From SEO to GEO:

AI-first Search Strategy

Do you click on Google search results as much as you did a year ago? I certainly don’t. After your query on the search engine, the answer appears in front of you through Google AI. If I need greater detail or clarity, I usually use Google to open ChatGPT, Perplexity.ai, or even Gemini for web searches. I add a prompt, and in seconds, a wealth of information from potentially several authoritative sources is in front of my eyes. If I had clicked a Google link in the SERP (search engine results page), I would only get information from that particular site. And what I do now is becoming more common in searches than an exception. So, it would stand to reason that we need to make some adjustments to our websites, which were designed and configured to be more visible with the traditional paradigm.

Integrating AI SEO and GEO (Generative Engine Optimization) is now essential for life sciences businesses because buyers increasingly discover brands through AI-powered answer engines, and not just traditional search results. Teams that optimize for both are the ones whose assays, platforms, and services are displayed in answers and reap benefits in this discovery layer.

Over the next year, analysts estimate traditional search volume could drop by roughly 25%, with organic traffic for some categories falling by 50% or more as generative AI answers absorb queries that used to drive clicks. At the same time, more than three-quarters of life sciences and healthcare leaders now view AI as a primary driver of efficiency and growth, not a side experiment.^1,2 For CMOs, that combination means AI SEO and GEO are no longer “nice-to-have” pilots but core levers for sustained visibility for the pipeline in 2026 and beyond.³

The Shift To AI-Driven Search

AI and machine learning have transformed how search engines interpret intent, prioritize relevance, and generate answers instead of simple link lists. Generative engines like ChatGPT, Perplexity, and Google’s AI Overviews now synthesize responses from multiple sources, effectively becoming a new gatekeeper between your content and your buyers.

Brands that overlook AI-driven discovery risk losing visibility at the very start of the purchasing journey, when buyers are gathering information and identifying potential solutions without a preferred brand. At the same time, being cited by answer engines correlates with significantly higher engagement and conversion when users do click through.

What AI SEO Really Means Now

AI SEO is less about stuffing keywords and more about creating technically sound, intent-rich content that AI systems can easily interpret and trust. In life sciences, this includes structuring pages around precise scientific queries, using schema markup, and ensuring medical accuracy so models feel confident summarizing or citing your content.

AI-enabled tools now help life sciences marketers identify long-tail, high-intent keywords, uncover content gaps, and accelerate creation while maintaining compliance and scientific rigor. This matters because long-tail searches like “NGS-based MRD assay for adult ALL” instead of more generic “MRD test” tend to drive the most qualified traffic in niche scientific markets.

Example: Illumina dominates NGS-related searches by building topic clusters around core pillars like “CRISPR technology,” by linking pillar pages to 15+ supporting assets on applications, protocols, and case studies. This structure not only ranks them #1 for high-intent queries like “NGS MRD assay adult ALL” but also gets their content frequently cited in AI overviews, driving researchers directly to downloadable protocols and contact forms.^4,5

GEO: Optimizing For Answer Engines

Generative Engine Optimization focuses on how your brand appears inside AI-generated answers, not just on the SERP. Instead of only chasing a higher rank, GEO asks whether your content is structured, factual, and comprehensive enough to be selected, summarized, and cited by LLMs and answer engines.

Effective GEO emphasizes:

• Clear question–answer formats aligned to how clinicians, scientists, and procurement teams actually ask things.⁶
• Strong signals of authoritativeness (e.g., evidence summaries, references, and clear ownership) reduce hallucination risk and increase the likelihood of citation.
• Content clusters that explain a topic from multiple angles, such as clinical, technical, economics so AI systems can assemble responses for different job roles in the buying group.⁶

Example: A UK biotech firm restructured its whitepapers and case studies with question-answer formats and structured data around “biomarker validation workflows.” Following launch, their content became the primary source cited in Google AI summaries for clinician queries, increasing branded traffic by 40 percent despite low rankings, illustrating how GEO makes hidden expertise visible.⁷

Why Life Sciences Can’t Treat SEO And GEO Separately

Life sciences is already a high-intent, low-volume environment where every relevant visit and impression matters more than in broad B2C markets. As zero-click and AI-generated answers grow, a larger share of awareness and education will happen off-site, inside AI interfaces, where only a handful of brands get mentioned.

Brands that integrate AI SEO and GEO:

• Preserve discoverability in classic search by ranking in the top organic results that AI modes heavily draw from.
• Increase the odds that their content is the one answer engines select, which is already linked to higher engagement and conversion metrics versus traditional search visitors.
• Meet scientific buyers where they are-whether that is a Google query, an AI Overview, or chat-based research session-without rewriting strategy for each channel.
• Example: Thermo Fisher built authority by earning backlinks from NIH resources and journals through evidence-rich guides on “qPCR optimization.” AI engines now preferentially cite these in technical answers, preserving their visibility even as traditional clicks decline 25% industry wide.³

Practical Next Steps for Life Sciences Teams

Integrating AI SEO and GEO in life sciences starts with a strategic shift, not just new tools. Useful first moves include:

• Map real buyer questions by role (PI, lab manager, medical director, procurement) and turn them into structured, answer-first content hubs rather than generic product pages.
• Use AI-assisted keyword and content intelligence to prioritize topics where you can credibly be the “reference answer,” then build depth with data, real-world evidence (RWE), and clear scientific explanations.
• Add schema, FAQs, and citation-friendly formatting so generative engines can reliably extract definitions, comparisons, and stepwise explanations from your content.
• Treat off-page signals such as scientific backlinks, publications, and reputable mentions as fuel for both rankings and AI confidence in your brand’s authority.

As AI search accelerates, life sciences businesses that weave AI SEO and GEO into their digital strategy will capture an outsized share of attention from tightly defined, high-value audiences while slower competitors will fade into the background.⁶
