Market segmentation divides a market into groups with meaningfully different needs or buying situations. A target segment is the group you choose to prioritise. A persona describes a representative buyer; a platform audience is a targeting mechanism. Treating these as interchangeable can leave an attractive ad with no coherent service behind it.

BDC’s target-market definition connects customer selection with needs and commercial suitability. The worksheet here is our practical way to compare candidate groups. It comes before a 4Ps marketing-mix worksheet, which defines the offer and route to market after choosing whom to serve.

1. Start with a business question

Choose one service and one decision: for example, “Which type of customer should our next maintenance offer address?” State the service area, delivery capacity and any non-negotiable requirements. Do not begin by inventing a demographic profile because an advertising platform offers that filter.

Review existing enquiry reasons, order patterns, sales feedback and delivery requirements. BDC’s target-market guide recommends learning from current customers and understanding their buying needs before focusing your efforts. Keep observed evidence separate from assumptions about a new group.

2. Group by differences that change the offer

For a B2B service, useful differences might include the problem being solved, equipment covered, procurement process or required service window. A company-size label alone may not explain why two buyers need different messages.

Ask whether a segment changes the promise, proof, buying route or delivery requirement. If two proposed groups need the same offer and follow-up, separate marketing plans may add work without a useful distinction. Conversely, do not force customers with incompatible service needs into one generic message.

3. Use this fictional segment comparison

All entries below are assumptions for an invented maintenance provider. They are not research findings, a market-size estimate or CPCInsider client results.

The urgent-repair group is not automatically the best choice because the need is strong. If the business cannot reliably deliver urgent work, buying that traffic creates a mismatch. Likewise, a larger account can require a delivery system the team does not yet have.

4. Complete a selection worksheet

A numerical rating can organise discussion, but invented scores do not establish market attractiveness. Leave unknowns visible. Do not estimate demand by adding overlapping keywords, and do not treat a large social audience as a count of willing buyers.

5. Test the segment before broad expansion

Pick a small, reversible test with a spending boundary and suitable review period. For the fictional single-site offer, the test could be a clearer service page and an enquiry process that asks only what is needed for a scoped conversation. Keep essential qualification consistent.

Judge suitable enquiries, delivery workload, progression and customer economics together. A cheap lead is not automatically a profitable customer. Use the CPC, CPA and CAC comparison to keep cost denominators clear. With a small sample, inspect what happened and extend observation rather than asserting a proven winner.

6. Give the segment an owner

Record the chosen priority, the reasons, excluded situations and the next review. Share it with marketing, sales and delivery. A segment is useful only if the promise and handoff remain consistent after someone submits the form.

Once the group is chosen, map one concrete buying scenario with the customer-journey worksheet. That separates “who we serve” from “what this person needs to do next”.
