Top recommendations
- Enhance Content-Specific Schema (Schema Markup): Implement detailed Article and Person schema for the 'Stories' and 'News' sections to help LLMs attribute expertise to specific authors.
- Strengthen Author E-E-A-T Signals (Authority & Trust): Add explicit author bylines with links to professional credentials (e.g., LinkedIn or internal bios) for medical articles.
- Optimize AI Crawler Access (Technical Accessibility): Explicitly allow LLM-specific crawlers (GPTBot, ClaudeBot) in robots.txt to ensure full indexing of deep research pages.
- Formalize Entity Definitions via Schema (Entity Definition): Implement a dedicated 'Glossary' or 'Knowledge Base' schema to define complex medical terms for LLM training/retrieval.
- Improve Primary Source Attribution (Citation & Source Quality): Increase the use of outbound links to primary peer-reviewed studies (PubMed/DOI) within the 'Stories' and 'Science' articles.
