The Challenge

The Procalcitonin (PCT) testing pages represent one of Thermo Fisher Scientific's most impactful educational hubs—providing critical insights into antibiotic stewardship, bacterial infection diagnostics, and cost-effective care strategies. Yet despite the scientific importance and market relevance of the content, the pages were underperforming in organic search visibility, struggling to:

  • Rank for high-value search terms like "procalcitonin test," "PCT in antibiotic stewardship," or "economic impact of PCT use"
  • Surface in rich SERP features like Featured Snippets or People Also Ask
  • Drive qualified traffic to core conversion paths like contact forms and learning center content

That's where On Beat Digital came in—armed with SatelliteAI, our proprietary, AI-powered SEO and predictive intelligence platform.

Our Solution
