Best LLM monitoring for pharma marketing: how we approach it
How we approach LLM monitoring for pharma marketing: tracking what AI says by country, which sources it uses, crawler access, and where human review stays in charge.
Pharma is the sector where we are most careful about what monitoring promises. Patients and healthcare professionals ask AI engines about conditions, treatments and brands, and the answers mix sources a company does not control. LLM monitoring gives marketing teams a record of what those answers say. It does not tell them whether a statement is accurate or compliant. That is a job for medical, legal and regulatory colleagues, and we say so at the start of every conversation.
Nothing here is regulatory advice. We use Promptwatch for monitoring on client programs, and we claim only what its documentation supports: ISO/IEC 27001 certification and GDPR compliance. We do not claim anything about pharma rules.
What we set out to learn
When we scope a monitoring program for a pharma brand, the questions are modest and useful:
- What do AI engines say about the brand, its competitors and the condition area?
- Which sources do they draw on, and are any of them the company's official pages?
- How does the picture differ by country?
- Can AI crawlers reach the approved content at all?
- What changes from month to month?
Building the prompt panel
We write prompts the way each audience would ask, without leading the engine.
- Patients: "what are the treatment options for [condition]," "what are common side effects of [class]," "[brand] vs [competitor]."
- HCPs: "how does [brand] compare with [competitor] for [indication]."
- Brand: "is [brand] safe," "who makes [brand]," "does [brand] have a patient support program."
- Per market: the same prompts in each country, because availability and labeling differ.
Prompt Explorer suggests prompts from Search Console, ranking keywords and People Also Ask. We tag them by topic and type and add personas to see how answers shift between patient and professional askers.
Reading the answers
Monitors run daily per model, country and language. Each response gets a Sentiment score from 1 to 100, with a weekly AI summary, and we track Position in Answer, Share of Voice and Visibility Score. The Brand Book is worth the setup time here. Its analysis instructions and brand aliases decide how brand names, generic names and product lines are counted, which keeps the data consistent when a product has several names.
We read samples of the responses by hand. A tone score points to where to look, and then a human reads it.
Finding where it came from
The most useful finding is often a source. Citation analytics shows page and domain level citations and URL positions, so we can see whether an engine quoted an official page, a patient forum or a news article. Reddit, YouTube and LinkedIn reports cover community and video sources, and offsite mentions show where the brand is named without a link. We pass those source lists to the client's content and medical teams. What to do about them is their decision.
Checking access
Agent Analytics shows IP-verified visits from real agents including GPTBot, OAI-SearchBot, ChatGPT-User, ClaudeBot and PerplexityBot, with failure explanations. If approved pages are blocked by a firewall rule or CDN setting, engines fall back on other sources. Crawler logs start on the Professional plan ($245/mo). Essential does not include them.
Governance and reporting
Promptwatch has owner, editor and viewer roles, scoped API keys and an audit log on Business and higher. SSO is on Enterprise. PDF reports of any dashboard, scheduled PDF reports and CSV or Excel exports give regulatory and brand colleagues something concrete to review. Slack briefings exist but are not available on white-label workspaces.
Where we keep humans in charge
- Content. The Content Agent (Business and Enterprise) has a review inbox. For pharma, anything generated goes into the client's own medical, legal and regulatory review before use. We would not run it hands-off here.
- Interpretation. Whether an answer is on-label or acceptable is not something monitoring can decide.
- Sampling. A tracked panel is a sample. Answers vary between runs, so we read trends over weeks and keep a monthly manual check.
Plans, briefly
Essential is $95/mo, Professional $245/mo, Business $579/mo. Agency Kick-off, Growth and Scale are $199, $399 and $799/mo, with country, state and city tracking and crawler logs on every agency plan. For global brands, Enterprise is tailored.
Other tools clients ask about
Large pharma procurement teams often ask about enterprise-only vendors such as Profound, Brandlight and Evertune, which are sold through sales with custom or unpublished pricing. AthenaHQ and Scrunch AI are also common shortlist names. They are credible products. We chose Promptwatch because the sources, crawler access and sentiment sit alongside the monitoring, which is what a regulated team needs for a documented picture.
What we tell clients a pilot should produce
One brand, one competitor, 20 to 30 prompts, two countries, one month. The deliverable is a documented picture: what engines said, which sources they used and whether approved content was reachable. It is not a promise that engines will change what they say.
