The Medic Update was a broad core algorithm update in August 2018 that disproportionately affected health, medical, and other YMYL websites, widely credited with bringing E-A-T (later E-E-A-T) into mainstream SEO industry awareness.
Many sites in medical and wellness niches experienced significant ranking volatility following this update, particularly those lacking clear author credentials, citations, or demonstrated expertise on sensitive health topics.
The Medic Update remains a frequently referenced case study illustrating why YMYL content requires meaningfully higher quality and credibility standards than lower-stakes topic areas.
We apply elevated quality standards for YMYL content within our SEO Content Strategy service.
