Medical and Health Website Image SEO: Best Practices and Examples

Health and medical websites fall under Google's YMYL (Your Money or Your Life) category — meaning Google holds them to higher quality standards. Image SEO on health sites must balance SEO goals with accuracy, sensitivity, and patient privacy requirements.

Medical Image Alt Text Principles

• Accuracy first: Alt text must be medically accurate — not marketing language
• Sensitivity: Describe clinical content professionally and with appropriate sensitivity
• Privacy: Never include patient names or identifying information in alt text
• Clarity: Use plain language where possible for accessibility

YMYL Image SEO Considerations

On YMYL health pages, image quality signals matter more than on other topics because Google's Quality Raters specifically look for E-E-A-T (Experience, Expertise, Authoritativeness, Trustworthiness). Professional photography — not stock photos — demonstrates this better. If using stock photos, choose clinical, realistic imagery rather than overly staged or unrealistic depictions.

Patient Consent and Image Rights

Any images featuring real patients require documented consent. For dental, cosmetic, or surgical before/after photos, maintain signed consent records and include alt text that clearly labels them as clinical case photos without identifying the patient.
