SEO Case Study: Building Topical Authority on a New Biotech & Pharma Marketing Website

Most SEO projects are executed on aged domains with existing authority and backlinks. Deepli wanted to demonstrate the existing SEO methodology on a fresh domain such as biotechpharmamarketing.com, which had no previous authority or backlinks built.

Between May and August 2026, we implemented a topical authority strategy on biotechpharmamarketing.com domain focused on biotech, pharmaceutical, CRO/CDMO, diagnostics, and life science marketing.

The implementation included:

• 17 service pages
• 13 solution pages
• 9 case studies
• 6 blog articles
• Additional supporting pages and internal linking architecture

Total new pages published: 48


Pages were published gradually rather than all at once. New content was added continuously from mid-May through early August, allowing Google to crawl and index the expanding content cluster. Importantly, the project was intentionally launched on a new domain to prove that our methodology can work within several months from scratch even on a website that has no strong off-page SEO (backlinks) built yet, however can already generate inbound leads through content.

As Google Search Console shows the website after less than 3 months of content publishing shown over 19,000 impressions, generating over 500 impressions per day, while before content publishing it was a flat line with no impressions. On a first week of new content released (approximately 2-4 pages per week), the average position of website pages was 46 (Page 5 in Google), while after less than 3 months of content publishing the average position moved to 27 (Page 3). The website started to rank on 460+ non-branded queries, and produced 39 organic clicks, of which multiple led to high-quality inbound inquiries.

One notable observation was that impressions continued to grow rapidly while new content was being published. Between July 1st and 16th, when no additional pages were added, impression growth began to stagnate, suggesting that continuous publication on new search queries was a significant growth driver during the early phase.

The average session duration was below 20s before implementation of SEO-optimized pages, while after implementation became over 3 minutes, with some days peaking 16 minutes (see screenshot from Google Analytics above) as new interesting content was added. The organic traffic increased 6X over the course of less than 3 months.

This case study demonstrates that a structured topical authority strategy can produce measurable SEO growth on a new life science website within a relatively short period. By publishing targeted service pages, solution pages, case studies, and supporting content around a focused niche, we increased the number of ranking queries from 6 to more than 460 and improved search visibility from average position 46 to position 27 in less than three months, generating over 19,000 impressions and multiple inbound inquiries. For biotech, pharmaceutical, CRO/CDMO, and life science companies, the results suggest that consistent publication, industry-specific content clusters, and strong internal linking can create significant early SEO momentum even before substantial backlink acquisition begins.
