One of the most common B2B marketing mistakes sounds completely reasonable: “We can work with almost any company.” Maybe you can. But that does not mean you should market to all of them.

When your target market is too broad, your website becomes generic. Your advertising becomes expensive. Your SEO strategy spreads across too many topics. Your sales team spends time on companies that are unlikely to buy, difficult to close or simply not a good fit. And your content starts sounding like everyone else’s.

This is where an Ideal Customer Profile, or ICP, becomes important. An ICP helps answer a deceptively simple question: Which companies should we actually be trying to attract?

The better you can answer that question, the easier it becomes to decide what content to create, which keywords to target, where to advertise and which prospects deserve your sales team’s attention.

What is an Ideal Customer Profile?

An Ideal Customer Profile describes the type of company that is the best fit for what your business sells. Not every company that could purchase from you belongs in your ICP.

Your ideal customers are the organizations where there is a particularly strong match between:

• the problem they have
• the solution you provide
• their ability and willingness to buy
• the value they can receive from your solution
• the value of the relationship to your business

For a B2B software company, this might be a particular type and size of organization with a specific operational problem. For a web development agency, it could be established companies whose websites have become a bottleneck for growth. For a manufacturer, it could be distributors operating in particular markets with certain purchasing volumes.

The purpose isn’t simply to make your potential market smaller. It is to make your marketing more relevant.

ICP is not the same as a target audience

These terms are often used interchangeably, but they answer different questions. A target market can be relatively broad:

European B2B companies.

An ICP goes considerably deeper:

Established European B2B companies with complex products, an existing sales organization and a website that no longer supports their current sales process.

A buyer persona goes in another direction. It describes the people involved in the purchase, such as a Marketing Director, CEO, Head of Sales or Procurement Manager. The ICP identifies which organizations you want to reach.

Buyer personas help you understand the people involved in buying within those organizations. That distinction matters because B2B purchases are rarely made by one individual.

Gartner research published in 2025 found that B2B buying groups can include five to 16 people across as many as four functions. The same research found that buying-group consensus strongly affects the quality of the eventual purchase. Source: Gartner

Your marketing therefore cannot be built around one imaginary decision-maker alone.

“Everyone who could buy from us” is not an ICP

Suppose your company develops B2B online stores. Technically, thousands of businesses could purchase your service. A small wholesaler with five employees could. A manufacturer selling through distributors could. A multinational company replacing an old ordering portal could. They all need “B2B e-commerce”, but these are completely different customers.

They have different:

• budgets
• problems
• buying processes
• technical requirements
• integrations
• decision-makers
• sales cycles
• expectations

Trying to communicate with all of them using the same message usually produces something like:

We provide innovative digital solutions tailored to your business needs.

It applies to almost everyone. And that is precisely the problem.

A weak ICP makes marketing more expensive

When you don’t know exactly who you want to attract, almost every marketing channel becomes harder to use effectively.

SEO becomes unfocused

You start targeting every keyword remotely connected to your services. Instead of building authority around the problems your best customers actually have, you create disconnected content hoping some of it will generate traffic. More traffic is not necessarily the goal.

The right traffic is.

Paid advertising becomes broader

Broad targeting means paying to reach companies that may never become customers. You can improve an advertisement endlessly, but if the wrong companies are seeing it, optimisation has limits.

Outbound becomes generic

Without a clear ICP, sales teams build large prospect lists and send similar messages to everyone. The result is often more outreach but very little relevance.

Your website becomes vague

This may be the biggest problem. When a website tries to speak to everyone, it becomes difficult for the right customer to recognise themselves.

Compare:

We develop high-quality e-commerce solutions for businesses.

with:

We build B2B ordering platforms for manufacturers and wholesalers that need customer-specific pricing, ERP integrations and automated ordering.

The second message deliberately excludes some companies. But to the right company, it is considerably more relevant.

Your ICP matters before buyers contact you

This has become particularly important because much of B2B vendor selection happens before a conversation with sales ever begins.

The 2025 6sense Buyer Experience Report studied nearly 4,000 B2B buyers and found that buyers evaluate an average of 5.1 vendors, with approximately 3.6 vendors already on their shortlist on Day One.

More importantly, the eventual winning vendor was already on that initial shortlist 95% of the time. Source: 6sense Buyer Experience Report

The research also found that 94% of buying groups ranked their shortlist before engaging with sellers.

Think about what this means for B2B marketing.

If your company only becomes convincing once a salesperson gets on a call, you may already be too late.

Your potential customers need to understand:

• who you work with
• what problems you solve
• why your approach is relevant
• what makes you different

before they contact you. And that becomes much easier when you know exactly which customers you want.

ICP and Demand Generation

This connects directly with Demand Generation. In our previous article, we discussed the difference between creating demand and capturing demand that already exists.

Demand Generation aims to build awareness and preference before a potential customer is actively looking for your solution. But there is an obvious question:

Whose demand are you trying to generate?

Without a clear ICP, Demand Generation can easily become content creation for the sake of content creation.

More posts. More videos. More impressions. More website visitors. But from whom?

A strong ICP gives Demand Generation direction.

Instead of trying to become known by everyone in your industry, you can become highly relevant to a specific group of companies that are valuable to your business.

