How to write a homepage value proposition
A homepage value proposition is the headline and subhead at the top of your site. In a few seconds, they tell a first-time visitor what you do, who it's for and why to choose you over the alternatives. To write one, read the pages buyers compare you with, find the claim only you can make, say it in your buyers' words and back it with proof.
Most weak value propositions aren't wrong, just shared. If the same words sit on every competitor's homepage, a visitor has no reason to pick yours.
What a homepage value proposition does
Jakob Nielsen of Nielsen Norman Group, a user experience research firm, summarized a 2010 Microsoft Research study of visits to more than 200,000 web pages. People often left within 10 to 20 seconds. To hold them for minutes, he concluded, you must clearly communicate your value proposition within 10 seconds1.
In those seconds, the top of the page has to answer three questions: what is this, is it for me, and why this one?
The parts at the top of a homepage
| Part | What it holds | Example |
|---|---|---|
| Headline | What happens for the buyer, in one line | "When one job runs long, the rest of the day reschedules itself." |
| Subhead | Who it's for and how it works | "Dispatch software for heating and cooling contractors with 5 to 50 technicians." |
| Proof | One fact a buyer can check | "Dispatchers saved a median 6.2 hours a week across 41 customers." |
| Supporting points | Three capabilities, each with what it means for the buyer | "Texts every affected customer a new arrival time, so they know when to expect you." |
| Call to action | One next step that fits the visitor | "See a sample day" or "Book a 20-minute demo" |
Examples are illustrative, for a made-up dispatch software company.
Read the alternatives first
Begin with what buyers would do if you didn't exist. Positioning consultant April Dunford, who wrote Obviously Awesome, calls these options competitive alternatives2 and puts them first in her method. Sometimes the answer is "do nothing," which she says means sticking with the current way, such as a spreadsheet, a manual process or hiring an intern.
List the real alternatives
Name the three to five options buyers weigh against you, including the status quo. Ask sales which ones come up in deals.
Copy each page's words
Put every headline, subhead, section heading and button label in one sheet, yours included, with the date you read them.
Mark the shared words
Highlight any word or claim on two or more pages, such as "platform" or "all-in-one." Shared words can't carry your claim.
Note what nobody says
A buyer worry no page answers, or a result no one claims, is a good place to look for yours.
To see the field on one chart, a competitive positioning map plots you and each rival on the two attributes that separate you most.
Find the claim only you can make
Formulas give you a shape, not an answer. Dunford calls the classic positioning statement a sort of "Mad Libs" fill-in-the-blanks exercise2. It assumes each blank has one answer you already know, when most products could be positioned several ways.
Work through her questions in order instead. List what you have that the alternatives don't, then ask of each difference, "So what for customers?" The answer to keep is the one buyers care about most and no alternative can truthfully claim.
Check each candidate against what buyers have told you in win-loss notes, reviews and interviews. A customer discovery synthesis counts how many people raised each theme on their own.
Write the headline and subhead
Lead with what happens for the buyer, not your category. Michael Seibel, writing about investor pitches in Y Combinator's startup library, suggests walking people through the user path3. His example is Google: "We build a website with a box in it." Of the abstract "We organize the world's information by indexing the web," he writes, "With that description I'm lost."
- A specific capability beats a general benefit: "texts each customer a new arrival time" beats "a better customer experience."
- A number beats an adjective: "a median 6.2 hours a week" beats "dramatically faster."
- Your buyers' words beat yours: if they say "the 6 a.m. phone calls," so should you.
Before: The modern, all-in-one field service platform that streamlines your operations.
After: When one job runs long, the rest of the day reschedules itself.
Subhead: Dispatch software for heating and cooling contractors with 5 to 50 technicians. It moves the affected jobs, texts each customer a new arrival time and shows your dispatcher what changed.
- Drops the shared words. "Platform," "all-in-one" and "streamlines" could sit on any rival's page.
- Starts with a moment. The headline describes something the buyer lives through, not a category to decode.
- Names the buyer. The subhead says who it's for, down to the size of the crew.
Back every claim with proof
Three business professors, writing in Harvard Business Review in 2006, found that most value propositions make claims of savings and benefits without backing them up4. A business buyer, they wrote, will likely dismiss an undocumented claim as "marketing puffery."
In the US, the law asks for proof too. The Federal Trade Commission requires advertisers to have a reasonable basis for advertising claims before they are disseminated5. Wording raises the bar: a line that says "tests prove" needs at least the proof it advertises.
Not every line needs a file. The FTC's small business guide says subjective claims, or ones consumers can judge for themselves, get less of its attention6, citing "ABC Cola tastes great." Objective claims about performance, features, safety, price or effectiveness need proof you hold today, not proof you expect to have.
