STP analysis: how to stop selling to everyone at once

STP analysis in B2B: where to start when leads don't convert into sales

A familiar situation at a services or manufacturing company: marketing generates 60 inquiries a month, salespeople say 40 of them are a waste of time, and leadership asks why the cost of acquiring a customer keeps rising. At this point most companies reach for a new tool, a new channel, or a new agency. Far more often the problem sits earlier, in the fact that the company never decided who it is really talking to.

STP analysis (segmentation, targeting, positioning) is a sequence of three decisions: which groups we divide the market into, which of them we serve, and how we want to be perceived within them. It sounds like a textbook exercise, but in practice it is the only one that lets you tell a salesperson: don't call this company, it isn't in our segment. Without that sentence, every lead looks equally promising until it turns out it won't buy.

In this article I show how to run an STP analysis at a B2B company, where it most often derails, and how to connect it with the rest of your B2B marketing strategy so it doesn't end up as a document in a drawer.

B2B market segmentation: criteria that make sense in practice

Segmentation is the division of a market into clearly defined subgroups that can be treated as separate target markets and served differently. In marketing literature this is known as segmentation by criteria, meaning the classification of a market according to adopted criteria (Kreutzer, R., Marketing Management, ch. 3.2.3). The key phrase is "clearly defined". A segment that reads "small and medium-sized companies" is not a segment, it is the entire market.

In B2B, three layers of criteria work well when applied together:

• Firmographic: industry, headcount, revenue, ownership structure, location. This is the layer that is easiest to pull from databases and industry registries.
• Situational: what is happening inside the company right now. An ERP replacement, entry into a new export market, a change of owner, the launch of a new production line. These events create real demand, not just potential.
• Behavioral: how the company buys. Tender or direct purchase, a decision cycle measured in weeks or quarters, who signs off, who blocks.

A practical note from projects we have run: at manufacturing companies with 50 to 250 employees, segmentation by industry is almost never enough. Two companies in the same industry with similar revenue can have a completely different purchasing process, because one has a procurement department with procedures and the other buys directly through the owner. The behavioral criterion separates them more effectively than the firmographic one.

Targeting: choosing the segments you can actually serve

Once the market is segmented, the next decision is which segments we serve. Marketing theory frames this as a choice between an undifferentiated strategy (one marketing mix for the entire market) and a differentiated one (separate offers for several segments), see Kreutzer, R., Marketing Management, chapter 3.2.3. In B2B, an undifferentiated strategy almost always ends with an offer so generic that it convinces no one.

When choosing segments, it is worth evaluating them across four dimensions, in this order:

1. Size and growth. Is the segment large enough to sustain a sales team, and is it growing or shrinking.
2. Accessibility. Can you reach these companies in a predictable way: through trade shows, chambers of commerce, LinkedIn, your contact database, referrals.
3. Ability to serve. Do you have the people, competencies, and capacity to serve this segment. A segment you cannot serve is worse than no segment at all, because it generates promises you cannot keep.
4. Profitability. This concerns customer lifetime value and the cost of acquiring that customer, rather than the margin on a single transaction.

The most common targeting mistake is choosing a segment out of ambition rather than capability. At one workshop, a sales director said: "We have 12 salespeople, but we want to move into enterprise". Six months later it turned out that the sales cycle lasted 14 months, and the team had no experience with corporate tenders.

Positioning: how you differ in the buyer's eyes

Positioning is the decision about what place you want to occupy in the mind of a specific segment. In B2B, positioning answers the question of why a buyer should choose you rather than three other companies that do something similar.

In practice, positioning rests on one of four axes:

• Specialization: we do this one thing, but for a narrow group and better than anyone else.
• Cooperation model: for example, we charge for results, not for hours.
• Reach or locality: we are close by, we know the specifics of the region, we can be at the client's site within an hour.
• Experience: we have a specific number of implementations in the same industry behind us.

