Turning a Client Interview into a Case Study

- Say on the recording that you are recording; it settles the question in every state.
- Claims purporting to be based on any fact can be required to be evidenced, up to a year later.
- Consent to be interviewed is not consent to advertise; ask for the second in writing.
- Publish a transcript alongside any audio, for access, for search and as your own record.
- Keep one folder per piece: consent, permission, dates, audio, transcript, sources.
A case study is advertising that purports to be based on fact, which puts it in a category with two obligations attached: the interview has to be recorded lawfully, and the claims in it have to be provable a year later by somebody who was not there.
Neither is difficult. Both are invisible until somebody asks, and by then the client has gone home and the recording is on a phone that was replaced.
Recording the conversation
The federal position is permissive and the state positions are not uniform, which is the whole of what a guide needs to know.
Federally, it is not unlawful for a person not acting under colour of law to intercept a wire, oral or electronic communication where that person is a party to the communication, or where one of the parties has given prior consent, unless the interception is for the purpose of committing a criminal or tortious act.
Read the structure rather than the relief. It permits recording a conversation you are part of. It does not displace stricter state rules, several of which require every party to consent, and it carves out recordings made for a wrongful purpose.
The workable practice is therefore the same everywhere, which is to ask on the recording. Start it, say that you are recording and what it is for, and let them answer. Ten seconds of audio settles the question permanently and costs nothing, and it is the only version that survives moving states, changing phones and forgetting.
Everything else a guide does to be found sits at the getting-booked hub.

What you can be asked to prove
The part guides never anticipate. California's provision makes it unlawful for a business advertising to consumers there to make any false or misleading advertising claim, including claims that purport to be based on factual or objective evidence, that compare effectiveness to other products, or that purport to be based on any fact.
Then the mechanism. On written request of the Director of Consumer Affairs, the Attorney General, or a city attorney, county counsel or district attorney, a business on whose behalf such claims are made must provide evidence of the facts on which the claims are based. The request must be made within one year of the last day on which the claims were made.
A case study is exactly a claim purporting to be based on fact. It names a client, describes a day, and states an outcome. Every one of those elements is something you could be asked to evidence, and the request can arrive up to a year after you last showed the page.
What that means in practice is a folder rather than a lawyer: the signed permission, the recording, the date, and whatever supports any number the piece contains.
What a case study should actually claim
The safest version is also the most persuasive, which is unusual and worth exploiting.
Claim what happened, dated, to a named person, in stated conditions. Somebody caught their first permit on a difficult day in June is a fact about a day. Somebody will catch their first permit is a promise, and it is the promise that creates both the obligation and the disappointment.
Avoid comparisons with other operations entirely. The provision names comparative claims specifically, and in a small market a comparison is also a fight you gain nothing by starting.
Avoid aggregates unless you actually counted. Most clients catch fish is a claim about a population you have never measured, and it is the kind of sentence that reads as harmless until somebody asks for the evidence.
And avoid implying that the described day is typical when it was not, which is the same discipline a fishing report needs, set out in the fishing reports piece.
The interview itself
Twenty minutes, six questions, recorded, and the whole thing works better on the phone a week after the trip than at the dock.
At the dock somebody is tired, wet and being polite. A week later they have told the story twice to other people and know which parts are interesting, which is also why a recorded conversation works better with a little distance from the event, which is exactly the material a case study needs.
The six questions that produce usable answers: what made you decide to book, what were you worried about beforehand, what actually happened on the day, what surprised you, what would you tell somebody considering it, and is there anything you would change. The fourth and the sixth produce everything worth quoting.
Ask, then stop talking. The useful sentence almost always arrives after a silence somebody else fills, and guides ruin more interviews by helping than by any other means.
What to keep, and for how long
| Item | Why |
|---|---|
| Recorded consent to record | Settles the recording question permanently |
| Written permission to publish | Consent to speak is not consent to advertise |
| The date of the trip and interview | Every claim is a claim about a day |
| The raw audio | Evidence of what was actually said |
| Support for any number used | Claims purporting to be based on fact |
| All of it, for over a year | A request may arrive within one year of last use |
Permission is two separate things
Agreeing to be recorded is not agreeing to appear in your advertising, and the second permission has to be asked for in its own words.
Ask in writing, after the interview, naming what you intend to publish: their first name or full name, the water, the date, quoted sentences, and any photograph. Give them the option of a first name only, which most people take and which costs the piece nothing.
Send them the finished piece before it goes up. Nobody has ever objected to being shown a draft, and the small corrections they offer usually improve it. That courtesy is also the thing that makes people say yes to the next request.
Photographs carry their own permission question, and the mechanics of asking well are in the photo permission piece.
Publishing it so it can be read
If any of the interview is published as audio or video, a transcript is not optional in practice.
