Meet Sarah.
She's 42, lives in Surrey, drives a Range Rover Evoque, shops at Waitrose, worries about her children's future, reads the Guardian on weekends but votes Conservative. She enjoys Pilates on Tuesday mornings, has a Pinterest board called "Garden Ideas" and listens to a carefully curated Spotify playlist of acoustic covers while batch-cooking on Sundays.
She values authenticity. She cares about sustainability, but not enough to give up her Nespresso machine. She's time-poor but money-comfortable. She makes purchasing decisions based on trust and recommendation, often consulting her book club friends before committing to anything significant.
Congratulations. You've just written a make believe contestant bio for a dating show nobody asked to be on.
You've seen this sort of exercise before. Maybe you've done it.
Spent hours in a workshop, giving your fictional customer a name, a stock photo face, a backstory. You discussed her hopes, her fears, her relationship with her mother. You debated whether she'd prefer John Lewis or Marks & Spencer. Someone suggested she has a cockapoo called Archie.
By the end, you had a beautiful slide deck. A "customer avatar" that felt real. A persona you could "speak to" in your marketing.
And then you tried to write an ad.
And none of it helped.
Because Sarah doesn't exist. And even if she did, knowing her dog's name doesn't tell you a single thing about why she'd click on your ad instead of scrolling past.
Here's what twenty years of lead generation has taught me: customer avatars are bollocks.
Personas are theatre. And the entire industry built around "dream customer workshops" exists to sell consultancy hours, not to help you generate leads.
Let me show you what actually works.
I need to be direct about this, because you've probably been told the opposite by every marketing course, agency, and guru you've encountered.
The customer avatar exercise, where you create a detailed fictional person with demographics, psychographics, hobbies, fears, and a name, is not just unhelpful. It's actively harmful. It wastes time you could spend on things that matter, and it gives you false confidence that you understand your customer when you don't.
Here's why.
Demographics don't click ads.
