How to Create an Ideal Customer Profile
ideal customer profileAn ideal customer profile (ICP) describes the type of business that gets the most value from what you sell, and gives you the most value back. Get it right and it tells you which leads to chase, which channels to fund and what your website needs to say. Get it wrong and you spend 2027 filling the pipeline with enquiries your sales team can’t close.
This guide shows you how to build an ICP from your own closed-won data rather than guesswork, how to test it against your pipeline, and how to use it to plan content, channels and AI Search for next year. There’s a fill-in template halfway down.
What Is an Ideal Customer Profile?
An ideal customer profile is a short description of the company you most want to win: its sector, size, budget, location, the problems it has and the events that push it to buy. In B2B, it describes an organisation rather than a person.
It’s built from evidence. The best ICPs come from looking hard at the customers you already have, especially the ones who stayed longest, spent most and were easiest to work with, and asking what they have in common that your poor-fit customers don’t.
Ideal Customer Profile vs Buyer Persona
The two get mixed up, but they do different jobs. Your ICP tells you which companies to target. Your buyer personas tell you which people inside those companies you need to persuade, and what each of them cares about.
| Describes | A type of company | A person in the buying group |
| Built From | Closed-won and lost deals, CRM data | Interviews, sales calls, surveys |
| Answers | “Should we go after this account?” | “What does this person need to hear?” |
| Used For | Targeting, lead scoring, channel budgets | Messaging, content, sales conversations |
| How Many | Usually one to three | Several per ICP |
Start with the ICP, then build personas for the people in it. We’ve covered the people side on The Digital Marketing Podcast, from designing a buyer persona to marketing to several buyer personas at once and creating your ideal customer avatar.
Why Your ICP Matters More in 2027
Three things have changed how much a vague ICP costs you.
First, buyers shortlist before they speak to you. Pew Research Center found that about half of US adults now use AI chatbots, and more buyers ask ChatGPT, Gemini or Google’s AI Mode who they should hire, getting three or four names back. If you don’t know exactly who your ideal customer is, you can’t know which questions they’re asking, and you can’t check whether your business appears in the answers. Our research into the AI Search buyer journey shows how much of that research now happens before a buyer fills in a form.
Second, the old funnel leaks. A buyer might watch your videos for a year, read a comparison article and ask an AI tool for a shortlist, then book a call the same day. We’ve written about why traditional marketing funnels no longer work; a sharp ICP is how you decide what to say at each of those touchpoints when you can’t see most of them.
Third, lead volume is the wrong target. If marketing is measured on form fills, it will find more form fills. If it’s measured on qualified leads from businesses that match the ICP, it finds better ones. You can’t set that target without writing the ICP down first.
How to Create an Ideal Customer Profile in 7 Steps
Step 1: Start With Your Best Customers, Not Your Wish List
Export every deal you’ve won in the last 12 to 24 months from your CRM. If you use HubSpot, that’s a filtered list of closed-won deals with their associated companies and contacts; our HubSpot agency team sets this up for clients whose CRM data isn’t clean enough to use.
Then pick out your best customers, not just your biggest. Look at:
- Revenue and Margin: Which accounts make you money once the work is done?
- Retention: Who stayed, renewed or bought more?
- Results: Whose problem did you solve well enough that they’d be a case study?
- Fit: Who was easy to work with, made decisions quickly and paid on time?
You’re aiming for a group of 10 to 20 accounts you’d happily clone. If you have fewer, use what you have and treat the ICP as a first version.
Step 2: Compare Them With the Ones That Didn’t Fit
This step is easy to skip, but it’s where the useful insight comes from. Pull a second list: enquiries that went nowhere, deals you lost, and clients who left early. Your ICP is whatever separates the first list from the second.
When we rebuilt our own ICP from a year of closed-won deals, the answer surprised us. The things we’d assumed mattered most, such as company size and how urgently someone wanted to start, barely separated our best clients from poor-fit enquiries. Budget did, along with who the main contact was. We also found that a big budget figure on an enquiry form isn’t proof on its own, so we now check it on the first call.
