A brand difference is strong enough to use in positioning when it is real in the business, matters to the buyer, is meaningfully distinguishable from credible alternatives, can be supported through evidence or customer experience, and can be expressed in language people can remember and repeat. If the difference only sounds impressive internally, depends on a claim the business cannot consistently deliver, or disappears when compared with competitors, it is not ready to carry the position.
A useful positioning difference has to survive five tests.
It should be real, relevant, distinct, supportable, and repeatable.
Real means the business actually does or delivers the thing. Relevant means the buyer has a reason to care. Distinct means credible alternatives cannot make the same claim with equal force. Supportable means the customer can encounter evidence for it. Repeatable means people can understand and remember the difference well enough to describe it later.
A clever phrase can fail all five tests. A seemingly ordinary operating practice can pass them.
The job is to find out which kind of difference you have before you build the brand around it.
Test 1: Is the difference already true in the business?
Barry LaBov's Genius Talk approach starts with discovery rather than invention. He encourages companies to identify the one, two, or three things they already do unusually well.
That is a useful first filter because positioning becomes fragile when marketing chooses a promise that operations have not earned.
A company may want to be known for speed, but approval still takes a week. It may want to claim unusual expertise, but the customer experience gives buyers no way to see that expertise. It may want to own personal service, but customers repeatedly interact with an anonymous queue.
Before polishing the words, ask:
- What do we actually do differently?
- Where does that difference show up in a real customer journey?
- Which internal practice creates it?
- Would employees who deliver the work recognize the claim?
- Can we point to an example without stretching the truth?
LaBov's perspective is valuable because it moves the discussion away from generic adjectives.
"Trusted," "innovative," and "high quality" may describe an aspiration. A specific practice that creates trust, innovation, or quality gives the buyer something more concrete to evaluate.
If the difference disappears the moment somebody asks, "What do you actually do that creates that?", it is not ready.
Test 2: Does the buyer care about it?
A real difference can still be strategically weak.
Your team may be proud of an internal process that customers barely notice. A technical feature may be unusual but irrelevant to the buying decision. A founder story may be distinctive without helping a buyer understand why the business is a better fit.
Customer relevance requires a second question:
What useful consequence does this difference create for the person choosing?
The answer should connect the difference to something the buyer values, such as lower effort, better judgment, less uncertainty, a stronger experience, faster recovery when something goes wrong, or a result the buyer is actively trying to achieve.
This is where customer research matters.
A difference becomes more credible as positioning material when customers independently notice it, value it, ask for it, mention it in feedback, or use related language when explaining why they chose or stayed with the business.
You do not need every customer to use the exact phrase the marketing team prefers. You do need evidence that the underlying distinction matters outside the building.
Test 3: Is it different in the competitive context?
Philip VanDusen recommends competitive audits so a company can understand how other businesses in the category present themselves.
For this question, the important principle is relational: a feature can be impressive and still fail as differentiation if every credible competitor offers it.
Take a proposed claim and place it beside the alternatives a buyer might realistically consider.
Then ask:
- Could the strongest competitor say the same thing?
- Do they already say it?
- Is our difference about a feature, a method, an experience, a specialization, a point of view, or some combination?
- Does the distinction remain visible after the category's standard claims are removed?
- Can a buyer tell why this company rather than another plausible option?
This is not a full competitive-audit exercise. The narrow task is to see whether the proposed difference survives comparison.
If every serious competitor claims "personal service," the phrase itself carries little differentiation. If your service model includes a concrete behavior that buyers can recognize and competitors do not appear to match, the underlying difference may still be useful.
The positioning should be built around the specific distinction, not the generic category word.
Test 4: Can customers experience the proof?
Ken Schmidt's Genius Talk work on reputation adds another threshold.
He frames brand thinking around questions such as what people currently say about the business, what the business wants them to say, and what it is doing to make that reputation real.
That makes customer experience a proof environment for positioning.
Suppose a business wants to be known for making a complicated purchase unusually simple.
Evidence might appear in the way information is organized, how quickly a customer understands the next step, how handoffs are handled, how questions are answered, or how problems are recovered.
The claim gains strength when the customer does not have to take the brand's word for it.
Bobby Gillespie similarly describes brand as reputation formed through repeated decisions over time. His perspective helps separate a positioning line from the operating behavior beneath it.
Marketing can name a difference. Repeated customer experience decides whether the difference becomes believable.
This does not require a dramatic case study for every claim. It does require some form of support, such as:
- a product characteristic a buyer can inspect;
- a service behavior the customer can experience;
- a process that reliably produces the stated advantage;
- customer language that reflects the distinction;
- relevant examples or demonstrations;
- a pattern of decisions consistent with the claimed reputation.
If proof only exists in the copy, the position is carrying too much weight.
Test 5: Can somebody remember and repeat it?
A difference can be true, valuable, and defensible yet still be hard to use in positioning because it takes five minutes to explain.
Schmidt's emphasis on what customers remember is useful here.
Ask a simple question:
If a satisfied customer were asked, "Why them?", what would you hope they say?
The answer should be specific enough to mean something and simple enough to survive retelling.
"Because they are a full-service, customer-centric, innovative partner" is easy to forget because it could describe many companies.
"Because they show you the risk in the project before they quote the work" is more concrete.
The final language can be more polished while keeping the underlying idea compact enough for a person to carry.
Repeatability is especially important because positioning works through accumulation. A business becomes easier to recognize when the same core distinction appears in messages, sales conversations, product experience, service, and customer stories.
Run a small message test before changing the whole brand
Once a difference passes the first five tests, test how well the market understands the expression of it.
The core question is not whether one headline "wins forever." It is whether the proposed difference is noticed, understood, and connected to something the buyer values.
Small tests can include:
- customer interviews using the new language without leading the participant;
- sales conversations that compare two ways of expressing the same difference;
- a landing page or campaign that isolates the positioning idea;
- asking recent customers what they remember after exposure;
- comparing whether people can accurately explain the distinction in their own words.
Bobby Gillespie's test-and-measure orientation adds a useful counterweight to consistency. A brand needs repetition to become recognizable, but consistency should not be used to protect a weak idea from evidence.
Keep the underlying difference stable long enough to learn. Test how clearly it is expressed. If buyers repeatedly misunderstand or ignore it, revisit the evidence rather than merely repeating the sentence louder.
A positioning-difference checklist
Before making a proposed difference carry the brand, ask:
- Reality: What in the business makes this true?
- Relevance: Why should the target buyer care?
- Distinctness: Which credible alternative can make the same claim?
- Proof: What can the customer see, experience, or verify?
- Repeatability: Can a customer explain it later in simple language?
- Consistency: Can the business deliver it across ordinary customer interactions?
- Testability: Can we expose the idea to the market without rebuilding the entire brand first?
A "yes" to all seven does not guarantee commercial success. It means the difference has enough substance to deserve a positioning test.
A weak answer to reality, relevance, or proof is more serious. In those cases, the problem is deeper than wording.
The most useful final test remains human.
When a customer explains why they chose you, is there a specific reason worth repeating?
If the answer is clear and the business can keep earning it, you have something positioning can work with.
