projects, including work for medical organisations, scientific communities and international businesses.

His current interests focus on how search engines and generative systems find, evaluate, retrieve and cite information. He studies the relationship between genuine subject expertise and the signals through which authority becomes visible: authorship, evidence, entity recognition, information architecture, distribution, mentions and citations.

He has a particular interest in organisations that publish medical and health information, where visibility must be balanced with accuracy, accountability and information safety. TomSEOTools does not provide medical advice.
