What AI wants here

Ibuprofen is named most. That is not the same as being wanted.

Being named is visibility. Underneath it, asked to rate each brand directly, the AI assistants judge it three ways — how much it stands out, how much it belongs, and how much it is returned to. They put 25% of the 40 brands rated above indifference. Boots leads the brands the answers name, at 76% of maximum Desire. On attraction, the most divided driver, Boots indexes 132 against Midrid at 69, on a category average of 100.

Each whorl lights one ring per index threshold cleared (84 / 92 / 100 / 108 / 116). Above indifference means Desire above two-thirds of its maximum. See the full pain relief desire edition →

What AI searched for first

Before it answers, it goes looking for Ibuprofen.

An assistant does not answer from memory alone. It runs its own web searches first, and whoever it searches for is the shortlist it then chooses from. Across 87 searches in pain relief, Ibuprofen is named in 52% of the ones that name a brand at all. ChatGPT Web, Copilot do not report their searches, so these shares are measured against the ones that do.

Who AI trusts here

The referees of pain relief.

The independent sources AI models cite when answering pain relief questions — the places a brand needs to be seen, reviewed and ranked.

Read is not cited

The citation gap.

When Claude or ChatGPT opens a brand's own pages while answering, does the page make the cited-sources list? Too little read data in this category so far — the weekly runs will fill this in.

What gets cited

Structured data is what separates cited from ignored.

Of the pain relief pages models actually opened, how much more often each feature's pages ended up in the cited sources. Structured data is worth 20 percentage points; hard statistics pages fare 8pp worse. Measured within the read population, so selection can't flatter it.

Citation readiness

Calpol builds pages AI can quote.

Readiness scores each brand's own pages on the structure models reward — a direct answer up front, tables, hard numbers, named authors, structured data, recency, specifications. Calpol is the widest gap: well-built pages that still aren't converting into citations.

BrandReadinessPages citedPages profiled
Calpol 47 0% 25
Solpadeine 44 0% 25
Superdrug 34 25% 4
Voltarol 34 6% 70
Asda 33 0% 3
Nurofen 32 5% 132
Advil 25 0% 4
Anadin 25 0% 25
Tesco 21 0% 3
Well 19 1% 127

Readiness is the share of eight measurable structural signals present on a brand's profiled pages. It is a build-quality measure, not a ranking of the brand.

What the answers answer

The questions pain relief pages have to settle.

Read straight off the pages AI cited: the consumer questions cited content answers most often. Content that fails to settle these is content models have no reason to quote.

What causes tension headaches?
What is a muscle strain?
What is paracetamol used for?
What are the common side effects of NSAIDs?
What does RICE stand for?
When should you call 999 or go to A&E for a headache?
