Five service categories, five different constraints

The same seven layers. Very different failure points.

Every service business moves a stranger through the same path, but where that path breaks is specific to the category. A contractor loses jobs to response time. A consultancy loses them in a silent procurement stage. A clinic loses them to a booking form that only works during business hours.

These pages describe what a growth system looks like in each category and what building one involves. None of them claims a client history Ariadne does not yet have.

Industry · Legal services

Law firms

From a practice-area search to a conflict-cleared, scheduled consultation, with the intake, follow-up, and reporting that keeps a matter from being lost between the enquiry and the retainer.

Usual constraint: The site is organised by practice group rather than by the problem the visitor searched.

Industry · Accounting and bookkeeping

Accounting firms

Built around two recurring operating questions: how enquiry handling performs during a compressed season, and whether the first engagement reflects a client’s longer-term value.

Usual constraint: The site lists services without indicating who they are for, what they cost, or what complexity is in scope.

Industry · Consulting and professional services

Consulting firms

For firms where the sale is long, the buyer is a committee, and the founder is still the only person who can close. The system has to carry credibility, not just capture enquiries.

Usual constraint: The site describes the methodology rather than the problem the buyer has.

Industry · Health and wellness practices

Clinics & practices

Built around booking, capacity, and retention rather than lead volume, with a deliberate boundary between marketing systems and software approved to hold health information.

Usual constraint: Booking is limited to phone calls during business hours, which can create friction for people researching at other times.

Industry · Trades and home services

Contractors & home services

Built around two operating questions worth testing: how fast the business responds, and whether enough information arrives to avoid an unnecessary site visit.

Usual constraint: Median time to first response is not measured, so the team relies on an estimate.

Not on this list?

The seven-layer model applies to any business where a stranger becomes a customer through a considered decision rather than an impulse purchase. Trades, professional services, agencies, B2B specialists, and non-regulated advisory work all share the same shape.

What changes between categories is which checkpoint fails first, how the buyer researches, what qualification actually needs to capture, and which constraints are regulatory rather than practical. The audit works those out for your business specifically, whether or not there is a page here for it.

The categories deliberately excluded are ecommerce and DTC — different mechanics, different stack, and a specialist would do better work than I would.