Write down your own disqualifiers at this stage too: the signs that a lead won’t work out, however keen they sound.
Step 3: Choose the Firmographics That Actually Separate Them
Firmographics are the company-level facts you can usually find before you speak to someone. Common ones include:
- Sector: Which industries appear again and again in your best accounts?
- Size: Revenue or headcount bands.
- Budget: What they spend on your category each month or year.
- Location: Countries or regions you serve well.
- Business Model: B2B or B2C, sales-led or self-serve, recurring or one-off.
- Technology: The platforms they use, if that affects your fit (a CRM, a website platform, an ecommerce system).
Only keep the ones that differ between your best customers and your poor fits. If half your best clients and half your worst are in the same sector, sector isn’t part of your ICP, however much you’d like it to be.
Step 4: Map the Buying Group
Most B2B purchases involve several people. Note who usually finds you, who champions you internally and who signs. In many businesses, the person who first gets in touch is a marketing manager doing the research, and the person who approves the spend is the managing director, finance director or board. That’s the pattern we see in our own deals.
This matters because the champion needs different things from the signer. The marketing manager wants proof you understand the problem and will make them look good. The MD wants to know what it costs, what it returns and what happens if it doesn’t work. Your content and your sales process need to serve both.
Step 5: Find the Trigger Events
Your ideal customer might fit every box and still not buy this year. Trigger events are what turn a good fit into a live opportunity. Look back through your won deals and sales call notes for what was happening when they got in touch. Typical triggers include:
- A Drop in Results: Falling organic traffic, lost rankings or disappearing from AI answers. For us, a loss of visibility in Google or AI Search is one of the most common reasons people book a call.
- A Growth Target: A new market, product or revenue goal for next year.
- A Change of Partner: Frustration with an incumbent agency or supplier.
- A Change of Platform: A rebrand, new website or CRM migration.
- A New Leader: A new marketing director or CEO reviewing what’s in place.
Triggers tell you when to show up and what to say when you do.
Step 6: Write Down What They Search For and Ask AI
Next, list the questions your ideal customer asks before they buy, in their own words. The best sources are your sales calls, the questions in enquiry forms, what people ask at your webinars and what your account managers hear every week.
Turn those questions into two lists:
- Search Terms: The phrases they type into Google. Our guide to keyword research shows how to find and size them.
- AI Prompts: The longer, conversational questions they ask ChatGPT, Gemini or Google’s AI Mode, such as “Which agencies help B2B energy consultancies get more leads?” or “What should I look for in a HubSpot partner?”
The prompt list becomes the set of questions you track. Check which businesses AI tools name for each one, and which websites they cite. Our guide on how to track your brand’s visibility in AI Search explains the tools and the method. If your competitors appear and you don’t, you’ve found your content plan.
Step 7: Test It Against Your Pipeline and Review It Every Quarter
Score your last few months of enquiries against the new ICP. Do the leads that match it convert to sales at a higher rate than the ones that don’t? If they don’t, something in the profile is wrong.
Once it holds up, build it into your lead qualification. Agree with sales which ICP criteria make a lead marketing-qualified, put the key ones on your forms (budget and timing are the usual two) and review the profile every quarter, or whenever you launch a new service or enter a new market.
Ideal Customer Profile Template
Copy this table into a doc or spreadsheet and fill in one column per ICP. Keep each answer short: if a box needs a paragraph, you probably haven’t decided yet.
| Field | What to Write | Your ICP |
| Sector | The industries your best accounts share | |
| Company Size | Revenue or headcount range | |
| Budget | Typical spend on your category | |
| Location | Countries or regions | |
| Business Model | B2B or B2C, sales-led or self-serve | |
| Who Finds You | Usual job title of the first contact | |
| Who Signs | Job title of the decision-maker | |
| Main Problems | The two or three problems you solve for them | |
| Trigger Events | What happens just before they buy | |
| Questions They Ask | In their words: search terms and AI prompts | |
| Where They Research | Google, AI tools, YouTube, podcasts, events, peers | |
| Disqualifiers | Signs a lead won’t work out | |
| Proof They Need | Case studies, sectors, results that reassure them |
Example: An ICP for a B2B Consultancy
Here’s how the template might look for an illustrative UK consultancy selling compliance services to manufacturers. The business is made up; the thinking is what matters.
