TL;DR
Ask a dermatology marketing agency for evidence of the business task it claims to improve. Request accepted page changes, working inquiry routes, service-specific administrative events and a documented attribution method where relevant. Keep treatment outcomes, clinical photographs and medical quality separate from proof of marketing contribution. A clinically impressive example does not establish that an agency generated the inquiry or improved the receiving process.
Translate the sales proposition into a verifiable task
A proposal might combine successful treatment images with a claim that the agency grows a dermatology practice. As a buyer, identify which marketing proposition you are expected to accept. Does the supplier demonstrate accurate service information, functioning access, relevant inquiries, completed consultations or a financial outcome? Each calls for different records.
Do not make the procurement test about whether a particular patient's treatment succeeded. Clinical quality and outcomes need their own appropriate evidence and professional interpretation. A photograph or medical testimonial does not, by itself, identify what the agency changed, where an inquiry came from or what the practice supplied.
For U.S. advertising, the FTC says claims must be truthful, nondeceptive and evidence-based. FTC advertising guidance. This supports asking for substantiation, not concluding that an unnamed supplier broke the law. The actual claim and professional rules need appropriate review for their jurisdiction.
Build a business-evidence request
Use this original buyer's worksheet. Ask for appropriately shareable summaries, public work samples or a synthetic demonstration rather than identifiable clinical material.
| Agency proposition | Business evidence to request | What remains outside that evidence |
|---|---|---|
| We improved medical access information | Approved before-and-after public wording, fact ownership and demonstrated appointment route | Clinical quality, universal coverage or appointment growth |
| We clarified cosmetic consultation demand | Actual invitation, service-intent definitions and supported inquiry categories | Suitability for treatment or a guaranteed purchase |
| We repaired an inquiry handoff | Reproducible defect, implementation record and receiving-team acceptance test | Every real submission or later clinical outcome |
| We improved discovery | Defined observations, dates, question or query scope and underlying source evidence | Guaranteed recommendations or causal patient acquisition |
| We generated relevant appointments | Included service cohort, source method, duplicate rule and verified administrative event | Incremental causation unless the method supports it |
| We produced financial value | Finance-defined event, actual included costs, allocation, cutoff and linkage limitations | Profit or return inferred from gross charges or treatment images |
Record the exact claim ___; evidence received ___; supported conclusion ___; missing inference ___; relevance to proposed scope ___. Keep the supplier's controllable work separate from the practice's scheduling, billing, clinician and procedure resources.
Ask for a mixed-service proof bridge
A dermatology example should preserve what the original invitation promoted and what the later event represents. Medical appointment requests, cosmetic consultations and procedures cannot become a combined success count merely because the practice offers them all.
For a medical-access claim, ask which service and provider route the page described, who approved the access facts and what the tested appointment action did. Do not demand diagnoses or treatment results. For a cosmetic-consultation claim, ask what the consultation offer included and whether the later event was a request, confirmation or attendance. Keep any procedure event separately named.
For a campaign that relied on shared staff or rooms, ask what the practice supplied and whether those resources were available. A work sample may demonstrate useful page design without showing that the same operating conditions exist in your practice. An agency can have made a real contribution while the example remains unsuitable as your forecast.
Use a bridge record: original promoted task ___; supported inquiry category ___; verified later administrative event ___; practice-supplied resource ___; unavailable connection ___. Require the fields relevant to the actual proposition, not a broad export to make the case study appear complete.
Request the least sensitive sufficient demonstration
An approved synthetic test can show a public route and receipt behavior. A redacted deliverable may show the editorial change. A properly reviewed aggregate can describe administrative activity within stated limits. None should be relabeled as a full patient-outcome audit.
Ask the vendor what it can substantiate within legitimate confidentiality boundaries. If the evidence cannot support a performance claim, assess the narrower work sample or reporting demonstration instead. Do not pressure another practice to disclose sensitive records merely to earn your confidence.
The data-request guide helps connect the task to proportionate evidence. The source-check guide tests the exact proposition. This procurement record adds the boundary between evidence of a marketing task and clinical material that does not establish that task.
Compare vendors using the same evidence ladder
Give competing providers the same approved service brief and business question. Ask what they would change, who verifies the facts, what operational responsibility remains with the practice and how acceptance is demonstrated. Do not rank suppliers by the most dramatic treatment imagery or the largest undifferentiated growth headline.
Google's SEO hiring guidance recommends asking about prior work, measurement, relevant experience and communication about proposed changes. Google's hiring guidance. Use those questions alongside the dermatology proof bridge; the guidance does not certify a provider or predict results.
GetPatients has a commercial interest in healthcare visibility services. Apply this framework to its proposals as well. No agency ranking, patient outcome, acquisition benchmark or financial return is supplied here.
End with a bounded purchasing conclusion
Classify the response as supported for the named business task, useful only as a limited work sample, or insufficient for the proposition. Record which inference changes the buying decision. Ask for a precise missing record when it can be provided appropriately.
You may choose a diagnostic project, a clearly scoped implementation or another supplier. What matters is that the purchase does not depend on turning medical treatment evidence into unsupported marketing credit. Preserve uncertainty while accepting work the evidence actually demonstrates.
Frequently asked questions
Are clinical photographs irrelevant to every marketing review?
They may be part of actual creative that needs its own permissions, factual review and context assessment. They do not alone prove inquiry generation, handoff repair or agency-attributable financial value.
Must a vendor share another practice's financial records?
No. Respect legitimate limits and request a suitably limited explanation or demonstration. Keep an unverifiable financial claim outside your forecast.
Can a strong work sample justify a small project?
It can inform that decision when the proposed scope and acceptance evidence fit your needs. Do not silently treat demonstrated craft as proof of a guaranteed acquisition outcome.
