Who Are Your Target Customers? A Step-by-Step Method

Your target customers are the groups you deliberately focus on serving. A useful definition explains their needs, buying circumstances and suitability for your offer, rather than simply naming everyone who could conceivably use it.

You can draft that definition using your customer records, a simple scoring exercise and a short profile. This guide provides a copyable template, a worked example and a practical way to test your assumptions before increasing marketing spending.

Who are your target customers? A working definition

A target customer is a person or organisation you choose to pursue because there is a plausible fit between its needs and your offer. That fit includes the value you can deliver, the buying process, affordability and your ability to serve the customer sustainably.

“Everyone who needs marketing help” provides little direction. “Owners of small UK service businesses who manage marketing themselves and need to choose their next quarter's priorities” gives you a starting point for research, messaging and channel choices.

The second definition is still a hypothesis. You need evidence that these people recognise the problem, can be reached and will take a useful next step.

Why a clear definition helps a small team

A priority audience helps you decide what to explain on your website, which opportunities deserve attention and where to spend limited time. It also gives you a reference point for reviewing enquiries: are you attracting the people your offer is designed to help?

You do not have to reject every customer outside the profile. Treat the profile as a guide to proactive marketing and service fit, while examining unexpected opportunities on their merits.

How do you define an ideal customer profile?

An ideal customer profile, or ICP, describes the characteristics of a customer likely to receive substantial value from your offer and be a sustainable fit for your business.

In B2B marketing, it usually describes the organisation or account. The people who use, influence and approve the purchase can be recorded separately. Consumer businesses can adapt the method around needs, situations and buying behaviour instead of company characteristics.

Build the profile in three passes:

1. Choose fit criteria relevant to the offer and your capacity.
2. Examine actual customers, lost opportunities and available evidence.
3. Write a concise profile and identify the assumptions that need testing.

A guided process such as Vyzion's Diagnose, Design and Deploy can help connect that assessment to marketing choices and actions.

What information belongs in an ICP?

Use six fields to keep the profile practical.

Add evidence, dates and unknowns alongside the fields. Do not turn a guessed budget or preferred channel into an established customer characteristic.

Firmographic and behavioural criteria

Firmographics describe organisations: sector, size, location or structure. Behavioural evidence describes actions, such as repeat purchasing, product use, referrals or the steps taken before a sale.

Both can matter. A regulated supplier may need customers with specific operating requirements, while a subscription product may learn much from sustained use and retention. There is no universal rule that behaviour should always outweigh firmographics.

Also distinguish what you know before a sale from what you learn afterwards. Renewal and support workload can help you understand existing customers, but you cannot assume those outcomes for a new prospect based on its sector alone.

Example profile for a service business

This example is hypothetical:

We prioritise owner-managed UK professional-service firms with small teams that need a consistent way to follow up enquiries. The owner currently handles sales alongside delivery and wants fewer enquiries to be forgotten. We provide a straightforward follow-up process and implementation support. We need to verify the buying trigger, affordable scope and role of any existing software before offering a proposal.

The profile should help you ask better questions. It should not claim that every small professional-service firm has the same problem or budget.

Define boundaries without labelling people as time-wasters

Record practical reasons an engagement may not fit: required work outside your expertise, a budget below the cost of delivery, an unavailable deadline or a service requirement you cannot meet.

A price negotiation or a delayed decision does not automatically make someone a poor customer. Investigate whether the issue is fit, an unclear offer, procurement requirements or expectations that need discussing.

What data should you use to identify best-fit customers?

Start with your own records

Review sales, billing, delivery and support information together. Revenue alone does not establish profitability or customer success.

Useful questions include:

• Which customers received the intended result?
• Which orders generated a worthwhile contribution after delivery costs?
• How much support or custom work was required?
• Who returned, renewed or referred another suitable customer?
• Why did other customers leave or decide not to buy?

Where possible, examine a relevant period or cohort rather than simply the last ten customers. A recent batch may reflect one campaign or a seasonal pattern. For a small business, even a few records can help, provided the limits remain visible.

Use public information as supporting context

Companies House provides free public company information, including company type, status, registered office and stated business activity. Filings can add useful context, but they do not tell you who buys your product or establish a prospect's current budget.

Check dates and available detail. Not every filing provides turnover or a complete picture of financial performance, and a registered office need not be the operating location. Corroborate important conclusions rather than treating the register as a definitive assessment of financial health or customer fit.

Public reviews can reveal customer language and concerns, but they are a selective sample. LinkedIn and company websites can suggest roles and activities; verify information that matters to the buying decision.

