What this lesson covers
Which segment should I choose first, and how do I describe one real person in it?
- Evaluating segment attractiveness
- Concentrated, differentiated and micro targeting
- Building evidence-based personas
- Ideal customer profiles (ICPs)
- Avoiding stereotypes and invented customers
- B2C (business-to-consumer) vs. B2B (business-to-business) callout: the company-level ICP, the buying committee and account-based marketing

Meet Dana at 2 a.m.
Carmen's first persona draft said “retirees who panic.” She deleted it. The job records didn't support it: age didn't predict who called in an emergency. The house did, and the hour did.
So she rebuilt it from evidence: dispatch notes, call times, job addresses and what customers said on the phone.
Dana is the emergency homeowner. She lives in one of the six core zip codes, in a house built in the late '90s with its original water heater. When she calls, it's often after dark, with a towel in one hand and her phone in the other. She'll decide in under two minutes, and she judges on four things: someone answers, the business is close, the stars are good, and nobody surprises her with the price. She has never thought about plumbers before tonight, and she hopes never to again.
Frank manages 40 rental homes for owners who live out of state. He doesn't panic; he needs one number that always answers, photos of the problem, and an invoice the same day. Frank is worth about $40,000 a year in jobs.
Ray wants to chase both. Carmen makes the case for concentrated targeting: win Dana first, in six zip codes, because emergencies are 60% of the business and the whole campaign is built around her moment. Frank gets a micro-targeted plan of his own: a one-page offer and a phone call.

Walking away from 38%
Lena's persona isn't invented. She's assembled from the orders and reviews of about 1,300 heat-dressers.
Andrea is 36 and manages a pharmacy in a hot metro. She crosses a 108-degree parking lot four times a day and still has to look like she's in charge at 4 p.m. She's tried linen from national brands and found it cut for a breezy coast, not a car with a black steering wheel. She pays full price for things that work, buys the same pant in a second color, and tells coworkers where she got it.
Choosing Andrea means choosing not to chase the sale-only buyers, and that's 38% of Lena's customers. It feels like shrinking.
Sam puts it in numbers. Andrea's group returns half as much and comes back four times as often. Concentrated targeting doesn't mean fewer customers forever. It means spending every ad dollar on the customer who's worth keeping.

B2C vs. B2B
Placeholder for the B2C vs. B2B callout: in B2B the ideal customer profile describes a company and the personas describe the roles in its buying committee (the user, the buyer, the approver); introduces account-based marketing.

Key terms
- Account-based marketing (ABM): A B2B approach that treats a short list of specific target companies (accounts) as markets of one, with personalized messages for the people on each buying committee.
- B2B (business-to-business): Marketing and selling to companies and organizations that buy for business use.
- B2C (business-to-consumer): Marketing and selling to individual people who buy for themselves or their households.
- Buying committee: In B2B, the group of people who share a purchase decision, such as the user, the budget holder, a technical reviewer and the final approver.
- Concentrated targeting: Focusing on one segment, or niche, and serving it very well. Also called niche marketing.
- Differentiated targeting: Choosing two or more segments and creating a different offer or message for each one.
- Evidence-based persona: A persona whose details come from real interviews, reviews, sales data and analytics, not from guesses.
- Ideal customer profile (ICP): A description of the customer who gets the most value from a business and is most valuable to it. In B2B, the ICP usually describes a type of company rather than a person.
- Invented customer: A persona detail made up to fill a gap instead of learned from evidence. It feels useful but leads decisions in the wrong direction.
- Micro targeting: Tailoring marketing to very small groups, or even individuals, often using data and ad-platform tools. Also called micromarketing.
- Persona: A short profile of one realistic customer in a target segment, with their goals, problems, habits and words, built from research rather than imagination.
- Segment attractiveness: How worthwhile a segment is, judged by its size, growth, profitability, competition and fit with what the business does well.
- Stereotype: An oversimplified, often unfair belief about a group of people. Personas built on stereotypes lead to bad targeting and offensive marketing.
- Targeting: Choosing which segment or segments to focus marketing effort and budget on.
