Why Most Businesses Get Their Ideal Customer Wrong — And How Better Customer Profiling Increases Sales
Most businesses think they know who their ideal customer is. In reality, they are guessing. They assume their best clients sit in a particular industry, a certain postcode, or a specific company size — usually based on one or two memorable wins, a gut feeling, or what simply “feels” right. That assumption is where the money starts leaking out. Customer profiling done properly is not just a nice-to-have. It is the difference between a marketing campaign that pays for itself and one that quietly drains your budget.
The Problem With “Probably” and “Tends To”
Listen to how businesses talk about their own customers and you will hear the same vague language over and over:
- “Schools are probably our best market.”
- “We tend to do well with manufacturers.”
- “Most of our customers are probably SMEs.”
- “We should target everyone within a 20-mile radius.”
Probably. Tends to. Most likely. These are dangerous words in sales and marketing. If you do not know exactly who buys from you most often, who spends the most, who stays the longest, who converts the fastest, and which sectors genuinely respond best — your marketing is guesswork. And guesswork is expensive.
Most businesses do not have a lead problem. They have a targeting problem.
What Proper Customer Profiling Actually Looks Like
The smarter approach is to profile your existing customer base properly before you spend another penny on outreach. That means looking at the data you already have and asking the right questions:
- Which industry sectors make up your best customers?
- What size companies — by employee count or turnover — convert and retain best?
- Which postcode areas have your strongest presence?
- Which job titles are actually making the buying decisions?
- How much of the wider market are you not yet reaching?
Once you can see that clearly, you stop targeting “everyone” and start targeting the people most likely to buy. That shift alone can transform what you get back from every outbound campaign.
At Data Bubble, this is exactly what we do through our profiling reports. We analyse a client’s existing customer base and identify the patterns hidden inside it — the industries they already perform best in, the decision-makers most likely to respond, and the scale of the untapped market that matches that profile. The result is not just a better list. It is confidence. Confidence that your money is going in the right direction. If you are running B2B data campaigns, knowing your true ideal customer profile before you buy a single record makes every pound work harder.
Real-World Example: When the Data Proves You Wrong
We recently worked with a client who was convinced their strongest market was educational institutions. That was the assumption — and it felt reasonable based on a handful of clients they could name off the top of their heads.
When we profiled their customer base properly, the data told a completely different story. Their real ideal customer was solicitors. Legal firms made up a stronger proportion of their existing base, showed better repeat purchase behaviour, stronger conversion rates and more buying potential overall.
Using that insight, we built a targeted prospect list focused on legal firms, matched to the right company sizes and decision-maker job titles. Their telemarketing conversion rate went from 3% to 5%.
That might not sound like much on paper. But in outbound marketing, that gap is the difference between a campaign that barely covers its costs and one that is genuinely profitable. Better targeting does not just lift response rates — it improves the quality of every conversation, every appointment, and every sale that follows.
It is worth noting that all customer profiling and data activity we carry out is fully compliant with UK GDPR. The Information Commissioner’s Office (ICO) sets out clear guidelines on the lawful use of personal and business data, and responsible profiling sits well within those boundaries when handled correctly.
How to Start Targeting the Right People
Before you increase your advertising spend, launch another email campaign, or book more telemarketing hours, ask yourself one honest question: do you actually know who your best customers are?
If the answer is “I think so” rather than “I know so”, there is a real opportunity sitting right in front of you. Whether you are working with B2C data or targeting businesses, the principle is the same — evidence-based targeting outperforms assumption every single time. The Data & Marketing Association (DMA) consistently highlights that relevance and targeting accuracy are among the top drivers of campaign performance in direct marketing.

Frequently Asked Questions
What is customer profiling and why does it matter for B2B marketing?
Customer profiling is the process of analysing your existing customer base to identify the common characteristics — such as industry, company size, location and job title — that your best customers share. In B2B marketing, it matters because it replaces guesswork with evidence. Instead of targeting a broad audience and hoping for the best, you focus your budget and effort on the businesses most likely to buy, which improves conversion rates and reduces wasted spend.
How can profiling my existing customers help me find new ones?
Once you understand the profile of your best existing customers, you can use that data to build a prospect list of similar businesses you have not yet reached. This is sometimes called a “lookalike” approach. A data broker like Data Bubble can take your customer profile and identify how many matching businesses exist in the wider UK market, giving you a clear picture of your total addressable audience.
How do I know if my current targeting is wrong?
A good indicator is inconsistent campaign results, low conversion rates, or a sense that your messaging is not landing with the right people. If you are describing your ideal customer in vague terms — “probably SMEs” or “tends to be in manufacturing” — that is a sign your targeting is based on assumption rather than data. A proper customer profiling exercise will quickly show whether your gut instinct matches the reality of who is actually buying from you.