A claim-to-proof map
| Kind of claim | Line on the page | Proof on file | Verdict |
|---|---|---|---|
| Customer count | "Trusted by 500 contractors" | Billing shows 312 paying accounts | Blocking: change it to 312 |
| Comparison | "Faster to set up than any other dispatch tool" | None | Blocking: cut it, or time setups and date the result |
| Performance | "Saves dispatchers 6 hours a week" | Product data, 41 customers, January to June | Ships once it says "median" and shows the count |
| Opinion | "Built for the way your crew works" | Not needed | Ships |
Illustrative rows for the same made-up company. Put blocking rows first.
Naming a competitor is allowed, and it can be your clearest line. The FTC's policy statement on comparative advertising encourages the naming of competitors but requires clarity7, and it backs comparisons whose basis is clearly identified. Record what you compared, where you read it and when, then recheck it each quarter.
When to call a lawyer
Have a lawyer who knows advertising law review claims about health, safety, security or money before they go live. Do the same for any line that calls a named rival worse. Nothing here is legal advice.
Test it before it ships
Before launch, show only the top of the page to five people who match your buyer, for 10 seconds each. Then ask what the company does, who it's for and what they would click. If they can't answer in their own words, fix the words before you touch the design.
After launch, give every number and comparison a review date, since rivals change their pages and your own figures drift. When a claim needs a customer's words behind it, a case study from a customer interview puts them on the record.
Before you publish the page
- The headline says what happens, and the subhead says who it's for
- The headline's key words don't appear on rival pages
- Every objective claim has proof on file today
- Each comparison records its basis, source and date
- Five buyers could say back what you do
- There's one clear next step
To start from the page you have, paste it into the tool at the top of this page. It reads your competitors' pages beside yours and drafts the rewrite with every claim mapped to its proof.
How it works
Paste your page, or its address, and name the competitors buyers compare you with. River reads your page beside theirs and marks the words and claims you share. Then it rewrites your page around the one claim the others can't make, with its reasoning beside each section. Alongside, it builds a sheet tying every claim to its proof.
Add any proof you have, such as product data or a security report; otherwise River works from what you already publish, like case studies and customer counts. An unproven claim is marked as blocking, with a smaller version that's true today beside it. If you don't name competitors, River finds the three you're most often compared with and says why.
Paste your page
Paste the copy or its address, name the competitors buyers compare you with, and add any proof.
River compares the pages
It reads your page beside each competitor's and marks the words and claims more than one of you uses.
Get your rewrite
New copy, section by section with reasoning beside it, plus a sheet tying each claim to its proof.
Fix, test and share
Clear the blocking claims, ask for three headline tests or another page, then share it with your team.
What you get
- A table of your page beside your competitors' pages, with every shared word and claim marked
- The one claim only you can make, with the reason no competitor in the set can say it
- Your page rewritten section by section, with the reasoning beside each part so reviewers can argue with it
- A claim-to-proof sheet with each line, its kind of claim, its proof, who holds it and a verdict
- Claims your own data contradicts or can't support, marked as blocking with a version that's true today
- Every comparison with what was compared, where it was read, the date and when to recheck it
Common questions
What is a value proposition?
A value proposition is a short statement of what you offer, who it's for and why a buyer should choose it over the alternatives, including doing nothing. On a homepage, it is usually the headline and subhead. Unlike a slogan, which aims to be remembered, a value proposition has to be understood and believed within seconds.
How long should a homepage value proposition be?
Short enough to read in a few seconds: a one-line headline, a subhead of one or two sentences and one proof point nearby. If you need a paragraph to explain what you do, the claim isn't clear yet. Details belong further down the page, where interested visitors go looking for them.
How do I write a value proposition with River?
Paste your current page, or its address, into the box at the top of this page and name the competitors buyers compare you with. River reads your page beside theirs and finds the claim only you can make. It writes new copy and a claim-to-proof sheet into your free River workspace, where you can edit and share both.
Can I name competitors on my homepage?
In the US, yes, if the comparison is truthful and clear about what is being compared. The FTC's policy on comparative advertising encourages naming competitors. Keep a dated record of where each fact about a rival came from, recheck it when their pages change, and get legal advice before calling a named rival worse.
What if we don't have numbers to prove our claims yet?
Lead with specific capabilities until you do. "Texts each customer a new arrival time" is true the day the feature ships, while "cuts no-shows by 40%" needs data behind it. River marks unproven lines as blocking, writes a smaller version that's true today, and asks for the one piece of proof that would unblock the most important line.
Does it work for pages other than the homepage?
Yes. The tool also rewrites product pages, category or solution pages, pricing pages and competitor comparison pages, and works out which kind you pasted if you don't say. Every rewrite includes a claim-to-proof sheet, and you can ask River to rewrite another page of your site reusing the same proof.
Is the homepage value proposition tool free?
Yes, it is free to start. Your rewritten page and claim-to-proof sheet open in a River workspace, where you can edit them, share them or ask River to change them. Paid plans add more AI use and access to the most advanced models.