ICP and Demand Capture

The same principle applies when buyers are actively looking for a solution. This is the Demand Capture side of the equation.

Your potential customer might:

• search Google
• ask an AI assistant for recommendations
• visit comparison websites
• read reviews
• ask colleagues
• compare vendors
• visit your website

At this point, relevance becomes critical. If they arrive on your website and immediately see that you understand companies like theirs, the decision to investigate further becomes easier. If they see generic claims that could apply to any business, you give them very little reason to remember you. A good ICP therefore affects both sides:

Demand Generation: become known by the right companies before they need you.

Demand Capture: become the obvious relevant option when they start looking.

Firmographics are useful, but they are not enough

ICP exercises often begin with a spreadsheet:

• Industry: SaaS
• Employees: 50–500
• Location: Europe
• Revenue: €5M–€100M

This information can be useful. But it doesn’t explain why a company would buy. Two businesses with 200 employees in exactly the same industry can have completely different needs. One might have launched a new market. Another might have hired a new sales director. One may have a modern technology stack. Another may be running a ten-year-old system that employees hate using. One might be growing quickly. Another may be cutting costs. Demographics and firmographics describe the organization. Buying context explains why the opportunity exists.

Look for buying triggers

A strong ICP therefore shouldn’t only describe what the company looks like.

It should also consider what is happening inside that company.

Gartner reports that around 99% of B2B purchases are associated with organizational change, such as digital transformation, operational changes or shifts in strategic direction. Source: Gartner

Those changes can create buying triggers.

For example:

• entering a new market
• rapid company growth
• replacing legacy software
• launching e-commerce
• hiring a new leadership team
• changing suppliers
• introducing a new product line
• expanding internationally
• restructuring sales operations
• implementing automation

This is much more useful than simply knowing that the company employs 200 people.

It helps explain why they might need your solution now.

How to identify your Ideal Customer Profile

You don’t have to invent your ICP in a brainstorming meeting.

Start with evidence.

Look at your existing customers.

Ask which customers:

1. receive the most value from what you provide;
2. are profitable for your business;
3. are relatively easy to work with;
4. understand the value of your solution;
5. have problems you are particularly good at solving;
6. stay with you or buy again;
7. you would actively like to find more of.

Then look for patterns.

Industry may be one.

Company size may be another.

But the most useful patterns are often deeper:

• What happened before they contacted you?
• What problem were they trying to solve?
• Why wasn’t their existing solution good enough?
• Why did they decide to act now?
• What alternatives did they consider?
• Who participated in the decision?
• What nearly prevented the purchase?

These questions reveal far more than demographics alone.

Your ICP should influence your website

Once you understand your ideal customer, it should be visible throughout your website.

Not necessarily as a page titled “Our ICP”.

Your positioning should demonstrate it.

Your homepage should communicate problems your ideal customers recognise.

Your service pages should explain solutions in their language.

Your case studies should feature situations similar to theirs.

Your FAQs should answer the questions that appear during their buying process.

Your content should help them understand and solve the problems that eventually lead to your service.

And your calls to action should match how those buyers actually want to engage.

This matters because modern B2B buyers move between multiple digital and human touchpoints rather than following a simple linear funnel. Gartner describes six recurring buying jobs, including problem identification, solution exploration, requirements building, supplier selection, validation and consensus creation. Source: Gartner

Your website should help the right customer through those decisions, not simply push everyone toward “Book a demo”.

Don’t make your ICP too narrow either

There is another extreme. Some companies create an ICP so specific that almost no company qualifies. For example:

SaaS companies with 137–245 employees, €12–18 million revenue, operating in Germany, using HubSpot, hiring at least three salespeople and whose CEO has recently posted about AI.

Precision can look sophisticated without actually being useful. An ICP should help you make better decisions. It should not become an arbitrary checklist. You need enough specificity to understand who deserves your marketing and sales resources, while leaving room for companies that clearly have the problem you solve.

Your ICP can change

An Ideal Customer Profile is not something you create once and keep forever. Your business changes. Your product changes. Markets change. Your best customers today may be different from the customers who helped you start the company. Review your ICP as you collect more information.

Look at:

• which customers close
• which deals are lost
• which customers generate the most value
• which projects are most profitable
• which customers stay
• which companies respond to your marketing
• which problems appear repeatedly

Your ICP should become more accurate as your business learns.

Better B2B marketing starts with choosing who matters

Marketing to fewer companies can feel uncomfortable. Businesses naturally want more opportunities, not fewer. But defining an ICP does not mean refusing everyone outside it.

It means deciding where your limited marketing and sales resources should be concentrated. You can still sell to companies outside your ICP. You simply stop building your entire marketing strategy around them.

Because the goal of B2B marketing isn’t to make every company think:

“They could probably help us.”

It is to make the right companies think:

“They understand exactly what we need.”

And if B2B buyers are already forming and ranking vendor shortlists before speaking with sales, that recognition needs to happen much earlier than the first sales call.

What’s next?

Once you define who your ideal customers are, another question appears: Should every person or company that shows interest become a lead?

Not necessarily. More leads can make a marketing dashboard look impressive without producing more customers or revenue.

In the next article, we’ll look at why more B2B leads don’t necessarily mean more customers, and why lead volume can become a misleading measure of marketing performance.