In our case, as an agency operating in Bydgoszcz, Toruń, Grudziądz and Inowrocław, positioning is based on two axes: geographic proximity and B2B experience. According to our internal data, we have 16+ years of work and 60+ clients behind us, and we manage a substantial volume of marketing budgets. This is a concrete fact that can be verified, unlike the statement "we are the best".

Good news: positioning does not have to be unique on a global scale. It is enough that it is clear within the segment. If in your segment no one clearly communicates that they charge for results, then this axis can be your advantage, even if the competition does the same, they just do not talk about it.

What the STP analysis looks like step by step

Below is a process that works in B2B companies employing from a few to several hundred people. You will complete the entire analysis within 4-6 weeks if you involve salespeople and someone from the management board.

Step 1: gathering data about current clients

Do not start with the market, start with your own base. Extract all clients from the last 24 months from the CRM and mark them according to firmographic, situational and behavioral criteria. Add information about the contract value, length of cooperation and acquisition cost. After this exercise, it usually turns out that 60-70% of revenue comes from one or two types of clients that no one had previously named.

Step 2: interviews with customers who bought and those who did not

At least 10 conversations. Questions: what was happening in the company when you started looking for a solution, what options did you consider, who was involved in the decision, what tipped the balance. Conversations with those who did not buy are just as valuable, because they show where your offer misses a real need.

Step 3: describing segments and their size

Each segment should have a name, a description, an estimated number of companies in the region, and the typical problem you solve. If you cannot estimate the size of a segment, it is probably too broad.

Step 4: choosing target segments

Choose one to three segments. More means none of them will get enough resources. For each chosen segment, define how many companies you want to win within a year and what budget you are allocating to it.

Step 5: aligning communication and offer

Only now do you change the website, sales materials, and campaigns. The order matters: if you start with the website, you will rewrite it three times.

The most common mistakes in the STP model in B2B marketing

From the perspective of the projects we have run, the same missteps keep repeating:

• Segments created on paper, without data. The team invents four segments in a workshop, but nobody checks how many companies actually exist in each of them and how many of them bought in the last two years.
• Positioning as a slogan, not as a decision. "Comprehensive solutions for business" is not positioning, because it excludes no one.
• No connection to the sales process. Segmentation stays in the presentation, and salespeople keep calling everyone. If you do not change the lead qualification criteria, the STP analysis will not work.
• Treating STP as a one-off project. The market changes, and so do segments. A review once a year is the minimum.
• Ignoring the buyer's perspective. Research on omnichannel indicates that the buyer's perspective is sometimes overlooked in strategic analyses, and it is that perspective that determines whether positioning is credible (Exploring Omnichannel Retailing, 2019, chapter 6.1).

The last point is especially important in B2B, where the purchasing decision rarely belongs to one person. If your positioning convinces the business owner but does not convince the procurement department, the deal will stall at the negotiation stage.

When STP analysis fails and what to do then

STP analysis is not a universal tool. It fails in three situations.

First, when the market is so narrow that segmentation makes no sense. A company manufacturing specialized machinery for three buyers does not need segment division, it needs relationships with those three buyers.

Second, when the company does not yet have a product suited to any segment. In that case, you first need to determine what you are selling, and only then to whom.

Third, when the input data is too weak. If the CRM contains 200 contacts with no information about industry, size, or purchase history, STP analysis will be guesswork. In that situation, it is worth filling in the CRM data first before making segmentation decisions.

If you run a company in a specific region and do not have someone on your team who can lead such a project, one option is an interim marketing manager paid on results. This is a model where an experienced person joins the company for a set period, conducts the analysis, and implements the conclusions, with compensation tied to the outcome rather than the number of hours. You can read more about how we combine STP analysis with B2B marketing strategy, in our service description.

Whether you do this yourself or with external support, one thing remains constant: until you decide who you are talking to, every dollar spent on marketing is a gamble, not an investment.
