This diagnostic begins by acknowledging that existing behavior is not producing the required outcome. The owner identifies three plausible changes but tests them sequentially—ideally one per month—so the effect of each mechanism can be interpreted. The subject matter should remain anchored to an established customer desire, while the delivery mechanism changes through formats such as video, live teaching, workouts, webinars, or podcast appearances. If the business is already active across those mechanisms, the diagnosis moves below social media. Five to eight relevant people are asked candidly why they have not purchased, what is failing to resonate, and what would need to change. The owner then groups recurring answers, selects a workable theme, and applies the learning through the offer and future content.
Origin
Extracted from The Jasmine Star Show during fitness coach Heike Yates's question about standing out in a saturated market despite extensive experience and content activity.
Core principles
- 01What produced the current result may not produce the desired result
- 02Change one major variable at a time so results remain interpretable
- 03Use customer demand to select the topic and experiments to select the mechanism
- 04When content activity is broad but sales remain weak, investigate the business offer
- 05Vulnerability produces more useful feedback than a casual request for advice
- 06Repeated feedback patterns matter more than isolated opinions
How to run it
- 1
Define the stalled result
State precisely what is not happening, such as purchases, inquiries, or audience action, and acknowledge that current behavior is not producing it.
Pro tip Separate visibility metrics from the commercial result you actually need.
Watch out Do not diagnose the problem as “the algorithm” without evidence.
- 2
Choose three candidate changes
Identify three mechanisms likely to move the result, informed by what resonates with the target demographic.
Pro tip Keep the audience need constant while changing how it is delivered.
Watch out Do not imitate creators serving a materially different demographic.
- 3
Test sequentially
Commit to one mechanism for a defined period, such as one month, before moving to the next.
Pro tip Choose a cadence you can execute come hell or high water.
Watch out Testing all changes simultaneously prevents attribution.
- 4
Escalate beyond social media
If you already use the major content formats consistently, investigate the service, package, personality fit, and pricing rather than adding another channel.
Pro tip Treat extensive activity with weak conversion as a business-model signal.
Watch out Do not use aesthetic critique as a substitute for diagnosing the real issue.
- 5
Interview non-buyers vulnerably
Ask five to eight close, relevant people for candid feedback and explain that the business genuinely needs their help.
Pro tip Set a specific date by which you need their response.
Watch out A casual request will often produce polite reassurance instead of useful truth.
- 6
Ask three diagnostic questions
Ask what you could do better, what does not resonate online, and what it would take for that person to become a customer.
Pro tip Record the answers in the respondents' original language.
Watch out Do not debate or defend yourself during the interview.
- 7
Connect the patterns
Circle repeated themes, decide which can be addressed, and translate them into an offer or communication change.
Pro tip Share a relevant lesson publicly to test whether the broader audience recognizes it.
Watch out Do not rebuild the business around one isolated comment.
In the wild
A coach for women over 50 knows mindset resonates but her direct posts are not converting. She tests one new mechanism each month: first live mindset coaching, then workouts designed for women over 50, then guest appearances on aligned podcasts, tracking inquiries and purchases separately.
→ She can identify which delivery mechanism changes commercial response without abandoning her direct personality.
After confirming she already publishes posts, videos, Lives, a podcast, and YouTube content, the coach asks five relevant people why they have not invested. She gives them a deadline, groups recurring comments about the package and messaging, and addresses the strongest pattern in a candid Instagram Live.
→ The diagnosis moves from speculative social-media tactics to evidence about the actual buying barrier.
Common mistakes
Changing everything together
Simultaneous experiments make it impossible to determine which change caused the result.
Seeking reassurance instead of truth
People often say the business is doing great unless the owner explicitly signals vulnerability and asks for candid help.
Treating every stall as a content problem
When broad content execution already exists, the blocker may be the offer, package, pricing, positioning, or trust.
Is it for you?
Best for
Experienced service providers who publish consistently but cannot identify why attention is not converting into purchases.
Not ideal for
Businesses without enough baseline activity, audience contact, or time to run controlled experiments.
From the transcript
“I want to test three different approaches, but you will not test all three different approaches at the same time”
“I believe that the hard work of growing a business when the business isn't growing is asking five to eight people who are closest to…”
“And then once you distill it and once you sit with it, start circling or connecting the dots between similar things that people are saying.”
