Why Most 'Ideal Client Avatar' Exercises Produce a Persona Nobody Ever Uses Again
Almost every marketing course includes a "build your ideal client avatar" exercise, usually done once in a workshop, usually naming a persona like "Sarah, 35, busy professional" who then never gets mentioned again. We love a good workshop as much as anyone — what we don't love is watching a business spend half a day building a persona that's lived in a Google Doc, unopened, ever since. 💖 The exercise itself isn't the problem. What goes into it, and what happens after, is.
What most ideal client avatar exercises get wrong
Personas usually get invented from assumption rather than built from observed behaviour — demographic guesses that don't actually predict who buys. They're often too broad to be useful ("busy professionals who value quality" describes almost everyone). They get built once and never revisited. And critically, they're rarely tied to a specific decision they're meant to inform, which is exactly why they end up forgotten.
- Pull your last 10-20 actual enquiries or closed-won clients — not imagined ones.
- For each, note: the specific trigger that made them reach out NOW (not a generic pain point — the actual triggering event), where they found you, the objection that almost stopped them enquiring, and what they asked in the first conversation.
- Look for the two or three patterns that repeat across most of them — that's your real signal, not demographics.
- Write the persona as a decision tool: "When writing this headline/ad/email, does it speak to [trigger] and pre-answer [objection]?" — not a biography.
- Revisit it every time you review ad performance or lose a sale you expected to win. Update it; don't rebuild from scratch each time.
How to put this into practice
- Gather actual data before touching a persona template — CRM notes, enquiry form answers, sales call notes.
- Look for patterns in triggers and objections, not demographics.
- Write the persona as a short checklist, not a biography with a stock photo attached.
- Attach it to a specific decision — ad copy, a landing page headline, email subject lines — rather than leaving it as a standalone reference document.
- Set a recurring review, quarterly or after any batch of lost deals, instead of treating it as a one-off deliverable.
Mistakes to avoid
- Inventing demographic details (age, income, hobbies) that don't actually predict who buys.
- Building it once in a workshop and never updating it.
- Not tying the persona to a specific marketing decision it's meant to inform.
- Making it too broad to be useful — if it describes almost everyone, it won't sharpen anything.
- Skipping the objection and trigger data in favour of a biography-style writeup.
Frequently asked questions
Is the ideal client avatar exercise completely useless, then?
No — the exercise itself is fine. The problem is usually the inputs (invented rather than observed) and the lack of ongoing use, not the underlying concept.
How many real clients or enquiries do we need before building one?
Ten to twenty is a reasonable starting sample for a small business, though it depends on how varied your client base already is — a more varied base may need a larger sample before patterns emerge clearly.
Should we have multiple personas if we serve different types of clients?
Often yes, but keep it to two or three maximum — beyond that, the document tends to stop being usable for actual decisions.
How do we know if our persona is actually working?
There's no single metric for this. The real test is whether it's changing what you write or where you spend, not whether it simply "feels right" when you read it back.
