How to Write a USP
Find the Claim Nobody Else Can Make, Then Prove It
Short answer
A USP is one claim buyers value that no rival can truthfully make. To find it, list every claim your competitors make, mark which ones you can also make, and look for the valuable claim only you can make. Test it with the "only" sentence, check you can prove it, then phrase it for buyers.
1. What is a USP, and where did the idea come from?
A USP is the single, specific reason a customer picks you over competitors: one promise rivals cannot credibly make. The idea comes from Rosser Reeves, who argued that every ad should make one distinct, strong proposition.
- Unique selling proposition (USP)
- The single, specific reason a customer picks your brand over competitors, expressed as one promise that rivals cannot credibly make.
- Also known as: Unique selling point, Unique value proposition
- Full definition of Unique selling proposition (USP)
Rosser Reeves, an advertising executive at Ted Bates and Company, popularized the concept and set it out in his 1961 book Reality in Advertising [s2]. His three criteria still work as a checklist: the ad must make a real proposition to the buyer, not just praise the product; the proposition must be one competitors cannot or do not offer; and it must be strong enough to move people to buy [s1].
Those three criteria are a good filter for small companies too, with one practical change. Reeves was writing about mass-market brands where a single claim reached millions. A small company's USP only has to be unique among the alternatives its buyers actually consider, which is usually three to six options, including doing nothing.
2. Where can a small business find a USP?
From six places: a narrow specialism, a pricing model, a guarantee, a process, speed, or a refusal to do something rivals do. Unique technology is only one source, and often the easiest to copy.
| Source | Example claim (invented) | How hard to copy |
|---|---|---|
| Narrow specialism | The only booking system built around treatment courses for physio clinics | Hard for a generalist without abandoning other markets |
| Pricing model | One flat price per clinic, no per-practitioner fees | Easy to copy, but costly for rivals whose revenue depends on seats |
| Guarantee | Live the same afternoon, or the first month is free | Medium: rivals must be able to deliver it |
| Process | Every new clinic gets its diary imported for them | Medium to hard, because it costs time at scale |
| Speed | Replies from a physio-trained support person within the hour | Hard to sustain as rivals grow |
| Refusal | No contracts, no setup fees, no clinical records module | Hard for rivals who make money from what you refuse |
Refusals deserve more attention than they get. Saying what you will not do is often more believable than saying what you do, because it costs you something. A clinic owner who has been burned by a year-long contract hears "no contracts" as a real difference, while "best-in-class support" sounds like everyone else.
3. How do I find a USP from what competitors already claim?
Build a claim inventory: list every claim on each competitor's homepage, pricing page and current ads, mark which ones you can also make, then look for claims buyers value that only you can make. That empty space is your USP candidate.
- Collect every claim, word for word. For each direct competitor, copy the homepage headline, subhead, feature page headings, pricing page promises and the claims in their live Meta and Google ads. Aim for ten to twenty claims per competitor.
- Group identical claims. Merge claims that say the same thing in different words. "Easy to use", "simple" and "intuitive" are one claim. You will usually end with fifteen to twenty-five distinct claims across the whole market.
- Mark who can truthfully make each one. Fill a grid with a column per alternative, including yours and the status quo. Mark each claim yes or no based on what is true, not what is advertised.
- Add a column for buyer value. For each claim, note whether buyers mention it in your win reasons, sales calls or rival reviews. A claim only you can make but nobody cares about is trivia, not a USP.
- Pick the row with only your yes and high value. Your USP candidates are the claims where you are the only yes and buyer value is high. If there is none, you need to build one, usually by specializing or by adding a guarantee.
| Claim | You | Veltrix | Sondera | Phone and diary | Buyers care? |
|---|---|---|---|---|---|
| Easy to use | Yes | Yes | Yes | Yes | Yes, but everyone claims it |
| Online booking 24/7 | Yes | Yes | Yes | No | Yes |
| Automatic reminders | Yes | Yes | Yes | No | Yes |
| Clinical records | No | Yes | No | Paper | Only larger clinics |
| Book a whole treatment course at once | Yes | No | No | No | Yes, mentioned in most wins |
| Live the same afternoon | Yes | Yes | No | Yes | Yes |
| Card payments at booking | No | Yes | Yes | No | Some |
4. How do I phrase the USP once I have found it?
Start from the "only" sentence: we are the only [alternative type] that [claim] for [buyer]. Check it is true and provable, then rewrite it in the buyer's words for public use. The "only" sentence stays internal.
| Version | Template | Clinic booking example |
|---|---|---|
| Internal test sentence | We are the only [type of alternative] that [claim] for [buyer] | We are the only booking system that lets physio patients book their whole treatment course at once |
| Public, benefit-led | [Value the claim creates] with [the claim] | Patients stay for the whole course, because they book it all at once |
| Public, contrast-led | Other [alternatives] [what they do]. We [claim] | Other booking tools book one visit at a time. We book the whole course |
Be careful with "only", "first" and "best" in public copy. They are objective claims, and advertising claims need evidence behind them before you publish [s3]. Keeping the literal "only" sentence as an internal test and publishing a benefit-led or contrast-led version is usually both safer and more persuasive.
Is a USP the same as a value proposition?
No. The USP is the one claim only you can make. The value proposition states what the buyer gains compared with their alternative, often built on the USP. In the example, your USP is course booking; your value proposition is that clinics keep patients for the whole course without answering the phone.
5. How do I keep a USP unique once competitors notice?
Assume any successful claim will be copied, and watch for it. Recheck the claim inventory each quarter, and when a rival starts making your claim, either deepen the difference or move to the next row.
A USP that works is visible, and visible claims get copied. The warning signs are public: a competitor adds a feature page for your specialism, starts using your words in ads, or changes their homepage headline toward your claim. Those changes usually appear before anyone mentions them in a sales call.
There are two responses. Deepen the claim, so the copy looks thin next to yours (course booking becomes course booking with automatic rebooking when a patient cancels). Or move to the next strongest row in the inventory. What does not work is continuing to claim uniqueness after it has gone; buyers will find the rival's page.
Oppira keeps Differentiation and Value Propositions as layers of your playbook and watches competitors' landing pages, ads and posts. When a tracked rival starts using a claim close to yours, the agent proposes an edit with the evidence attached, so rechecking the inventory becomes a response to a signal rather than a quarterly chore.
Key Takeaways
Unique among the real alternatives
A small company's USP only has to be unique among the three to six options its buyers actually consider, including doing nothing.
Technology is only one source
Specialism, pricing model, guarantee, process, speed and refusals are all sources, and several are harder to copy than a feature.
Build a claim inventory
List every rival claim, mark who can truthfully make each, add buyer value, and look for the row where only you say yes.
Use the "only" sentence as a test
Keep the literal "we are the only" sentence internal. Publish a benefit-led or contrast-led version you can prove.
Refusals are believable
Saying what you will not do costs you something, which makes it more credible than another superlative.
Expect to be copied
Watch for rivals adopting your claim, and either deepen the difference or move to the next row.