| Field | Example |
| Sector | UK manufacturers in regulated sectors (food, chemicals, medical devices) |
| Company Size | £10m to £100m revenue |
| Budget | £3,000+ a month on outside compliance support |
| Who Finds You | Quality or operations manager |
| Who Signs | Managing director or finance director |
| Main Problems | Audit failures, slow certification, in-house team stretched |
| Trigger Events | A failed audit, a new export market, a key person leaving |
| Questions They Ask | “How long does ISO 13485 certification take?”; “Which consultancies help food manufacturers pass BRC audits?” |
| Where They Research | Google, ChatGPT, trade associations, LinkedIn, peers |
| Disqualifiers | Under £5m revenue; wants a one-off template, not support |
| Proof They Need | Named manufacturing clients, audit pass rates, sector-specific case studies |
Notice how specific the questions are. Each one is a page this consultancy could write and a prompt it could track.
How to Use Your ICP in Your 2027 Marketing Plan
An ICP that sits in a slide deck changes nothing. Here’s where to put it to work.
Fund the Channels That Reach Your ICP
Look at where your best customers first heard of you, and judge each channel over a long enough window. Many of our own best clients had known us for a year or more before they got in touch, often through our videos, podcasts or webinars, so a channel that looks quiet in a monthly report can still be doing the early work.
Build Content Around Their Questions
Use the question list from Step 6 to plan pages, blogs and videos. Our SEO services start from exactly this kind of research, so the pages you build are designed to rank for the terms your ideal customer searches and to answer the questions they ask AI. A GEO strategy then helps those pages get cited in AI answers.
Check How AI Describes You to Them
Run your ICP’s prompts through ChatGPT, Gemini and Google’s AI Overviews and AI Mode, and see whether you’re named, which competitors are, and which sites are cited. That’s the core of AI Search Optimisation: giving you the best chance of being part of the answer when your ideal customer asks.
Make Your Website Speak to Them
Your ideal customer should land on your site and recognise themselves straight away: their sector, their size, their problems, and case studies from businesses like theirs. Our B2B digital marketing work shows what that looks like in practice.
Make the Case for Budget
If your ICP shows that buyers are researching suppliers in AI tools, use it to argue for the budget to reach them. Our guide to making the business case for AI Search in 2027 walks you through it, from the evidence to the board paper.
Common ICP Mistakes to Avoid
- Making It Too Broad: “UK businesses with a website” describes everyone and helps no one.
- Building It From Your Wish List: Aim for the customers you win and keep, then stretch from there.
- Ignoring the Poor Fits: Without the comparison in Step 2, you can’t tell which traits matter.
- Confusing It With a Persona: Your ICP is a company. Personas are the people in it.
- Leaving Out the Questions: Without the questions your buyers ask, the ICP can’t guide your content or your AI Search work.
- Never Updating It: Markets and services change. Review it every quarter.
Ideal Customer Profile FAQs
What’s the Difference Between an ICP and a Buyer Persona?
An ICP describes the type of company you want to win. A buyer persona describes a person within that company, such as the marketing manager or finance director, and what they need from you. Build the ICP first, then the personas.
How Many Ideal Customer Profiles Should a Business Have?
Most businesses need one to three. If you serve very different markets (say, manufacturers and law firms), each may need its own ICP. More than three usually means the profile isn’t focused enough.
What Data Do I Need to Build an ICP?
At minimum, a list of won and lost deals with company sector, size, location and deal value, plus notes from sales calls. Budget, the job title of the main contact and how they found you make it much stronger.
How Often Should I Update My ICP?
Review it every quarter, and rebuild it when you launch a new service, enter a new market or see a change in who’s converting.
