What AI searched for first

Before it answers, it goes looking for Green Energy.

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 78 searches in energy suppliers, Green Energy is named in 50% 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.

Read is not cited

Octopus Energy converts reads into citations. ScottishPower doesn't.

When Claude or ChatGPT opens a brand's own pages while answering, does the page make the cited-sources list? Octopus Energy converts 67% of reads; ScottishPower just 0%. That gap is a content problem, not a visibility problem.

Which AI you ask

The models do not agree on who leads.

Ask about energy suppliers and the brand you are shown depends on the assistant: Claude → British Gas, Gemini → Octopus Energy, ChatGPT → Octopus Energy. Their top-five lists share just 25% of names.

What gets cited

Answer up front is what separates cited from ignored.

Of the energy suppliers pages models actually opened, how much more often each feature's pages ended up in the cited sources. Answer up front is worth 10 percentage points; cites its sources pages fare 46pp worse. Measured within the read population, so selection can't flatter it.

Citation readiness

EDF Energy 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. Ecotricity is the widest gap: well-built pages that still aren't converting into citations.

BrandReadinessPages citedPages profiled
EDF Energy 31 15% 59
Fuse Energy 29 47% 17
Octopus Energy 24 18% 68
Good Energy 24 40% 15
OVO Energy 24 20% 35
So Energy 24 20% 10
Ecotricity 20 0% 5
Outfox the Market 20 0% 5
British Gas 19 20% 60
Utility Warehouse 18 22% 9

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 energy suppliers 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 is a prepayment meter?
What is the energy price cap?
What is a smart meter?
What is a standing charge?
Why are standing charges so high?
What are time-of-use tariffs?