Federal accessibility guidance describes captions and transcripts as tools that provide access to audio content, with captions describing dialogue, music and sound effects in video, and transcripts describing audio-only and video-only content such as podcasts.
Two reasons to do it beyond the obvious one. A transcript is text on a page, which is the only part of an audio file a search engine can read, and a case study that exists only as audio is a case study nobody finds. And a transcript is your record of what was actually said, which is the evidence the substantiation question eventually asks for.
Publish the transcript alongside rather than instead. People who want the voice get the voice; people skimming get the sentence they were looking for.
Structuring the piece
Five parts, in this order, and the order matters more than the prose.
Who they were and what they wanted, in two sentences. Somebody a reader can recognise as themselves is what makes the rest land.
What they were worried about. This is the part every guide omits and every reader is looking for, because the worry is why they have not booked yet.
What happened, dated and specific, including the conditions. Not a highlight reel; a day.
What changed, in their words. One or two sentences quoted exactly, chosen because they are specific rather than because they are flattering.
And what a reader should do, plainly, once. A case study that ends without a next step has done all the work and stopped short.
Choosing who to ask
The best case study is rarely the best day, and guides pick wrong by instinct.
The client who caught the most fish produces a piece about fish. The client who arrived nervous, had a difficult morning and left having learned something produces a piece about the thing readers are actually deciding, which is whether they will be looked after.
Look for somebody who resembles the client you want more of. A retired couple, a parent with a teenager, somebody who had not fished in twenty years. A reader recognises themselves or they do not, and recognition is most of the persuasion.
Ask people who have booked twice, because the second booking is itself evidence and because they know you well enough to be candid.
And ask soon. The willingness to be interviewed decays quickly, and somebody three seasons removed remembers a version of the day that has been polished by retelling.
Getting real answers
Most interviews fail in the first two minutes, when the guide asks whether the client enjoyed it and the client says yes.
Ask about the decision rather than the day. How did you choose, what else did you look at, what made you pick this one. Those answers describe your market and are the most commercially useful part of the whole exercise, quite apart from the piece, and they feed straight into the pages people arrive on.
Ask for the moment rather than the summary. Not was it good, but what was happening when it changed. People answer that question with a scene, and scenes are what get quoted.
Ask what they told other people afterwards. That is the version already tested on a real audience, and it is usually better than anything they say to you directly.
And ask the negative honestly: what would you change. A piece containing one small criticism is dramatically more credible than one containing none, and the criticism is nearly always something you can fix.

Writing it without over-writing it
The failure mode is a guide writing a piece of marketing around three quotations. The version that works is closer to reporting.
Keep your own voice out of the client's part entirely. Their words, their rhythm, their hesitations. If a sentence needs trimming for length, trim from the ends rather than the middle, and never join two separate answers into one quotation.
Use short quotations frequently rather than one long block, because a page of unbroken quotation is skipped and a sentence in the middle of your own paragraph is read.
Keep the whole piece under about eight hundred words. A case study is read by somebody deciding, not by somebody studying, and length reads as a lack of confidence in the material.
And date it visibly. An undated case study is assumed to be old, and an old one is assumed to be the best you have ever managed.
What experienced guides do differently
They ask the awkward question. What nearly stopped you booking is the most valuable sentence in the whole interview, and nobody volunteers it.
They quote exactly, including the hesitation. Cleaned-up quotations read as invented, and readers who fish are good at spotting a client who has been rewritten.
They publish few and update them. Three real case studies, dated and kept current, outperform twelve thin ones, and thin ones age badly.
And they treat the interview as a relationship rather than an extraction. Somebody who was asked thoughtfully about their day usually books again, which is worth more than the page, and which is the same argument made in the video testimonial piece.
Where the finished piece belongs
Not on a page called testimonials, which nobody visits and which signals that the content is promotional before a word is read.
Put it on the page it is evidence for. A case study about a first-timer belongs on the page about beginner trips; one about a difficult June belongs on the page about June. The reader encountering it is already asking the question the piece answers, and that is worth more than any amount of prominence.
Link to it from the enquiry reply when somebody asks the same question the client had. That is the highest-converting use it will ever get, and it costs one sentence.
And keep the set small and current. Two pieces a year, published where they belong and dated, produces a body of evidence in three seasons that no competitor can assemble quickly, because it can only be built by having had those days and asked at the time.
Common mistakes
Recording without saying so, which is unnecessary risk for no benefit given how simple the alternative is.
Treating consent to be interviewed as consent to advertise. They are different permissions and the second is the one that matters.
Publishing a claim you could not evidence a year later, when the request window runs a year from the last day the claim was made.
Writing the client's words for them, and choosing the most flattering quotation rather than the most specific one. Flattery is discounted automatically; specificity is not.
What surprises people
That federal law permits recording a conversation you are part of, and that this does not settle the question, because state rules differ and several require everybody to agree.
