Value proposition
customer promiseA value proposition crystallises what value the customer gets and why they should choose you over the alternatives. A good one answers three questions at a glance: what you offer, for whom and what makes it better.
Good to know
The value proposition is the most important single text on your site: it is the first thing a visitor reads, and it decides whether they stay or leave. It is written in the customer’s language and as an outcome, not features: "a marketing team that grows your sales at a monthly price" says more than "a 360-degree digital agency".
The promise builds on positioning and becomes concrete with proof: a number, a customer or a guarantee makes the claim credible. The best test is the reversal test: if a competitor could say the same, the promise does not yet differentiate. It is also tested like any copy, because phrasing differences show directly in conversion.
IN PRACTICE
The structure of a working proposition
Headline: the outcome
What the customer gets, in their words: "A marketing team that grows your sales". No slogans, no jargon.
Clarifier: how and for whom
One or two sentences: what you do, for whom and with what model. The boundary makes the promise credible.
Proof: a number or a name
A customer count, a result or a known reference earns the claim at once: "+140 % leads in six months".
PITFALLS
Two value proposition mistakes
The promise is universal
"Quality, reliable service" fits everyone and separates no one. The reversal test exposes the empty words.
The promise talks features
Processes and tools are not value. The customer buys the outcome: time, sales, peace of mind.
FREQUENTLY ASKED
Frequently asked questions
Where does the value proposition appear?+
In the front page’s opening view, at the top of service pages, in sales decks and in ads. The same core promise everywhere, phrased per channel.
How is a value proposition tested?+
With an A/B test on the site’s headline, and by asking customers: what did you think we do based on this? Misreadings expose the ambiguities.
How long should a value proposition be?+
A headline under ten words, a clarifier of a couple of sentences. If the promise needs a paragraph, the position is still unclear.
Can a company have several value propositions?+
One core promise and per-segment applications: the same value in each audience’s words. Several diverging promises signal a missing choice.
How do I know the promise works?+
Conversion improves, sales conversations start on the right topics and customers repeat the promise in their own words. That is the sign the message landed.
