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.
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.
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.

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 this library is labelled, and how to browse it
Every card is labelled with what it is. Each topic below goes to a section of this page or to the page that covers it — there are no thin index pages behind these links.
Original research
A TendorAI measurement study with a published panel, a deviations log and a downloadable dataset.
Industry analysis
Analysis built from public register records for a sector or city. Not a measurement study.
Guide
Practical instructions for doing something.
Explainer
Explains a concept or answers a question. No original measurement.
Comparison
Compares named providers, products or approaches against stated criteria.
Methodology
Describes how TendorAI measures, and what a measurement can and cannot establish.
Start with TendorAI’s free AI Visibility Report to see how supported AI systems currently represent your business. It is a starting point, not a measurement study — the difference is explained below.
Free, with no payment details. The free AI visibility tools check individual things — structured data, crawler access, readiness.
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.
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.

A website change has not improved your AI visibility simply because the page was updated or indexed. Testing it needs a recorded baseline, frozen buyer questions, repeated runs and a second measurement using the same method — and care about what the comparison can prove.
Before ChatGPT, Claude or Perplexity recommends an accountant, it has to work out which firms are genuinely chartered and ICAEW-registered. Where your website and the ICAEW record disagree, the assistant hedges or leaves you out. Here is how that check works and how to pass it.
Before ChatGPT, Claude or Perplexity names a UK solicitor, it has to confirm the firm is genuinely SRA-regulated. Where your website and the SRA register disagree, the assistant hedges or leaves you out. Here is how that check works and how to pass it.
A UK judge has referred solicitors to the SRA for submitting AI-generated legal citations that did not exist. Here is what it signals for AI visibility, trust, and authority in 2026.
A step-by-step guide for UK solicitors on getting recommended by ChatGPT, Perplexity and Google AI Overviews. Covers schema, regulatory data, and AI visibility strategy.

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.
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.