That a business can be required, on written request from a named set of officials, to produce the evidence behind an advertising claim.
That the request may arrive up to a year after the last day the claim was shown, which means the folder has to outlive the campaign.
And that a claim purporting to be based on any fact is enough to bring a page inside that provision, which describes almost every case study ever written.
When not to publish one
When the client is hesitant. A reluctant yes produces a piece you will feel uneasy about and a client who tells somebody they were pressured.
When the day was exceptional and cannot honestly be described as anything else. Publishing it with a caveat is fine; publishing it without one sets an expectation you will spend a season failing.
When the interesting part cannot be told without naming water you protect, which happens more often than guides expect.
And when there is nothing specific in it. A case study whose content is that somebody had a nice time is a testimonial, and testimonials belong in the reviews strategy rather than on a page of their own, as set out in the reviews piece.
The folder, which is the whole system
One folder per published piece, containing the recorded consent, the written publishing permission, the trip date, the interview date, the raw audio, the transcript and a note of where any number came from.
That takes five minutes at the time and is unreconstructable afterwards. It is also the only part of this subject that has consequences, since everything else is craft and this is evidence.
Keep it for as long as the piece is published and for a year after you take it down, which is the window the substantiation provision uses. Then treat the whole set as an asset rather than a chore: three well-evidenced case studies are the most persuasive thing on most guiding sites, and the images that accompany them do half the work, as argued in the trip photos piece.
Recording law differs by state and the difference matters. The federal provision permits recording a communication you are party to, while several states require all parties to consent, and the substantiation provision quoted is one state's. Confirm the exact current rule where you and your client are before recording anything, and where a case study would state a season, a limit, a fee or a licence requirement, check the current position with the authority that issues it before you publish.
Not a template. There is no fill-in-the-blanks structure here beyond the order the five parts belong in, because a case study made from a template reads like one and readers who fish discount it instantly. This is also not legal advice on a particular recording or claim; what is here is what makes a piece defensible, and the folder that has to exist before anybody asks.

Can I record the interview?
Federally, yes, with a caveat that matters. It is not unlawful for a person not acting under colour of law to intercept a wire, oral or electronic communication where that person is a party to it, or where one of the parties has given prior consent, unless the interception is for the purpose of committing a criminal or tortious act. That permits recording a conversation you are part of, and it does not displace stricter state rules, several of which require every party to agree. The practice that works everywhere is to start recording, say what it is for, and let them answer.
What can I be asked to prove?
The facts behind the claims. California's provision makes it unlawful for a business advertising to consumers there to make any false or misleading advertising claim, including claims purporting to be based on factual or objective evidence, claims comparing effectiveness to other products, and claims purporting to be based on any fact. On written request of the Director of Consumer Affairs, the Attorney General, or a city attorney, county counsel or district attorney, the business must provide evidence of the facts the claims rest on. The request may be made within one year of the last day the claims were made.
What should a case study claim?
What happened, dated, to a named person, in stated conditions. Somebody caught their first permit on a difficult day in June is a fact about a day. Somebody will catch their first permit is a promise, and the promise creates both the obligation and the disappointment. Avoid comparisons with other operations, which the provision names specifically and which start fights you gain nothing from. Avoid aggregates unless you counted, since most clients catch fish is a claim about a population you never measured.
When should I do the interview?
About a week after the trip, by phone, not at the dock. At the dock somebody is tired, wet and being polite. A week later they have told the story twice and know which parts are interesting, which is exactly the material you need. Six questions produce everything usable: what made you decide to book, what were you worried about beforehand, what actually happened, what surprised you, what would you tell somebody considering it, and what would you change. Then stop talking, because the useful sentence arrives after a silence.
Is agreeing to be interviewed enough?
No. Agreeing to be recorded and agreeing to appear in your advertising are separate permissions, and the second has to be asked for in its own words. Ask in writing after the interview, naming what you intend to publish: their name or first name only, the water, the date, quoted sentences, any photograph. Most people take the first-name option and it costs the piece nothing. Send them the finished piece before it goes up; nobody has ever objected to seeing a draft, and the corrections usually improve it.
Do I need a transcript?
If any of it is published as audio or video, yes, for three reasons. Federal accessibility guidance describes captions and transcripts as tools providing access to audio content, with transcripts covering audio-only and video-only material such as podcasts. A transcript is also the only part of an audio file a search engine can read, so a case study existing only as audio is one nobody finds. And it is your record of what was actually said, which is the evidence the substantiation question eventually asks for.
What has to be kept, and for how long?
One folder per published piece: the recorded consent to record, the written publishing permission, the trip date, the interview date, the raw audio, the transcript, and a note of where any number came from. That takes five minutes at the time and is unreconstructable afterwards. Keep it for as long as the piece is published and for a year after you take it down, which matches the window in which a substantiation request may arrive.
