Welcome back to HealthGEO Pulse.

Each month, we cut through the noise to bring you what actually matters in AI search and GEO, and what it means for pharmaceutical and healthcare brands.

Here’s what’s trending this month.

Gemini Gets Better at Thinking Through Complex Questions.

Google Blog, September 2026

Google announced new Gemini capabilities designed to improve how the model works through complex questions and multi-step problems. The update is part of a wider trend across the AI landscape as models become better at reasoning, adapting their responses and connecting information from multiple sources.

Most users won’t notice the technical details behind these improvements. What they’ll notice is that AI systems continue getting better at handling more nuanced questions, following complicated lines of thought and providing answers that feel more tailored to the context of the conversation.

In other words, the AI isn’t just getting better at finding information. It’s getting better at deciding what information matters.

For healthcare brands, that’s a meaningful shift. Success won’t only depend on whether information can be found. It will increasingly depend on whether information is clear, credible and connected to the broader sources AI systems use to understand a topic. As models become more sophisticated, the quality of the information ecosystem surrounding a brand becomes even more important.

OpenAI Connects Clinicians to Patient Records Inside ChatGPT.

Cloud Wars, September 9, 2026

OpenAI is connecting ChatGPT for Healthcare to Epic electronic health records, allowing clinicians to bring authorized patient information into ChatGPT and ask questions across appointment notes, lab results, medications and specialist documentation.

The move pushes conversational AI deeper into the clinical workflow. Instead of manually pulling together details before a visit, clinicians can use ChatGPT to identify what has changed since a patient’s last appointment, review recent labs, surface medication changes and prepare for follow-up conversations.

The part healthcare brands should pay attention to is how close AI is moving to patient records and clinical workflows. That makes the quality and accessibility of trusted information even more important. Labels, publications, guidelines, trial records and credible third-party sources may all help support accurate answers. The opportunity isn’t to influence the model directly. It’s to make accurate, current and credible evidence accessible when clinicians ask relevant questions.

AI Search Is Now Marketers’ Top Challenge, IAB Study Suggests.

Forbes, September 14, 2026

The marketing conversation around AI is shifting from how brands can use it internally to how they can reach people who are using it to make decisions. In the IAB study covered by Forbes, adapting to changing consumer behavior, including AI-driven search, was the top media-investment challenge for 44% of buyers.

Optimizing content for AI-generated answers was also the largest area of increased focus, cited by 76% of buyers. Measurement isn’t keeping pace. Buyers are changing how they evaluate performance, but many still struggle to connect AI-shaped journeys with the channels and metrics they already use.

That creates a measurement problem for healthcare brands. Patients, HCPs and other stakeholders may encounter information about a brand inside an AI-generated answer without visiting the source or entering a trackable website journey. That makes visibility, citation quality and answer accuracy important measures alongside traffic. It also means GEO can’t sit only with digital teams. Earned, medical, advocacy, corporate and owned content can all shape the information AI systems retrieve and use.

Correcting False Health Claims and Navigating AI-Generated Information.

KFF, September 14, 2026

KFF highlights two connected challenges for health communicators. Corrections can improve the accuracy of people’s beliefs, but their ability to limit further sharing may depend on reaching audiences before a false claim has already spread. At the same time, AI-generated search results may make people less likely to visit the original sources behind an answer.

That changes the relationship between publishing credible health information and receiving recognition or trust for it. An organization may contribute evidence that shapes an AI response without the user ever seeing its website, context or name. When inaccurate information moves faster than corrections, waiting to respond can also limit the impact of even a well-supported rebuttal.

The implication goes beyond fact-checking. Healthcare teams need to anticipate the questions and claims likely to emerge, publish clear evidence before information gaps are filled by weaker sources and monitor how AI systems summarize sensitive health topics. Success should include whether accurate information appears in the answer, whether trustworthy sources support it and whether the original context is preserved, not just whether someone clicks through to the original source.

Google DeepMind Develops New AI Search Ranking Model.

Search Engine Journal, September 10, 2026

Google DeepMind is testing a new approach that could give AI a larger role in deciding which information appears in search results. The research is still early and there’s no indication Google Search is adopting it today. But it offers a glimpse into where search could be headed.

Most users won’t notice the technical process happening behind the scenes. What they may eventually notice is a search experience that does a better job of understanding what they’re asking, evaluating the available information and deciding which sources are most useful.

In other words, the AI helping answer a question may also play a bigger role in deciding which sources are worth paying attention to.

For healthcare brands, that reinforces a broader trend we’ve been watching for some time. Success isn’t just about being technically discoverable. It’s also about making sure the right evidence, content and third-party sources are available to help shape how AI systems understand and represent a topic. That’s why SEO and GEO need to be planned together rather than treated as separate workstreams.

Your Questions, Answered

We want The HealthGEO Pulse to be a two-way conversation. Send us your GEO questions and we will tackle the best ones each month.

Q: How should we think about GEO if our audience isn’t using AI search at scale yet?

GEO doesn’t have to start with a large investment. It should start with understanding where AI already matters. Even if an audience isn’t actively using standalone tools like ChatGPT at scale, they may still encounter AI-generated answers through the search platforms and digital experiences they already use.

The right first step is to establish a focused baseline. Look at the questions that matter most to the audience, whether AI-generated answers appear around those questions, which sources shape them and whether the brand or its evidence is being represented accurately. That helps teams identify meaningful gaps without assuming they need to launch a large-scale GEO program from day one.

Audience adoption should inform the scale of the investment, not whether the brand should be paying attention at all. AI is already changing how information is found, summarized and understood. Starting with a targeted view of the highest-priority questions gives brands the evidence they need to decide where deeper action is warranted.
