How should pharma communications teams prepare for AI search?
Is AI search different from SEO?
Partly. Google says plainly that "there are no additional requirements to appear in AI Overviews or AI Mode, nor other special optimizations necessary"; the fundamentals of being findable still apply.
But ranking and being cited are not the same thing. When Ahrefs looked at which pages Google's AI Overviews cite, only 37.9% of the cited URLs also appeared in the first ten result blocks (which count ads and other search features alongside ordinary results); 31.2% came from blocks 11 to 100 and 31.0% from beyond the top 100. A page can be cited without ranking near the top.
The bigger difference is who is in the conversation. A person reading search results chooses which source to trust. A person reading an AI answer often receives one synthesized account, with the sources underneath. Whatever that answer says about your disease, your trial or your label is, for that reader, what is true.
What do answer engines tend to cite?
The evidence so far points to three patterns:
- Earned and third-party sources. A University of Toronto preprint found AI search weighted its results toward earned media in every category and region it tested; in US software-product queries, 72.7% of AI sources were earned media, against 45.4% on Google. Our inference for health: patient organizations, medical societies, journals and reporting are likely to carry weight that a brand page does not.
- Fresh pages. Seer Interactive, looking at citations to four brands across ChatGPT, Gemini and Perplexity from March to June 2026, found that 75% of the cited pages had been updated in the past year, and 88% in the past two. An undated or stale page is at a disadvantage.
- Professional voices. Semrush found LinkedIn was the second most cited domain in its data, appearing in 11% of AI responses on average across ChatGPT Search, Perplexity and Google AI Mode.
Does structured data (schema) help AI citations?
Not on current evidence. Ahrefs tracked 1,885 pages that added schema markup and found no citation lift on any platform it measured. Schema is good hygiene for search; it is not, on current evidence, how you earn an AI citation.
What should a pharma communications team do first?
We recommend a five-step cycle. It mirrors how a communications team already handles any important intermediary:
- Measure. Ask the main answer engines the questions your audiences actually ask, on a fixed date, and record the answers and the sources cited. Ask as a patient, a caregiver and a physician would: in Signal Fidelity Group's Disclosure Effect study, adding patient or caregiver context changed the cited sources past the study's threshold in 29.4% of eligible comparisons, and in 48.3% for one system. (The study is not peer reviewed and did not test medical accuracy.)
- Map the sources. List the pages each answer leans on. Which are accurate and current? Which are outdated, or describe your product as it was before approval?
- Publish an owned answer pack. Short, dated, plainly written answers to the most important questions, each citing the primary source: the label, the publication, the registry entry. A useful length is a short paragraph that can be lifted whole.
- Brief the explainers. Where an important third-party source is wrong or dated, the remedy is ordinary communications work: a correction request, a briefing, updated materials for the patient organization or society.
- Measure again. Re-run the same questions on a schedule and after every major event, and record what changed.
What is different for regulated communications?
Everything that applies to a press release applies to an answer pack:
- The label defines the claim. Approved indications should appear as the label states them. A broader paraphrase in an answer pack is the same problem as a broader paraphrase in a release.
- Investigational products stay investigational. A known drift pattern after an approval is an engine carrying forward investigational framing from before the decision. Decision days need an answer-engine check of their own; see How do you prepare communications for an FDA decision date?
- Fair balance still applies. An answer that lists benefits without the important safety information is not one your reviewers would approve on a page, and it should not be your page's answer either.
- Medical, legal and regulatory review still applies. An owned answer is a public statement and goes through the same review as any other.
What should you not do?
- Do not try to flood the engines. Publishing many near-identical pages is the opposite of what earns trust from people or machines, and in health it can look like promotion.
- Do not buy "guaranteed placement." No one controls what an answer engine says.
- Do not make search vocabulary the strategy. Keywords and markup are tools. The strategy is to be the clearest, best-sourced, most current account of the facts you are responsible for.
- Do not treat an AI answer as an endorsement. Being cited is not the same as being recommended, and saying so in marketing invites a correction.
How often should you check?
At least monthly for the questions that matter most, and on a tighter cycle around events. CommsRx's Phase 3 readout playbook, for example, schedules answer-engine checks at 24 hours, seven days and 30 days after the announcement.
How does CommsRx approach it?
CommsRx treats answer engines as trusted intermediaries, not an SEO channel. Its AI answer-surface playbook takes a team through the cycle above: a measured probe, a map of the sources the answers rely on, an owned answer pack that cites primary sources, outreach to the explainers that matter, and a re-probe. Answer-engine checks run in AI Pathways, and the drafts go through the same confirmed messages and review as everything else.
