AI Visibility Research, Guides & Insights

TendorAI publishes evidence-led research and practical guides about how businesses appear in AI-generated answers. This page indexes measurement studies, AI visibility audits, cited-source research, structured data, buyer-intent visibility and practical guidance on the public information AI systems can find and use.

Our research separates what we measured from what we infer. Every card below is labelled with what it is — a measurement study, register analysis, a guide, an explainer or a comparison — so nothing has to be opened to find out whether it contains original measurement. Formal studies, with their panels and deviation logs, are indexed on Research.

Featured AI visibility research

A study is work with a pre-registered panel, a published deviations log and a downloadable dataset. TendorAI has four, and they are published in full and ungated at Research rather than here — this page indexes them so the distinction between a study and an explanation stays visible.

    Most UK Solicitors Are Never Recommended by AI. We Measured How Many.

    We tracked 1,214 SRA-regulated firms across 17 UK cities. 1,003 of them — 83% — were never named once. A handful were named in every single answer. AI visibility for solicitors is a threshold, not a ranking.

    The UK AI Visibility Report for Solicitors — July 2026

    US research says AI answers about lawyers are dominated by legal directories. We measured 12,279 citations across UK solicitor searches. The UK looks very different — and, for individual firms, harder to win.

    TendorAI

Each study names the assistants it used, the number of repeats and the collection window. The methodology sets out the shared method, and data & evidence covers what is published alongside each one.

Choosing an AI visibility audit

There is no industry standard defining what an AI visibility audit must contain, so two services with the same name can be very different products.

How TendorAI researches AI visibility

TendorAI measures how AI assistants respond to defined business and buyer questions. For paid measurements, questions are repeated across multiple runs so conclusions rest on a body of recorded answers rather than a single response.

  1. Understand

    The business, its services, its markets and the questions its buyers ask.

  2. Measure

    Run the defined questions across the agreed assistants, repeating each one.

  3. Evidence

    Keep the recorded answers and the sources cited in them.

  4. Find

    Identify patterns and gaps that warrant investigation.

  5. Act

    Agree and implement what the evidence justifies changing.

  6. Remeasure

    Repeat the same questions by the same method, later.

  7. Compare

    Set the new observations against the recorded baseline.

  8. Report

    Say what changed, what did not, and what follows.

Measurement records what happened

A measurement is a record of how assistants answered a defined set of questions, in a stated window. It is not an explanation.

Evidence supports findings

A finding should be traceable back to the recorded answers and cited sources behind it, not asserted on its own.

A finding is not proof of cause

Two measurements can be reported side by side. The causal link between a change and a later result is not measured, and TendorAI does not claim it.

Remeasurement compares against a recorded baseline using the same questions and the same method. The methodology page lists what this design can and cannot establish, and how it works walks through the same sequence from a customer’s side.

What does TendorAI mean by AI visibility?

AI visibility describes how a business appears when people use AI assistants and AI search to research providers, services and buying decisions.

TendorAI examines different observable states rather than treating every appearance as the same. These three are the ones its measurement records and its reports distinguish. They are not stages of a funnel: a business can be cited without being recommended, or recommended without being cited.

Mentioned
The business is named in the answer. Being named is not the same as being recommended.
Cited
A source is referenced in the answer. A citation is evidence that a source appeared — not evidence that it influenced the answer.
Recommended
The business is put forward as an option the reader might choose. This is the state buyers act on.

Measurement is not the same as diagnosis

Measurement asks: what happened?

A defined set of buyer questions, put to AI assistants and repeated, with the answers and the sources cited in them recorded. It establishes the pattern. It does not explain it.

AI Visibility Benchmark

Diagnosis asks: why might this be happening?

Investigation of the recorded evidence — what is missing, what is unclear, what the cited sources show — to work out what deserves attention and in what order.

AI Visibility Audit

Acting on a diagnosis, measuring again and comparing against the baseline is AI Visibility Growth. Prices for all three are on the pricing page.

Guides, explainers and comparisons

Guidance, explanation and comparison. None of these is a measurement study; each card says which it is.

Industry and city analysis

Analysis built from public register records — SRA, ICAEW, FCA and Propertymark — covering what businesses in a sector and city publish about themselves. These are not measurement studies: they have no prompt panel and no deviations log, which is why Research does not list them as studies either.

Free tools

Free checks that answer one question each. None of them measures what AI assistants say — that is a different exercise, described above.

All of them are listed on the free AI visibility tools page.

The free AI Visibility Report records how supported AI systems currently represent your business. If the evidence warrants going further, the Benchmark establishes a repeated baseline and the Audit investigates what the evidence supports.
