Client Profile: API & Custom Synthesis Manufacturer (B2B)
Timeline: April 2024 – July 2025
In the highly regulated pharmaceutical industry, trust is a critical ranking factor. Our client, a mid-sized CDMO specializing in APIs, possessed world-class manufacturing capabilities but lacked the digital authority to match.
Despite having high-quality products, their website was failing to connect with Googlebot. Upon audit, we identified two primary bottlenecks:
Our objective was to restructure the site into an authoritative chemical database, proving to search engines that this data was verified, accurate, and expert-backed.
Consolidating the Molecule Library
The site previously treated chemical variants (e.g., different pack sizes or purity grades) as separate pages, which diluted ranking potential. We reorganized the catalog into a unified structure. Instead of having five weak pages for one compound, we consolidated them into single master product pages. These now centrally house the CAS number, IUPAC name, and therapeutic applications, effectively eliminating keyword cannibalization.
Establishing E-E-A-T & Data Integrity
To overcome the YMYL barrier, we overhauled the About Us and author sections, explicitly linking internal PhD scientists to their published research. Crucially, we validated product data by adding outbound citations to authoritative databases (like PubChem and FDA.gov) directly on product pages. This signals to algorithms that our chemical specifications are rigorous and verified.
Targeting Technical Intent
High-value buyers search for specifications, not just names. We expanded on-page content to target specific long-tail technical queries, such as "impurity profiles" or "custom synthesis timelines." We also deployed ChemicalSubstance schema markup, helping Google understand the structured data behind the text.
The GSC data from the 16-month engagement illustrates a clear sanitize and scale trajectory.
The Weekday Pattern
The graph displays a distinct sawtooth pattern—high traffic on weekdays, dropping on weekends. This confirms we are successfully reaching a professional B2B audience during laboratory and office hours, rather than casual weekend browsers.