Worked example: scoring customers against fit criteria

A scoring exercise can make assumptions and trade-offs easier to discuss. It is a decision aid, not a statistical prediction of buying behaviour.

Choose criteria and define the scale

Suppose a service business uses these illustrative criteria:

For each criterion, use 1 for weak fit, 3 for moderate fit and 5 for strong fit, with 2 and 4 for intermediate cases. Define these anchors more precisely for your business. Mark unknowns separately rather than scoring them as poor fit without evidence.

Calculate the weighted totals

Multiply each 1–5 score by its weight, then add the results. The cells below show the raw scores; the headings show the weights.

These customers and figures are fictional. Client A's calculation is (4 × 3) + (5 × 3) + (4 × 2) + 3 + 5 = 43.

Interpret patterns, then check the explanation

Ask what higher-scoring customers have in common and whether those characteristics plausibly explain the result. Perhaps they have a recurring problem that suits a standard service, rather than simply sharing an industry.

Review lower scores too. They might reflect an unsuitable offer, unclear scope or a delivery problem you should fix. Do not assume the customer is at fault or that a low score justifies abandoning a relationship.

Try modest changes to the weights. If the ranking changes dramatically, the result depends heavily on judgement and should be treated accordingly. Essential requirements can also be recorded as separate qualifying conditions rather than averaged into a total.

How do buyer personas differ from an ICP?

For a B2B offer, the ICP describes the organisation you prioritise. A buyer persona describes a relevant person within that organisation: their responsibilities, concerns, information needs and role in the purchase.

One organisation may involve several roles. A school software purchase, for example, could involve a teacher, budget holder, IT lead and data protection staff. Describe roles supported by evidence rather than inventing detailed personal biographies.

You can develop the profile and role understanding together as you learn. There is no requirement to finish one perfectly before investigating the other.

How should charities and school suppliers adapt the method?

Clarify whether you are defining customers for a supplier or audiences for the organisation itself. A charity may need separate descriptions for beneficiaries, donors, commissioners or volunteers because they contribute and receive value differently.

For suppliers, record the user, payer and approval process where these differ. Do not assume every charity purchase has an external funder or that every school uses the same budget timetable.

The Charity Commission register covers England and Wales; Scotland and Northern Ireland have separate regulators, as explained in the government's charity registration guidance. Not every charity appears on that register, so absence alone does not establish that an organisation is not charitable.

For school sales in England, consult the DfE's buying guidance. Confirm the school's or trust's own procurement process, budget approval dates and relevant product requirements. Different school types and purchasing arrangements can have different processes.

How do you test target-customer assumptions?

Use interviews to investigate behaviour

Begin with a manageable number of relevant conversations, perhaps five, then assess what remains uncertain. Ask about a recent problem, current alternatives, spending decisions and barriers to change.

If several people describe a similar problem, you have a reason to investigate further. That is not proof of market size, willingness to pay or repeatable acquisition. Different answers may reflect distinct use cases rather than a failed profile.

Add a behavioural test

Choose a useful next step: requesting a demonstration, trying a product, attending a session or considering a clearly scoped proposal. Match the test to the stage of the business.

Set an affordable cash and time limit, identify what you expect to learn and record how people reached the test. Follow community rules and applicable marketing requirements when inviting participation.

No response may mean weak reach, an unclear message, poor timing or an unsuitable offer. Check those factors before concluding that the customer group is wrong. Likewise, clicks and positive comments are weaker evidence than appropriate use or an actual purchase.

When should you revisit your customer definition?

Review when customers leave unexpectedly, delivery costs rise, prices change, a new use case emerges or market conditions alter. A quarterly check is a useful starting point, but the depth should reflect the amount and importance of new evidence.

Ask:

1. Who bought, used or renewed, and how did that compare with the profile?
2. Who did not progress, and what reasons do we know?
3. Did the work create value for both the customer and the business?
4. Which assumptions should change or be tested next?

Keep dated versions and record why you changed the profile. Frequent updates can reflect learning rather than failure; a stable definition can reflect strong evidence or insufficient research. Judge the evidence, not the number of rewrites.

How do you turn the profile into marketing decisions?

A useful ICP helps you select a problem to lead with, evidence to show, a route to investigate and an appropriate next step. It does not automatically establish that LinkedIn, email or paid social will work best.

For example, a founder might use a recurring problem found in interviews to create a short guide, ask a relevant partner to share it and invite suitable readers to a demonstration. The plan should state who owns the work, its deadline, cash allowance, time estimate and outcome measure.

Separate completed tasks from customer outcomes. Publishing the guide is delivery; relevant enquiries and paid work are different results to review.
