By model

How each assistant handled Pharmaceutical SEO Case Study questions.

Reading the 120 answers model by model shows how differently the three assistants treat the same pharmaceutical seo case study questions. On the most consequential behavior — whether to send the buyer to a professional at all — the rate ranged from 27.5% (ChatGPT) down to 15% (Gemini), a 13-point gap on an identical question set.

Across the 40 pharmaceutical seo case study answers it produced, ChatGPT recommended hiring a professional in 27.5% of them and suggested a DIY approach first 30% of the time. It named a specific provider in 2.5% of answers (about 0.1 distinct providers per answer) and included price or cost information 7.5% of the time. ChatGPT asked a clarifying question before answering in 37.5% of cases, warned about red flags or scams in 12.5%, and told the buyer to verify credentials in 12.5%, averaging 784 words per answer. On the remaining cues it told the buyer to check reviews in 2.5%, pointed to case studies or a portfolio in 22.5%, and framed the choice around local proximity in 0%; a selection-criteria checklist appeared in 30% of its answers and a recommendation to gather multiple quotes in 0%.

Across the 40 pharmaceutical seo case study answers it produced, Claude recommended hiring a professional in 20% of them and suggested a DIY approach first 2.5% of the time.

Taken together, ChatGPT is the assistant most likely to route a pharmaceutical seo case study buyer to a professional (27.5%) and Gemini the least (15%). ChatGPT produced the longest answers, at 784 words on average. Specific providers were named most often by Claude (15%) — even there, roughly one answer in 7 carried a name.

Where they disagree

The behaviors where the choice of model changes the answer.

The divergence index for this study is 16 points — the average distance between the most and least likely model across the coded behaviors. The gaps below are where which assistant a pharmaceutical seo case study buyer happens to ask matters most:

  • Asks a clarifying question: from 0% (Gemini) to 50% (Claude) — a 50-point spread.
  • Suggests a DIY approach first: from 2.5% (Claude) to 30% (ChatGPT) — a 28-point spread.
  • Names a specific provider: from 0% (Gemini) to 15% (Claude) — a 15-point spread.
  • Mentions case studies or portfolio: from 22.5% (ChatGPT) to 37.5% (Claude) — a 15-point spread.
  • Recommends hiring a professional: from 15% (Gemini) to 27.5% (ChatGPT) — a 13-point spread.

The widest single gap — asks a clarifying question, 50 points — means a pharmaceutical seo case study buyer can receive materially different guidance on the same question depending only on which assistant they happen to open, so any visibility strategy built on a single model's behavior describes only part of the pharmaceutical seo case study market.

Where they agree

  • Tells the buyer to check reviews: 0%–5% across all three (a 5-point spread).
  • Tells the buyer to verify credentials: 7.5%–12.5% across all three (a 5-point spread).

Measured question by question, the three assistants coded a response the same way most consistently on "recommends multiple quotes" (identical coding in 97.5% of questions) and least consistently on "asks a clarifying question" (37.5%).

Trust signals

How well the models protect the pharmaceutical seo case study buyer.

Beyond whether to hire, the rubric codes how carefully each assistant protects the pharmaceutical seo case study buyer once a decision is made. Telling the buyer to check reviews or ratings appeared in 2.5% of answers on average. Verifying credentials or certifications appeared in 10%. Warning about red flags or scams appeared in 16.7%.

On structuring the decision, a selection-criteria checklist showed up in 30.8% of answers on average and a recommendation to gather multiple quotes in 0.8%. The single least-reproduced protective signal for pharmaceutical seo case study is "recommends multiple quotes" at 0.8% on average — the clearest opening for content that supplies it, since the models are not yet reliably surfacing that guidance on their own.

Referral behavior

Do AI models name Pharmaceutical SEO Case Study providers?

For service providers the decisive question is whether these systems name anyone at all. Across 120 pharmaceutical seo case study answers, a specific provider was named in 5.8% of responses on average — roughly 0.2 distinct providers per answer. In practice the assistants behave far more as an explanatory layer than as a referral engine for pharmaceutical seo case study: visibility comes from being the reasoning a model reproduces, not from being the named recommendation.

The question set

The 40 questions behind every percentage on this page were drawn from real pharmaceutical seo case study (healthcare services; buyer hiring decisions for this specific service) buyer journeys. Each was put to all 3 models once, with identical wording, so the rates above describe how the assistants handled this exact pharmaceutical seo case study question set — not a general prior or a hand-picked subset.

How to read this

A note on the numbers.

A percentage here is the share of a model's 40 answers in which the behavior appeared at least once — not a confidence score. Because each model answered every question exactly once on 2026-07-06, the figures describe this specific pharmaceutical seo case study question set and snapshot rather than a general prior. The full protocol and coding rubric are documented in the study methodology.
